NEW YORK (Reuters) - The dollar rose against a basket of currencies on Monday as U.S. President Donald Trump’s authorization of the use of an emergency crude stockpile in response to attacks on Saudi Arabian refining facilities cooled a surge in oil prices.
The Japanese yen and Swiss franc, both traditional safe-haven currencies, gave up much of their initial gains with a pullback in crude prices and anxiety about a disruption in global energy supply, analysts said.
Still, investors remained nervous about another attack, which underpinned demand for currencies of oil exporters such as Norway and Canada.
“Trump’s decision to offer up the strategic reserve to mitigate the fallout helped,” said Joe Manimbo, senior market analyst at Western Union Business Solutions in Washington. “The situation is still edgy on uncertainty over further attacks and possible retaliation.”
Oil prices had jumped about 20% in reaction to the drone strikes, which knocked out more than 5% of global oil output. Yemen’s Iran-aligned Houthi group claimed responsibility, but the United States has blamed Tehran.
On Sunday, Trump said he had authorized the release of oil from the U.S. Strategic Petroleum Reserve (SPR) if needed in a quantity to be determined. He also said Washington was “locked and loaded” to retaliate for the attacks on the Saudi facilities.
Another factor boosting the greenback was some exiting of bearish dollar bets in advance of the U.S. Federal Reserve’s two-day policy meeting. Traders widely expect the Fed will cut interest rates by a quarter of a percentage point this week.
In July, Fed policymakers lowered short-term rates for the first time since 2008.
“The market wants to short-cover in front of the Fed if the Fed doesn’t cooperate,” Schlossberg said.

On the other hand, speculators trimmed their bullish bets on the dollar, according to the latest data from the Commodity Futures Trading Commission.

Among currencies tied to oil-exporting countries, the Norwegian crown NOK=D3 strengthened to 8.9179 per dollar earlier before retreating to 8.9545, up 0.35% on the day.
The Canadian dollar CAD=D3 rose 0.35% to C$1.3243 after earlier reaching C$1.3208.
The Russian ruble RUB= was 0.41% higher.
Sterling, which has soared over the past week on growing investor confidence that a no-deal Brexit is off the table, fell back from a two-month high to $1.2426 GBP=D3, down 0.62%. It was little changed against the euro to 88.55 pence EURGBP=D3.
