Yen nears 160 per dollar, testing resolve of US-Japan intervention

The Japanese yen hovered near the closely watched 160-per-dollar level on Thursday, giving back roughly half the gains from a historic joint US-Japan intervention in late July and raising the prospect of renewed currency-market action by authorities in Tokyo and Washington.

The dollar changed hands at around 159.44 yen during Asian trading hours, up from a low of 155.20 reached during the coordinated intervention that pulled the pair down from near four-decade highs close to 164. The exchange rate's drift back toward 160 has unfolded without any fresh intervention over the past week, leading some analysts to question authorities' resolve.cnbc

Intervention Credibility Under Scrutiny

The late-July operation marked the first time the United States had bought yen to support the currency since 2011. Both governments confirmed the action, which took USD/JPY from roughly 162.80 to around 155 over three days.japantimes+1

"A break above 160 would likely be interpreted as a sign of limited policy resolve," said Shusuke Yamada, head of Japan FX/rates research at Bank of America ↘ 1.14%, adding that the rebound without fresh intervention has eroded confidence in authorities' commitment.cnbc

Tsuyoshi Ueno, executive research fellow at NLI Research Institute, told The Japan Times that further yen weakening "could prompt another coordinated intervention, so market caution will grow, which will likely put a floor under the yen".japantimes

BoJ Rate-Hike Expectations Offer Support

Expectations for a near-term Bank of Japan rate hike provided modest support for the yen. MUFG's Mitsubishi UFJ Financial Group, Inc. ↗ 1.76% Lee Hardman noted that a Bloomberg report indicated Prime Minister Sanae Takaichi's government supports a BoJ hike as soon as September or October. Markets have already priced in roughly 19 basis points of tightening by September, with a hike fully priced by October.fxstreet

A Kyodo report earlier this week said the joint intervention was made possible by BoJ Governor Kazuo Ueda's hawkish comments at the July 31 meeting, where he stated the central bank would "accelerate the pace of rate hikes" if necessary. MUFG concluded that the BoJ has "effectively left itself with no option other than a rate hike" at its September 17-18 meeting.fxstreet

Broader Dollar Picture

The benign U.S. inflation reading for July — consumer prices rose just 0.1% on the month — led markets to reduce the odds of a September Federal Reserve rate hike to 40%, down from 54% a week earlier, according to CME Group's ↗ 1.28% FedWatch tool. The dollar index was flat at 100 on Thursday but remained on course for a 0.4% weekly gain, supported by geopolitical concerns including rising oil prices amid renewed Middle East tensions.investing+1

Goldman Sachs The Goldman Sachs Group, Inc. ↗ 0.74% has noted Japan holds roughly $1 trillion in reserves, leaving ample capacity for further yen-buying operations. With USD/JPY pressing against 160, the market faces what Bank of America's Yamada described as a test: whether "successful intervention that pushes USD/JPY below 155 would have strengthened perceptions of strong commitment" — or whether authorities will allow the line in the sand to be crossed.cnbc+1
