USD/JPY May Remain Range-Bound Despite Joint Intervention

HSBC strategists are weighing in on the recent coordinated intervention by Japan's Ministry of Finance and the US Treasury to support the Japanese Yen against the US Dollar. The joint action led to a sharp drop in USD/JPY, but experts caution that this trend may not be sustainable without improved Japanese fundamentals.

Following the intervention on July 30-31, both authorities confirmed their joint action on August 3 and stated they would not hesitate to intervene further if needed. This marks a significant shift from Japan's solo intervention in April-May, which took seven weeks for USD/JPY to recover its pre-intervention levels.

HSBC strategists believe that the market will now be more cautious when rebuilding speculative short JPY positions due to the increasing scale of MoF intervention and involvement by the US Treasury. However, they also note that intervention alone is unlikely to change the underlying trend of USD/JPY, which requires more attractive real interest rates in Japan and reduced fiscal concerns.

According to HSBC's base case, USD/JPY will remain mostly range-bound, capped by periodic MoF intervention but supported by persistently negative real rates in Japan. The range may now be wider due to both USD factors (recent softer US data, less predictable Fed communication, and persistent geopolitical uncertainty) and JPY factors (joint intervention and potential changes involving the Bank of Japan).
