There are times when a market such as housing, transportation or the stock or mortgage market keep rising and people with capital want to join in this growth. Soon the markets become overheated, partly because of the abundance of investment money and speculation. This is when the government should raise interest rates and increase the cost of borrowed money. Governments are shy about doing this because it could cause the very recession. Yet this is the best time to do this so that the inevitable recession never reaches the magnitude of the recent Great Recession.
