Key Takeaways

Rehypothecation occurs when a lender uses the collateral pledged by its users to secure its own loans or generate yield with third parties.

While it increases liquidity and allows platforms to offer high interest rates, it also creates a complex chain of financial dependency.

The main risk of rehypothecation happens when a third-party borrower defaults, causing the primary lender to become insolvent and leaving depositors unable to withdraw their funds.

Investors can mitigate risks through self-custody. It’s also important to understand the terms of service and recognize the trade-off between high yield and security.

Introduction

Earning passive income through crypto lending platforms has become a popular strategy. Users deposit their digital assets to earn an annual percentage yield (APY), much like a savings account. However, unlike traditional banking, the mechanisms generating these yields often involve a practice known as rehypothecation.

While rehypothecation is a standard practice in traditional finance (TradFi), its application in the crypto sector operates with fewer regulations. Understanding this concept is important for any investor entrusting their assets to a centralized exchange (CEX) or lending platform.

Understanding Hypothecation vs. Rehypothecation

Hypothecation is the act of pledging an asset as collateral to secure a loan. For example, when you take out a mortgage, your house is hypothecated to the bank. You retain ownership, but the bank has a claim on it if you default. In crypto, this happens when you lock bitcoin to mint a stablecoin or take a cash loan.

Rehypothecation occurs when the entity holding your collateral (the bank or crypto platform) takes those pledged assets and uses them for their own purposes, usually pledging them as collateral for their own trading or lending them to a third party. In other words, you lend your money to a platform, and the platform lends your money to someone else.

How Rehypothecation Works in Crypto

Rehypothecation is the engine behind many high-yield crypto accounts. Here is the typical flow of funds:

Deposit: Let’s suppose you deposit 1 BTC into a centralized lending platform offering 5% APY.

Re-lending: The platform takes your 1 BTC and lends it to an institutional borrower (such as a hedge fund or market maker) at 8% interest.

The spread: The platform pays you 5% and keeps the 3% difference as profit.

From the platform's perspective, this maximizes capital efficiency. However, it means your bitcoin is no longer sitting in the platform's cold storage; it’s in the hands of a third party.

The Core Risks of Rehypothecation

When assets are rehypothecated, the depositor is exposed to "counterparty risk." This creates a house-of-cards scenario where the failure of one entity can trigger a collapse of others.

1. Counterparty insolvency

If the hedge fund (Borrower B) makes bad trades and loses the BTC they borrowed from your platform (Lender A), they cannot repay the loan. Consequently, Lender A now has a hole in its balance sheet and cannot repay you. You are relying on the financial health of entities you don’t really know.

2. Bank run

In times of market volatility, users often rush to withdraw their funds simultaneously. If a platform has rehypothecated a large percentage of user funds into illiquid investments or long-term loans, it likely won’t have the liquid cash to honor withdrawal requests. This usually leads to a freeze on withdrawals and potential bankruptcy.

3. Unsecured creditor status

In traditional brokerage accounts (like in the US), rehypothecation is capped (usually at 140% of the loan balance) and insured (SIPC). In crypto, regulations are still evolving. Terms of Service for many lending platforms state that upon deposit, you transfer ownership of the assets to them. In the event of bankruptcy, depositors are often treated as unsecured creditors, meaning they are last in line to be repaid.

Examples: The 2022 Liquidity Crisis

The risks of rehypothecation became a reality during the crypto market crash of 2022. Several major platforms collapsed due to aggressive rehypothecation strategies:

Celsius Network: The platform rehypothecated user funds into high-risk DeFi protocols and loans. When the market turned, they could not recall liquidity fast enough to meet user withdrawals.

Voyager Digital: Voyager lent hundreds of millions of dollars of user assets to a single hedge fund, Three Arrows Capital (3AC). When 3AC defaulted due to its own trading losses, Voyager became insolvent.

CeFi vs. DeFi Rehypothecation

It’s important to distinguish between centralized and decentralized finance. CeFi operations are more opaque. Users often deposit funds into a "black box" without knowing who the counterparty is or how much leverage is being used.

DeFi rehypothecation exists (often via liquid staking or wrapping), but it is generally transparent. Users can verify on the blockchain where their assets are deployed. However, DeFi introduces smart contract risk, where bugs in the code can lead to loss of funds.

How to Mitigate Rehypothecation Risk

Self-custody: The most effective way to avoid rehypothecation risk is to hold your assets in a non-custodial crypto wallet. If you hold the private keys, the assets can’t be lent out.

Read the fine print: Before using a centralized lender, read the Terms of Service. Look for clauses regarding "transfer of title" or the platform's right to "pledge, re-pledge, or hypothecate" your assets.

Assess the yield: Be skeptical of high yields. If a platform offers significantly higher interest than the market average, it often signals they are engaging in riskier rehypothecation strategies to generate that return.

Segregated accounts: While rare in retail, some institutional custodians offer segregated wallets where client assets aren’t mixed with the firm’s assets.

Closing Thoughts

Rehypothecation is a double-edged sword. On one hand, it provides the liquidity necessary for markets to function and allows holders to earn yield on idle assets. On the other hand, it introduces systemic risks that can lead to total loss of funds during bear markets.

For the individual investor, the choice comes down to risk tolerance. Remember that old saying: "not your keys, not your coins". Keeping control over your funds provides total protection against rehypothecation risk.
