The global economy enters the second half of 2026 with unexpected momentum, despite two ongoing wars, a sharp rise in energy prices, and persistent geopolitical turmoil. Rather than triggering a generalized slowdown, these shocks have so far been absorbed by an economy anchored by corporate investment, artificial intelligence, and increased defense spending. However, this resilience creates a different problem. Robust growth keeps inflationary pressures alive and pushes interest rates and long-term bond yields higher. For investors, the risk is that the economic "heat" currently supporting markets may ultimately spark financial instability.
What is happening?
The impact of the war in Iran was substantial. Crude oil prices surged by 50%, while natural gas prices doubled over the following six months, raising concerns that elevated energy costs would eventually weaken global economic activity. Instead, economic momentum gained strength. Recent data reveals unexpectedly strong employment in the United States, upward revisions to second-quarter GDP in the Eurozone and Japan, rapid expansion in Chinese exports and imports, and one of the strongest overall increases in corporate profits on record. The result is an unusual combination of robust growth, geopolitical tension, and supply disruptions. This mix keeps inflation under pressure while simultaneously making it harder for central banks to justify lowering interest rates.
The boom in AI investments keeps growth alive
Artificial intelligence has evolved into one of the primary forces supporting the global economy. The massive investments required to construct data centers for AI are generating demand across the construction, technology, electric power, and industrial commodities sectors. Copper illustrates this effect particularly well. The metal, often viewed as a barometer for global industrial activity, is approaching record levels and has nearly doubled in value over five years. Copper prices are supported by several factors, including supply constraints and tariff concerns. However, the expansion of AI infrastructure and rising defense budgets are also generating significant demand. This indicates that the AI boom is not merely a tech narrative. It is increasingly transforming into a major source of real investments and industrial activity.
Global business confidence confirms the momentum
Business surveys reflect a similar picture. Combined manufacturing and services surveys by JPMorgan showed that global production expanded for a fifth consecutive month in August, reaching its highest level in more than two years. Data from the bank indicates that global GDP is expanding at an annualized rate of approximately 3.1%, significantly higher than its estimate for potential growth of 2.3%. Even more importantly, new orders and future production expectations are strengthening. This suggests that current momentum is not simply the result of temporary statistical effects. Businesses continue to expect that demand will remain robust.
Why strong growth can turn into a problem
Under normal conditions, strong economic growth would be an almost universally positive development. The problem today is the specific environment in which this growth is occurring. Energy prices remain high, geopolitical tensions disrupt supply chains, governments are spending heavily on defense, and corporations are aggressively investing in AI. If demand stays strong while supply remains constrained, inflation could prove to be far more persistent. This applies pressure on central banks to maintain or even raise interest rates. And that is where financial risks begin to accumulate.
The bond market is the first line of defense
Long-term borrowing costs have already risen to their highest levels in decades. For investors, this shifts the traditional relationship between economic growth and bonds. During the post-2008 era, investors became accustomed to low growth, low inflation, and ultralow interest rates. Bonds frequently functioned as a buffer when riskier assets declined. That environment may now be disappearing. Deutsche Bank strategist Jim Reid argues that bonds are essentially returning to their traditional role, as investors focus more on income generated by bond coupons rather than anticipating large capital gains from falling interest rates. In other words, bonds are becoming bonds again, rather than serving merely as vehicles for betting on lower yields.
The "new, new normal"
Another interpretation, however, is that the world is neither returning to the pre-2008 environment nor to the unusual conditions of the 2010s. JPMorgan Asset Management strategist David Kelly describes the emerging environment as a "new, new normal." There are still elements of the 2010s, such as aging demographics and economic inequality. There are also similarities to previous periods of geopolitical tension, trade disruptions, and major investment cycles. Yet today's economy possesses another defining characteristic: economic nationalism and trade protectionism have returned on a scale not seen since World War II. At the same time, AI could fundamentally transform productivity. The result is an economic environment that combines technological transformation with geopolitical fragmentation.
The debt burden makes this cycle different
The single biggest difference may be sovereign debt. Governments accumulated massive amounts of debt following the 2008 financial crisis and again during the pandemic to prevent economic weakness from spiraling into something far worse. This debt burden alters how financial markets are likely to behave during the next recession. Historically, government bonds provided substantial protection when economic activity weakened because investors expected rate cuts and rising bond prices. However, with government debt already at historically high levels, investors cannot necessarily take for granted that governments will be able to respond to every downturn with the same degree of fiscal stimulus. This also implies that long-term sovereign bonds may no longer offer the same diversification benefits they provided in the past.
Why investors are becoming more vulnerable
This creates a challenging environment for portfolio managers. They want to stay invested because global growth is strong and corporate profits are rising. Simultaneously, they must protect portfolios against the risk that inflation, interest rates, and pressure on the bond market could ultimately undermine this growth. The traditional strategy of relying heavily on government bonds for diversification may no longer function as effectively. Investors therefore require broader sources of downside protection.
Key market players
Central banks: Facing the difficult task of reining in inflation without needlessly weakening an economy that remains unexpectedly strong. Governments: High debt levels limit their capacity to rely on large-scale fiscal interventions during future downturns. Corporations: Investments in AI and defense are driving growth, but higher financing costs could eventually impact capital expenditure decisions. Fund managers: Must participate in strong economic growth while simultaneously preparing for greater volatility in interest rates and the bond market. Tech companies: Capital expenditures in AI are turning into a major source of global economic demand. Commodity producers: Rising demand for copper, energy, and other industrial raw materials benefits from the investment cycle, while simultaneously feeding inflationary pressures.
What comes next?
The critical question is whether current economic strength can be maintained without triggering a larger shock to inflation and interest rates. If growth remains strong, central banks may have less room for interest rate cuts. If long-term yields continue to rise, governments and corporations will face higher borrowing costs. And if higher borrowing costs eventually begin to slow down investment—particularly the massive spending connected to AI and defense—today's economic strength could transform into tomorrow's weakness. The International Monetary Fund may also revise its forecast for global growth in 2026 upward from the 3.0% estimate published in July. Its projections for 2027 will be in focus, as global growth is already expected to accelerate to 3.4%.
Analysis: The greatest danger is not recession
The greatest danger facing the global economy may not be a recession. It may be overheating. Two wars and dramatically higher energy prices failed to produce the slowdown many anticipated. Instead, investments in AI, corporate spending, defense expenditures, and consumer and business resilience are keeping global growth unusually robust. Yet no economy can grow above its potential indefinitely without consequences. The longer strong growth persists, the harder it becomes for central banks to ease monetary policy. Higher interest rates subsequently feed into sovereign debt servicing, corporate borrowing, and asset valuations. At the same time, unusually high sovereign debt means policymakers have less room to support the economy if something goes wrong. This creates the potential for a financial chain reaction: strong growth fuels inflation, inflation keeps interest rates high, high interest rates push bond yields even higher, and costlier borrowing eventually threatens the investment boom supporting growth in the first place. This is why the current environment is so difficult for investors. The economy is performing well enough that exiting risk assets likely means missing out on substantial gains. However, the very strength supporting those gains creates vulnerabilities elsewhere. There may be no returning to the old "normal" of permanently low interest rates and predictable diversification. Instead, the global economy is entering a period defined by stronger capital investments, higher debt, geopolitical turbulence, protectionism, and technological transformation. The financial risk is not that the global economy is too weak. It may be that it is running too fast—and the financial fire could break out when policymakers are finally forced to slam on the brakes.
