This study examines the effects of unconventional monetary policies (UMPs) by the major central banks, namely the Bank of England (BOE), Bank of Japan (BOJ), European Central Bank (ECB) and the Federal Reserve (Fed) on the international financial markets, taking global spillovers into account. To this end, we apply the Global Vector Autoregressive (GVAR) model to 35 countries and one region for the period from March 2009 to July 2019. Our results indicate that the effects vary across four asset classes and central banks. For example, the UMPs of the Fed and the BOJ have signicant impacts on the regional sovereign bond markets, while the ECB UMPs show relatively stronger and broader effects on global bond markets. The global equity markets were also considerably affected by UMPs of the Fed, ECB, and BOJ. Furthermore, we found some evidence of monetary policy interactions amongst the four major central banks. This resulted in the effects being less persistent on the global bond markets for the Fed and the ECB, but more persistent on equity and foreign exchange markets for the Fed and the BOJ.
