USD/JPY – The yen just hit a 40-year low, and Japan may step in

The Japanese yen dropped to around 162.3 per dollar today — its weakest level since 1986. The driver is a wide rate gap: the US sits near 3.75% and may move higher, while Japan holds at just 1%. Capital flows where yields are higher, and right now that means away from the yen.

Japan has been here before. Between April and May, Tokyo spent roughly $72 billion buying yen to slow the slide — but the effect faded within weeks. With the yen now at a fresh low, markets widely expect Tokyo to act again. As one strategist put it: it's a question of when, not if.

Here's what makes this setup dangerous. A huge number of traders are betting the yen will keep falling. If Japan steps in to buy, those bets can unwind all at once — pushing the yen sharply higher in minutes. The higher USD/JPY climbs, the bigger that reversal risk becomes.

Thursday's US jobs report is the next catalyst. A strong print keeps pressure on the yen; any sign of Japanese intervention could flip the move fast.

USD/JPY key levels:

• Resistance: 162.50, then 163.50

• Support: 161.00, then 160.00
