Solvency, and reading a run

By the end of this lesson you can

  • Distinguish solvency from liquidity, and explain why an asset-liability mismatch causes a run
  • Explain how Celsius's illiquid, leveraged positions and a depositor run led to a freeze and bankruptcy
  • Compute why on-demand liabilities against illiquid assets are fragile regardless of headline solvency
  • Read a run on-chain from accelerating outflows and forced deleveraging

This lesson opens with Celsius Network, June to July 2022.

What happened
Celsius was a centralized lender that took customer crypto deposits, paid high yields, and deployed the funds to earn more, much of it in illiquid or leveraged on-chain positions: staked ether that could not be redeemed on demand and traded at a discount, and collateralized loans on protocols like Aave and Maker where falling prices forced Celsius to keep adding collateral to avoid liquidation. Its liabilities, customer deposits, were withdrawable on demand; its assets were not. After the Terra collapse in May 2022 shook confidence, depositors began to run, and Celsius could not turn its illiquid assets into cash fast enough to meet the withdrawals. On 12 June 2022 it froze withdrawals, and in July it filed for bankruptcy with a balance-sheet hole later put at roughly 1.2 billion dollars. Much of the structure, the staked positions, the loans, the scramble to post collateral, was visible on-chain as it happened.
The decision point
Solvency and liquidity are different, and a protocol or lender can be arguably solvent on paper and still fail, because what kills it is the mismatch between when it owes and when it can pay. Celsius owed depositors on demand and held assets it could only sell slowly and at a loss, which is the exact structure of a bank run: as soon as enough depositors doubt they can get out, they all try at once, and the institution cannot liquidate illiquid assets fast enough to satisfy them, so it freezes or fails even if its total assets nominally exceed its liabilities. Reading this on-chain has two parts. Solvency: are the assets worth at least the liabilities, and how liquid are they. The run: are withdrawals accelerating and is the entity being forced to deleverage, sell, repay, post collateral, under pressure. Celsius is the case where both were readable, and the fatal fact was not a missing dollar but a mismatch between on-demand liabilities and unsellable assets.

What you will be able to answer

  • What sank Celsius structurally?
  • Solvency versus liquidity?
  • Why can a solvent entity still fail?
  • How do you read a run on-chain?

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested

Celsius's balance-sheet hole is commonly cited around 1.2 billion dollars from its bankruptcy filing; figures shifted through the proceedings. The characterization of its assets as illiquid and leveraged is drawn from its on-chain positions and filings.

Some Celsius positions and liabilities were off-chain and not fully visible on-chain; the lesson uses the on-chain-visible portion (staked assets, DeFi loans, the run) to teach solvency-versus-liquidity reading, and the off-chain gap is the subject of the next lesson.
