NEW YORK (Reuters) – The dollar continued to power higher on Friday, pressuring stocks and commodities, on expectations of a Federal Reserve interest rate hike in contrast to easing monetary policy actions by most other major central banks.

The dollar index .DXY was on track for a back-to-back weekly gain of more than 2 percent, setting up its strongest two-week performance in almost five years.

Stocks fell on Wall Street, with the S&P 500 set to fall for a third straight week. The index is about 3 percent below its record high set this month. Energy shares weighed on it the most as crude prices fell near six-year lows plumbed in late January.

“As (oil) keeps falling there are bigger concerns that we could see problems with respect to capital expenditures and employment in certain regions of the (United States),” said Michael Arone, chief investment strategist for State Street Global Advisors’ U.S. Intermediary Business in Boston.

The Dow Jones industrial average .DJI fell 183.64 points, or 1.03 percent, to 17,711.58, the S&P 500 .SPX lost 17.15 points, or 0.83 percent, to 2,048.8 and the Nasdaq Composite .IXIC dropped 30.21 points, or 0.62 percent, to 4,863.08.

The MSCI All-Country World equity index .MIWD00000PUS was down 0.8 percent and emerging-markets stocks .MSCIEF fell 1 percent. The FTSEurofirst 300 pan-European index .FTEU3 was down 0.1 percent.

Stocks in Europe continued to be supported by the European Central Bank’s bond-buying plan, which kept euro zone yields near record lows.

Investors hope a meeting of Fed policy-makers on March 17 and 18 will yield clues about the timing of a rate increase.

The divergence in monetary policy pushed the euro EUR= lower against the greenback, briefly testing Thursday’s 12-year low below $ 1.05. It was last down 1.1 percent at $ 1.0519.

The Mexican peso MXN= weakened versus the dollar after a two-day respite, trading within 1 percent of its record low hit on Wednesday.

“What we see is a dollar move, massive dollar buying from real money as well as hedge funds. It’s being bought all across the board versus all currencies and those relying heavily on short-term inflows are being hit the hardest,” said Bernd Berg, strategist at Societe Generale in London.

The dollar index .DXY added 0.6 percent to 100.06.

U.S. crude CLc1 fell 3.6 percent to $ 45.36 per barrel, while Brent crude LCOc1 fell 1.4 percent to $ 56.26. The global oil glut is getting bigger and U.S. production shows no sign of slowing, the International Energy Agency said.

The U.S. benchmark 10-year Treasury note yield US10YT=RR edged up to 2.0998 percent from Thursday’s 2.096 percent, reflecting a price decrease of 1/32.

Spot gold XAU= was little changed near $ 1,154 an ounce, following nine consecutive sessions of declines. Copper CMCU3 dipped 0.4 percent but was on track to finish the week with a 1.5 percent gain.
