Japan's economy expands more than expected in second quarter despite U.S. tariff headwinds

Japan's economy expanded 0.3% quarter-over-quarter in Q2 2025, surpassing forecasts with 1.0% annualized growth, primarily driven by net exports. This resilience occurred despite significant U.S. tariff headwinds, including a 25% duty on auto exports and a new 15% blanket tariff enacted post-quarter. While the Bank of Japan upgraded its FY2025 growth forecast to 0.6%, it cautioned about potential slowdowns in overseas economies and declining domestic corporate profits due to global trade policies.

Analysis

Japan's economy demonstrated surprising resilience in the second quarter of 2025, with quarter-over-quarter GDP expanding 0.3% and annualized growth reaching 1.0%, both figures significantly surpassing economists' forecasts. This outperformance was driven entirely by net exports, which contributed 0.3 percentage points to GDP growth, masking domestic stagnation. However, this positive headline is tempered by a deceleration in year-over-year growth to 1.2% from 1.8% in the prior quarter, suggesting underlying momentum may be waning. The growth occurred despite a challenging trade environment, including a 25% U.S. tariff on the critical automobile sector, which accounted for 28.3% of total exports in 2024. While the Bank of Japan upgraded its fiscal year 2025 growth forecast to 0.6%, it simultaneously issued a significant warning about a prospective slowdown in overseas economies and a decline in domestic corporate profits due to global trade policies. This cautionary outlook is further compounded by a new post-quarter trade deal that imposes a 15% blanket tariff on all U.S. exports, clouding the future for Japan's export-led economy.

Key Decisions for Investors

• Given that Q2 growth was solely dependent on net exports and new tariffs are now in place, investors should exercise caution with unhedged, long positions in Japanese export-oriented sectors, particularly automotive manufacturers.
• The conflicting data of a headline GDP beat against decelerating year-over-year growth and negative central bank guidance suggests a mixed outlook; investors should monitor high-frequency trade data and Q3 corporate earnings for the first signs of the new 15% tariff's impact.
• The Bank of Japan's explicit warning on declining corporate profits, despite a formal growth forecast upgrade, signals a material risk to equity market performance, warranting a potential re-evaluation of earnings models for Japanese indices.
