🚨 Japan’s bond market just flashed its weakest signal in 16 years.
The country’s 2-year government bond auction just collapsed in demand.
This tiny crack could ripple into U.S. rates, mortgages, and the entire Fed outlook.

A government bond is like an IOU. Investors lend money to the government, and in return, they get interest plus repayment at maturity.
In Japan they’re called JGBs (Japanese Government Bonds). In the U.S., they’re Treasuries. They are the foundation of each country’s finances.
This auction was for 2-year JGBs. That means Japan borrows today and pays investors back in two years.
These short bonds are usually in high demand because banks use them as collateral and they are considered very safe. Which is why what just happened is so alarming.
We are living through the largest U.S. Treasury collapse on record.
20-year bonds are down ~38% since 2020, a 100-year record.
Even the Volcker inflation era didn’t see losses this steep.

First, what is a Treasury?
When you buy a U.S. Treasury bond, you’re lending money to the government. They promise to pay you interest (called a coupon) and then return your money when the bond matures.
Safe, right? Except prices can swing if yields change.
What’s a yield? It’s the return you earn on a bond. If a $100 bond pays $5 interest, its yield is 5%.
But bond prices and yields move in opposite directions.
If new bonds pay more interest, old ones are less attractive → their price falls.
