Interrelationships Between the Brazilian Financial Market and Foreign Financial Markets: New Evidence During and After the Subprime Crisis

This study analyzed the financial interrelations between Brazil and selected foreign economies (United States (US), Germany, United Kingdom (UK), Japan and China) during and after the Subprime crisis, using three financial market indicators: stock market index, exchange rate and interest rate. The Vector Autoregressive approach and the Granger causality test were used, with daily data. The periods considered were: i) period of crisis (03/14/2007 to 03/31/2010); and ii) post-crisis period (04/01/2010 to 12/30/2019). The results revealed that in the Subprime crisis, the interrelations were intense, especially in the stock and exchange markets. IBOVESPA and Brazilian exchange rate were predominantly affected by the US, German and UK equity markets. Evidence in the post-crisis period showed considerably lesser interrelationships between the Brazilian financial market and foreign financial markets. Thus, the results confirmed that the crisis significantly intensified interrelations, with the main contagion channels as the stock markets and the foreign exchange markets.
