The global economy is performing better than previously anticipated this year, despite persistently elevated energy prices. The Organisation for Economic Co-operation and Development has upgraded its global growth forecast for 2026 to 2.9 percent, up from the earlier estimate of 2.8 percent, citing the artificial intelligence investment boom and resilience in several major economies as key factors offsetting the drag from high oil prices.

However, the OECD also cautioned that this resilience does not signal the end of energy-related challenges. Should Middle East conflicts persist, keeping oil prices elevated through next year, and if El Nino weather patterns drive up food costs, the global economy could face more pronounced downward pressure in 2027. The organisation has outlined eight core observations in its latest economic outlook.

High Oil Prices Have Not Derailed Growth as Initially Feared

When the OECD released its June forecast, it had assumed that tensions between the United States and Iran would ease earlier, allowing energy prices to retreat. In reality, oil prices have remained elevated for a considerably longer period. Despite this, global growth has demonstrated notable resilience, prompting the OECD to slightly raise its growth projection for this year to 2.9 percent. Meanwhile, average inflation across G20 economies is now expected to reach 4.1 percent this year, marginally higher than the previous forecast of 4.0 percent, reflecting the ongoing pressure energy costs are placing on price systems.

AI Investment Surge Emerges as the Most Significant Growth Buffer

A critical factor supporting global economic performance is the rapid and sustained expansion of artificial intelligence-related investment. The United States, along with several semiconductor and electronics exporting economies, is benefiting from increased capital expenditure on data centers, chips, and related infrastructure development. This investment wave has created a clear divergence in economic performance. On one hand, countries directly affected by Middle East conflicts and disruptions to energy transportation are seeing their growth prospects deteriorate. On the other hand, economies involved in the AI supply chain, semiconductor production, and electronic equipment exports are experiencing accelerated growth. This divergence is particularly evident in the revised forecasts for Saudi Arabia and South Korea. The OECD now projects Saudi Arabia's economy will contract by 1.8 percent this year, a sharp downgrade from the previous expectation of 3.2 percent growth. Conversely, South Korea, as a major electronics exporter, has seen its growth forecast for this year substantially raised from 2.6 percent to 3.7 percent. This highlights a defining characteristic of the current global economy: AI investment is emerging as a powerful counterweight to energy shocks.

AI Further Boosts U.S. Growth Prospects

AI investment is also improving the outlook for the United States economy. The OECD now expects the U.S. economy to grow by 2.2 percent in 2026, up from the previous forecast of 2.0 percent, with growth of 2.1 percent projected for 2027, also higher than the earlier 1.8 percent estimate. This upward revision primarily reflects the continued expansion of AI infrastructure investment, technology capital spending, and related industrial activity. In essence, while the U.S. economy is feeling the strain of high energy prices, AI investment is generating a sufficiently strong source of new demand to cushion the impact of the energy shock.

Europe and Japan Improve This Year But Weaken in Next Year's Outlook

The OECD has also raised its growth forecasts for the Eurozone and Japan for 2026, while simultaneously downgrading projections for 2027 in both regions. This suggests that the impact of higher energy costs may become more apparent next year. Significant divergence remains within the Eurozone. France's economy is now expected to grow by just 0.4 percent this year, making it the weakest performer among the G7 nations, with the previous forecast having been 0.7 percent. Germany's growth projection, in contrast, has been upgraded from 0.7 percent to 1.1 percent. These differences illustrate that even as the overall Eurozone growth picture improves, individual countries remain highly sensitive to energy costs, fiscal conditions, and external demand dynamics in varying degrees.

Risks Are More Concentrated in 2027

While this year's growth forecast has been raised, the OECD is taking a more cautious stance on 2027. This is because the impact of high energy prices on the real economy typically operates with a lag. Should oil prices remain elevated, corporate costs, household purchasing power, and trade conditions will gradually be affected more significantly. At the same time, if El Nino-related weather patterns lead to reduced agricultural output, food prices could also rise again. This means price pressures from both the energy and food fronts could intensify simultaneously in 2027.

Central Banks May Continue Tightening, But Increases Expected to Be Limited

With energy prices persisting at high levels, the OECD now expects inflation in 2027 to be higher than previously forecast. As a result, central banks in several countries may need to implement further rate increases. However, the OECD believes the scale of any tightening will likely be relatively limited. There is currently no clear evidence that rising energy prices have broadly transmitted into wages or wider core inflation. The OECD attributes this to the faster response from central banks this time around. Compared to the post-pandemic inflation surge, policymakers have begun tightening earlier in an attempt to contain energy price increases before they generate more widespread second-round inflation effects.

Federal Reserve May Raise Rates Once More This Year

In the United States, the OECD projects core inflation will decline from an average of 3.3 percent this year to 2.5 percent next year. Against this backdrop, the OECD expects the Federal Reserve to implement one more 25 basis point rate increase before the end of this year, followed by rates remaining on hold through 2027. The European Central Bank is also expected to follow a similar path. The Bank of Japan is likely to continue its tightening cycle, with the key policy rate projected to rise to 2 percent by the end of 2027. The Bank of England is expected to maintain rates until the second half of next year before beginning to cut.

Under Worst-Case Scenario, Global Growth Could Slip to 2.3 Percent Next Year

The OECD identifies the greatest risk to the global economy as multiple shocks occurring simultaneously. If high oil prices persist into next year, compounded by El Nino-driven food price increases, stock market declines, and further rises in bond yields, global financial conditions would tighten considerably. In such a scenario, global economic growth could fall to 2.3 percent next year, significantly below the current baseline projection. The signal from this OECD report is not that the global economy has escaped the effects of high oil prices, but rather that current growth resilience is stronger than expected. The AI investment wave and expansion in several major economies are temporarily offsetting the energy shock, but whether this buffer can be sustained remains dependent on how oil prices, food costs, and financial conditions evolve in the future.

In summary, the global economy is performing better than previously expected this year, but risks are mounting for 2027. The key factors to monitor are whether high energy prices transition from a short-term shock into persistent cost pressures, and whether the growth momentum from AI investment can continue to offset these negative impacts.
