USD Federal Open Market Committee Rate Decision
The Board of Governors of the Federal Reserve announces an interest rate.
This interest rate affects the whole range of interest rates set by commercial banks, building societies and other institutions for their own savers and borrowers.
It also tends to affect the exchange rate.
Generally speaking, if the Fed is hawkish about the inflationary outlook of the economy and rises the interest rates it is positive, or bullish, for the USD.
