The dollar fell for a second day on Thursday after a rare warning by the finance chiefs of the United States, Japan and Korea over the sharp decline in other currencies, which in turn offered the yen some rare respite.
The yen got a modest lift after Japan's top currency diplomat Masato Kanda said finance leaders of the G7 reaffirmed their stance that excessive currency volatility was undesirable.
Strong U.S. economic data and persistent inflation have prompted investors to drastically rethink the chances of the Federal Reserve cutting rates any time soon. Tensions in the Middle East have also added to the dollar's safe-haven appeal.
The upshot has been other currencies, particularly in Asia, have been battered. The yen has been pinned near 34-year lows, which has prompted several warnings from Japanese authorities as traders fret about possible intervention.
The U.S., Japan and South Korea agreed to "consult closely" on foreign exchange markets in their first trilateral finance dialogue on Wednesday, in a nod to concerns from Tokyo and Seoul over their currencies' recent sharp declines.
"It sends another strong signal to market participants that Japan and Korea are moving closing to stepping into the FX market, while at the same time officials from Japan and Korea will be hoping that the joint statement with the U.S. helps to strengthen the credibility of verbal intervention as well," MUFG strategist Lee Hardman said.
The Japanese currency JPY=EBS strengthened to 153.96 to the dollar on Thursday, which nudged down 0.1% to 154.27, within sight of Tuesday's 34-year low of 154.79.
Market participants have raised the bar on possible intervention by Japanese authorities to prop up the yen, now pinpointing the 155 level from 152 previously, even if they believed Japan could step in at any time.
Still, given the dollar's broad strength, Wei Liang Chang, a currency and credit strategist at DBS, said their models suggest the risk of intervention may have even shifted to the 156 range, as Japanese authorities consider the yen's performance against a handful of other currencies that have depreciated.
The yen has lost some 8.3% in value against the dollar in 2024, but it has fallen against other currencies as well, down nearly 5% against the euro EURJPY=EBS and down almost 7% against the Chinese yuan CNHJPY=R CNYJPY=R .
Japan last intervened in the currency market in late 2022, spending an estimated $60 billion to defend the yen.
EURO, STERLING EDGE UP The euro EUR=EBS , meanwhile, edged up 0.1% to $1.068, after Wednesday's 0.5% gain, pulling away from a five-month low touched on Tuesday. Sterling GBP=D3 was last up 0.1% at $1.2467.
The dollar index =USD , which measures the U.S. currency against six others, was last down 0.12% but still within reach of this week's five-and-a-half-month high of 106.51 hit on Tuesday. The index is up 4.5% this year.
Markets are barely pricing in half a percentage point in cuts from the Fed this year, compared with an expectation for at least six quarter-point cuts at the start of the year. Traders see September as the most likely starting point, compared with June just a couple of weeks ago, based on the CME FedWatch Tool.
U.S. economic activity expanded slightly from late February through early April and firms signalled they expect inflation pressure to hold steady, a Federal Reserve survey showed on Wednesday.
Fed Governor Michelle Bowman on Wednesday said progress on slowing U.S. inflation may have stalled, and it remains an open question whether rates are high enough to ensure inflation returns to the Fed's 2% target.
"In our view it will take a run of lower CPI readings for the FOMC to cut interest rates in September," said Kristina Clifton, senior economist at Commonwealth Bank of Australia.
In cryptocurrencies, bitcoin BTC= skimmed the $61,000 level ahead of the widely anticipated halving event at some point this week. It was last up 0.3% on the day at $61,055.
