Global Economic Meltdown
Not the end of the world. Just the end of your 401(k).
What it is
A global economic meltdown is a financial crisis deep enough to break the systems that move food, fuel and medicine around the world. Think 1929 or 2008, but larger, with credit freezing up, governments unable to borrow and trade networks seizing. On its own it rarely ends civilization. What makes it dangerous is how it amplifies everything else on this list.
Why it ranks where it does
The warning signs are unusually loud. The IMF says global public debt is at its highest level since the Second World War. Oil is trading near $100 a barrel because of the Iran war. A global bond sell-off pushed the US 10-year Treasury yield to 5.34%, the highest since 2002. We track a prediction market on a US recession by the end of 2027.

What the experts say
Economists disagree about recession timing, but few predict a collapse that ends civilization. Central banks and governments have strong tools for preventing a 1930s-style spiral, which is why this scenario ranks below the war and climate scenarios even though a recession looks fairly likely.
What would move the number
Up
- Bond-market failures or sovereign defaults in large economies
- Bank runs that spread across borders
- Oil price spikes caused by a longer Gulf blockade
Down
- Falling oil prices and yields
- Coordinated central-bank action
- A soft landing in the US and China
