USD/JPY is near 158 after the July intervention at around 160. How do you think about the risk of another one?

By FTC's calculation from ECB reference rates, USD/JPY was 163.91 on 28 July, the highest of 2026, and 160.24 on 31 July, the day Japan's Ministry of Finance bought yen in coordination with the US Treasury. It was 156.68 on 3 August and 158.23 on 5 October (report). Japan confirmed the joint intervention, and said it stands ready to carry out further joint intervention (report).

The Bank of Japan raised its policy rate to 1.25% on 18 September on a 7–2 vote, and its board is split on how fast to go next (report). Tokyo core inflation reached 2.7% in September (report), and the Bank decides again on 30 October.

Intervention risk is one of the hardest things to price, because authorities rarely announce levels in advance. Currency intervention explained covers the history. The calculations above are only reference-rate snapshots, not traded prices.

How do you think about it?

• Do you treat any particular level, or speed of movement, as a warning sign for USD/JPY, and where does that come from?
• Does a Bank of Japan meeting change your view of intervention risk, in either direction?
• How do you manage a position when a policy-driven reversal can happen in minutes?
• Do you trade crosses such as EUR/JPY with the same caution?
