TOKYO (Reuters) - Asian shares were treading water in early trade on Wednesday as crude oil futures steadied after a selloff, while a widely expected interest rate hike from the Federal Reserve underpinned the dollar.

MSCI’s broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was a few ticks higher in early trade.

Japan's Nikkei stock index .N225 edged down slightly, shrugging off data that showed Japanese core machinery orders rose a more-than-expected 5 percent in October in a sign of resilient capital spending.

On Wall Street on Tuesday, the Dow Jones Industrial Average .DJI and the S&P 500 .SPX both notched record closing highs, though the Nasdaq Composite .IXIC shed 0.19 percent. [.N]

The dollar index, which tracks the greenback against a basket of six major rival currencies, edged down 0.1 percent to 94.048 .DXY but remained not far from three-week highs touched on Tuesday.

The dollar was steady against the yen at 113.51 JPY=, while the euro was also steady at $1.1743 EUR=.

Bitcoin was up 1.2 percent on the Bitstamp exchange at $16,851 BTC=BTSP.

The Fed’s two-day policy meeting will conclude later on Wednesday. The U.S. central bank is seen raising its benchmark rate to between 1.25 and 1.50 percent, with investors also focusing on clues to the pace of tightening next year as inflation remains cool.

Those decisions may be influenced by news on Tuesday that U.S. wholesale inflation rose last month. Consumer price index (CPI) data will be released later in the global session on Wednesday.

Also on investors’ radar screens was the outcome of an Alabama’s Senate election, where Republican candidate Roy Moore, endorsed by U.S. President Donald Trump, faced off against Democratic challenger Doug Jones.

“The election itself won’t have a direct impact on currencies, but a victory for Moore is seen as making it easier for the administration to pass legislation,” including tax reform, said Mitsuo Imaizumi, Tokyo-based chief foreign-exchange strategist for Daiwa Securities.

“In the meantime, it’s hard to sell the dollar ahead of the Fed, although we might see ‘buy-the-rumour-sell-the-fact’ after the actual announcement,” as investors lock in their gains, Imaizumi said.

Crude oil futures steadied after facing profit-taking pressure when they surged to two-year highs in the previous session on an unplanned closure of the pipeline that carries the largest volume of North Sea crude oil. [O/R]

Brent crude LCOc1 was yet to trade in Asia after shedding 2 percent on Tuesday. U.S. crude CLc1 added 0.6 percent, or 32 cents, to $57.46, after slipping 1.4 percent overnight.
