The U.S. dollar rebounded against major currencies on Wednesday on expectations that the Federal Reserve would signal rate hikes were on track, while the rouble recovered as buyers stepped in to pick up the Russian currency at cheaper levels.
Anticipation that the Fed would drop its use of the phrase "considerable time" to describe how long interest rates will stay near zero in its final policy statement of the year, due at 2 p.m. ET (1900 GMT), boosted the greenback.
Rate increases are expected to boost the greenback by driving investment flows into the United States.
Currencies
The dollar fell against the rouble, however, on the view that the Russian currency's collapse this year may have gone too far. While Brent crude still traded near 5-1/2-year lows below $60 a barrel, analysts said its free fall may be stabilizing.
Tumbling oil prices threaten Russia's economy since sales of oil and gas are Russia's chief source of export revenue.
The dollar was last down 9.7 percent against the rouble to trade at 61.66 roubles.

The euro was last down 0.8 percent against the dollar at $1.2407. The dollar was up 0.8 percent against the Swiss franc at 0.9677 franc, and gained 0.77 percent against the yen at 117.30 yen.
