TOKYO: The dollar was on the defensive on Thursday after the Federal Reserve signalled it was ready to lower interest rates to combat growing global and domestic risks.

"Even though the market had anticipated much of what the Fed said, the dollar's fall was still a relatively large one," said Daisuke Karakama, chief market economist at Mizuho Bank.
"The main question is no longer if the Fed will cut rates in July, but whether the easing will be by 25 or 50 basis points."

Immediate focus for the yen was on the Bank of Japan's monetary policy decision due later on Thursday.
The BOJ is expected to keep its ultra-loose monetary policy unchanged but interest in markets will be on whether the Fed's dovish tilt would have any bearing on its Japanese counterpart.
