Yen: Psychological Resistance Level and Intervention Concerns — MUFG

MUFG analyst Teppei Ino, reviewing recent USD/JPY movements ahead of the Jackson Hole symposium, noted that the pair is engaged in a fierce tug-of-war around the 160 psychological level. USD/JPY opened near 159, then repeatedly tested the 160 mark, which serves as a key psychological resistance level amid traders' close watch for possible Japanese intervention.

**Intervention Risk vs. U.S. Treasury Yields**

News of an expanded U.S. Treasury buyback program briefly triggered dollar selling, pushing USD/JPY toward 158. However, the decline did not persist, and as short-term U.S. Treasury yields rebounded, the pair quickly recovered and approached the 160 threshold again. This rapid round-trip suggests the market is caught between intervention threats and yield differentials—on one hand wary of Japanese action above 160, on the other supported by elevated U.S. Treasury yields.

**Pre-Jackson Hole Caution**

Market focus is now shifting to the upcoming Jackson Hole global central bank symposium. According to MUFG analysts, USD/JPY may continue to trade within its current range until the meeting delivers clearer policy signals. Any hints on the U.S. rate cut path or Japan's policy normalization could break the fragile balance. If the U.S. signals dovishness, the yen could firm and intervention risks may temporarily ease; conversely, if U.S. yields push higher, the 160 psychological line will face a more severe test.
