The U.S. dollar fell slightly on Tuesday as receding fears of a full-blown banking crisis slowed demand for so-called safe haven assets.
The yen rallied, despite traditionally also being a safe haven, with analysts pointing to a pick-up in flows ahead of the end of Japan's fiscal year on Friday.
The dollar fell as low as 130.51 yen , and was last off 0.41% at 130.98 as the Japanese currency rose. That undid some of the dollar's 0.64% jump against the yen in the previous session, which tracked a large rise U.S. government bond yields.
Analysts said Japanese companies were likely to be selling foreign bonds to bolster their balance sheets.
"The time of the year - the Japanese fiscal end - I think there are some flows from Japanese repatriating," said Bart Wakabayashi, branch manager at State Street in Tokyo.
"If that's it, it's pretty much a one-off, and then we'll get back to basics, which is essentially following yields."
Elsewhere, the euro and pound rose as markets took solace from First Citizens BancShares' agreement to buy all of failed lender Silicon Valley Bank's deposits and loans, and the fact that no further cracks have emerged in global banking.
The euro was last up 0.26% to $1.083. Sterling climbed 0.2% to $1.231, just below a two-month high.
"Markets are just generally a little bit risk-positive … and the default position against that background is that the dollar drifts lower," said Adam Cole, chief currency strategist at RBC Capital Markets.
"We could be in this kind of risk-on, risk-off environment for a couple of months," Cole added.
The U.S. dollar index - which gauges the currency against six peers, including the yen - fell 0.15% to 102.6, after a 0.26% drop on Monday.
The company and its founder have been sued by the U.S. Commodity Futures Trading Commission (CFTC). The exchange also suffered a technical glitch on Monday that forced it to temporarily suspend some operations.
The risk-sensitive Australian dollar rose, getting an additional boost from better-than-expected retail sales data. It was last up 0.35% to $0.667 .
Simon Harvey, head of FX analysis at Monex Europe, said a U.S. Senate hearing with top bank regulators later in the day could cause some volatility.
"Officials still hold an information advantage on the state of the banking sector," Harvey said.
