Dollar gains against yen as Trump's trade war intensifies

The dollar extended its gains against the yen for a third consecutive day, climbing 0.2% to 146.85, primarily driven by escalating U.S. trade tensions as President Trump announced new 25% tariffs on Japan and other partners, alongside threats of further levies on sectors like copper and semiconductors. This upward movement in USD/JPY was further supported by a fifth day of rising U.S. yields and increased JGB yields amidst fiscal concerns ahead of Japanese elections, while bilateral trade talks remain stalled over issues like Japan's rice market.

Analysis

The U.S. dollar is exhibiting sustained strength against the Japanese yen, rising 0.2% to a two-week high of 146.85 for its third consecutive day of gains. This appreciation is primarily fueled by escalating U.S. trade protectionism, underscored by President Trump's announcement of 25% tariffs on Japan and other partners, with further unspecified trade actions against at least seven countries pending. The upward momentum in USD/JPY is compounded by diverging and domestic yield dynamics; the move is supported by a fifth straight day of gains in U.S. yields and a sharp rise in JGB yields stemming from fiscal uncertainty ahead of Japan's critical upper house election on July 20. Bilateral trade negotiations between the U.S. and Japan appear to be at an impasse over agricultural protections, making a near-term resolution unlikely. While the dollar index remains firm, the impact is selective, with the euro holding steady amid reports of potential EU tariff exemptions, contrasting with minor declines in sterling, and the Australian and New Zealand dollars.

Key Decisions for Investors

• The combination of direct U.S. trade pressure on Japan and supportive yield differentials suggests continued strength in the USD/JPY pair; investors could consider maintaining long positions while watching for any de-escalation in rhetoric.
• Monitor the upcoming Japanese upper house election on July 20, as the outcome could significantly influence domestic fiscal policy, JGB yields, and the government's stance in trade negotiations.
• Given the targeted nature of U.S. tariff policy, it is prudent to differentiate currency exposures, potentially favoring the dollar against currencies of nations explicitly in trade disputes, like Japan, while being more neutral on currencies like the euro, which may secure exemptions.
• Investors should anticipate heightened FX volatility surrounding further U.S. trade announcements and may consider hedging strategies to protect against abrupt policy shifts or unexpected negotiation outcomes.
