Macroprudential Policy and Income Inequality: The Trade-off Between Crisis Prevention and Credit Redistribution
by Simona Malovaná, Jan Janků and Martin Hodula

We estimate the impact of macroprudential policy on income inequality using a broad panel of 105 countries. The empirical results show that macroprudential policy can affect income inequality in both directions, with the direction of effect depending on the type of tool used and the wider macrofinancial conditions. The results suggest that timely implementation of macroprudential policy can contribute to a more even distribution of income in society, thanks to the increased resilience of the financial sector to financial crises.

The Application of Multiple-Output Quantile Regression on the US Financial Cycle
by Michal Franta

The paper demonstrates the benefits of multiple-output quantile regression for macroeconomic analysis. The domestic financial cycle, which is characterized by the co-movement of credit and property prices, is a natural subject of such methodology. The analysis finds that the crucial indicators include the banking sector’s exposure to household credit, household leverage, house price misalignment and financial market volatility. This contrasts with the negligible role of real-economy factors.

Finding the Optimal Currency Composition of Foreign Exchange Reserves with a Quantum Computer
by Martin Veselý

In this paper, we focus on applications of quantum algorithms to dynamic portfolio optimization based on the Markowitz model. In particular, we compare algorithms for universal gate-based quantum computers (the QAOA, the VQE and Grover adaptive search), single-purpose quantum annealers, the classical exact branch and bound solver and classical heuristic algorithms (simulated annealing and genetic optimization). We demonstrate portfolio optimization on finding the optimal currency composition of the CNB’s FX reserves.

by Soňa Benecká and Petr Polák

Do the Breadth and Intensity of the Tightening of Monetary Conditions Affect their Impact on the Global Economy?
by Soňa Benecká, Martin Kábrt, Luboš Komárek and Petr Polák

This article examines the potential spillover effects of one of the most broad-based and rapid episodes of the tightening of global monetary conditions in history, which occurred in 2022 and 2021. In the article, the authors focus on the exchange rate channel, which is zero-sum in global terms, and the limited transmission speed. They also examine the resulting challenges for central banks.

Relationship Between the MREL and Macroprudential Capital Buffers
by Lukáš Pfeifer and Libor Holub

This article studies the impacts of the minimum requirement for own funds and eligible liabilities (MREL) on the effectiveness of macroprudential capital regulation of the banking sector. It examines the MREL's effect on the usability of banks' capital buffers and any capital surplus for absorbing losses and lending to the economy in various economic scenarios. The article concludes that the introduction of the MREL may cause usability to decrease, especially during long adverse economic episodes in banks that use internal models to manage credit risk.

Monetary Policy in the Midst of War: The Case of Ukraine
by Vojtěch Molnár

Ukraine has been plagued by war for over a year. Given the situation, most attention is understandably focused on matters other than monetary policy. That said, the central bank is playing a major role in ensuring at least the basic functioning of society and the economy in wartime conditions. This article first summarises the monetary policy regime operated by the National Bank of Ukraine (NBU) before the war. It then looks at the approach taken by the NBU since the war broke out in February last year.

The Current Monetary Conditions in the Czech Republic: Tight or Easy?
by Jan Frait and Jakub Matějů

Monetary policy is more than just interest rates: the effect of the exchange rate is also important. Therefore, the real monetary conditions index is commonly used for small open economies, including the Czech economy. This combines the effect of both the interest rate component and the exchange rate component of monetary conditions and shows how tight or easy the overall monetary policy stance is. This blog article explains what this index says about monetary policy in the Czech Republic.
