The global economy has avoided the collapse many feared when conflict in the Middle East disrupted energy supplies. But that resilience is coming at a cost: oil and gas volatility is reviving inflation, investors are questioning the scale of artificial-intelligence spending, and central banks are preparing to keep borrowing costs high for longer.

The OECD’s latest interim outlook projects global growth of 2.9% in 2026 and 3.0% in 2027. Those figures suggest expansion, not recession, yet they also conceal a sharp deterioration from the conditions that supported the recovery. The organisation says energy disruptions have lifted prices for fuel, fertiliser and other industrial inputs, weakening household demand and business confidence. OECD

Why the shock has not become a global crisis

Several buffers have so far limited the damage. Oil inventories were substantial, producers outside the Gulf added supply, and governments introduced measures to protect consumers and businesses. Continued investment in AI also supported production, trade and corporate spending, according to the OECD.

That combination explains why the immediate economic effects have been less severe than the geopolitical headlines. Supply chains have adjusted, energy markets have found alternative sources, and companies with pricing power have preserved margins. The United States has remained particularly strong: October payrolls rose by 165,000, while unemployment edged down to 4.1%, according to market reporting cited by Reuters and other financial analysts.

Yet resilience should not be confused with immunity. Energy is an economy-wide input. Higher prices raise transport and production costs, squeeze real incomes and force central banks to choose between supporting demand and restraining inflation.

Central banks face a politically difficult choice

The dilemma is already visible in market expectations. Stronger-than-expected US employment has reinforced bets that the Federal Reserve could raise rates again in December. In Europe, inflation has also accelerated as energy costs rise. A market briefing reported eurozone headline inflation at 4.0% in October, with energy prices up 20.8% year on year. FXCM

Higher rates could prevent a temporary energy shock from becoming embedded in wages and services prices. But they would also increase mortgage payments, raise financing costs for companies and put further pressure on heavily indebted governments. The policy risk is asymmetric: acting too slowly may prolong inflation, while acting too forcefully could turn a fragile expansion into a downturn.

“The world economy has weathered the energy supply shock ... better than expected,” the OECD said, while warning that inflationary pressures and uncertainty continue to weigh on the near-term outlook.

Supporters of tighter policy argue that credibility matters. If households and businesses begin to expect permanently higher inflation, temporary supply disruptions can produce lasting price increases. Critics counter that interest rates cannot create more oil or reopen damaged infrastructure; tightening policy may therefore reduce demand without addressing the original cause.

AI investment is both support and vulnerability

AI spending has become one of the main pillars of global growth. Data centres, semiconductors, software and electricity infrastructure are drawing enormous capital commitments, helping offset weakness in other sectors. The OECD specifically identifies AI-related investment as a source of continued activity.

But financial markets are increasingly challenging the assumption that every dollar invested will quickly produce an equivalent economic return. A recent technology-stock sell-off intensified despite strong corporate earnings, as investors questioned large capital-expenditure plans and the debt financing behind them. BNP Paribas

A correction would not necessarily end the AI boom. It could redirect capital toward projects with clearer commercial value. The danger lies in concentration: if a small group of technology companies, lenders and infrastructure suppliers is carrying too much exposure, falling valuations could weaken investment well beyond the sector.

What comes next

The central question is the duration of the energy disruption. The OECD outlines two broad paths: a limited shock followed by easing prices, or a prolonged crisis that spreads through energy, food and industrial markets. Under the more favourable path, growth can recover as inventories replenish and inflation declines. Under the darker one, rate increases and weaker consumption could reinforce each other.

Governments therefore face pressure to target relief rather than broadly subsidise consumption. Protecting low-income households may preserve demand while limiting the fiscal cost. At the same time, diversifying energy supply and accelerating efficiency investment would reduce exposure to the next disruption.

The outlook is not a simple story of collapse or stability. Growth remains positive because companies, consumers and governments have adapted. But each adaptation—higher borrowing costs, public subsidies, concentrated AI investment or alternative energy supplies—creates new trade-offs. The next phase will be determined less by one headline number than by whether policymakers can prevent an energy shock from becoming an inflation shock, a financial shock and finally a demand shock.
