Japan’s Finance Minister Kato is worried about changes in foreign exchange rates, which he blames on speculators. He stresses the need for a stable currency that reflects economic realities but does not comment on specific forex levels. Kato’s remarks come after a significant drop in the yen’s value, with the USD/JPY exchange rate around 150.74. His comments aim to support the yen during these fluctuations.

Potential Impact of U.S. Tariffs

Kato also talked about how U.S. tariffs could affect exports, saying it requires careful observation. He notes a general agreement that the U.S. trade deficit is not sustainable. Japan is dedicated to meeting its commitments under the trade deal with the United States and plans to implement the agreed terms steadily. We are witnessing typical verbal intervention, showing officials are uneasy about the yen’s weakness as the USD/JPY hovers around 150.74. This is a critical level, recalling that authorities intervened heavily in October 2022 when the pair first crossed 150. Kato’s comments hint that the risk of actual intervention to strengthen the yen has increased significantly.

Interest Rate Differences

The yen is under pressure due to the large difference in interest rates between Japan and the United States. The U.S. Federal Reserve rate is near 4.75%, while Japan’s rate is only 0.15%. This gap encourages traders to favor the carry trade, making it attractive to bet against the yen. Kato’s worries about speculators are justified, as data from late July 2025 shows that speculative short positions on the yen are near multi-year highs. This extreme positioning could lead to a swift market reversal, or “short squeeze,” if intervention occurs. It’s becoming a crowded trade with increasing risks from official actions. In this context, betting on further yen weakness has become riskier. It may be wise to use options to protect these positions. For instance, purchasing inexpensive out-of-the-money JPY calls can guard against a sudden drop in the USD/JPY rate. Looking back at interventions in 2022 and early 2024, when the pair exceeded 160, these moves can happen quickly and dramatically. The conflict between a strong upward trend and intervention fears is creating anxiety in the market. One-month implied volatility for the currency pair has already risen to over 11% this past week, indicating uncertainty. A strategy that buys this volatility, like a long straddle, could be beneficial in the coming weeks to take advantage of a significant price change.
