USD/JPY climbed to 161.96 on Monday, pushing the yen to its weakest level against the US dollar since 1986. The pair broke past 161.95, the level that triggered large-scale Japanese official intervention back in July 2024.
The yen keeps sliding even after the BoJ lifted benchmark rates to 1% on June 16, the highest since 1995. Traders price in a persistently hawkish Federal Reserve stance, keeping the wide US-Japan rate gap supportive of USD/JPY carry trades. Ongoing uncertainty around US-Iran diplomatic talks also underpins safe-haven demand for the greenback.
Verbal intervention warnings have ramped up from Tokyo. On June 19, Finance Minister Satsuki Katayama said authorities stand ready to take "bold action" to curb excessive speculative yen declines. Following her meeting with US Treasury Secretary Scott Bessent, she noted the two sides are increasingly aligned on FX policy and agreed to take "bold steps" on currencies if needed.
Official reserve data shows Japan spent a record 11.73 trillion yen ($72.5 billion) intervening between April 28 and May 27 to prop up the yen, drawing down US Treasury holdings to fund the operations. The massive intervention only delivered a temporary yen rebound and failed to reverse the broader downtrend.
A weak yen brings mixed outcomes for Japan. It boosts exporter earnings and lifts the JP225 index, yet lifts dollar-denominated oil and gas import costs, pushing up household prices for food and electricity. A policy rift is also emerging: the government will call for "appropriate" monetary settings in its core economic guidelines, widely seen as a signal to deter further BoJ rate hikes.
Technical View

USD/JPY trades around 161.80, well above the key 20-day EMA at 160.85, retaining a bullish near-term bias as long as this support holds. The RSI stands at 71.61, firmly in overbought territory. While upward momentum stays strong, the indicator signals the pair is ripe for a corrective pause rather than fresh sharp advances.
- Support: Immediate buying interest emerges at the 20-day EMA of 160.85. A sustained break below this level will weaken the short-term bullish setup and open deeper retracement
- Resistance: A decisive break above 162.00 is needed to target 163.00 and 164.00. Broad intervention fears will cap upside momentum around the psychological 162 mark.
Market focus now shifts to US June payroll data due later this week, which will reshape Fed rate expectations and drive the pair’s rate-differential core narrative.
