In the fight against high inflation, the US Federal Reserve is raising interest rates more than it has been since 1994.
It decided on Wednesday to raise the rate by 0.75 points to the new range of 1.50 to 1.75 percent.

Analysts, on the other hand, had expected a slight weakening.
In the run-up to the Fed's interest rate decision, stock prices on the US markets had risen.
After five consecutive trading days of losses, the Dow Jones Industrial rose 1.26 percent to 30,747 points in early trading.
