* Oil hovers below $137

SINGAPORE, June 25 (Reuters) - Asian shares drifted lower and government bonds gained on Wednesday after a drop in U.S. consumer confidence and home prices hit the dollar and equities and underscored concerns about the world economy.
The dollar steadied after its drop overnight, gold inched down and oil hovered below $137 a barrel in slack trade ahead of the U.S. Federal Reserve's interest rate decision later.
The Fed is widely expected to keep its benchmark interest rate unchanged at 2 percent, ending a string of cuts aimed at blunting the economic impact of the mortgage credit market meltdown.
But markets eagerly wait for the central bank's statement, worried that weak economy gives the Fed little wiggle room to deal with inflation fuelled by record-high oil prices.
"There's a real concern about global inflation at the moment, and you've still got the lingering crisis, so it's going to be tough for equities," said Greg Goodsell, an equity strategist at ABN AMRO in Australia.
Tuesday's data underscored the Fed's dilemma, showing a drop in U.S. consumer confidence to a 16-year low and a further decline in home prices, both heralding a drop in U.S. consumer spending.[
]A sluggish U.S. economy and a weak dollar are bad news for Asia, which relies heavily on exports as an engine of economic growth and a source of corporate profits.
Tokyo's Nikkei average <
> fell 1.5 percent by the midday break, its fifth day of losses, with exporters such as Toyota Motor Corp <7203.T> hit by weak outlook for its key U.S. market.The MSCI index of Asian stocks outside of Japan <.MIAPJ0000PUS> was down 0.3 percent by 0310 GMT.
Hong Kong stock market did not open as usual on Wednesday after tropical storm Fengshen struck the territory, wreaking havoc in the wealthy city of 7 million. There were no reports of casualties and the shut-down had no impact on markets elsewhere in the region. The market may open for the afternoon session if the cyclone alert gets lifted before noon.
Oil prices <CLc1> pulled back slightly in morning trade after concerns over Nigerian supply disruptions, tensions between Israel and Iran drove it more than $1 higher on Tuesday. But prices still hovered around $3 below all-time high, underpinned by supply concerns, Middle East tensions and expectations of a drop in U.S. crude stocks.
The weak U.S. growth outlook and stock market declines lifted safe-haven government bonds, with the yield on the Japanese benchmark 10-year bond <JP10YTN=JBTC> dipping 2 basis points and touching a one-month low.
"Tuesday's release showed that the deterioration in U.S. consumer indicators took a turn for the worse," said Naomi Hasegawa, a senior fixed-income strategist at Mitsubishi UFJ Securities. "It is leading to expectations that the Fed may not hike at all," she said.
The dollar was little changed after it slipped 0.25 percent against a basket of major currencies on Tuesday. It traded at 107.77 yen <JPY=> and the euro was little changed at around $1.5570 <EUR=>.
Gold <XAU=>, which tends to benefit from the dollar's weakness and inflation fears, eased on Wednesday as investors booked profits from a recent rally and squared positions ahead of the Fed rate decision.
