The Japanese yen is getting tense again as markets watch for a “sudden intervention” ahead of the Bank of Japan meeting
With the Bank of Japan’s September policy meeting approaching, yen traders’ nerves are once again on edge because the market fears Japanese authorities may restart foreign-exchange intervention.
Recently, the yen has been strengthening steadily. Behind this, in addition to bets that the Bank of Japan could raise rates at the September 18 meeting, some investors are also taking precautions in advance against potential government intervention in currency markets.
Notably, Japan has previously chosen to act during long holiday periods, when trading volumes are lower and exchange-rate volatility is more easily amplified. This past April, Japanese authorities carried out their first FX market intervention since 2024 during a holiday period.
Now, the market is starting to speculate that if the USD/JPY rate again surges toward levels in the past that triggered intervention, Japan may take action again.
In short, the current yen market feels like it’s standing at the edge of a cliff. Everyone is watching the Bank of Japan’s every move: expectations for rate hikes, low liquidity during holidays, and pressure on the exchange rate. With several factors stacking up, they could all become the spark that triggers sudden yen volatility.
