The global economy is entering a split-screen phase: investment tied to artificial intelligence is providing fresh momentum, while energy shocks, high borrowing costs and geopolitical fragmentation keep the outlook fragile. The result is not a clean recovery, but a narrow one, with growth increasingly concentrated in the countries and sectors best placed to benefit from the AI buildout.[1]

That tension was captured in the OECD’s latest interim outlook, which said the world economy is set to slow to 2.9% growth in 2026, even as AI-related investment helps keep activity “marginally better than expected.” The same forecast warned that an entrenched energy shock, volatile bond yields and the risk of poor returns on AI spending could all weaken the picture in 2027.[1]

Why the economy is holding up

The most important support is capital spending, not consumer strength. The OECD said strong investment in data centres, semiconductors and related infrastructure is boosting the United States and lifting technology exports from Japan and South Korea.[1] The World Economic Forum’s September outlook also pointed to AI and defence spending as major growth engines, saying high-tech and AI activity has accounted for nearly half of US private-sector GDP growth over the past year, according to S&P Global.[2]

That concentration matters. The WEF said much of the recent upside has come from economies closely tied to AI and technology value chains, while other regions face weaker growth and greater uncertainty.[2] Its Chief Economists’ Outlook similarly described an uneven global picture, with India and South-East Asia assessed most positively, the United States showing moderate growth, China weakening and Europe still lagging despite modest improvement.[3]

The risks behind the resilience

The main drag is energy. Reuters reported that the OECD sees the Middle East energy shock as increasingly entrenched, with implications for inflation and 2027 growth.[1] That concern is shared more broadly across the policy and business world: the WEF said ongoing conflicts, high borrowing costs and geoeconomic shocks continue to buffet the global economy even as it has held up better than expected.[2]

There is also a direct inflation channel. The Reuters economic roundup noted that the world’s biggest sovereign bond markets are heading for their worst month in years as soaring energy costs fan inflation and the AI boom lifts growth, pushing investors to assume rates may stay higher for longer.[4] That combination is awkward for central banks: growth is not weak enough to justify easy policy, but inflation is not subdued enough to allow quick cuts.[4]

What the split economy means

The current cycle is producing winners and losers at the same time. AI-linked firms, chipmakers, cloud providers, utilities and construction companies building data-centre capacity are benefiting from a wave of demand.[2] By contrast, sectors exposed to energy prices, financing costs and weak household purchasing power are facing a tougher environment.[1]

That creates a deeper structural issue: growth is becoming more uneven across countries and within them. The WEF’s economists said fiscal support, which helped stabilise the world economy after 2020, is now likely to matter less because governments have less room to respond.[3] If that is correct, the burden of adjustment shifts toward the private sector and away from governments, even as many households continue to face stagnant or falling real incomes.[3]

“Strong spending on AI infrastructure” has become a key pillar of resilience, but the same reports warn that energy-market jitters and disappointing AI returns could quickly change the story.[1]

What comes next

The near-term outlook depends on whether AI investment remains broad enough to offset the energy and rate shocks. If the buildout stays strong, it could keep manufacturing, tech exports and parts of the US economy expanding into 2027.[1] If returns disappoint, the economy could be left with high power demand, expensive capital projects and little productivity payoff.[1]

The more immediate policy test is inflation. If energy prices stay elevated, central banks may keep interest rates higher for longer, reinforcing pressure on indebted firms and consumers.[4] If they ease too soon, they risk re-igniting price pressures in an economy where supply shocks remain unresolved.[1]

In practical terms, the world economy is no longer being pulled by one story. It is being tugged by two: a technology-led investment cycle that is stronger than many expected, and a geopolitically driven cost shock that is far from over.[2][1]
