BEIJING -- China markets breathed a sign of relief a day after the Federal Reserve pushed through a moderate 25 basis-point rate hike in the U.S.

The Fed's relatively measured comments helped allay fears that a too-rapid or intense tightening regime might further damage the market.

In tandem with other global bourses, the Hong Kong market began selling off in mid-May on fears that hawkish monetary policy would hurt equities. Between May 11 and Thursday's close, the Hang Seng index lost 7.4% of its value.

But on Friday the index popped up 2.5% to 16,268. It marked the second day of green, a shift given the recent gloom.

The Shanghai Composite Index added 0.04% to 1672.

The Fed's move could make it easier for China to follow up with its own monetary tightening, which many analysts have speculated may be in the offing given recent surges in lending and money supply.

"We think it will probably create more room for the Chinese central bank to raise interest rates," said Yiping Huang, Citigroup's chief economist for Asia in a phone interview. But he said the central bank will probably wait for second quarter GDP numbers, which are expected to come out in late July, before making any moves.
