    Abstract: We study how survey-based measures of funding needs and availability influence the transmission of euro area monetary policy to investment. We first provide evidence that funding needs are primarily driven by fundamentals, while perceived funding availability captures financial conditions. Using these two measures, we assess how the effectiveness of monetary policy varies with fundamentals and financial conditions. Our results indicate that monetary policy is most effective when firms’ fundamentals are strong. In contrast, firms with favorable financial conditions exhibit a more muted investment response to monetary policy. By combining these two survey-based measures, we construct an indicator of financial constraints and show that financially constrained firms are more sensitive to monetary policy. These findings offer new light on the transmission of monetary policy to corporate investment, emphasizing not only the role of financial conditions, but also the importance of fundamentals, which are beyond the direct influence of central banks JEL Classification: C83, E22, E52

    Abstract: We examine what is widely considered to be one of the strongest channels of monetary policy transmission into household spending – the effect of changes in mortgage payments when mortgage rates are linked to the short-term policy rate. Using bank transactions data from Australia, we analyze a cumulative 425 basis point increase in the central bank policy rate, which caused mortgage repayments for homeowners with adjustable-rate mortgages to increase by $13, 800. We find little change in the spending of adjustable-rate mortgagors relative to fixed rate mortgagors. This is because adjustable-rate mortgages come with redraw facilities that make mortgages liquid, and households had large excess buffers due to pandemic-era transfer programs and restrictions on spending. Our findings demonstrate that the direct effects of a monetary policy tightening on household spending need not be large.

    Abstract: This paper explores the macroeconomic implications of lowering the inflation target in an Emerging Market such as South Africa using the IMF’s Global Integrated Monetary and Fiscal model (GIMF). Model-based simulations indicate that lowering the inflation target from 4.5 to 3 percent, as recently announced by South Africa’s central bank, may entail moderate near-term output costs (measured by the so-called “sacrifice ratio”), while leading to medium-term output gains and lower borrowing costs. The near-term costs critically depend on the credibility of the central bank, which determines the speed with which agents adjust their inflation expectations. Specifically, output costs are lower when inflation expectations adjust more rapidly following the announcement of the new target by the central bank. Similarly, higher sensitivity of risk premia to the announcement of a lower inflation target can further reduce these costs. Concurrent fiscal consolidation can help support the disinflation process and lower the marginal sacrifice ratio.

    Abstract: We provide empirical evidence on the impact of the Bank of Japan’s unconventional monetary policies on domestic economic variables and their spillovers to international sovereign yields. Using high-frequency asset price surprises to Bank of Japan (BOJ) policy announcements, we identify shocks to forward guidance (FG) and large-scale asset purchase (LSAP) policies. We show that expansionary LSAP and FG shocks increase Japanese activity and stock prices, lower unemployment, and depreciate the yen. We find that FG and LSAP shocks produce spillovers to sovereign bond yields in other countries. Spillovers from BOJ LSAP shocks seem to transmit through term premia, and the strength of spillovers is strongest to those markets where Japanese investors have a larger participation.

    Abstract: Is there an undesired side-effect of banking regulation on the non-bank sector? How effective is the non-bank transmission channel of monetary policy in the presence of macroprudential policy? Using a state-dependent local projection approach and a rich dataset capturing macroprudential tightening across euro area countries, we present strong cross-country heterogeneity. In financially conservative markets (Germany, France, the Netherlands), tight monetary policy combined with stricter macroprudential measures significantly contracts investment fund assets. Conversely, financial hubs (Luxembourg, Ireland, Italy) experience counterintuitive expansions under the same policy mix. We introduce a simple balance-sheet framework that shows how interacting funding-cost and collateral-constraint channels generate these opposing responses. Further disaggregation shows that equity funds are more vulnerable to joint tightening in conservative systems, while bond funds partly offset contractionary forces in hubs through higher yields.

    Abstract: South Africa’s experience developing a macroprudential role for its central bank could yield lessons for emerging market central banks. An explicit mandate to maintain and enhance financial stability accompanied a re-defined prudential and conduct regulatory (‘Twin Peaks’) framework in the Financial Sector Regulation Act of 2017. Using a macroprudential lens and international comparative analysis, this paper goes further than previous analyses (largely by legal scholars) and reveals weaknesses in the governance design for macroprudential policy. We suggest changes in the design of institutions, processes, transparency and accountability, to improve and future-proof SA macroprudential policymaking. These include: formalising the role of the central bank’s Financial Stability Committee - the de facto executive body for policy but not mentioned in the Act - preferably as a smaller statutory committee with external members and improved reportage; strengthening macroprudential policy in ‘ordinary’ times’ by adopting ‘comply or explain’ recommendations to reduce the Act’s crisis focus and better manage credit cycles; improved data collection to extend the macroprudential instrument toolbox for Borrower Based Measures and create early warning indicators for vulnerable households; and, for the Financial Stability Review, to address gaps in tracking and reporting risk indicators, and policy decisions, to better meet its new role as vehicle for transparency and accountability under the Act. We also consider political economic trade-offs between protecting the SA banking system and wider social and economic goals.

    Abstract: This paper serves as a reference guide on the effects of “standard” monetary policy shocks on output and prices, based on harmonised simulation exercises conducted across models of the European System of Central Banks (ESCB), meta-analysis of existing empirical literature for the euro area, and selected works on heterogeneity and non-linearities in the monetary transmission mechanism as captured by empirical models. Our analysis starts by comparing the effects of monetary policy shocks as estimated by structural, semi-structural and dynamic stochastic general equilibrium (DSGE) models, and identifying the main sources of heterogeneity – most notably via the specification of monetary policy rules, the slope of the Phillips curve, the role of real rigidities and financial frictions, and the expectations formation mechanism. While DSGE models tend to produce sharper responses, semi-structural models often reveal more gradual and persistent effects, in line with backward-looking empirical models. The second chapter presents a meta-analysis of estimated effects based on the empirical literature, which are broadly consistent with the results obtained from the ESCB models, although differences might appear when correcting for publication bias, or accounting for different identification frameworks. The study is then complemented by selected works on heterogeneity and non-linearities in the monetary transmission mechanism as captured by empirical models. Our analysis in the final chapter shows that monetary policy transmission is heterogeneous across countries, sectors, demand components, and time. It also reveals important non-linear and state-dependent dynamics: in high-inflation periods, greater price and wage flexibility amplifies the response of inflation while dampening output effects, thereby lowering the sacrifice ratio.

    Abstract: This paper assesses the global reach of US monetary policy over the 2007-2022 period in a sample of 78 countries and currency unions. Our findings show that the zero-lower-bound (ZLB) problem was restricted to advanced economies or those with currencies tied to the US dollar during the Global Financial Crisis (GFC) but became more widespread following the outbreak of COVID-19. The enormous and rapid expansion of the Fed’s balance sheet was not common elsewhere in the GFC period. Only three central banks expanded the size of their real balance sheet by more in relative terms than the Fed during the GFC and its aftermath. In contrast, six central banks did so after hitting the ZLB bound during the COVID-19 pandemic. The strongest support for a leading global role of Fed policy action comes from a pairwise assessment of central bank balance sheet changes during the two crises. Positive comovements, both contemporaneous and lagged, between US balance sheet changes and changes in other countries were common, with correlations being considerably more widespread and higher during the pandemic than the GFC.

    Abstract: This paper studies the effect of alternative monetary policy responses and the implementation of different fiscal policy measures to an inflationary shock in a monetary union, through the lens of a global DSGE model calibrated to the euro area. We find that a more aggressive monetary policy response mitigates the inflation surge, but has a detrimental impact on economic activity that imposes a stronger increase of public debt, reducing the fiscal policy space. We also find that some fiscal policy measures may alleviate the negative impact of the shock on households and firms, but do not significantly alter the inflation dynamics: a reduction of consumption taxes reduces inflation only temporarily, while an increase of transfers or of public investment slightly increase inflation initially, even if the latter may have a protracted negative impact. Overall, an appropriate mix of monetary and fiscal policies may be needed to ensure a swift return of inflation to target, while mitigating the impact on consumption. Targeting transfers to support constrained households has a mild impact on inflation, but may be a way to mitigate the impact on the most vulnerable with a less detrimental effect on public debt.

    Abstract: Imposing restrictions on policy rule coefficients in vector autoregressive (VAR) models enhances the identification of monetary policy shocks obtained with sign and narrative restrictions. Monte Carlo simulations and empirical analyses for the United States and the Euro area support this result. For the U.S., adding policy coefficient restrictions yields a larger and more precise short-run output response and more stable Phillips multiplier estimates. Heterogeneity in output responses reflects variation in systematic policy reactions to output. In the Euro area, policy coefficient restrictions sharpen the identification of corporate bond spread responses to monetary policy shocks.

    Abstract: Recent inflationary trends have reignited debates about the natural real interest rate (r∗). This paper reviews the literature on estimating r∗ and its drivers, highlighting significant uncertainty and variability in estimates. The challenges in achieving consensus on r∗ is mostly due to differing methodologies and model assumptions. Understanding these sources of uncertainty is essential for shaping future monetary policy, especially in a low interest rate environment where conventional policy tools may be limited.

    Abstract: This paper quantifies the “prediction value” of different forms of central bank communication. Combining traditional econometrics and natural language processing, we test how much forecast-improving information can be extracted from the different layers of the Federal Reserve communication. We find that committee-wise communication (statements and minutes) and speeches by the Chair and the Vice Chair improve interest rate forecasts, suggesting that they provide additional information to understand the policy reaction function. However, individual communication beyond the Vice Chair, such as speeches by board members, other FOMC members, and Federal Reserve Bank presidents not sitting in FOMC, is not forecast improving and sometimes even worsens interest-rate forecasts. Based on our theoretical model, we interpret these results as suggesting that the Fed may have overcommunicated, providing excessive noise-inducing communication for forecasting purposes.

    Abstract: This paper studies the issue of “should monetary policy lean against rational asset price bubbles†by establishing an analytically tractable New Keynesian model with endogenous capital accumulation. Rational bubbles may exist in equilibrium because of the extra liquidity they generate for financially constrained firms when a lumpy investment opportunity arrives. Under certain conditions, bounded bubble-driven fluctuations (in output) may emerge via both supply-side and demand-side mechanisms. The monetary policy analyses of the model do not strongly favor a leaning-against-the-bubble strategy and emphasize a special overreaction risk that it may suffer from relative to its conventional counterpart.

    Abstract: We develop a method to measure ambiguity—uncertainty about the distribution of out-comes—in asset markets, using the volatility of the empirical distribution of unpredictable components in transaction prices. For comparison, we measure risk as the volatility of the unpredictable price component itself, following the conventional practice of using the cross-sectional standard deviation. Applying this framework to 22 million secured lending transactions in the EU, we estimate ambiguity and risk perceived by major money market lenders. Unexpected monetary policy tightening raises both measures. Higher ambiguity reduces repo market liquidity by lowering loan volumes and increasing repo rates, thereby amplifying contractionary effects. Higher risk lowers loan volumes but also repo rates, partly dampening contractionary effects. Our results suggest that ambiguity plays a distinct and quantitatively important role in monetary policy transmission that is overlooked when fo-cusing on risk alone.

    Abstract: This paper investigates the effect of climate- and energy-related (green) communication by the European Central Bank (ECB) on the performance of renewable and fossil-based energy sectors. Using a sentence-embedding natural language processing method, we identify 247 ECB speeches from 2015 to 2024 that explicitly reference both climate and energy themes, categorize them, and compute a green score for each. The analysis reveals prominent topics of climate and financial risk, and monetary policy and economic conditions, along with consistently positive and trust-related emotional cues. We then use high-frequency identification to estimate the effect of ECB green speeches on the return differential between the green and the brown energy sectors. The results show that such ECB communication positively and significantly affects sectoral relative returns, highlighting the communicative role of the ECB in influencing the relative performance of green and brown energy sectors. The results remain robust across a series of sensitivity analyses. The effect does not change significantly with respect to the outbreak of the Russian–Ukrainian war or the ECB communication topics.

    Abstract: The 2010 sovereign crisis in the euro area brought to light the depth of the monetary union’s structural weaknesses. In particular, it highlighted the dangers of the sovereign-bank nexus – the amplification effect resulting from sovereign debt being held primarily by domestic banks. In response, important changes have been put in place. From a crisis management perspective, new institutions were created, such as the European Stability Mechanism which acts as a lender of last resort for euro area countries in difficulties. From an ex ante perspective, the crisis led to the launch of the banking union, which comprises the Single Resolution Mechanism – including the Single Resolution Fund – and the still-pending European Deposit Insurance Scheme. In addition, a wide array of regulation has been put in place, including Basel III and MREL/TLAC requirements to reduce the need for bailouts during financial crises and therefore limit the use of public funds in resolution processes. Despite this, the regulatory debate on how banking regulation should address this sovereign-bank interdependence continues today. In this paper we review the main regulatory proposals aimed at curtailing both exposure to sovereign risk and ownership concentration - two factors often associated to the broader sovereign-bank nexus. We assess their impact on bank capital and risk-weighted assets and simulate banks’ responses to these measures. We find that these solutions could entail significant side effects for both banks and bond markets, highlighting the importance of completing the monetary union and, in particular, issuing a European safe asset as key measures to mitigate this vulnerability.

    Abstract: In this paper we explore the role of the temporary and country-specific Additional Credit Claims (ACC) frameworks as a monetary policy implementation tool. We discuss their evolution and provide a novel and detailed description of all ACC measures adopted by the different euro area NCBs since 2012. Reviewing the literature, we document the channels through which ACCs contributed to liquidity distribution during the euro area sovereign debt crisis, the negative interest rate period and the pandemic. Drawing on panel data on the use of collateral and securities holding statistics, we document novel stylised facts about ACC mobilisation patterns during these episodes. A number of conceptual contributions and empirical findings emerge. While ACCs started out as a crisis instrument, the historical review highlights that ACCs constitute a policy tool that is suitable for enhancing monetary policy implementation. Empirically we find that pledging ACCs was not systematically associated with more concentrated collateral pools. Banks pledging ACCs were mostly universal banks and diversified lenders of varying size and were associated with higher funding costs for their short-term secured debt instruments, though the causality is unclear. Finally, drawing on the implementation and risk management experience with ACC frameworks as well as our empirical findings, we establish five lessons to inform future policy discussions on collateral JEL Classification: E4, E5, E65

    Abstract: Macroprudential policies are a key policy tool for financial regulators, but concerns persist that these policies restrict access to homeownership. I examine this concern using crosscountry data on homeownership for 28 countries. I find little evidence that macroprudential policies reduce homeownership rates in aggregate or for select groups such as low-income households. The estimates are precise enough to rule out large negative effects of macroprudential policies on homeownership rates. The null effects are consistent with models where credit shocks primarily affect prices rather than quantities. My results alleviate concerns that macroprudential policies systematically exclude certain households from ownership, but also indicate that relaxing such policies is unlikely to increase access to homeownership.

    Abstract: Monetary aggregates provide valuable information about the monetary policy transmission and the business cycle. This paper applies machine learning methods, namely Learning Vector Quantisation (LVQ) and its distinction-sensitive extension (DSLVQ), to identify turning points in euro area M1 and M3. We benchmark performance against the Bry–Boschan algorithm and standard classifiers. Our results show that LVQ detects M1 turning points with only a three-month delay, halving the six-month confirmation lag of Bry–Boschan dating. DSLVQ delivers comparable accuracy while offering interpretability: it assigns weights to the sources of broad money growth, showing that lending to households and firms, as well as Eurosystem asset purchases when present, are the main drivers of turning points in M3. The findings are robust across parameter choices, bootstrap designs, alternative performance metrics, and comparator models. These results demonstrate that machine learning can yield more timely and interpretable signals from monetary aggregates. For policymakers, this approach enhances the information set available for assessing near-term economic dynamics and understanding the transmission of monetary policy.

    Abstract: We document evidence of a U-shaped relationship between financial development and the adjustments of foreign exchange (FX) reserve holdings in response to a U.S. interest rate increase. Countries with intermediate levels of financial development sell reserves aggressively, while those with low or high development adjust little. Domestic interest rate responses are not systematically related to financial development. A model with borrowing constraints and foreign-currency debt rationalizes these findings: the associated pecuniary externality is maximized at intermediate levels of financial development. Calibrated to match the observed leverage and currency composition, the model reproduces the empirical U-shaped relationship under optimal FX reserve policy, and this relation is robust under a range of conventional interest-rate policy regimes.

    Abstract: By July 2025 the Federal Reserve confronted the most treacherous phase of post-pandemic disinflation—“the final mile” in which the last half-percentage-point of inflation proves harder to expunge than the first four. Headline PCE had fallen from 7 % in mid-2022 to 2.5 %, yet core services inflation, amplified by tariff-driven cost-push shocks and still-elevated wage growth, refused to converge to the 2% target. Meanwhile, payroll gains had slowed to a crawl (73 k in July), the unemployment rate had drifted up to 4.1%, and financial markets were pricing two 25 bp cuts before year-end. This paper reconstructs the FOMC’s July 29-30 deliberations—held against a backdrop of White House pressure, a flattening yield curve and an ongoing framework review—to show how the Committee balanced the competing risks of under-tightening (un-anchoring expectations) and over-tightening (precipitating a recession). Using the newly released minutes, high-frequency market data and a calibrated New-Keynesian model, we argue that the decision to hold the federal-funds target at 4.25-4.50 % can be interpreted as a state-contingent “flexible anchoring” strategy: keep policy moderately restrictive today while signalling that even a modest deterioration in labor-market momentum would justify insurance cuts as early as September. Counterfactual simulations indicate that the chosen path shaved 15 bp off the term premium, reduced the probability of a 2026 recession by one-third relative to a hawkish baseline, and kept 5y5y inflation expectations anchored at 2.05%. The episode illustrates how a transparently data-dependent reaction function can substitute for explicit forward guidance when the economy is buffeted by supply-side shocks whose persistence is unknown.

    Abstract: We develop a model framework that can be used to derive the forward-looking credit loss distributions for banks' credit exposures, to use it for (1) assessing the adequacy of provisions at the bank-portfolio level; (2) macro stress testing; and (3) informing the sufficiency of capital requirements, both from a micro- and macro-prudential perspective. The model is semi-structural and simulation-based, entailing a large number of simulated macro-financial scenarios instead of employing handpicked scenarios and ad-hoc scenario weights. The way the model-based credit loss distributions are generated can be made compatible with IFRS 9 or any other accounting regime. The model codes are made available online along with this paper.

    Abstract: We develop a New Keynesian framework to evaluate how potentially binding capacity constraints, and shocks to them, shape inflation. We show that binding constraints for domestic and foreign producers shift domestic and import price Phillips Curves up. Further, data on prices and quantities together identify whether constraints bind due to increased demand or reductions in capacity. Applying the model to interpret recent US data, we find that binding constraints in the goods sector explain half of the increase in inflation during 2021-2022. In particular, tight capacity served to amplify the impact of loose monetary policy in 2021, fueling the inflation takeoff.

    Abstract: This paper analyzes the impact of fiscal policy on inflation expectations across a large sample of advanced economies (AEs) and emerging market economies (EMs). We identify episodes of significant fiscal adjustment using both quantitative thresholds and a narrative approach and find that such episodes are associated with statistically significant changes in inflation expectations in EMs while the responses are muted in AEs. We also document that the relationship between fiscal policy and inflation expectations is more pronounced in high-inflation environments and under weak fiscal positions. Additionally, we explore how market perceptions of sovereign risk, as well as monetary and exchange rate frameworks, influence the transmission of fiscal policy to inflation expectations. Our empirical results suggest that it is especially important for EMs to implement prudent fiscal policy as it may help reduce inflationary pressures and inflation expectations.

    Abstract: We study heterogeneity in households’ credit across nine European countries (Belgium, Spain, Hungary, Ireland, Italy, Latvia, Lithuania, Portugal, and Slovakia) during 2022-2024 using granular credit register data. We first document substantial between- and within-country variation in mortgage and consumer lending by borrower age, loan maturity, and interest rate fixation. We then quantify the passthrough of the ECB’s recent tightening cycle to household borrowing costs, and assess its heterogeneous impact across households. Pass-through is nearly complete for mortgages (around 0.9) but considerably weaker for consumer credit (around 0.4). While mortgage pass-through is relatively homogeneous across countries, consumer credit shows pronounced cross-country differences that cannot be explained by borrower or loan characteristics. Younger households face stronger mortgage pass-through but weaker consumer credit pass-through relative to older borrowers, and longer maturities are associated with stronger pass-through in both credit markets.

    Abstract: The shock-absorbing capacity of Ghana’s inflation targeting (IT) policy has been under scrutiny, especially following COVID-induced inflationary pressures that drove real interest rates to a negative territory with implications for saving. This study examines IT policy’s role in moderating the real interest rate-saving nexus through the lens of the McKinnon-Shaw Hypothesis (MSH), from the perspective of private savings’ adaptation to real interest rate fluctuations. The study applies linear autoregressive distributed lag (ARDL) model to time series data spanning 1986-2023, augmented by non-linear ARDL analysis. We uncover no stable long-run relationship between real deposit interest rate and private financial saving as there prevails only a short run nexus. This finding suggests that the MSH might be delayed than implied by theory, which is likely due to asymmetric responses in the saving-interest rate nexus with positive and negative interest rates affecting saving differently. Results indicate a short run positive nexus between financial saving and negative real interest rate, while the relationship between positive real interest rate and saving is insignificant. IT policy, however, strengthens the relationship between saving and real interest rate over the long run, indicating that further strengthening of the policy could address asymmetric responses in the saving-interest rate nexus and help realize the MSH.

    Abstract: The post-pandemic rise in global inflation has renewed interest in the relative roles played by demand and supply factors in determining prices. Many central banks have stressed the joint role that persistent increases in input costs and excess demand played in boosting inflation in 2021 and 2022. Yet the latter influence plays no independent role in the workhorse New Keynesian models used by many central banks. Under the typical assumption of constant elasticity of substitution (CES) preferences, variations in consumption shift the firm’s profit function up and down, but do not influence its curvature. As a result, the optimal markup is not a function of demand. This assumption is contradicted by both evidence about household shopping behaviour and survey evidence about how firms set prices. This paper proposes an alternative structure based on non-homothetic household preferences over varieties of consumption goods. Specifically, the elasticity of substitution between goods is state dependent, declining during periods of strong per-capita consumption and vice versa. This captures the stylized fact that individual consumers are less price sensitive during economic booms and more price sensitive during downturns. These substitution effects in turn give the firm an incentive to adjust its markup in response to consumption demand. In aggregate, this generates desired markups that increase nonlinearly in consumption demand. When strategic complementarities in pricing are present, these preferences also give rise to state-dependent pass-through of cost shocks. A New Keynesian sticky price model featuring non-homothetic preferences is estimated on Canadian data, and strong evidence favouring a direct role for per-capita consumption demand is presented. This model is better able to capture the increase in core inflation that occurred in 2021–22, particularly when simulated in its nonlinear form.
