US tariffs may have ended BOJ's rate-hike cycle, former policymaker says

According to former BOJ policymaker Takako Masai, U.S. trade policies, particularly potential automobile tariffs, pose a significant risk to Japan's exports and economic growth, potentially delaying further interest rate hikes by the Bank of Japan possibly through 2026. Masai, who maintains close ties with current BOJ officials, suggests that the impact of these tariffs could materialize within the next six to twelve months, and that the BOJ may need to maintain low real interest rates to support economic restructuring rather than prematurely raising rates.

Analysis

Former Bank of Japan policymaker Takako Masai's assessment suggests U.S. tariffs, particularly on automobiles, pose a significant threat to Japan's export-driven economy, potentially halting the BOJ's nascent rate-hike cycle and delaying further interest rate increases possibly through 2026. This outlook, carrying a strongly negative sentiment and pessimistic tone, signals a considerable market impact, as Masai, who maintains close ties with incumbent policymakers, anticipates the adverse effects of these tariffs will materialize within six to twelve months, culminating in a "real test" for Japan's economy around 2026. While Masai supported Governor Kazuo Ueda's decision to exit the extensive stimulus program and raise rates to 0.5% in January, she now warns against premature further hikes due to the expected economic damage from U.S. trade policy. This uncertainty has already led the BOJ to revise down its growth forecasts on May 1, despite core inflation persistently exceeding the BOJ's 2% target for over three years, which Masai attributes largely to cost-push factors like rising fuel and raw material prices expected to moderate with softening global demand. In a scenario of a severe economic shock, Masai indicated the BOJ might be forced to revert to deploying "all available means" of monetary support, potentially re-expanding its already vast balance sheet.

Key Decisions for Investors

• Investors should anticipate a prolonged period of accommodative monetary policy from the Bank of Japan, potentially weighing on the yen and warranting a cautious stance on Japanese equities highly sensitive to export performance.
• Closely monitor developments in U.S.-Japan trade negotiations and key Japanese macroeconomic indicators, such as export volumes and industrial output, as these will be critical determinants for any shift in the Bank of Japan's policy trajectory.
• Re-evaluate expectations for Japanese government bond yields and related fixed income strategies, as the probability of further rate hikes diminishes significantly and the potential for renewed or enhanced monetary easing increases if economic conditions deteriorate substantially.
