May 16 (Bloomberg) -- The world's most powerful central banks are telegraphing the end of interest-rate cuts, and traders already anticipate the first steps in the opposite direction. Federal Reserve officials this week flagged inflation risks after slashing borrowing costs seven times since September and Bank of England Governor Mervyn King unveiled Britain's worst price outlook in a decade. Faster growth is vindicating European Central Bank President Jean-Claude Trichet's refusal to cut rates in response to the credit crisis. ``The central banks are taking a pause, but that could turn into a permanent end to rate cuts,'' said Thomas Mayer, co-chief economist at Deutsche Bank AG in London. ``The risk we won't see more cuts from the Fed and Bank of England has grown, and markets have pushed out expectations of ECB easing.'' The danger is that food and oil prices are rising so fast that inflation will replace costlier credit as the chief threat to the global economy. That may force the Fed to turn a deaf ear to what King labels the ``siren'' calls for rate cuts and perhaps consider raising them instead. Fed Chairman Ben S. Bernanke, 54, and his team reduced their benchmark rate by 3.25 percentage points to 2 percent. The Bank of England has cut its main rate three times to 5 percent and Canada's central bank has moved on four occasions to 3 percent. Now, Merrill Lynch & Co. forecasts global inflation will accelerate to 4.7 percent this year, the fastest pace since 1999, from 3.4 percent in 2007.
