| Abstract: | This paper shows the key, yet overlooked, role played by the legacy of a high inflation history on the strength of the monetary policy response to inflationary shocks. To rationalize this, we propose a New Keynesian model that diverges from the existing workhorse model by adding path-dependence (to a forward-looking model) and potentially imperfect central bank credibility. We show that achieving low inflation (hitting the target) requires more aggressive monetary policy reactions, and is costlier from an output point of view, when individuals’ past inflationary experiences shape their inflation expectation formation. In turn, we provide empirical evidence of the need for these two theoretical additions. Countries that experienced a high level of inflation before adopting the IT regime tend to respond more aggressively to deviations of inflation expectations from the central bank’s target. We also point to the existence of a credibility puzzle, whereby the strength of a central bank’s monetary policy response to deviations from the inflation target remains broadly unchanged even as central banks gain credibility over time. Put differently, a country’s inflationary past casts a long and persistent shadow on central banks. |

| Abstract: | We study how the transmission of monetary policy innovations is affected by the endogenous response of the central bank to macroeconomic aggregates in a two-agent New Keynesian model. We focus on how the stance of monetary policy and the fraction of savers in the economy affect transmission. We show that the indirect effect of an innovation is negative when the indirect real rate effect exceeds the indirect income effect. The relative magnitude of the indirect real rate effect increases with the share of savers and the strength of the central bank’s response and decreases with the horizon of the innovation. |

| Abstract: | The financial situation of households differs substantially across countries, but the implications of this heterogeneity are still vastly understudied. We examine the implications of this asymmetry for optimal monetary policy in a currency union. We build a two-country monetary union model with heterogeneous households leading to inequality due to imperfect insurance. Money is introduced through central bank digital currency (CBDC) as a liquid asset to self-insure against idiosyncratic risk. CBDC is a new instrument which allows the central bank to target heterogeneity within a monetary union. We derive a welfare function with two additional objectives, consumption inequality within and across countries. The more heterogeneous households are, the less important inflation stabilization becomes in favor of stabilizing consumption inequality through providing money. Our research provides important policy implications as we show that it is beneficial for a monetary union to have a country-specific instrument to compensate for country differentials. |

| Abstract: | Under inflation forecast targeting, central banks such as the ECB adjust policy to keep expected inflation on target. We evaluate the ECB’s inflation forecasts: they are unbiased and efficient but contain little information at forecast horizons beyond three quarters. In a New Keynesian model with transmission lags, inflation forecast targeting is indeed effective in stabilizing inflation—provided there is no forward-looking behavior—though the information content of forecasts is unrealistically high. In the presence of forward-looking behavior, the information content declines because monetary policy becomes more effective in meeting the target, but inflation is best stabilized by targeting current inflation. |

| Abstract: | Subdued economic activity and low tax revenues, especially during crises, drive borrowing and increase public debt. During these periods, to ease the debt burden, central banks may face pressure to deviate from policy targets. Under fiscal dominance, debt sustainability relies on low interest rates and high inflation rather than consolidation. This paper empirically tests the presence of fiscal dominance using forward-looking Taylor rules and data from 52 economies over 3 decades. The results detect fiscal dominance, with stronger effects in de jure inflation-targeting emerging economies with low central bank independence, especially those without debt rules and with high debt-to-gross domestic product ratios. Emerging economies with high foreign currency-denominated debt are further affected by exchange rate debt valuation effects, and fiscal dominance leads their central banks to follow exchange rate stabilization policies. Since 2022–2023, interest rate responses to fiscal imbalances have strengthened, posing challenges for future policy. |

| Abstract: | Both the magnitude and the pace of monetary policy tightening in the euro area during 2022-23 were historically large and fast. Yet, the real economy proved to be resilient. In this paper, we analyze the pass through of the ECB’s changes in the policy rate to mortgage rates in Finland during the post-pandemic period of 2022-23, when the policy liftoff began at the negative interest rate territory, using the normal tightening cycle in 2006-08 as control. We use monthly data and three different empirical methodologies: event studies, high-frequency identification, and exposure-measure regressions. Our evidence suggests that the post-pandemic monetary policy transmission was significantly less effective than during the control period, implying that for the same amount of tightening in financial conditions, a bigger increase in the policy rate is needed. The loss in monetary transmission during the negative interest rate policy is also playing out when monetary policy changes course. Thus, while monetary policy remains effective in the negative interest rate territory, it creates headwind for policy normalization down the road. |

| Abstract: | Quantitative easing (QE) has been criticized for helping fuel the post-COVID inflation boom and causing large central bank losses. In this paper, we argue that QE should be evaluated mainly on its ability to achieve core macro-objectives as well for its effects on the consolidated fiscal position of the government and central bank, although central bank losses can matter to the extent that they may weaken central bank credibility. Using a DSGE model with segmented asset markets, we show how QE can provide a sizeable boost to output and inflation in a deep liquidity trap and can reduce public debt substantially. This contrasts to the rise in public debt that occurs under fiscal expansion and makes QE an attractive tool in a high debt environment. There is more reason for caution in using QE in a “shallow" liquidity trap in which the notional interest rate is only slightly negative: QE runs more risk of causing the economy to overheat, especially if forward guidance has a strong element of commitment, and is more likely to generate sizeable central bank losses. Some refinements in strategy, including the use of escape clauses, can help mitigate overheating risks. |

| Abstract: | A predominant share of employment in EMDEs is in the informal sector. In 2019-2020, approximately 72% of total employment was in the informal sector in India, with casual employment comprising 22% and self-employment comprising 50%. How does informality in labor markets affect inflation stabilization and monetary policy setting? To address this, we build a medium-scale NK-DSGE model with segmented labor markets and search and matching frictions. We calibrate the model to India. As in the data, we divide informal employment into self-employment and casual employment. We show that more formality improves the transmission of monetary policy. We show that a contractionary monetary policy shock leads to a decline in both formal and informal employment (self and casual), suggesting that monetary policy's impact on output and inflation works through informal labor markets as well. Our paper highlights the mechanism behind the transmission of monetary policy in the presence of heterogeneous labor markets. |

| Abstract: | Central banks around the world routinely engage in asset purchases in secondary markets as part of implementing monetary policy or enhancing market liquidity, but the effects of such interventions are not yet fully understood. We develop a multi-asset general equilibrium model in which the liquidity of an asset is endogenous and depends on the terms of trade in each asset's respective secondary market, which are, in turn, driven by agents' market entry decisions and the possibility of central bank intervention. We use our model to qualitatively and quantitatively rationalize the superior liquidity of U.S. Treasuries over corporate bonds of comparable safety. Our model highlights and quantifies an unexplored link between fiscal and monetary policy: central bank interventions in the market for Treasuries increase secondary market liquidity for these securities, thus indirectly aiding the Treasury to borrow at lower rates. Our results also reveal that central bank interventions can have spillover effects on markets where the bank does not participate, offering a cautionary note to both policymakers and empirical researchers. |

| Abstract: | The current 5-year review of the FOMC’s Statement on Longer-Run Goals and Monetary Policy Strategy provides an opportunity to assess the revisions made in 2020. I review the rationale behind the 2020 revisions and then discuss the new operational objectives: asymmetric average inflation targeting and shortfalls from maximum employment. Macroeconomic developments since 2020 led to an environment that was very different than the one anticipated when the 2020 policy framework was adopted. In this new environment, the 2020 changes created a risk that the US would suffer a repeat of the 1970s, a risk compounded by the FOMC’s slow reaction as inflation rose during 2021-2022. I illustrate the consequences of such a delay in addressing high inflation. The experience of the past five years offers some new lessons for the current review of the policy framework, as well as reinforcing the importance of some old lessons. |

| Abstract: | This paper studies the role of financial intermediaries in the transmission of central bank corporate bond purchases to bond yields. Contrary to standard expectations, we find that mutual funds—typically viewed as price-elastic investors—amplify, rather than dampen, the effects of these interventions on bond spreads. Following the ECB’s corporate bond purchase announcements in 2016 and 2020, bonds predominantly held by mutual funds experienced significantly larger and more persistent declines in spreads compared to those held by price-inelastic investors such as insurance companies, even after controlling for a broad set of bond characteristics. Drawing on additional empirical evidence and an equilibrium asset pricing model, we show that the state-contingent nature of the policy reduces perceived market risk for procyclical investors like mutualfunds, thereby boosting demand and compressing risk premia.

| Abstract: | This paper examines the transmission of U.S. monetary policy shocks to bank lending in 12 Latin American countries between 2000 and 2020. Using data from 118 banks, we find evidence of an international bank lending channel, even in countries with low direct exposure to U.S. banks. Crucially, the strength and direction of this transmission depend on the degree of financial dollarization. While U.S. tightening is, on average, associated with rising credit, in more dollarized economies it leads to slower loan growth. These findings underscore the vulnerability of dollarized banking systems and point to the need for strengthened local macroprudential and supervisory frameworks. |

| Abstract: | Theory suggests that in the face of fire sale externalities, banks have incentives to overinvest in order to issue excessive money-like deposit liabilities. The existence of a private market for insurance such as contingent capital can eliminate the overinvestment incentives, leading to efficient outcomes. However, it does not eliminate fire sales. A central bank that can infuse liquidity cheaply may be motivated to intervene in the face of fire sales. If so, it can crowd out the private market and, if liquidity intervention is not priced at higher-than-breakeven rates, induce overinvestment. We examine various forms of public intervention to identify the least distortionary ones. Our analysis helps understand the historical prevalence of private insurance in the era preceding central banks and deposit insurance, their subsequent disappearance, as well as the continuing incidence of banking crises and speculative excesses. |

| Abstract: | This paper estimates the strength of monetary policy transmission to bank lending rates in Brazil. We identify monetary policy shocks using forecast errors from Brazi’s daily Focus survey of professional forecasters. We then estimate the pass-through to lending rates based on an instrumental variable application of local projections and find an aggregate pass-through of 70 percent after four months, reflecting full passthrough to market-based lending rates and 20 percent to government-directed credit interest rates. Analysis using bank-level data reveals varying degrees of pass-through across credit types, from 40 percent for payrollbacked loans to 80 percent for working capital loans, and stronger pass-through for larger banks. Estimated pass-through has increased since 2020 due to more responsive corporate loans |

| Abstract: | This study updates the Costa Rica’s natural real interest rate (NRIT) estimate for the period between 2010’s first quarter and 2023’s third quarter. I use two different methodologies for this estimation: Holston, Laubach and Williams (2023)’s semi-structural model and a structural VAR proposed by Brzoza-Brzezina (2002). This study’s methodological contribution is to estimate an extension of Holston-Laubach-Williams framework to incorporate conditions that are inherent in an open and small economy. The main result is that the natural real interest rate has oscilated between 1, 18% and 1, 47% during the period in analysis, and has been in the interval between 1, 36% and 1, 44% after 2022. Further, I check that the real interest rate gap correlation with other economic variables, like output gap, inflation and real exchange gap, shows a sign that is expected. Finally, I conclude that the Central Bank’s monetary policy has been consistent with its objective of maintaning a low inflation. |

| Abstract: | A puzzling characteristic of post-pandemic Indian inflation is the fall, within 10 years of adopting flexible inflation targeting (IT), in core inflation to lifetime lows despite high growth and recurrent commodity price shocks. Establishing the credibility of IT is expected to take time in emerging markets (EMs) since prerequisites are thought to include independent central banks (CBs) that focus only on inflation, giving up other types of intervention. The Indian CB, however, continued foreign exchange intervention and its coordination with the government improved over the period. Even so, our evidence from multiple exercises with a disaggregated industry panel suggests firms pass-through of supply shocks reduced in the IT period. The results support the effectiveness of the communications and expectations channel in EMs compared to other channels. EM features imply prerequisites for successful IT may not be the traditional ones. Flexible inflation targeting, with procedures adapted to the context, can reduce growth sacrifice while lowering inflation. |

| Abstract: | The literature expects it to take a long to establish inflation targeting (IT) in emerging markets, but the Indian experience suggests that suitable adaption of IT to domestic structure and shocks as well as circumstances can fast-track the process while reducing growth sacrifice. The paper provides evidence and possible further refinements. Key features that worked well were flexible implementation, unlike the pre-pandemic over-strictness; counter-cyclical smoothing of shocks with real rates near equilibrium; good fiscal-monetary coordination with independence in rate-setting; use of complementary prudential regulation and liquidity management; establishing adequate independence from global cycles. The IT framework needs to preserve these features. Use of better inflation data, more transparency and accountability in inflation forecasts and in liquidity management would improve outcomes. |

| Abstract: | Embedding seigniorage and transaction process into the RBC model, this paper proposes a new monetary economy, seigniorage channeled monetary economy, briefly SCME, in which monetary shocks can affect the real variables effectively and persistently in flexible price conditions. The mechanism of the effectiveness is the resource occupation effect of money issuance, in other words, money is a public goods and new money issuance is a form of taxation. The preliminary applications of SCME have clearly explained some notable puzzles or hotly debated issues in empirical studies, such as the price puzzle, the missing liquidity effect, the best inflation rate, the negative movement of hours under a positive technology shock, and the Friedman rule. In addition, we obtained interactive pricing, origin of money market interest rate, the best money market interest rate, and the best tax rate (in other words, the best government debt level) in this paper, and there is no forward guidance puzzle in SCME. Because resource allocation in the unique equilibrium of SCME is Pareto optimal, which is starkly different from the existing theories' sub-optimal result for the monetary and fiscal economy, a profound consequence of SCME is that it is a proof of the Invisible Hand Conjecture of Adam Smith in the economy with tax and money. |

| Abstract: | With the advancement of digital payment technologies, central banks worldwide have increasingly begun to explore the implementation of Central Bank Digital Currencies (CBDCs). This paper presents a comprehensive review of the latest developments in CBDC system design and implementation. By analyzing 135 research papers published between 2018 and 2025, the study provides an in-depth examination of CBDC design taxonomy and ecosystem frameworks. Grounded in the CBDC Design Pyramid, the paper refines and expands key architectural elements by thoroughly investigating innovations in ledger technologies, the selection of consensus mechanisms, and challenges associated with offline payments and digital wallet integration. Furthermore, it conceptualizes a CBDC ecosystem. A detailed comparative analysis of 26 existing CBDC systems is conducted across four dimensions: system architecture, ledger technology, access model, and application domain. The findings reveal that the most common configuration consists of a two-tier architecture, distributed ledger technology (DLT), and a token-based access model. However, no dominant trend has emerged regarding application domains. Notably, recent research shows a growing focus on leveraging CBDCs for cross-border payments to resolve inefficiencies and structural delays in current systems. Finally, the paper offers several forward-looking recommendations for future research. |

| Abstract: | This paper examines the drivers of money market funds (MMFs) growth during monetary policy hiking cycles. Analyzing data from nine countries with notable MMF sectors post-pandemic, it examines three main drivers: yield differentials between MMFs and bank deposits, banking turmoils that affect perceptions of relative safety for traditional cash options, and structural characteristics (types) of MMFs. The findings indicate that MMFs attract capital during rising interest rates driven primarily by yield-seeking behavior. This pattern persisted following the 2023 banking turmoil, particularly in the U.S., where yield remained the dominant driver. After accounting for yield differentials, MMF growth was not unusually high compared to previous hiking cycles, suggesting limited evidence of widespread flight-to-safety flows. Moreover, when MMF yields rise, investors in the US and the euro area increasingly favor private debt MMFs, likely due to their higher yields. The study underscores the trade-off between safety and yield in investor behaviour, providing insights for policymakers on enhancing financial stability. |

| Abstract: | Climate change, environmental degradation, and global energy markets are all sources of price instability, with important implications for inflation forecasting and macroeconomic policy. Central banks will have to deepen their understanding of these drivers of inflation and adapt their policymaking accordingly, recognising that achieving environmental targets is necessary to avoid persistent environmentrelated macroeconomic instability. While primary responsibility for the transition to a sustainable economy lies with fiscal, industrial, and environmental authorities, new approaches to monetary policy and improved inflation forecasting should support these efforts. Energy’s relevance to price stability is widely acknowledged, as fossil fuel prices driving inflation (‘fossilflation’) is a longstanding phenomenon, most recently triggered by Russia’s invasion of Ukraine. The inflationary effects of climate change (‘climateflation’) and environmental degradation in a modern context are comparatively novel though increasingly pronounced. Climateflation, which is global in nature yet borne disproportionately by lower income households and countries, occurs primarily through reductions in agricultural activity and damage to crop yields. As environmental disruptions intensify, they will play an increasingly significant role in driving price instability. In this context, orthodox monetary policy is counterproductive to achieving price stability, as well as governments’ economic, social and environmental objectives. Increasing interest rates fails to address the core drivers of rising energy and food prices, disproportionately hampers investment in capital-intensive green projects, and reduces government’s fiscal space. Instead, central banks should factor environmental considerations into the conduct of monetary policy and explore greater macroeconomic policy coordination with fiscal and industrial authorities. New international monetary arrangements will also be necessary to secure price stability and a just transition. |

| Abstract: | This paper develops a new generation of the Keynesian Intertemporal Synthesis (KIS) Model, a macroeconomic framework designed to reconcile the empirical strengths of the Post-Keynesian (PK) and New Keynesian (NK) traditions. The central innovation of this work is the abandonment of the traditional Cobb-Douglas production function in favor of a Constant Elasticity of Substitution (CES) specification. This modification is directly motivated by the compelling evidence from the meta-analysis by Gechert et al. (2021), which emphatically rejects the hypothesis of a unit elasticity of substitution between capital and labor. We integrate this finding with the conclusions from a wide range of meta-analyses on the state-dependent heterogeneity of fiscal multipliers (Gechert and Rannenberg, 2018), the productivity of public capital (Bom and Ligthart, 2014), the effectiveness hierarchy of spending instruments (Gechert, 2015), and the empirical failure of Ricardian Equivalence (Stanley, 1998). The resulting KIS-CES model, while based on intertemporal optimization, incorporates household heterogeneity, non-standard preferences that value wealth and penalize debt, and a monetary policy constrained by the zero lower bound. The mathematical derivations reveal that the elasticity of substitution, calibrated to an empirically plausible value of $\sigma |

| Abstract: | Foreign exchange markets are not merely venues for speculative profit—they are systemic transmitters of macroeconomic stability and instability. Volatile currency regimes can exacerbate trade imbalances, distort capital flows, and trigger policy interventions that carry long-term consequences for national economies. Yet, much of the existing algorithmic trading infrastructure remains tethered to predictive fragility, relying on static indicators that collapse under regime shifts and volatility clustering. Praxis Core introduces a structural intelligence framework that reframes FX execution as an adaptive, state-aware process directly aligned with macroeconomic stability objectives. By integrating a four-state Markov-Switching GARCH model—Bayesian-smoothed to stabilize rare transitions—with dual volatility and orderflow memory processes, Praxis Core detects and responds to regime mutations before they cascade into macro-level dislocations. Execution is anchored not to arbitrary price triggers, but to structural market topology—liquidity-depth contours, volatility surface curvature, and macro-sentiment alignment—ensuring trades are positioned where they absorb, rather than amplify, systemic stress. Risk is adaptively modulated using non-Gaussian tail modeling, regime-weighted sizing, and memory-aware throttling, preserving capital during high-impact macro events such as central bank interventions or geopolitical shocks. With a compliance-grade cryptographic audit layer, atomic-time synchronization, and fully transparent decision logic, Praxis Core offers a verifiable, institution-ready mechanism that bridges microstructure precision with macroeconomic responsibility. In doing so, it positions FX execution not only as a profit engine but as a stabilizing force—capable of mitigating spillover volatility that would otherwise propagate through global trade and investment channels. |

| Abstract: | This study follows the monetary approach to estimate the pass-through of the Monetary Policy Rate (MPR) of the Central Bank of Costa Rica to market interest rates, liquidity markets and the yield curve. Cointegration, error correction vector and autoregressive vector models are used. Unlike previous studies on this topic, this research uses weekly data on negotiated active interest rates according to economic activity, and negotiated deposit rates, classified by deposit term. The results show that the pass-through of the MPR to active and passive interest rates is heterogeneous and incomplete; in addition, the speed of the pass-through is greater than that shown in previous studies. In general, it is confirmed that the pass-through is faster to passive rates than to active rates. It is found that, for consumer rates, the pass-through is not statistically significant, while towards passive rates the transfer is stronger and faster in the terms of greater demand. Este estudio sigue el enfoque monetario para estimar el traspaso de la Tasa de Política Monetaria (TPM) del Banco Central de Costa Rica a las tasas de interés del sistema financiero, los mercados de liquidez y la curva de rendimiento. Se utilizan modelos de cointegración, de vectores de corrección de errores y vectores autorregresivos. A diferencia de estudios previos sobre este tema, en esta investigación se utilizan datos semanales de las tasas de interés activas negociadas según actividad económica, y de las tasas pasivas negociadas, clasificadas por plazo del depósito. Los resultados muestran que el traspaso de la TPM hacia las tasas de interés activas y pasivas es heterogéneo e incompleto; además, se evidencia una mejora en la velocidad de la transmisión si se le compara con estudios anteriores. En general, se confirma que el traspaso es más rápido hacia las tasas pasivas que a las tasas activas. Se encuentra que, para las tasas de consumo el traspaso no es estadísticamente significativo; en tanto que hacia las tasas pasivas el traspaso es más fuerte y rápido en los plazos con mayor demanda. |

| Abstract: | We study the effects of movements in aggregate lending standards on macroeconomic aggregates and inequality. We show in a New Keynesian model with heterogeneous households and housing that a looser loan-to-value (LTV) ratio stimulates housing demand, nondurable consumption, and output. Our model implies that the LTV shock transmits to macroeconomic aggregates through higher household liquidity and a general-equilibrium increase in house prices and labor income. We also show that a looser LTV ratio redistributes housing wealth from the top 10% of the housing wealth distribution to the bottom 50%, indicating an overall decrease in inequality. |

| Abstract: | There was a significant increase in housing prices and household debt during the Covid-19 pandemic in Canada, even though both output and consumption experienced severe contractions. While a shift in household preferences toward housing---largely driven by increased demand for work-from-home arrangements---appears to be the primary driver of rising housing demand, various pandemic-related policy interventions may also have contributed to these trends. In this paper, we employ a medium-scale DSGE model calibrated to Canadian data to assess the contribution of pandemic-related support policies, including fiscal, monetary, and credit measures. Our findings indicate that these policies played a key role in driving the housing market boom during the pandemic, accounting for approximately 45 percent of the observed increase in household debt. In the case of housing prices, the model explains about 40 percent of the observed rise, although it fails to replicate the gradual increase observed in the data, instead predicting a more immediate rise. |

| Abstract: | Banking sector distress can be highly disruptive, with substantial implications for financial intermediation and economic growth. Given their disruptive effects, country authorities have often relied on public funds to safeguard financial stability when confronted with systemic crises. The global financial crisis, for example, prompted governments to provide substantial support to ailing banks, in the absence of other credible policy options for stabilizing their financial systems. While policymakers have subsequently sought to reduce the need for such bailouts, including through the establishment of a new international standard for resolution regimes (that is, the Key Attributes of Effective Resolution Regimes), it is understood that under exceptional circumstances, the provision of solvency support may still be needed; notably, when the initiation of resolution procedures in the midst of systemic distress could generate confidence shocks and or fuel contagion. Against this backdrop, this note provides guidance on the design and implementation of arrangements for providing exceptional public solvency support as a “last resort” option. Among others, it discusses (i) the role of solvency support in crisis management and bank restructuring programs; (ii) minimum conditions and key modalities for solvency support; and (iii) governance and shareholder management arrangements for temporary government investments in the financial sector. |

| Abstract: | Sovereign bonds are central to aligning finance flows with the net zero transition required to meet the Paris Agreement temperature goals. This report aims to understand the system-wide context within which central banks can make a responsible contribution to this alignment. It reviews market innovations and challenges, considers existing practice and sets out robust options for action. |

| Abstract: | In this study, we attempt to construct an overlapping generations model designed to theoretically analyze the macroeconomic situation of sub-Saharan African countries. Our aim is to examine the conditions necessary for the effective functioning of infrastructure development financed by seigniorage and monetary control policies in some sub-Saharan African countries with stagnant macroeconomic performance. We also consider the implications of our model in terms of inflation and population aging. As a result, when the government selects the monetary growth rate that maximizes the long-term growth rate of gross domestic product (GDP), the absolute value of the monetary growth rate elasticity of the private capital--public capital ratio must be equal to the reciprocal of the private capital elasticity of GDP, which is greater than 1. Thus, seigniorage per se is not the cause of economic stagnation in some sub-Saharan African countries. If maximizing social welfare is equivalent to maximizing the long-term growth rate of GDP in terms of selecting the public investment share, then the public investment share elasticity of the private capital--public capital ratio is zero. Moreover, when the initial value of the private capital--public capital ratio is sufficiently low (high) level, inflation (deflation) occurs during the transition process to a steady state. Furthermore, population aging does not necessarily constitute a bottleneck for economic growth in sub-Saharan African countries. |

| Abstract: | This technical note describes the procedure currently used by the Central Bank of Costa Rica (BCCR, by its initials in Spanish) to conduct stress tests on the portfolios of financial entities. The analysis identified two opportunities for improvement compared to the current practice; a procedure that was implemented as part of a technical assistance provided by the IMF. First, the stress tests are calculated based on the estimation of the PAR yield curves in colones and dollars carried out by the BCCR, which better reflect the behavior of the Costa Rican market. Secondly, resampling methods are used to determine the loss distribution based on available data, rather than using only predefined shocks, which facilitates the comparison of the predefined shocks currently used with the actual observed events. In conclusion, it is recommended to implement these two improvements in the execution of the stress tests. |

| Abstract: | Stablecoins, with a capitalization exceeding 200 billion USD as of January 2025, have shown significant growth, with annual transaction volumes exceeding 10 trillion dollars in 2023 and nearly doubling that figure in 2024. This exceptional success has attracted the attention of traditional financial institutions, with an increasing number of governments exploring the potential of Central Bank Digital Currencies (CBDCs). Although academia has recognized the importance of stablecoins, research in this area remains fragmented, incomplete, and sometimes contradictory. In this paper, we aim to address the cited gap with a structured literature analysis, correlating recent contributions to present a picture of the complex economic, technical, and regulatory aspects of stablecoins. To achieve this, we formulate the main research questions and categorize scientific contributions accordingly, identifying main results, data sources, methodologies, and open research questions. The research questions we address in this survey paper cover several topics, such as the stability of various stablecoins, novel designs and implementations, and relevant regulatory challenges. The studies employ a wide range of methodologies and data sources, which we critically analyze and synthesize. Our analysis also reveals significant research gaps, including limited studies on security and privacy, underexplored stablecoins, unexamined failure cases, unstudied governance mechanisms, and the treatment of stablecoins under financial accounting standards, among other areas. |
