Yen Gains Footing After Intervention, Dollar Slips on Mideast Hopes

The yen was slightly firmer at 157.60 per US dollar, after easing about 0.4% from Monday's high of 155.20 in the previous session. It remained well above recent 40-year lows of around 164 per dollar.

The US will do "whatever it takes" to support Japan's efforts to stabilise the yen, treasury secretary Scott Bessent said on Tuesday, after last week's joint intervention by Washington and Tokyo to buy the Japanese yen hit bearish traders.

He also told public broadcaster NHK that he was sure Bank of Japan Governor Kazuo Ueda will "do what is best" for the country's economy. The comments followed a series of remarks from Bessent calling for higher Japanese interest rates, heightening expectations that the BOJ could raise rates at its next policy meeting on Sept 17 and 18.

"With US involvement adding credibility to the intervention, and with warnings that further coordinated action remains possible – the move has given authorities an effective tool to buy time while they wait for fundamental factors to turn more positive," IG market analyst Tony Sycamore wrote in a note.

Oil retreat dents dollar

The US dollar index, which tracks the currency against six major peers, was little changed at 99.85, struggling to find direction after hitting a six-week low on Monday. The euro was steady at US$1.1533 and sterling traded flat at US$1.3458.

The kiwi dollar was roughly down 0.3% at US$0.5878 after New Zealand's unemployment climbed to a decade-high of 5.6% in the second quarter. The Aussie was flat at US$0.7053.

Oil prices extended their falls, with Brent crude futures down 0.3% in early trade on Wednesday after tumbling 5% in the previous session, as signs of a possible diplomatic off-ramp to the Iran conflict eased fears of supply disruptions and prompted traders to unwind risk premiums.

Comments from Qatari and US officials fuelled hopes for a negotiated resolution. Qatar said on Tuesday mediators were making progress in efforts to end the war, raising hopes oil flows through the Strait of Hormuz could improve.

Interest rate-sensitive two-year US Treasury yields hovered near two-week lows as easing oil prices prompted traders to reprice for lower odds of a Federal Reserve rate hike in September.

Attention will shift to Friday's non-farm payrolls figures. The odds of a September hike have receded to 60% from 75% a week ago, according to CME Fedwatch.
