Japan’s finance minister, Katsunobu Kato, discussed with Kyodo News the trade agreement with the US. He confirmed that it did not contain any mention of foreign exchange rates.
Kato stated there was a distinct conversation regarding forex issues with Bessent during their discussions in Tokyo. This statement addresses worries about prior remarks from Trump accusing Japan of intentionally keeping the yen weak.
Focus On Forex Warnings
We believe the clarification from Mr. Kato, separating trade from currency talks, sets the stage for unilateral action. This means traders should focus less on trade rhetoric and more on the direct warnings about “excessive volatility” from current Japanese authorities. These warnings have become the primary signal for intervention, moving beyond the scope of past discussions.
The Ministry of Finance has backed its words with significant capital, spending a confirmed ¥9.8 trillion in April and May 2024 to support the yen. This level of spending, similar to the record interventions in late 2022, proves that authorities have a low tolerance for the yen weakening past the 155-160 per dollar level. For us, this establishes a soft ceiling on the currency pair, creating a clear risk for those holding long dollar-yen positions.
We anticipate implied volatility for dollar-yen options will remain elevated, especially as the currency pair drifts toward levels that have previously triggered action. Derivative traders should consider strategies that profit from sharp, sudden moves rather than slow trends, such as buying puts to hedge against a rapid drop. This is because intervention often causes a rapid 3-5 yen decline within hours, wiping out unprepared positions.
Interest Rate Differential Impact
Despite the risk of intervention, the fundamental driver remains the vast interest rate differential between the Federal Reserve’s policy rate, currently above 5%, and the Bank of Japan’s rate near zero. Historically, such a wide gap creates a powerful carry trade that puts persistent weakening pressure on the yen. We therefore view any intervention-led yen strength as a temporary opportunity to reposition, rather than a long-term trend reversal.
