Solvency

What Is Solvency?

Solvency answers the fundamental question about financial viability: if all obligations were called in and all assets liquidated, would there be enough to cover everything owed? An entity is solvent if the answer is yes — positive net equity remains after all debts are settled. An entity is insolvent when total liabilities exceed total assets, meaning it cannot fully repay what it owes even if it sells everything.

The solvency/liquidity distinction is critical and often confused. Liquidity is about now: can you pay the bills due this week, this month? It’s a flow question about whether cash is available when needed. Solvency is about ultimately: are your total assets worth more than your total obligations? It’s a stock question about balance sheet health. A business can be both liquid and solvent (healthy), liquid but eventually insolvent (burning cash sustainably but depleting reserves), solvent but illiquid (profitable business but temporarily cash-strapped), or both insolvent and illiquid (in crisis).

The distinction matters enormously for intervention: an illiquid but solvent institution can be rescued by a lender of last resort (central bank) providing temporary liquidity, because the underlying assets are sound. An insolvent institution needs recapitalisation (new equity to replace lost capital) or restructuring, because the problem is structural rather than temporary. Misidentifying an insolvency crisis as a liquidity crisis — providing liquidity to an entity that is fundamentally insolvent — delays inevitable reckoning while burning rescue resources.

Solvency Ratios

Debt-to-equity ratio — total debt divided by total equity. Higher ratios indicate greater leverage and more solvency risk; ratios above 2–3× require robust earnings to service the debt load comfortably.

Debt-to-assets ratio — total debt divided by total assets. Above 1.0 means total debt exceeds total assets — technically insolvent on this measure. Healthy companies typically maintain ratios of 0.3–0.6.

Interest coverage ratio — EBIT (earnings before interest and taxes) divided by interest expense. Below 1.5× is concerning; below 1.0× means the company can’t cover its interest from operating earnings — a solvency warning signal.

Equity ratio — shareholder equity divided by total assets. Measures what fraction of assets are financed by owners versus creditors. Higher is safer from a solvency perspective.

Solvency vs. Liquidity

Why Is Solvency Important for Traders?

Solvency assessment is the foundational credit risk analysis for any counterparty — whether it’s a company whose bonds you’re considering buying, a bank where you hold deposits, or a crypto exchange where you maintain a balance. FTX’s collapse illustrated the catastrophic consequence of exchange insolvency: customer deposits (assets the exchange held but didn’t own) had been used to fund Alameda Research’s losses, leaving FTX with $8 billion more in customer liabilities than recoverable assets — classically insolvent.

For equity traders, monitoring solvency metrics alongside valuation metrics identifies the crucial distinction between a “cheap” stock and a “value trap.” A company with a low price-to-book ratio might be cheap because the market has mispriced it (genuine value opportunity) or because its assets are worth far less than the book value suggests and its debt load will eventually prove unsustainable (value trap). Debt-to-equity ratios, interest coverage, and free cash flow relative to debt service requirements distinguish these scenarios.

In crypto, proof-of-reserves initiatives attempt to apply solvency verification to exchanges — publicly verifying that customer deposit liabilities are backed by equivalent or greater assets held in verifiable on-chain wallets. After FTX’s collapse, exchanges including Binance, Kraken, and Coinbase published proof-of-reserves attestations. While these don’t provide complete solvency assurance (liabilities beyond customer deposits aren’t fully captured), they represent a meaningful step toward bringing solvency transparency to an industry that previously operated opaquely.

Key Takeaways

• Solvency measures whether total assets exceed total liabilities at a fundamental level — distinct from liquidity, which measures immediate cash availability; a company can be solvent but illiquid (profitable business, temporary cash crunch) or liquid but eventually insolvent (cash available now, structural losses eroding equity).
• FTX was insolvent — customer deposit liabilities exceeded recoverable assets by approximately $8 billion — because customer funds had been used to cover Alameda Research’s trading losses, creating a liability mismatch that a basic solvency analysis of the balance sheet would have revealed if transparent disclosures had been required.
• An interest coverage ratio below 1.5× signals solvency risk — when operating earnings are barely sufficient to cover interest payments, any revenue decline, cost increase, or rate rise can push the ratio below 1.0×, where the company cannot service its debt from earnings alone and must rely on asset sales or new financing to remain solvent.
• Proof-of-reserves attestations (Binance, Kraken, Coinbase post-FTX) attempt to verify that exchange customer liabilities are matched by on-chain assets — a solvency verification mechanism that, while incomplete (liabilities beyond customer deposits aren’t fully captured), provides more assurance than the industry’s prior opacity.
• The 2008 financial crisis was fundamentally a solvency crisis — banks’ mortgage-backed securities assets were worth less than their face value, leaving institutions with total assets below total liabilities — but was initially misdiagnosed as a liquidity crisis, delaying the recapitalisation needed to address the structural problem.
