Yen swings as carry trades unwind before BOJ

This piece looks at why the yen climbed to its strongest level against the dollar in a month. Vantage Markets explains that, as of 07:15 (UTC) on 4 September 2026, the unwinding of trades that had borrowed the low-yielding yen to park money in other assets (the yen carry trade unwind) coincided with expectations of a rate hike from the Bank of Japan. With a Bank of Japan decision ahead, prices of yen-linked products can swing sharply in a short space of time, and using leverage raises the risk of losing your capital by the same measure.

Key points to check
- The original flags the Bank of Japan rate decision date (18 September 2026) and the US employment data release (5 September 2026) as dates to watch. It also explains that when Bank of Japan meeting news or intervention headlines land, prices often gap rather than move continuously. That said, 5 September 2026 falls on a Saturday, and the August US employment data had already been released on 4 September 2026, the same day the original was published — the date in the original appears to be an error.
- The possibility of intervention in the currency market by the Japanese authorities is also mentioned. The original explains that intervention is not a signal guaranteeing one direction, but a variable that can shake prices both ways.
- Yen-linked products are generally traded with leverage (a way of trading a large amount on a small margin deposit). Losses grow along with gains, and you can lose all of your capital, so position size should be set with that risk in mind.
