Expert Warns of 4% Global Inflation
Adam Posen of the Peterson Institute for International Economics is warning that the world needs to be prepared for 4% inflation to become "the new normal" in 2026. The forecast is driven by persistent wage pressures and energy volatility, particularly from Middle East instability.
Posen's forecast stands in contrast to other major financial institutions. J.P. Morgan Research, for instance, anticipates global core inflation will remain stable at 2.8% in 2026, while Goldman Sachs is forecasting U.S. core PCE inflation (the Fed's preferred measure) will fall to 2.2% by December 2026. The Peterson Institute's more hawkish view for the U.S. is driven by several factors beyond general wage and energy concerns. These include the delayed pass-through effects of tariffs, a fiscal deficit potentially exceeding 7% of GDP, and monetary policy that they argue is looser than the Federal Reserve acknowledges. On the wage front, the Atlanta Fed's Wage Growth Tracker registered a 3.6% increase in January 2026. Globally, while real wage growth has turned positive, the International Labour Organization reports that in 45% of countries, minimum wage increases have not kept pace with inflation, sustaining pressure for higher pay. Recent events have sharply illustrated the "energy volatility" factor. Following military strikes in the Middle East in early March 2026, ICE Brent crude futures were projected to climb towards $100 per barrel. Simultaneously, European natural gas prices saw potential spikes towards €80-100/MWh amid risks to Qatari LNG supplies. Historically, a 4% inflation rate would sit well below the median global peak of 8.7% seen in the third quarter of 2022 but significantly above the 1.9% median rate in Q3 2020. The World Bank identifies oil price shocks as the primary driver of global inflation variation over the last five decades. Divergent paths are expected for different regions. While Posen's concerns are focused on an overheating U.S. economy, J.P. Morgan forecasts inflation will moderate in Europe. In the Eurozone, core inflation stood at 2.4% in February 2026, with energy prices actually falling 3.2% year-over-year.
