The safe-haven yen was pinned near its weakest levels for months on Tuesday while riskier currencies were firm against the dollar, as traders waited to see whether U.S. lawmakers could secure an end to the government shutdown in coming days.
The euro was steady at $1.1558 and sterling has been creeping higher to $1.3177.
A deal that would restore U.S. federal funding, and end the longest shutdown on record, cleared an initial Senate hurdle late on Sunday, though it was unclear when Congress would give its final approval.
A gain of about 0.7% for the Australian dollar to $0.6536 and a drop in the yen to 154.11 per dollar were the biggest movers in the wake of the breakthrough. A break of 154.48 would take the yen to its weakest in nine months.
Analysts said their moves could be vulnerable to reversal if the path to inking the shutdown deal dragged much beyond this week. There are still several Senate hurdles to clear.
House of Representatives Speaker Mike Johnson said his chamber could pass the bill as soon as Wednesday and send it on to President Donald Trump to sign into law, if the Senate acts quickly.
"Reopening by November 15 is just about fully priced in for now, so any deviation or delays from that could be viewed as risky for this rebound in liquidity," said Brent Donnelly, president at analytics firm Spectra Markets.
New Zealand inflation expectations, British weekly wage data and Germany's ZEW sentiment survey are due later in the session.
The New Zealand dollar has been under pressure for months as the economy slows and had on Tuesday hit a 12-year low against the Australian dollar, reflecting a divergent outlook for interest rates in the Antipodes.
