Japan GDP: 0.4% Growth Masked by Falling Imports

Japan's second preliminary GDP estimate for April–June 2026 showed real GDP growth of +0.4% QoQ (+1.4% annualized). Although growth remained positive, it slowed slightly from +0.5% in the previous quarter. The composition, however, points to a deterioration in the quality of growth. Private final consumption expenditure was flat at 0.0%, private nonresidential investment fell 0.9% for the second consecutive quarter, and public demand declined 0.8%, its largest drop in the 12 quarters covered. The main driver of positive growth was the external-demand contribution resulting from a sharp 1.7% decline in imports, giving the expansion the strong appearance of “growth in name only” as all three pillars of domestic demand weakened simultaneously.

Headline Assessment — Japan's 5.5% Nominal Growth Matters More Than 1.4% Real Growth

The most important feature of this release is the divergence between real and nominal growth. According to the Cabinet Office's preliminary GDP data, real GDP grew at an annualized rate of +1.4%, while nominal GDP expanded by +5.5%. On a QoQ basis as well, nominal growth of +1.3% significantly exceeded real growth of +0.4%.

In level terms, nominal GDP stood at ¥689.2 trillion and real GDP at ¥598.9 trillion. Real growth of +1.4% annualized is neither an overheated nor a sharply weakening pace. By contrast, nominal growth above 5% provides a clear tailwind for nominal economic variables such as tax revenues, corporate sales, and debt ratios.

However, the GDP deflator rose 2.6% YoY, slowing from 3.2% in the previous quarter and reaching its lowest level among the 12 quarters covered. This indicates that the price factors that have driven nominal growth are beginning to move past their peak.

Contribution Analysis — Domestic Demand Was Negative, Leaving External Demand to Explain Growth

In short, this quarter's +0.4% growth cannot be explained by domestic demand. Looking at the direction of the components, consumption was flat, while both business investment and public demand declined; no positive contribution from domestic-demand items can be identified. Exports rose modestly by +0.4%, while imports fell 1.7%. Under the definition of GDP, a decline in imports raises the growth rate by reducing the deduction for imports.

In other words, the positive real growth rate was almost entirely attributable to an improvement in net exports, or external demand. This configuration allows for two interpretations.

• Domestic-demand-linked explanation: The decline in business investment and stagnation in consumption compressed demand for imported capital and consumer goods. The fall in imports was therefore a consequence of weakness, suggesting that growth will remain dependent on external demand in subsequent quarters
• Temporary-factor explanation: Inventory adjustment or substitution in response to higher import prices temporarily depressed import volumes. In this case, a rebound in imports in the next quarter could cause the external-demand contribution to turn negative

The fact that business investment has declined for two consecutive quarters supports the first interpretation, while the increase in import costs caused by the rise in the CGPI, discussed below, supports the second. Either way, the common implication is that the external-demand contribution is unlikely to be sustained.

Component Analysis — Consumption Stalls as Business Investment Falls Again

The trend in the major components shows that the slowdown in domestic demand was concentrated in the latest quarter.

The three-quarter run of positive consumption growth came to an end. Real consumption stagnating as the CPI reaccelerated to the upper 1% range YoY indicates that households have limited capacity for real spending. Business investment has declined for two consecutive quarters since the start of 2026, marking its weakest trend during the period covered. The 0.8% decline in public demand was the largest drop in the period covered, and its reversal from +0.5% in the previous quarter amplified the deterioration in domestic demand this quarter.

Exports rose just 0.4%, down sharply from +1.7% in the previous quarter. The limited increase in exports despite continued yen depreciation indicates that quantitative constraints on overseas demand, rather than price competitiveness, are weighing on exports.

Corporate Sentiment and the Yen — Improving Conditions Now, Caution Ahead

The BOJ Tankan survey shows a significant divergence between assessments of current conditions and the outlook. In the Q2 2026 survey, the diffusion index (DI) for large manufacturers rose to 22, up 5 points from 17 previously and the highest level during the period covered. However, the outlook DI was 14, eight points below the current assessment. The gap had been 2 points in the 2025-Q3 survey, 3 points in Q4, and 2 points in 2026-Q1, so it widened sharply in the latest survey. This suggests that companies view their current strong performance as unsustainable.

The exchange rate is one factor behind this caution. The Tankan assumed exchange rate for large manufacturers was ¥151.55 to the dollar, while the BOJ's foreign-exchange market data showed actual rates of ¥160.71 in June 2026, ¥162.55 in July, and ¥158.74 in August. A weaker yen than assumed boosts exporters' yen-denominated earnings. Even so, the deterioration in the outlook indicates that companies expect the earnings tailwind to be offset by headwinds in volumes and costs.

The DI for small and medium-sized manufacturers also improved to 9, but a substantial gap remains with the 37 recorded by large nonmanufacturers. Differences by company size and industry have not narrowed.

Financial Conditions — Rate Hikes and QT Proceed Together, Yet the Yen Continues to Weaken

The BOJ is clearly pursuing monetary normalization. The uncollateralized overnight call rate rose in stages from 0.478% in November 2025 to 0.978% in July 2026, then remained at 0.977% in August and September. The monetary base stood at ¥543.0 trillion at the end of August 2026, down 15.7% YoY, with the pace of contraction accelerating. Policy-rate hikes and quantitative tightening are proceeding simultaneously.

Nevertheless, the real effective exchange rate (2020=100) continued to decline, from 71.8 in September 2025 to 65.0 in July 2026. The nominal effective exchange rate was 67.6 in the same month. The fact that higher domestic interest rates have not supported the yen indicates that factors other than interest-rate differentials are determining yen weakness.

Upstream price pressures are intensifying. The Corporate Goods Price Index (CGPI) rose from 129.8 in March 2026 to 135.8 in July, an increase of 4.6% in four months. The sharp rise to 133.4 in April was particularly notable. The Services Producer Price Index (SPPI) also rose from 113.7 in March to 115.1 in July. Meanwhile, as discussed below, the CPI remains below 2%, indicating that pass-through to downstream prices is still under way. This time lag means that upward pressure on consumer prices remains.

Prices and the Business Cycle — CPI Reacceleration as Energy Effects Fade

The CPI has turned upward again. According to data from the Statistics Bureau of the Ministry of Internal Affairs and Communications (MIC), the July 2026 headline CPI rose 1.9% YoY, the core CPI 1.8%, and the core-core CPI 1.9%. All three accelerated from June (+1.6% / +1.6% / +1.7%). However, they remain well below the roughly 3% levels seen in October–November 2025.

The relationship among the three measures has also changed. From January to March 2026, the core-core CPI exceeded the core CPI by 0.6–0.9 percentage points, as energy prices pushed down overall inflation. By July, the gap had narrowed to 0.1 percentage point. This shows that the fading downward effect of energy prices was the main reason for the reacceleration in headline CPI.

The simultaneous acceleration in CPI and slowdown in the GDP deflator on a YoY basis is not contradictory. The two measures cover different areas. The CPI measures the price of a household consumption basket, including imports, while the GDP deflator covers prices across domestic production and treats imports as a deduction. Given these different scopes, the two indicators can, by definition, move in opposite directions.

The Indexes of Business Conditions indicate expansion. According to the Cabinet Office, the July 2026 coincident index rose to 120.6, the highest level during the period covered, while the leading index rose to 117.9. The coexistence of weakening domestic demand in GDP and a rising coincident index reflects the fact that the coincident index includes supply-side indicators such as production and shipments, while the July data capture a period after the April–June quarter.

Cross-Check with Real-Demand Data — Machinery Orders Flat at a High Level, Suggesting a Rebound Effect in Business Investment

A comparison with monthly real-demand data requires a revision to the interpretation of business investment. The quarterly averages for machinery orders (private-sector demand excluding ships and electric power) were as follows.

After increasing by more than 6% for two consecutive quarters, orders leveled off at a high level in Q2. Because machinery orders lead business investment by 2–3 quarters, the increases from 2025-Q4 through 2026-Q1 suggest a recovery in business investment in the second half of 2026. The two consecutive quarterly declines in GDP-based business investment are therefore more likely to reflect a correction following the +1.3% increase in 2025-Q4 and the timing of construction progress than investment restraint caused by higher interest rates.

However, trade statistics are available only through December 2025, and the Current Survey of Commerce only through January 2025, making it impossible to track external demand and consumption in 2026-Q2 directly. As a reference point, the trade balance improved from a deficit of ¥277.7 billion in September 2025 to a surplus of ¥306.0 billion in November and ¥94.8 billion in December, confirming that the trend toward import restraint had already begun in the second half of 2025.

Time-Series Trends — Cyclically Smoothed Growth and Structurally Weak Domestic Demand

Real growth over the past four quarters was -0.4%, +0.3%, +0.5%, and +0.4%. After recovering from the decline in 2025-Q3, growth has stabilized in the 0.3–0.5% range. This degree of fluctuation falls within the range of cyclical variation and does not indicate that the economy has entered a recession.

Two structural trends can be identified. First, nominal growth has remained well above real growth since 2023. Second, QoQ consumption growth has not exceeded +0.6% even once over the 12 quarters covered. While rising prices inflate nominal GDP, household real spending remains structurally stagnant. Consumption growth of 0.0% amid a widening gap between nominal and real growth is emblematic of this pattern.

Link to the Equity Market — Stocks Price in Nominal Growth, While the Response to the Preliminary Release Is Limited

The TOPIX has risen in line with the expansion of nominal GDP. Its quarter-end level increased from 2,658.73 in 2025-Q1 to 3,994.76 in 2026-Q2, and reached 4,125.80 as of September 7 in 2026-Q3, up 3.3% from the previous quarter. The rise in equities while real growth remains in the 1% annualized range indicates that markets are valuing growth in nominal sales and profits rather than the real growth rate. The weaker yen than assumed in the Tankan also reinforces this assessment.

On September 7, the release date, the TOPIX closed at 4,125.80, up just 0.55% from the previous day. Because the second preliminary estimate primarily contains revisions to the first estimate, the market reaction was limited. A decline of 2.40% was recorded on September 2, but this occurred before the GDP release.

Outlook and Risks — The Key Question Is the Pace of Upstream Price Pass-Through

The outlook can be summarized around three points.

• Pass-through from CGPI to CPI: If the 4.6% increase in CGPI since March 2026 passes through to downstream prices, CPI will accelerate further from +1.9% in July. With consumption already at 0.0%, an additional deterioration in real purchasing power could cause consumption to turn negative
• Reversal of the external-demand contribution: This quarter's positive growth depends on imports falling 1.7%. If imports normalize, the next quarter's real growth could fall close to zero unless domestic demand recovers
• Timing of the business-investment rebound: If the effects of rising machinery orders through 2026-Q1 materialize, business investment will turn positive in the second half of 2026. Conversely, if the flat performance in Q2 continues, a peak in orders would directly delay the investment recovery

In addition, the fact that the Tankan outlook DI is eight points below the current assessment means that companies view the business environment in the second half of 2026 as more challenging than it is today. As the BOJ raises its policy rate to around 1% and contracts the monetary base at a pace exceeding 15% YoY, all three components of domestic demand have moved into negative territory simultaneously. This fact provides a measure of the real economy's resilience to downside risks in the conduct of monetary policy. The two specific indicators to watch in assessing the next GDP release are whether monthly machinery orders can remain in the ¥1 trillion range and whether core-core CPI can return to the 2% range.
