The US Treasury Secretary expressed views on Fed rates and had input for the Bank of Japan (BoJ), suggesting the BoJ could lag in managing inflation. This raised questions on the relative weakness of the JPY against the USD.
A recent US-Japan trade agreement includes a 15% baseline tariff on Japanese exports, potentially muting US criticism of Japanese trade practices. Nonetheless, Japan’s finance ministry may prefer avoiding additional scrutiny from US authorities.
Boj and Tariffs Impact
The BoJ will consider the effects of US tariffs on the Japanese economy, with market rates not yet fully adjusted for a 25-basis point hike in six months. Despite a short-lived rally in the JPY, a USD/JPY forecast of 145 within three months is maintained, assuming continued rate hike speculation.
The primary signal we are seeing is a continued policy difference between the United States and Japan. Recent US inflation data from July 2025 registered a persistent 3.5%, reinforcing the view that the Federal Reserve will not be cutting rates in the near term. This contrasts sharply with the Bank of Japan, which appears content to lag in its own inflation fight.
The new 15% tariff on Japanese exports to the US puts the Japanese economy in a difficult spot. We have already seen preliminary export data for July 2025 show a 4% dip in shipments to the US, hitting the auto sector particularly hard. This economic headwind makes it less likely that Japan’s finance ministry will intervene to strengthen the yen, as doing so would only add to the pain for their exporters.
This setup feels very similar to what we saw during the 2022-2024 period, when a wide gap in interest rate policy caused the yen to weaken significantly against the dollar. The fundamental drivers for a stronger dollar and a weaker yen are firmly in place once again. We believe the path of least resistance for the USD/JPY pair is upwards.
Trading Strategy for Usdjpy
Given this outlook, we think traders should consider buying USD/JPY call options with expirations in the next three to four months. With the pair currently trading around 141.50, looking at strike prices around 143 or 144 allows for a cost-effective way to position for a move towards the 145 target. This strategy provides upside exposure while defining your maximum risk to the premium paid.
The main risk to this view is an unexpected hawkish shift from the Bank of Japan. The market is not yet pricing in a full 25-basis point rate hike in the next six months, so any commentary suggesting a faster timeline could trigger a sharp, albeit possibly short-lived, strengthening of the yen. Therefore, keeping positions sized appropriately is essential.
