A Supply Shock, Not a Demand Shock

The World Bank forecasts a 23% rise in commodity prices in 2026, including 32% for energy, 25% for metals and 40% for precious metals. What sets this shock apart is its nature. Global oil supply is expected to fall 5.2%, the steepest drop in forty years outside the 2020 recession. Demand, for its part, is contracting by 2.5%. Prices are therefore rising despite declining consumption, a sign that the constraint comes from supply.

From Blockade to Freight: The Transmission Chain

The mechanism is visible in physical flows. Before the April US blockade, Iran held nearly 150 million barrels in floating storage. By mid-October, only 866,000 remained. Chinese refiners, deprived of cheap Iranian crude, are turning to West Africa and Brazil, at premiums of up to 20 dollars per barrel above Brent.

Freight amplifies the phenomenon. Shipping crude from the United States to China cost up to 80 million dollars per supertanker, ten times the pre-war average. The rate has fallen back to around 60 million, still prohibitive for Asian buyers. The rise in energy costs then spreads to fertilizers (+14% expected), then to food (just over 10%).

Central Banks Under Constraint

This pattern poses a classic dilemma: raising rates in the face of imported inflation risks weighing on already weakened growth. Markets are pricing it in. For the Fed meeting, 90.6% of participants bet on a status quo and 9.4% on a quarter-point hike. The World Bank report itself raises the specter of higher inflation and more restrictive monetary policy if the shocks persist.

On sentiment, the CNN Fear & Greed Index stands at 34.46 on October 28, against 31.0 the day before. The ten-year AAA eurozone yield is 3.37% as of October 27. These levels reflect moderate caution, not a generalized flight from risk.

The Limits of Interpretation

Several factors nuance the picture. Commodity prices are expected to fall 7% in 2027, and freight has already shed about 10 dollars per barrel on major routes since its peak. Above all, the file contains no direct measure of inflation or historical sentiment series, and OECD leading indicators are absent for lack of usable data. The link between commodities and consumer prices therefore remains a risk documented by institutions, not an effect measured here.

Conclusion

The 2026 shock is indeed a supply shock, with identifiable transmission channels, from blockade to freight to prices. It narrows central banks' room for maneuver. Whether it translates into lasting inflation will depend on the evolution of the conflict and oil inventories, two unknowns that available data do not resolve.
