The result is rarely a single, uniform market move: the same shock can hurt one country or asset while benefiting another, and policy responses can alter its course.
How a global shock reaches financial markets
A useful way to understand a market response is to follow the chain from the initial disruption to prices and financial conditions. A pandemic, war or trade-policy shift does not move markets by itself; investors reassess the economic consequences, policy response and risks to cash flows and funding.
- The shock changes activity. A health emergency can restrict production and redirect household spending. Conflict can disrupt energy, food or transport. Trade-policy uncertainty can delay investment or redirect supply chains.
- Output, demand and prices adjust. Disruption may constrain supply, while changes in spending can shift demand between sectors. Commodity prices can transmit the shock across borders, including to countries not directly involved.
- Inflation and policy expectations move. If price pressures appear persistent, markets may anticipate tighter monetary policy; if activity and demand weaken, they may anticipate support. These expectations influence borrowing costs and financial conditions before the full economic effects are known.
- Asset prices and funding respond unevenly. Investors revise expectations for corporate earnings, interest rates, currencies, sovereign risk and liquidity. The direction and scale depend on exposure, policy credibility, market liquidity and investor positioning.
- Financial vulnerabilities can amplify or cushion the shock. Leverage, liquidity mismatches and fragile funding can intensify selling or stress. Fiscal capacity, reserves, a stable domestic investor base and available policy tools can provide room to respond.
These channels interact. For example, an energy supply disruption can raise inflation, change expected interest rates and weaken the outlook for energy-importing economies at the same time. A country that exports the affected commodity may face a different mix of effects.
What the pandemic and the war in Ukraine show about inflation
The inflation surge of 2020–23 illustrates how overlapping shocks can reinforce one another. A Federal Reserve Board paper published in August 2025 by Anna Lipińska, Enrique Martínez García and Felipe Schwartzman describes the episode this way: “The inflation surge in the U.S. and abroad was set in motion by two global events: the COVID-19 pandemic and Russia’s invasion of Ukraine.” The paper’s authors’ views do not necessarily represent those of the Federal Reserve Board.

The pandemic changed supply and spending
Pandemic-related supply disruptions constrained production and logistics, while consumers shifted spending toward goods. Together, those forces contributed to price pressure across countries. A Federal Reserve Board staff note published in June 2024 found that the global component of inflation explained a substantial part of inflation variation across the 26 economies in its GDP-weighted world measure, including in the post-COVID period. The displayed data extend through 2024 Q1; the note links recent inflation to both commodity shocks and global activity shocks.
The Ukraine war added commodity and trade pressures
Russia’s invasion of Ukraine added to commodity-price pressures, particularly through energy and food, and affected trade and capital flows. In remarks on June 21, 2024, IMF First Deputy Managing Director Gita Gopinath described the war as a supply shock that complicated inflation and monetary-policy decisions. She also said Ukraine’s output was roughly 25 percent below its pre-war level; that was a dated estimate, not a current measure. Her remarks noted that the war “has increased fragmentation pressures and raised defense spending as countries implement measures to strengthen their economic and national security.”
Rank #2
The sequence mattered for financial markets: supply constraints and commodity-price increases contributed to inflation, while tight labor markets helped keep inflation above target, according to the August 2025 Federal Reserve paper. As inflation expectations and policy-rate expectations changed, financial conditions changed too. This does not mean every asset fell or that the same pattern applies to every country; exposure to commodities, domestic demand and policy capacity differed.
The global figures are historical, not current readings
An IMF analysis published April 16, 2024 reported that global growth bottomed at 2.3 percent at the end of 2022, shortly after median headline inflation peaked at 9.4 percent. Those figures describe that retrospective account of the episode; they are not current growth or inflation rates.

Why geopolitical risk can have a muted average effect but still matter
Not every geopolitical event produces a large or lasting market move. The IMF’s April 2025 Global Financial Stability Report says geopolitical-risk events generally have modest average asset-price effects. It also warns that major events, including military conflicts, can cause substantial stock-price declines and higher sovereign risk premiums, with cross-border effects transmitted through trade and financial links.
The distinction is important: an average response across events does not describe the consequences of a severe conflict for a particular country or market. The IMF says effects may be more pronounced in emerging markets with limited fiscal space or reserves. Exposure to trade, commodity supply and external financing also shapes how a shock travels.
How different shocks reach markets
Recent crises are easier to compare by their transmission channels than by treating them as interchangeable headlines. The table summarizes the mechanisms described in the cited IMF and Federal Reserve analyses; it is not a ranking of market returns.
| Shock | Main real-economy channels | Possible financial-market transmission | What changes the outcome |
|---|---|---|---|
| COVID-19 pandemic | Production and logistics disruptions; spending rotation toward goods | Inflation and changing expectations for policy rates and financial conditions | Duration of disruption, demand conditions, economic exposure and policy response |
| Russia’s invasion of Ukraine | Energy and food supply, commodity prices, trade and capital-flow disruption | Inflation pressure, monetary-policy tradeoffs and sovereign-risk repricing | Commodity exposure, trade links, fiscal room, reserves and conflict-related vulnerability |
| Trade-policy uncertainty | Potential delays to investment and changes in trade relationships | Reassessment of expected activity, earnings and risk | How uncertainty affects actual decisions, sector exposure and cross-border links |
Trade-policy uncertainty was a distinct source of uncertainty in 2025. A Federal Reserve Board note on the fourth SNB-FRB-BIS high-level conference reported that U.S. and global Economic Policy Uncertainty reached unprecedented levels in April 2025, mostly driven by trade-policy uncertainty. This is a finding about that measure and date, not a statement about every uncertainty index or later periods.

Why policy responses affect the market path
Central banks can influence financial conditions through interest rates, balance-sheet measures and liquidity support. The BIS’s 2024 Annual Economic Report review describes the use of balance sheets and liquidity tools during crises, including dollar swap lines in the global financial crisis, the euro-area sovereign crisis and the COVID-19 crisis. Such measures can address liquidity strains, but they cannot by themselves remove a supply disruption or settle uncertainty about the path of a conflict or trade policy.
Supply-driven inflation makes the tradeoff especially difficult: tightening policy may restrain demand and price persistence, but cannot directly restore interrupted supply. At the same time, allowing persistent inflation to continue can affect expectations and financial conditions. The BIS review emphasizes the limits of monetary tools and the value of coherence across policy domains; it does not imply that one policy response fits every crisis.
What can amplify financial stress
A shock can become a broader financial problem when vulnerabilities interact. In its Global Financial Stability Report published April 22, 2025, the IMF said global financial stability risks had increased significantly amid tighter global financial conditions and heightened trade and geopolitical uncertainty. The report’s market-data cutoff was April 15, 2025, so its assessment is a dated snapshot, not a description of conditions on October 8, 2026 or another later date.
- High valuations: If asset prices assume optimistic outcomes, a change in expected earnings or rates can prompt a sharp repricing.
- Leverage and links between institutions: Borrowing can magnify losses. The IMF highlighted leverage at some financial institutions and links between nonbanks and banks as risks that could reinforce one another.
- Liquidity pressure: Redemptions or margin calls can force sales when investors need cash, potentially adding pressure to prices and funding markets.
- Sovereign debt concerns: Debt-sustainability worries can affect sovereign risk premiums and narrow a government’s room to respond.
- Limited policy buffers: Less fiscal space or fewer reserves can make it harder to absorb cross-border shocks, particularly for vulnerable emerging markets.
Practical lessons for interpreting future market reactions
Past crises are useful as maps of possible transmission channels, not as templates that predict the next move. When assessing a new event, separate the initial repricing from the longer-run economic effects and ask:
- Is the shock mainly supply-driven, demand-driven or both?
- Does it affect energy, food, trade, investment or funding—and which countries and sectors are most exposed?
- Is the disruption likely to be brief or persistent, and what evidence would change that assessment?
- How could inflation and central-bank expectations respond, given the country’s policy framework?
- Could leverage, liquidity mismatches, redemptions or sovereign financing needs amplify the shock?
- What buffers—such as reserves, fiscal capacity or liquidity facilities—may help absorb it?
For financial institutions, the IMF’s discussion supports attention to scenario analysis, stress testing and leverage monitoring. These are institutional risk-management lessons, not instructions for an individual to buy, sell, hedge or hold a particular asset. Outcomes remain country- and exposure-specific, and no past crisis establishes that all markets will move together in the next one.
