You've probably heard about a stablecoin "losing its peg."
One day it's $1.00. The next it's $0.87. Then panic. Then collapse.
The usual explanation is technical, bad algorithm, thin reserves, a bank run. But there's a deeper reason these breaks happen. And it has nothing to do with crypto.
It has to do with how money actually works.
In the previous article, we established one idea: money is not a thing you hold. It's a record others agree to honor.
Today we go one level deeper, because that difference, quiet in good times, loud in bad ones, is exactly what determines whether a stablecoin survives a crisis or doesn't.
Here's something most people never think about.
When you get paid, your employer doesn't hand you dollars. They instruct their bank to update a number in your bank's system. Your bank now owes you that amount. That's your "dollar."
When your bank needs to settle with another bank, say, because you sent a wire, they don't use your deposit. They use a completely different kind of dollar: reserves held at the Federal Reserve.
And when you pull cash out of an ATM? That's a third form, a physical note issued by the central bank.
These are three different instruments, all called “dollars”. All treated as equivalent in daily life, even though they are structurally distinct.
The technical term for this fixed one-to-one exchange rate between them is par. And par is the thing that makes the whole system feel seamless.
Here's what most people miss: the reason $1 in your bank account equals $1 in cash isn't physics. It's a social agreement, backed by law, regulation, and political will.
Think about it this way.
