Collateral

Collateral is an asset pledged by a borrower to secure a loan, which the lender can seize if the borrower defaults. Lenders discount collateral through a haircut to protect against price swings; bitcoin-backed loans commonly require a loan-to-value ratio near 50 percent, meaning 2 dollars of bitcoin pledged for every dollar borrowed.

Why it matters

Collateral is the foundation of credit. The quality of what can be pledged, how easily it is valued, transferred, and liquidated, determines how much lending an economy can support and at what price. Government bonds dominate modern collateral markets because they are liquid and standardized. When collateral values fall, margin calls force sales that depress values further, the mechanism at the heart of most financial crises, which is why haircuts and collateral quality attract so much regulatory attention.

In the gold vs bitcoin debate

Gold has served as collateral for centuries and central banks still swap and lend against it. Bitcoin's case as collateral rests on its mechanics: it transfers globally in an hour, divides to eight decimal places, can be verified by anyone, and can be margined around the clock. Its volatility demands deep haircuts, and custody of pledged coins remains a trust problem. Both assets compete for the same role: neutral collateral that is no one's liability.
