Hybrid car Interest rates have a very important impact on the exchange rate, which is the most important factor affecting the exchange rate. We know that the exchange rate is the relative price between the two countries' currencies. Like other commodity pricing mechanisms, it is determined by the supply and demand relationship in the foreign exchange market. Foreign exchange is a kind of financial asset, which people hold because it can bring the benefits of capital. Dave Rosenberg, chief economist at Gluskin Sheff, said there was no real breakthrough in the bond market, and that current interest rate yields did not significantly break the mean and median levels since 2009.
