How to Use OKX Collateralized Loans? Costs, Liquidation, and Releasing Collateral

OKX

03 October 2026

The cost and risk of OKX collateralized loans ultimately depend on two external variables you cannot fully control: real-time interest rate fluctuations and the platform's overall borrowing rate. The initial loan-to-value ratio (LTV) you see is only the entry threshold. The real risk line is the forced liquidation LTV (usually 98.5%). Once that is reached, your collateral will be sold by the system to repay the debt, and any remaining funds are typically not returned.

Cost: Interest Rates Change Every Hour and Can "Explode"

OKX flexible loan interest rates are not a fixed annualized rate. They refresh every hour based on market matching conditions. The rate is determined by the order rates from Earn users and borrowing demand. This means when market borrowing demand is high, the interest rate can spike quickly. The loan agreement clearly states that the interest rate "may be as high as 100% APR in certain circumstances."

Interest is accrued and deducted every hour, so you only pay for the actual time you use the loan. The advantage of this mechanism is that you can borrow and repay anytime with no fixed term. The trade-off is that the cost is unpredictable, especially during periods of high market volatility when many people are borrowing.

LTV and Liquidation: Look at the Discount Rate First, Then the Liquidation Line

OKX's initial LTV is usually around 70%, meaning you need to pledge assets worth 100 USDT to borrow 70 USDT. But what determines your risk level is not the initial LTV, but the discount rate of your collateral.

Different coins have very different discount rates. BTC, ETH, and USDT have higher discount rates, while many altcoins may have a discount rate as low as 0.5. Some tokens even have a discount rate of 0 once the loan amount exceeds 50,000 USD, meaning those coins cannot be used to support borrowing at all.

The forced liquidation LTV is basically 98.5%. When the value of your collateral (after discount adjustment) cannot cover the loan value plus maintenance margin and liquidation fees, liquidation will be triggered. After forced liquidation, remaining funds will go to the platform's risk reserve and will not be returned.

An Easily Overlooked Risk: Platform-Wide Borrowing Rate

Besides your own LTV, OKX has a platform-level auto-conversion mechanism. When the total borrowed amount divided by total deposited amount for a specific coin reaches 100%, the system will, in order to reduce platform-wide risk, sort users by their borrowed amount from largest to smallest and prioritize "auto-conversion" for users with the largest borrow amounts. This means the system will sell your collateral to repay the loan for that coin.

This means that even if your own LTV is healthy, you could still be forced to partially repay if the entire platform runs out of that coin for lending. This "platform borrowing rate" data is not public. Users can only receive risk alerts and liquidation tier notifications via email.

How to Borrow and Release Collateral

To borrow: Go to "Finance" > "Borrow" on the app or website, select the coin you want to borrow, add collateral assets, confirm the LTV and interest rate, and submit. The borrowed funds will go into your funding account or trading account and can be transferred or withdrawn freely.

To release collateral: After repaying the loan, your collateral will be automatically released. But there is one detail: if your collateral includes coins with lower discount rates, the remaining portion may not be immediately transferable. You can manually reduce collateral multiple times in the loan details page until everything is released.

Repaying with collateral: OKX supports repaying directly with collateral assets. The system will sell your collateral for USDT via IOC orders, then use that USDT to buy back the borrowed coin. This process incurs trading fees and slippage, and may result in "overbuying" — meaning the bought-back amount of the borrowed coin slightly exceeds the actual debt, and the remaining portion will stay in your account.
