Japanese Yen Hits 40-Year Low: Tokyo Prepares for Intervention as Dollar Pressure Mounts
The Japanese yen has plunged to its lowest point since 1986, raising fresh concerns about currency stability and forcing Tokyo to consider direct market intervention once again.
The yen has shed more than 2% of its value this quarter alone, extending what is now a four-quarter losing streak — the longest such run since 2022, when the currency weakened for seven consecutive quarters. On Tuesday, the USD/JPY pair briefly reached an intraday high of 162.4, before settling around 162.1 at the time of reporting.
**Tokyo Signals It Will Not Stand Idle**
Japanese officials have made clear they are monitoring the situation closely and are prepared to step in. Finance Minister Satsuki Katayama confirmed that authorities are ready to act at any moment, including through decisive measures coordinated with the United States. Chief Cabinet Secretary Minoru Kihara echoed this stance, stating that Japan aims to build an economy more resilient to exchange rate volatility, while keeping all intervention options on the table.
This is not the first time Tokyo has moved to support the yen. Between late April and late May, Japanese authorities deployed a record 11.7 trillion yen — equivalent to approximately $72.25 billion — in an effort to slow the currency's decline. Despite this massive outlay, the yen eventually resumed its downward trajectory once market support was withdrawn.
**Bank of Japan Tightens, But Doubts Linger**
The Bank of Japan has been gradually tightening its monetary policy. It most recently raised its benchmark interest rate to 1%, following an earlier hike to 0.75% in December. However, analysts remain skeptical that either rate hikes or direct intervention can fundamentally alter the currency's direction.
Carol Kong, a currency strategist at Commonwealth Bank of Australia, noted that intervention is no longer a matter of whether it will happen, but when. That said, she argued that any such action is unlikely to reverse the broader USD/JPY uptrend. Her forecast calls for the pair to continue climbing toward 164 by early 2027.
**US Rate Expectations Add Fuel to the Fire**
A significant driver behind the yen's weakness is the growing expectation that the US Federal Reserve will raise interest rates again. Traders currently price in a 63.1% probability of a Fed rate hike by September, supported by three consecutive months of stronger-than-expected payroll data. This expectation has widened the yield differential between US and Japanese assets, making the dollar increasingly attractive relative to the yen.
All eyes are now on Thursday's US jobs report for June. A Reuters survey forecasts approximately 110,000 new positions added during the month. A strong result would reinforce bets on further Fed tightening, potentially pushing USD/JPY even higher. Conversely, a disappointing figure could give Tokyo a more favorable window to intervene, as a softer dollar would reduce the scale of action required.
**What Comes Next**
The situation remains fluid. With the yen at multi-decade lows, intervention risk is elevated, but structural factors — including the US-Japan interest rate gap and persistent dollar strength — continue to work against a sustained yen recovery. Markets will be watching Thursday's employment data closely, as it could either accelerate the yen's decline or briefly ease pressure on Japanese policymakers.
