The dollar rose on Monday along with the yen and the Swiss franc as investors rushed into safe-haven assets amid fears that Russia is preparing to invade Ukraine.
The move came a day after the United States said Russia could attack Ukraine at any time. Russia has denied having any such plans though a senior official said it was ready to fire on foreign ships and submarines that illegally enter its waters.
The dollar index rose 0.4 percent to 96.351, its highest since Feb. 1, at 1133 GMT.
Euro-dollar one-month implied volatility was at 7.45 percent, the highest since November 2020, from below 6 percent at the end of January.
The rouble was flat at 77.08 against the dollar, after tumbling to its lowest since Jan. 28 on Friday as investors ditched Russian assets.

The euro weakened on Friday when a rush into safe-haven assets overshadowed expectations for monetary policy tightening from the European Central Bank.
ECB president Christine Lagarde had also dampened some of the bullish euro sentiment by reiterating that any policy action will be gradual.
The U.S. Federal Reserve will release its January meeting minutes on Wednesday, but analysts said central bank action was unlikely to return to the spotlight until the risk of an escalation over Ukraine recedes.
The rush into safe-haven assets has boosted the Japanese yen since Friday, while the Bank of Japan successfully defended its key bond yield target on Monday, holding the line on its ultra-loose monetary policy.
The yen strengthened 0.3 percent to 115.16 against the dollar, and 0.6 percent versus the euro.
“These two currencies (the U.S. dollar and the yen)—as well as the Swiss franc—should remain bid until, and if, we get indications that a diplomatic solution is in sight,” ING analysts said, adding that “markets are adopting a wait-and-see approach on geopolitics at the start of the new week.”
We “flag quite significant downside risks for exposed currencies—directly the rouble and indirectly all pro-cyclical currencies and especially the European ones—should tension escalate further,” ING added.
The Swiss franc rose 0.5 percent against the euro to 1.0451, its highest since Feb. 3.
