Why Do Bond Prices Fall When Interest Rates Rise?
Imagine you bought an old bond that pays 2% per year. That was a decent deal — until it wasn't. Now the ECB or Fed raises rates, and suddenly there are new bonds paying 4%. Your 2% bond is suddenly outdated. Who would buy it? Only if you slash the price.
The Real-World Example
You had €10,000 in a 2% bond. Rates climb to 4%. To make your bond attractive to anyone, you have to drop the price from €10,000 to roughly €8,500 — otherwise no one touches it. That's about a 15% loss on paper. And it happens instantly, not over a year.
Why Professionals Care
Anyone parking money in bonds thinking "it's safe" misses the point: bonds are just paper. When rates shift, the value shifts. This is the exact risk most beginners overlook — and then they lose money on something that was "supposed" to be safe.
The Mental Model
Think of a 2% bond like an old phone. When a new one with 4% appears, the old one's resale value tanks. You can only sell it cheap. That exact dynamic happens in bond markets — and it doesn't just affect pro traders. It hits your savings account when your bank invests in bonds.
The Key Insight
Rates and prices move opposite. It's not magic, it's math. And that's why pros watch carefully: whoever buys 4% bonds cheap today could own a fortune two years from now if rates fall again.
