Insolvency

Insolvency is the condition of owing more than one owns, liabilities exceeding assets, or being unable to pay debts as they come due. It is the underlying disease of which default and bankruptcy are symptoms. Lehman Brothers' 2008 failure, the largest bankruptcy in US history at 613 billion dollars of debt, began as insolvency concealed by optimistic asset marks.

Why it matters

Insolvency is often invisible until it is sudden. Institutions can operate for months or years with liabilities quietly exceeding assets, meeting daily obligations from incoming funds, and the moment confidence breaks, withdrawals reveal the hole all at once. This is the anatomy of bank runs, and it repeated almost exactly in crypto: FTX and Celsius in 2022 continued taking deposits while insolvent, and customers learned the truth only when withdrawals froze.

The recurring lesson is that solvency claimed is not solvency proven. Financial regulation, deposit insurance, capital requirements, and audit regimes all exist to police the gap between an institution's books and reality, with imperfect success.

In the gold vs bitcoin debate

Neither gold nor bitcoin can be insolvent, since neither owes anything, but any custodian holding them can be. Both communities converged on the same principle from opposite directions: gold's historic answer is metal in hand, bitcoin's is keys in self-custody plus cryptographic proof of reserves for institutions. The assets differ, the lesson is identical, unverified custody is a liability wearing an asset's name.
