From Tariffs to AI: The Logic of the Global Economy's Gear Shift in 2026

From Tariffs to AI: The Logic of the Global Economy's Gear Shift in 2026

When Washington announced tariff hikes in April 2025, markets were nearly ready for a long trade tug-of-war. But the "World Outlook 2026" released by Deutsche Bank Research on November 24 revealed a more unusual direction: what truly dominates market sentiment has already become artificial intelligence.

Overall Global Growth Stability Masks a Shift in Momentum

The report expects global real growth in 2026 to be roughly the same as in 2024 and 2025. What really matters, however, is not the growth rate itself, but the fact that the sources of growth are undergoing a dramatic reallocation. The team led by Jim Reid and David Folkerts-Landau believes the United States will re-accelerate as trade uncertainty fades and household incomes recover, with growth broadening beyond AI capital expenditure into a wider range of areas. Germany, long mired in stagnation, may become the most dramatic rebounder among major economies, as new fiscal stimulus translates into actual demand. Elsewhere in Europe, momentum will gradually stabilize after absorbing a relatively strong 2025. China is deliberately slowing its pace under "anti-involution" reforms, while India continues its structural rise and is expected to overtake Japan in 2026 to become the world's fourth-largest economy.

This general optimism is not a balanced prosperity, but rather a manifestation of "divergent growth." Each major economy appears to be seeking its own independent growth path based on its own macroeconomic constraints and political cycle.

AI: The Structural Implications of the Market's Central Theme

Why is AI a more central market variable than tariffs? Because tariffs affect trade flows in the short term, while AI defines the long-term productivity frontier. The Deutsche Bank research team expressed a relatively clear view on the AI investment boom: given the current pace of technological progress, it is hard to believe this will not translate into meaningful productivity growth. At the same time, however, the technology's beneficiaries and losers will only become clear gradually after 2026.

In the United States, AI may spark a productivity boom similar to that of the 1990s, adding 0.5 to 0.7 percentage points of annual growth. In Europe and Japan, AI is expected to address population aging and structural labor shortages. In China, it is a key lever for completing industrial upgrading and escaping "involutionary" competition. But AI is not yet a "completed revolution"; it is an early experiment still fraught with enormous uncertainty. 2026 is precisely the stage when technology and reality begin to test each other.

Fiscal Policy Returns as the Engine of GrowthWhen the effectiveness of prolonged accommodative monetary policy reaches its limit, fiscal policy returns to center stage in the global economy. The U.S. budget deficit could rise to 6.7% of GDP in 2026, serving as both a foundation for economic stability and a source of unease in longer-term markets. Germany has finally shifted away from its fiscally conservative stance, pivoting toward expansionary defense and infrastructure investment. The report notes that a large share of defense orders flows to domestic producers, expanding Germany's fiscal multiplier beyond expectations and lifting the entire euro area.

This is the real turning point of the post-crisis era: sovereign debt is regaining strategic legitimacy. Fiscal spending is no longer used merely to smooth cyclical fluctuations, but to cope with geopolitical conflict, industrial competition, and the technological race. Yet it also means sovereign bond markets will carry greater pricing weight and lose patience with policy mistakes. Deutsche Bank expects the U.S. 10-year Treasury yield to reach 4.45% by the end of 2026, with the implied message that markets are not ready to accept the return of a low-interest-rate era.

Europe's Defensive Rise and Deep Pressures

The euro-area economy maintains resilience under external pressures. Growth is around 1% in 2025 and is expected to rise to 1.5% in 2026 (year-on-year in the fourth quarter), thanks to fiscal support, recovering real incomes, and spillovers from some AI-related investment. But Europe cannot rest easy. The direct cost of U.S. tariffs is estimated at about 0.5% of GDP and is likely to affect the second half of 2025 and the first half of 2026. Moreover, structural dependence on both the United States and China, along with defense spending needs squeezing an already high deficit, makes Europe's long-term growth trajectory noisy.

The more severe challenge is a supply-side contraction driven by tight labor markets and population aging. This will generate sustained upward inflationary pressure and could push core inflation back above 2% by 2028. The European Central Bank has decided to stay on hold, with the first rate hike unlikely until mid-2027. This is a new form of expectations management: tolerating inflation above target while hoping that fiscal and structural reforms can close the productivity gap.

Central Bank Rates: Patience May Be the Most Expensive Policy

The pace of global central banks will become more divergent in 2026. The Federal Reserve is expected to cut rates twice more, bringing rates below 3.5% by the end of the year, but subsequent action will depend on the policy preferences of the new leadership and the space for its independence. The European Central Bank chooses to stand pat, keeping the policy rate at 2% over the medium term. This delay reflects a wait-and-see stance toward fiscal expansion and geopolitical uncertainty.

With inflation returning to a "new normal," central bank power is being challenged. Whether it is internal U.S. constraints on the Fed's independence or EU political fragmentation suppressing structural reform, the range on which monetary policy can rely will change. Inflation has not returned to its pre-pandemic level, yet policymakers appear ready to move forward with higher inflation expectations.

The Deeper Implications of China Slowing Down ## The Deeper Meaning of China's Slowdown

China's GDP growth is expected to slow to 4.5% in 2026. This is not the "growth protection" narrative markets once knew, but rather the result of "anti-involution" reforms and supply-side readjustment. The marginal benefits of consumer stimulus policies are diminishing, and the government is focusing more on regulating corporate competition, curbing inefficient expansion, and improving the pricing environment. Inflation is expected to recover gradually, with consumer prices rising 1.5% and producer prices turning positive in the second half of 2026. For the world, China's slowdown does not necessarily mean a collapse in demand, but may represent an attempt to shift from quantity-driven growth to quality-driven growth. The policy tone of the 15th Five-Year Plan suggests that Beijing has a firmer assessment of its own technological strength and economic resilience than in the past.

India: At the Threshold of Entering the Core of the Global Growth Narrative

India surpassing Japan to become the world's fourth-largest economy may look like a statistical event, but behind it lies a historic window shaped by demographics, technology outsourcing, infrastructure, and capital markets. Viewed over a longer horizon, 2026 could be a significant marker of a shift in the center of gravity of the global economy. If India can claim the position of the third-largest economy by 2028, it would mean greater polarization in global demand patterns and industrial chain configurations.

The Next Cycle Will Be Defined by Structure

Putting this patchwork of countries together, 2026 appears on the surface to have no major crisis and to require no "savior-style" policy breakthroughs, yet in reality every region is witnessing the exit of old models and the emergence of new ones. Tariffs as a surface-level variable are being overlaid by deeper fiscal resolve and technological revolution; the geographic distribution of economic activity, interest rate ceilings, and the boundaries of industrial policy are all shifting at the same time.

For investors and policymakers, the most important lesson of 2026 may not be predicting recession or inflation, but judging what forces will shape the next growth cycle. Deutsche Bank Research sets the tone for 2026 as "never a dull moment," reminding people that the world does not become monotonous simply because there is no crisis—it is precisely this complex gear-shifting that will determine the winners and losers for years to come.
