The Central Bank raised interest rates by three-quarters of a percentage point (0.75 percent) on Wednesday. The Fed warned that tackling inflation will mean an increase of borrowing costs in a move that could signal it may be nearing a point of significant change in the progress of the economy.The move gives the central bank the option to increase rates by smaller increments in the future which would see an end to its three-quarter-of-a-percentage-point rises by December.This would then allow the Fed to implement a more preferable increase of half a percentage point for example.This would leave policymakers space to keep increasing interest rates if the rate of inflation does not begin to slow.In a news conference following the Central Bank’s latest policy meeting, Fed Chair Jerome Powell said he wanted to be clear that policymakers will be able to continue increasing rates.
