The expansion of money, given an increase in the monetary base, is inevitable, and will ultimately result in higher inflation and interest rates. In shorter time frames, the expansion of money can also result in higher stock prices, a weaker currency, and increases in commodity prices such as oil and gold.

It's difficult to estimate the magnitude of the inflationary and interest-rate consequences of the Fed's actions because, frankly, we haven't ever seen anything like this in the U.S. To date what's happened is potentially far more inflationary than were the monetary policies of the 1970s, when the prime interest rate peaked at 21.5% and inflation peaked in the low double digits.
