How Do Central Bank Announcements Affect Stock Market Volatility? A Quantitative Event Study

| Abstract | This paper investigates whether monetary-policy announcements trigger short-term stock-market volatility and whether the magnitude of that reaction differs between advanced and emerging economies. Using daily data for the S&P 500 (United States), EURO STOXX 50 (euro area) and Nifty 50 (India) from January 2015 to December 2024, we estimate two complementary measures of volatility: (i) the standard deviation of log-returns in a symmetric [−1,+1] trading-day event window and (ii) conditional variances from GARCH(1,1) models. Announcements by the Federal Reserve, European Central Bank (ECB) and Reserve Bank of India (RBI) are classified as “expected” or “unexpected” using Bloomberg survey medians. We find that unexpected policy actions raise same-day conditional variance by 23 % in the United States, 17 % in the euro area and 34 % in India, relative to a 30-day pre-event baseline. Cross-sectional regressions suggest that higher announcement-day volatility in India is associated with greater macro-uncertainty and lower central-bank credibility. The results imply that clear forward guidance can mitigate short-lived bouts of volatility, particularly in emerging markets. |
