While a selloff of long-term U.S. Treasurys eased, analysts said the U.S. bond market remains vulnerable to selling pressure, which could lead to higher yields and more dollar-buying.

Early Tuesday, the dollar was at Yen110.81 yen, compared with Yen110.84 late Monday in New York.

Any lasting impact from the earthquake on the foreign-exchange market is expected to be minimal, said Koji Fukaya, chief executive of FPG Securities in Tokyo.

The dollar's decline was likely also driven by Japanese exporters who had been waiting for an opportune momentto sell dollars, Fukaya said. Profit-taking on the dollar's recent gains emerged ahead of a public holiday Wednesday in Japan, and the U.S. Thanksgiving holiday on Thursday, he said.

(, U.S. President-elect Donald Trump outlined his plans for his first 100 days in office (, including formally declaring his intent to withdraw from the Trans-Pacific Partnership (TPP) trade deal and replace it with bilateral agreements.

"Even though this had no immediate market reaction, it eased [dollar] gains a bit, as it [tears up] any hopes for a softer protectionist stance on international trade," said Pissouros.
