Global growth outlook and recent momentum
- Pre-conflict global growth forecast for 2026 was raised to 3.4 percent.
- Despite major trade disruptions and policy uncertainty, late‑year momentum came from:
- private sector adaptation to a changing business environment;
- lower US tariffs than originally announced;
- some fiscal support;
- favorable financial conditions coupled with strong productivity gains and a tech boom.
- The Middle East conflict has halted this momentum, with the closing of the Strait of Hormuz and damage to critical hydrocarbon facilities raising the prospect of a major energy crisis.
War’s economic impact — transmission channels
- The shock’s ultimate magnitude depends on conflict duration and scale and on how quickly energy production and shipment normalize.
- Three principal channels:
- Higher commodity prices act as a negative supply shock, raising costs for energy‑intensive goods and services, disrupting supply chains, lifting headline inflation, and eroding purchasing power.
- Amplification via wage‑price dynamics as firms and workers try to recoup losses, risking wage‑price spirals where inflation expectations are poorly anchored.
- Heightened macro risks and prospect of tighter monetary policy could trigger sudden financial market repricing: much lower asset valuations, higher risk premia, capital flight, dollar appreciation, tighter financial conditions, and weaker aggregate demand.
Scenarios and quantitative projections
- Reference forecast (assumes a short‑lived conflict and a moderate 19 percent increase in energy commodities prices in 2026):
- Global growth: 3.1 percent in 2026.
- Headline inflation: 4.4 percent in 2026.
- Adverse scenario (sharper increase in energy prices, rising inflation expectations, some tightening of financial conditions):
- Global growth: 2.5 percent in 2026.
- Inflation: 5.4 percent in 2026.
- Severe scenario (energy supply dislocations extend into next year, inflation expectations markedly less anchored, financial conditions tighten sharply):
- Global growth: 2 percent in 2026 and 2027.
- Inflation: exceeds 6 percent.
Differential country impacts
- Importers are highly exposed, especially low‑income and developing economies with vulnerabilities and limited buffers.
- Gulf energy exporters face:
- economic fallout from damaged infrastructure;
- production disruptions;
- export constraints;
- weaker tourism and business activity.
- Remittances will fall in countries that supply migrant workers to the region.
Lessons from the 2022 commodity price surge
- The 2022 episode following Russia’s invasion of Ukraine pushed global inflation to the highest since the 1970s but was followed by synchronized tightening and disinflation without a recession.
- Key differences now:
- 2022 had elevated inflation pressures from post‑pandemic supply‑demand imbalances, tight labor markets, and abundant liquidity.
- Today, softer labor markets and normalized balance sheets have eased underlying pressures, though inflation remains above target in some countries, notably the United States.
- Evidence suggests a return to a flatter supply curve, making disinflation more costly.
- Persisting scars from 2022:
- Permanently higher price levels have raised cost‑of‑living concerns and made inflation expectations more sensitive to new price increases.
Policy guidance and priorities
- Central banks:
- Can generally look through an energy‑price surge only as long as inflation expectations remain well‑anchored.
- If medium‑ or long‑term inflation expectations drift up, restoring price stability must take precedence over near‑term growth, with a swift tightening.
- Exchange rate flexibility allows monetary policy to focus on price stability; foreign exchange interventions or capital flow management measures may be considered in some cases, in line with the Integrated Policy Framework.
- Fiscal policy:
- Untargeted measures (price caps, subsidies) are frequently poorly designed and costly.
- Given limited fiscal space, any fiscal support should be narrowly targeted and temporary, with clear sunset clauses and consistent with medium‑term fiscal plans to rebuild buffers.
- Avoid fiscal stimulus when inflation is rising to not complicate central banks’ task.
- Preserve price signals: price controls and export restrictions often backfire, raising underlying prices, causing rationing, and shifting adverse spillovers to other countries.
- Direct, targeted transfers to vulnerable households and firms typically provide greater relief at lower fiscal cost than broad subsidies.
- Financial and macroprudential response:
- If financial conditions tighten sharply and global activity deteriorates markedly, monetary and fiscal policy should be ready to pivot to support the economy and safeguard the financial system, alongside appropriate financial and liquidity policies.
Resilience, structural priorities, and geopolitical context
- The international order is under growing strain: fraying alliances, new conflicts, and national‑security concerns shape economic policy.
- Geopolitical tensions are reshaping a more multipolar world with waves of trade restrictions from major economic blocs, harming international cooperation and growth, but trade is also being rerouted through new partners and regional agreements.
- Long‑term priorities:
- Promote diffusion and adoption of advances in artificial intelligence, especially agentic AI, while investing in skills to ease labor‑market transitions.
- Accelerate adoption of renewable energy to strengthen resilience to energy shocks, improve energy security, and support the climate transition.
- With the right policies — including a swift cessation of hostilities and the reopening of the Strait of Hormuz — the damage can remain limited; strengthening global cooperation and the role of international financial institutions remains vital.
