Key Takeaways:

USDJPY breached the 160 barrier for the first time in the current cycle, bringing Japanese intervention risk to its highest level since authorities spent ¥11.7 trillion defending the yen in April and May.
USDJPY cracked the 160 barrier on June 3, pushing the yen to its weakest level since authorities spent ¥11.7 trillion on intervention, as Middle East uncertainty and widening rate differentials fueled demand for dollars. The pair touched 160.00 in early Asian trading before settling just below the threshold, with traders watching for signs of official action.
"The 160 level is widely viewed as a line in the sand for the Ministry of Finance, and the risk of a renewed round of rate checks or actual intervention has increased markedly," said Masafumi Yamamoto, chief currency strategist at Mizuho Securities. "If dollar-yen breaks above 160, the risk of surpassing the April 30 high would increase markedly."
The dollar index held at 99.17 on Tuesday, while the euro edged up 0.03% to $1.1634 and sterling gained 0.07% to $1.346. Against the yen, the greenback traded at 159.66 before breaching 160 on Wednesday, approaching the April 30 high that triggered the previous intervention round. The Australian dollar added 0.1% to $0.7162, and the New Zealand kiwi gained 0.07% to $0.5933.
A sustained break above 160 could force the Bank of Japan to intervene for the first time since late May, when it spent a record ¥11.7 trillion across multiple sessions. If no intervention materializes, markets may interpret the level as permission for further yen weakness, potentially pushing USDJPY toward 162. Finance Minister Satsuki Katayama said Tuesday the authorities stood ready to respond in the currency market as needed, declining to comment on specific exchange-rate levels.
The dollar's advance was tempered by developments in the Middle East, where Lebanon announced a limited ceasefire between Hezbollah and Israel on Monday. While the agreement signaled a degree of de-escalation, it remains limited against the backdrop of a wider regional conflict that has disrupted oil flows through the Strait of Hormuz since the Iran war began on February 28.
"We expect the U.S. and Iran to agree to gradually re-open the Strait of Hormuz and a 60-day extension of the ceasefire to negotiate Iran's uranium enrichment sometime this week," said Kristina Clifton, senior currency strategist at the Commonwealth Bank of Australia. "Good news about the war ending will weigh on the USD because it is a safe haven currency."
The greenback had rallied at the onset of the conflict, buoyed by safe-haven demand and the U.S. economy's relatively limited exposure to energy-driven inflation. However, it has given back some of those gains as uncertainty surrounding the conflict's trajectory persisted. Markets now bet the Federal Reserve's next move will be to raise its benchmark interest rate, compared with expectations for a cut before the war began, given rising energy prices and their impact on inflation.
Traders are now awaiting a speech by Bank of Japan Governor Kazuo Ueda on Wednesday for possible signals on whether the central bank will proceed with a rate increase the following week. The BoJ's policy path has become a critical variable for the yen, with any hawkish tilt potentially narrowing the rate differential that has driven the currency to multi-decade lows.
Later this week, the U.S. Labor Department will release its monthly employment report on Friday, with economists polled by Reuters expecting a gain of 85,000 jobs in May and the unemployment rate holding at 4.3%. The data could sway the Fed's policy path in the near term, with a strong reading reinforcing expectations for a rate hike and further supporting the dollar against the yen.
The last time USDJPY traded above 160 was in April 2026, when Japan intervened at a scale that dwarfed its 2022 operations. The previous intervention round in September-October 2022, totaling ¥9.2 trillion, pushed USDJPY from 151.94 to 144.50 over six weeks. A repeat of that magnitude would imply a move back toward 152-154 if triggered.
