From purchases to exit: central bank interventions in corporate debt markets

05/13/2025 European Central Bank Central banks

Central banks increasingly act as market-makers-of-last-resort, yet the impact and exit of such interventions remain poorly understood. Using euro-area data, we analyze the cycle of market freeze, intervention, and exit in short-term debt markets. A run on money market funds (MMFs) triggered a collapse in these markets in March 2020. Firms replaced only 27% of lost funding through credit lines. The European Central Bank intervened, fully replacing MMFs for some firms and allowing them to issue more debt at lower rates and longer maturities.

Rational inattention during an RCT

05/12/2025 European Central Bank Central banks

We introduce an information provision experiment into a standard dynamic rational inattention model. We derive analytical results about how the treatment effect varies with characteristics of the environment and the individual. We use these results to discuss findings in the empirical literature on information provision experiments that can be explained by rational inattention of survey respondents and what this interpretation implies about behavior outside the survey.

Bank lending rates and the riskiness of euro area household loans

05/08/2025 European Central Bank Central banks

I assess the impact of the recent hike in bank lending rates on euro area retail borrowers using a novel microsimulation framework that updates household-level data of a recent representative survey with up-to-date macro-financial information. The key novelty is that existing mortgages are gradually repaid, and new ones are extended, a feature necessary for medium-term simulations in a period of sizable credit growth. Since lending rates have increased, debt servicing has become more demanding, and the simulated share of distressed loans has increased.

Beware of large shocks! A non-parametric structural inflation model

05/06/2025 European Central Bank Central banks

We propose a novel empirical structural inflation model that captures non-linear shock transmission using a Bayesian machine learning framework that combines VARs with non-linear structural factor models. Unlike traditional linear models, our approach allows for non-linear effects at all impulse response horizons. Identification is achieved via sign, zero, and magnitude restrictions within the factor model. Applying our method to euro area energy shocks, we find that inflation reacts disproportionately to large shocks, while small shocks trigger no significant response.

Why monetary policy should crack down harder during high inflation

04/29/2025 European Central Bank Central banks

The recent surge in inflation has led to a significant increase in the frequency of price changes, making prices more flexible. Conventional models assume a constant price change frequency, but in state-dependent models the frequency varies with economic conditions. Price flexibility has an impact on the effectiveness of monetary policy. In high inflation periods, frequent price changes make monetary policy more effective in reducing inflation with less impact on economic activity. Therefore, monetary policy should be more aggressive during such periods to stabilise prices efficiently.

Mortgage refinancing and the marginal propensity to consume

04/24/2025 European Central Bank Central banks

This paper investigates the role of mortgage refinancing in shaping the estimates of marginal propensity to consume (MPC) and its implications for fiscal policy. Using U.S. household data, we find that MPCs decrease during the year of mortgage refinancing and stabilize afterwards, particularly among households with lower liquid assets, higher debtto-income ratios, and valuable illiquid assets. The empirical evidence suggests that refinancing provides extra liquidity, reducing MPCs.

Do central bank reforms lead to more monetary discipline?

04/09/2025 European Central Bank Central banks

This paper investigates the impact of reforms altering legal central bank independence (CBI) on monetary policy discipline and credibility, two key mechanisms shaping price stability. Using a sample of 155 countries over more than 50 years (1972–2023), we show that reforms improving CBI strengthen monetary discipline and the credibility of central banks. Larger reforms enhance monetary discipline with a lag, achieving their full effect after ten years. Central bank reforms have a greater impact on monetary discipline in countries that have not reversed earlier reforms.

Interest rate control and the transmission of monetary policy

04/02/2025 European Central Bank Central banks

We study how short-term interest rate volatility affects the transmission of monetary policy. To identify exogenous changes in volatility, we exploit the pronounced heteroskedasticity visible in the time-series of euro area short-term rates over the past two and a half decades. Interacting the exogenous variation in volatility with high-frequency-identified monetary policy shocks, we find that increases in volatility dampen the effects of monetary policy on output and prices.

Word2Prices: embedding central bank communications for inflation prediction

04/01/2025 European Central Bank Central banks

Word embeddings are vectors of real numbers associated with words, designed to capture semantic and syntactic similarity between the words in a corpus of text. We estimate the word embeddings of the European Central Bank’s introductory statements at monetary policy press conferences by using a simple natural language processing model (Word2Vec), only based on the information and model parameters available as of each press conference. We show that a measure based on such embeddings contributes to improve core inflation forecasts multiple quarters ahead.

Effects of monetary policy on labor income: the role of the employer

03/31/2025 European Central Bank Central banks

This paper investigates the role of firms in the transmission of monetary policy to individual labor market outcomes, both the intensive and extensive margins. Using German matched employer-employee administrative data, we study the effects of monetary policy shocks on individual employment and labor income conditioning on the firm characteristics. First, we find that the employment of workers in young firms are especially sensitive to monetary policy shocks.
