Summary of the CROSS-COUNTRY REPORT ON SPILLOVERS

Core Content

This report examines the spillover effects of unconventional monetary policies (UMPs) from the European Central Bank (ECB) and the U.S. Federal Reserve (Fed) on selected European countries: the Czech Republic, Denmark, Hungary, Poland, and Sweden. It employs three analytical approaches—event study, country-level VAR (Vector Auto Regression), and global VAR (Vector Auto Regression)—to assess the financial and macroeconomic impacts of these policies.

Main Points

A. Introduction

• Central banks implemented UMPs post-2008 financial crisis to stimulate growth and inflation.
• The ECB introduced various UMPs, including the Asset Purchase Programme (APP), which is more substantial than earlier measures.
• UMPs are expected to benefit neighboring countries, but may also cause financial volatility.
• The IMF supports ECB's UMP to achieve price stability and aid European recovery.
• Spillovers may affect public sector debt, exchange rates, equity returns, and capital flows.

B. Recent Developments and Stylized Facts

• Government Bond Yields: Declined significantly following ECB UMP announcements, with larger effects in emerging markets.
• Exchange Rates: Appreciated against the euro, especially in countries with strong trade and financial linkages.
• Capital Flows: Increased in Poland and the Czech Republic, but not in other countries.
• Equity Returns: Reacted positively to ECB UMP announcements, especially in Sweden and Denmark.
• Factors Influencing Spillovers: Domestic policy responses, market expectations, and global financial conditions played a role.

C. An Event Study Approach

• The event study focuses on the immediate financial spillovers from ECB UMP announcements.
• It uses OLS regression to estimate the impact on 10-year bond yields, exchange rates, equity returns, and mutual fund flows.
• The analysis considers both direct and indirect impacts, with the indirect impact stemming from reduced financial volatility.
• The APP had stronger spillover effects than earlier UMPs, but these were partially offset by expectations of tighter U.S. monetary policy.

D. A Country-Level VAR Analysis

• A VAR model is used to evaluate the nature and scale of spillovers from ECB UMP to Denmark, Poland, and Sweden.
• The model includes both endogenous and exogenous variables, with the ECB UMP as an exogenous shock.
• The endogenous variables include domestic policy rates, exchange rates, inflation, and GDP.
• The analysis covers the period from 2002 to 2015, including both conventional and unconventional monetary policy regimes.
• The results suggest that while UMPs have immediate effects on exchange rates, real economic effects are less consistent and inflation remains largely unaffected.

Key Findings

• Financial Spillovers: ECB UMP led to lower bond yields in all five countries, with more pronounced effects in emerging markets.
• Exchange Rate Appreciation: Exchange rates appreciated against the euro, with the Polish zloty and Hungarian forint showing the most significant movements.
• Capital Flows: Increased in some countries, particularly Poland and the Czech Republic, but not in others.
• Equity Markets: Showed positive responses to ECB UMP announcements, especially in Sweden and Denmark.
• APP Impact: The ongoing APP had a stronger financial impact than earlier ECB UMPs, but this was counteracted by U.S. monetary policy expectations.
• Policy Implications: The spillover effects are influenced by domestic policy responses and global market conditions. Policymakers should be aware of these spillovers and consider their implications for financial stability and economic growth.

Conclusion and Policy Implications

• The spillovers from ECB UMP have been significant, especially in financial markets.
• The effects are more pronounced in countries with stronger trade and financial ties to the euro area.
• The event study and VAR analysis highlight the need for careful monitoring of spillovers and their potential impact on domestic economic conditions.
• The report underscores the importance of understanding how external monetary policies affect local economies and the necessity for coordinated policy responses to mitigate unintended consequences.

Key Variables and Data

• Financial Variables: Bond yields, exchange rates, equity returns, and capital flows.
• Macroeconomic Variables: GDP, inflation, and policy rates.
• Time Frame: January 2002 to October 2015.
• Methodology: Event study and VAR models were used to isolate the effects of ECB UMP from other factors.
