Japan Q2 GDP slides past expectations as capex, private spending slow

Japan's Cabinet Office released preliminary GDP data for April–June 2026 on the 17th, showing seasonally adjusted real GDP grew 0.3% from the previous quarter, translating to an annualized growth rate of 1.1%. While the economy extended its expansion to a third consecutive quarter, the pace of growth fell notably short of market expectations, weighed down by persistently shrinking capital expenditure, stagnant private consumption, and the Iran war's upward pressure on energy costs—a severe test for the world's fourth-largest economy, which is heavily resource-dependent.

Markets had anticipated Japan's second-quarter real GDP to grow 0.5% quarter-on-quarter, with annualized growth ranging between 2.0% and 2.2%. The actual figures, however, missed across the board. On an annualized basis, the 1.1% growth rate not only undershot the 2.0% consensus estimate but also came in below the revised 1.9% recorded in the first quarter.

Breaking down the demand-side components, the biggest drag on the quarter's performance was capital investment. Japan's capital expenditure fell 1.2% on a non-annualized basis in the second quarter, against market expectations of 0.5% growth and following a revised 1.0% decline in the first quarter. Private consumption was equally disappointing, remaining essentially flat from the previous quarter rather than expanding as markets had forecast. Government consumption rose 1.6%, serving as one of the few bright spots supporting the economy.

On the export front, second-quarter exports grew 0.5%, a slowdown from the prior quarter's pace. Japan's automotive and semiconductor industries continued to benefit from global demand, particularly chip demand fueled by the artificial intelligence (AI) boom, providing support for major manufacturers such as Toyota Motor Corp. and Honda Motor Co.

The impact of the Iran war on Japan's economy is clearly visible in the latest GDP figures. The Strait of Hormuz, a critical shipping lane for Persian Gulf oil bound for Asia, has effectively been blockaded due to the conflict, driving global oil prices higher. Brent crude is currently trading around $88 per barrel—below the peak above $110 reached earlier this year but still far above the roughly $65 level seen a year ago.

For Japan, which relies almost entirely on imported oil, rising crude prices directly inflate the import bill and push up consumer prices. Taro Saito, an economist at NLI Research Institute, noted that this quarter's GDP figures were "worse than originally expected, with both consumption and capital investment weak." He elaborated: "This growth wasn't driven by economic strength, but rather by a decline in import volumes, as oil imports became difficult due to the Strait of Hormuz shipping issues." In other words, reduced imports actually made a positive contribution to the GDP growth calculation, masking the true weakness in domestic demand.

The Japanese government has released a portion of its strategic petroleum reserves and is actively seeking alternative shipping routes to alleviate supply disruption pressures.

The yen's trajectory continues to shape Japan's economic outlook. Following the historic joint intervention in currency markets by the United States and Japan, the yen briefly rebounded from a 40-year low near ¥164 per dollar (approximately NT$33) to around ¥155 (approximately NT$31). However, the rally failed to hold, and the yen has since weakened again. On the 17th, following the GDP release, the currency was trading around ¥159.11 per dollar (approximately NT$32).

The weak yen exerts a dual impact on Japan's economy. On one hand, it boosts the translated value of overseas earnings for major exporters like Toyota, which raised its profit forecast on August 4. On the other hand, since imported commodities such as oil are priced in dollars, yen depreciation means Japan pays more yen for every barrel of crude purchased, further intensifying imported inflation and eroding households' real purchasing power.

Inflationary Pressures and Policy Response

Japan's second-quarter GDP deflator rose 2.6% year-on-year on a preliminary basis, exceeding market expectations of 2.3% and reflecting persistent upward price pressure. Japan's July producer price index (PPI) surged 7.2% year-on-year, driven by the combined effects of high oil prices and the weak yen, indicating that corporate cost pressures continue to accumulate. Market participants expect more companies to pass costs on to consumers, further fueling inflation.

Against the backdrop of accelerating inflation, there is widespread anticipation that the Bank of Japan will raise interest rates in the near term. The BOJ has already revised its economic growth forecast for the fiscal year ending next March upward to 0.6% from a previous 0.5%. Markets widely expect the BOJ to announce a rate hike at its policy meeting next month, and such a move could strengthen the yen, creating a new variable for exporters.

Political Pressure on the Takaichi Government

The weak economic data poses direct political pressure on Prime Minister Sanae Takaichi. After her two predecessors both stepped down amid public discontent over inflation, the Takaichi government has aggressively expanded support for voters. Following a large-scale stimulus package and broad energy tax rebates at the end of 2025, her administration rolled out additional relief measures earlier this year. In late July, the Japanese government announced it would cut the food consumption tax from 8% to 1% starting next April, in an effort to ease cost-of-living pressures.

Nevertheless, Takaichi's approval ratings continue to decline gradually. While still relatively high compared to some of her predecessors, persistently rising oil and consumer prices are steadily eroding her public support base.

Looking ahead to the third quarter, economists broadly expect Japan's growth momentum to slow further. A survey conducted by the Japan Center for Economic Research between July 28 and August 4 showed that economists on average expect Japan's real GDP annualized growth rate to be near-flat this quarter, at a marginal 0.05%.

The multiple challenges currently facing Japan's economy—energy supply disruptions caused by the Iran war, imported inflation exacerbated by the weak yen, and the twin weaknesses in capital expenditure and consumption—are unlikely to be resolved quickly in the short term. Amid ongoing global geopolitical turbulence, whether Japan's economy can regain growth momentum in the second half of the year will depend on the trajectory of energy prices, the pace of BOJ monetary policy, and whether the Takaichi government's stimulus measures can effectively boost private demand.
