Since last year, several centralized exchanges have had disputes over lending products, with the parties claiming that they “suffered huge losses” due to unclear terms. In fact, the lending products of major centralized exchanges are not simply depositing collateral and lending it out, but have many “special” regulations.

To this end, Odaily Planet Daily will summarize and explain the lending rules of Binance, OKX, and Bybit in this article to help readers understand the product details.

Binance Demand Loans

Collateral

Users can only pledge assets that have been subscribed to the principal-guaranteed coin-earning current products as collateral, including 137 currencies including USDT . If the principal-guaranteed coin-earning collateral is not enough to guarantee the required loan amount, users can also use the digital assets in the spot account to subscribe to the principal-guaranteed coin-earning current products and then use them as collateral.

Borrowing Details

Separate positions : There are 218 types of assets that users can borrow. Each collateral-loan pair can open a separate loan position . For example, one position is USDT collateral + ETH loan, and the other position is USDT collateral + BTC loan. Each collateral-loan pair is independent, and its pledge rate, margin call and forced liquidation pledge rate are calculated separately.

No active liquidation for borrowed coins : Binance current borrowing is an unlimited-term product. As long as this product supports borrowed coins and collateral digital assets, and does not exceed the corresponding pledge ratio, users can hold positions indefinitely.

Collateralization rate : Depending on the collateralized currency, the initial collateralization rate varies, but most are 78% (meaning that a collateral worth $100 can borrow a maximum of $78 in assets).

Liquidation Rules

If any currency reaches the maximum forced liquidation rate of 90% , or the outstanding loan value is less than $200 , a full forced liquidation will be carried out. All loans will be repaid through the equivalent collateral of the loan position. If a forced liquidation occurs, the platform will charge 2% of the loan amount as a forced liquidation fee .

Borrowing interest

The interest on borrowed coins can be checked on the Binance lending page 和 is updated every minute . It is worth noting that Binance has not announced the calculation method of borrowing interest for each currency, but in general, the higher the overall pledge rate of a token, the higher the interest. When the loan reaches a certain limit, the depositor will not be able to redeem it, but the interest will also rise to a certain level to encourage the borrower to repay as soon as possible.

(Odaily Note: This clause is also the root cause of the previous CYBER controversy . Binance emphasized in the Getting Started Guide to Binance’s Principal Guaranteed Coins Current Product that “ if there are too many redemption requests for a certain currency, it may still cause a temporary shortage of available balance. In this case, redemption will return to normal when the borrower repays or other users provide additional liquidity .”)

After the loan order is successful, interest will be calculated every minute, and the interest generated every minute will be added to the total outstanding loan amount.

Special Terms

Due to the influence of the EUs crypto asset market supervision law, the European Economic Area (EEA) cannot lend unregulated stablecoins such as USDT, FDUSD, etc. For details, please see the English version of the lending rules .

After the digital assets used to subscribe to the principal-guaranteed coin-earning current account products are pledged to Binance current account borrowing, the real-time annualized income and tiered annualized income of the principal-guaranteed coin-earning current account products will continue to be obtained, but BNB will no longer enjoy the Launchpool income. As shown in the figure below, the original loan interest rate of WLD is 24.06%. After deducting the current account income of ETH, the loan is made according to the 78% pledge rate, and the net loan interest rate is 22.9%.

(Odaily Note: The net annualized interest rate displayed on the interface is calculated according to the initial pledge rate and will not change with the loan amount . Users who do not borrow the full amount need to calculate the annualized interest rate separately.)

OKX Demand Loan

Collateral

There are a total of 149 currencies, including USDT , and the collateral is simply pledged without any other benefits or requirements.

Borrowing Details

Mode selection: There are 127 types of assets that users can borrow, and they can freely combine to establish multi-collateral-loan pairs . As shown in the figure below, BTC+ORDI+BCH are used as collateral, and the borrower can choose from 127 tokens. When a loan position exists, the collateral can be freely adjusted within the safety line .

Pledge rate: OKXs initial pledge rate is relatively low, basically 70%.

Liquidation Rules

OKXs forced liquidation pledge rate is calculated as = (collateral value × currency discount rate – loan value × maintenance margin rate – forced liquidation fee) / collateral value. The forced liquidation pledge rate is basically 98.5%, but the discount rate of each token varies greatly . The highest is BTC, ETH, USDT, and USDC, and the discount rate varies between 0.9-1 depending on the amount. The lowest is a series of altcoins such as NOT, 1INCH, ACE, etc. The discount rate is 0.5 for less than 50,000 US dollars, and the discount rate is 0 for more than 50,000, which means that the borrowing limit is only half of that of BTC and other currencies, and the maximum borrowing amount is 50,000 US dollars.

In addition, it should be noted that after the forced liquidation of the current loan , the remaining funds will enter the platform risk reserve to cover possible losses from liquidation and will not be returned.

Borrowing interest

The interest rate of OKX current loan is refreshed every hour, and interest is deducted every hour. The interest rate mechanism is relatively special, and the market interest rate is generated by matching the interest rate posted by Yubibao users with the loan amount. For example:

User A deposits 1000 USDT and sets the minimum lending rate to 1%. User B deposits 1000 USDT and sets the minimum lending rate to 10%. If a user borrows 1500 USDT on the platform, then user A will be fully matched, and user Bs 500 USDT will be lent at an interest rate of 10%, with no interest on the remaining part. Therefore, there is a possibility of critical returns on borrowed coins on the OKX platform.

Special Terms

In addition to the healthy borrowing and lending ratio of users, OKX also has an automatic currency exchange mechanism for borrowing . When the platforms borrowing amount/deposit amount reaches 100%, in order to reduce the risk of all borrowing users on the platform as soon as possible, users will be graded from large to small according to their borrowing amount. The group of users with the highest borrowing amount will be given priority to be automatically exchanged by the system. In short, whether a users loan will be liquidated is also related to the overall lending rate in the market .

(Odaily Note: The official document is Automatic Currency Exchange Rules .)

The above rules correspond to OKXs depositors being able to deposit and withdraw at any time, which is completely different from Binances model of triggering the upper limit and forcing borrowers to repay through high interest rates. According to the official announcement, this model is not expected to be adjusted in the near future.

Therefore, for borrowers, in addition to the healthy ratio of their own positions, they also need to pay attention to the overall lending rate of the market. However, in order to prevent attackers from maliciously attacking based on this data, the overall lending rate of the market will not be made public. Users will receive risk warnings and liquidation echelons via email.

Bybit pledge loan (simple version of loan)

Collateral

There are a total of 153 currencies, including USDT , and the collateral is simply pledged without any other benefits or requirements.

Borrowing Details

Separate positions: There are 157 types of assets that users can borrow , and each collateral-loan pair can open a separate loan position, which is basically the same as the model adopted by Binance.

Pledge rate: Bybits initial pledge rate is 80%, and the forced liquidation pledge rate is 95% (a few are 93%), which is much higher than other platforms.

Liquidation Rules

The users collateral assets will be used to automatically repay the full amount, and a 2% liquidation fee will be charged. The liquidation fee will be deducted from the collateral amount, and any remaining collateral after full repayment will be returned to the account that the user previously selected for collateral deduction.

Borrowing interest

There is no fixed repayment date for demand loans, and the interest rate is not fixed. It fluctuates every hour according to market conditions, and interest will be calculated on an hourly basis until the loan is repaid or forced liquidation is triggered.

综上所述

Most DEXs adopt the method of earning interest on deposited coins. Once the loan reaches the upper limit, it cannot be withdrawn and the interest rate is greatly increased, which encourages borrowers to repay the loan. This method is similar to Binances solution.

Binance and OKX have introduced more complex lending rules than other exchanges. In the event of an extreme surge in prices and the platform being fully borrowed, Binances depositors will be unable to withdraw and sell their coins, which is relatively beneficial to borrowers. OKX has greater flexibility and combinability, and is relatively beneficial to depositors.

Some readers may remember former ECB President Draghi’s famous “whatever it takes” declaration during the Euro crisis, which marked an important historical turning point when the central bank effectively provided a floor for the market and pushed investors into a years-long “risk-on” mode.
