US tariffs on Japanese goods, including cars, are set to decrease by 16th September according to Japan’s trade negotiator Akazawa. This update aligns with previous reports. The USD/JPY is slightly lower, trading at approximately 147.30.
Despite the tariff reduction, trade disputes between Japan and the US remain unsettled. While a presidential order on auto tariffs has been issued by Washington, no action has been taken on the most-favoured-nation status for pharmaceuticals and semiconductors, a situation that is unchanged.
Price Movements and Economic Fundamentals
With the news of US tariff reductions on Japanese goods largely priced into the market, we see the USD/JPY’s slight dip to 147.30 as a temporary reaction. The real play is not the tariff announcement itself, but the economic fundamentals that will dominate once this news becomes official on September 16th. Therefore, we should be cautious about expecting significant further yen strength from this development alone.
The underlying economic picture suggests the dollar may find support again soon. Recent data shows US inflation for August 2025 came in slightly hot at 3.4%, and markets are now pricing in a 70% chance the Federal Reserve will hold interest rates steady through the end of the year. This contrasts sharply with Japan’s situation, where the economy is showing signs of slowing.
Japan’s own recent numbers are not encouraging, with second-quarter GDP growth for 2025 coming in at a disappointing 0.8% annualized rate. This sluggish performance limits the Bank of Japan’s ability to raise interest rates, keeping the yen fundamentally less attractive than the dollar. This divergence between a firm US policy and a dovish Japanese one is the more powerful, long-term driver for the currency pair.
Derivative Trading Strategies
For derivative traders, this points toward positioning for a potential rebound in USD/JPY after the September 16th tariff date passes. We could consider buying short-term call options on USD/JPY with strike prices around 148.50 or 149.00 to capitalize on a move higher. This strategy allows us to define our risk while betting that the wider interest rate differential will reassert its influence.
We must also remember the market’s memory of what happened back in late 2022 when the pair moved above the 150 level, prompting direct intervention by Japanese authorities. While we are not there yet, any rapid move toward that threshold will put traders on high alert for official warnings. This historical precedent acts as a psychological cap on the pair for now.
The unresolved trade issues regarding pharmaceuticals and semiconductors are a source of lingering headline risk. This means implied volatility in USD/JPY may not fall off as much as expected post-September 16th. It might be wise to avoid selling volatility and instead look for opportunities where options are underpricing the risk of a sudden policy statement from either Washington or Tokyo.
