Here is something that never makes the headlines the way it should: wars are inflationary. Not sometimes. Not usually. Almost always.
When bombs fall on a Ukrainian wheat field, bread gets more expensive in Egypt. When Houthi drones hit a tanker in the Red Sea, shipping costs spike for factories in Germany. When sanctions cut off Russian oil, petrol queues form in countries that never had anything to do with the conflict.
The world is more connected than most people realise. And war is the most destructive virus that can spread through that network.
The Three Ways War Pushes Prices Up
War does not cause inflation in one simple way. It causes it in three, and they all hit at the same time.
1. Supply destruction
When a factory, port, or farm gets destroyed or shut down, the stuff it was making simply disappears from the market. Less supply with the same demand means higher prices. This is Economics 101, except it happens overnight instead of gradually.
Ukraine is the clearest recent example. Before the 2022 invasion, Ukraine supplied around 10% of the world's wheat and 15% of its corn. When the war started, those exports collapsed. Countries that depended on cheap Ukrainian grain — Egypt, Lebanon, Somalia — suddenly faced a food crisis. Prices did not just rise. They jumped.
2. Supply chain disruption
Modern production is a chain. Break one link and the whole thing gets slower and more expensive.
The Red Sea crisis that began in late 2023 is a perfect case study. Houthi attacks on shipping forced cargo vessels to reroute around the Cape of Good Hope — adding two to three weeks to delivery times and significant fuel costs. For companies that run on just-in-time inventory, those delays meant production stoppages, emergency air freight, and higher costs passed on to consumers.
One conflict in one corner of the world. Supply chains broken on every continent.
3. Energy price shocks
This is the most powerful channel. Energy touches everything. When energy gets expensive, food gets expensive, transport gets expensive, manufacturing gets expensive. It is the inflation multiplier.
Russia is the world's largest natural gas exporter and one of the biggest oil producers. When the West sanctioned Russia in 2022, Europe suddenly needed to buy energy from elsewhere — at prices set by a panicked market. The result was the worst energy price crisis in Europe since the 1970s oil shocks.
The Lag Effect — Why You Feel It Late
Here is the thing most people do not understand about war and inflation: the prices do not rise the day the war starts. They rise months later, when the supply disruption works its way through the system.
A grain shortage in Ukraine in March does not become higher bread prices in the UK until July or August. A spike in oil futures in January does not hit petrol station prices until spring. By the time you feel it at the checkout, the cause is already old news.
This lag is exactly why tracking geopolitical risk in real time matters. If you wait until inflation shows up in the CPI data, you are already six months behind.
2026: The Picture Right Now
As of today, there are 22 active armed conflicts being tracked by the World Tension Meter. That is not a normal number. The global average over the past three decades was around 12 to 15.
The Middle East remains the biggest energy risk. Any escalation involving Iran — whether direct or through proxies — could take significant oil supply off the market instantly. Oil markets are already thin. There is not much spare capacity to absorb a shock.
Trade tensions between the US and China continue to disrupt semiconductor supply chains, which ripple into everything from cars to washing machines.
And the war in Ukraine, now in its fourth year, has permanently restructured European energy markets in ways that keep energy costs elevated even when prices dip temporarily.
What This Means For You
You cannot control geopolitics. But you can watch it.
Watching the right signals — conflict intensity, energy prices, trade disruption — gives you a head start on where inflation is heading. That is worth something whether you are a household planning a budget, an investor allocating assets, or a business managing costs.
The World Tension Meter aggregates exactly these signals into a single daily score. When the score is high, history says inflation pressure is building. When it drops, some relief may be coming.
Today's score is 81 out of 100. Extreme Fear. That tells you something.
