Choosing the right centralized exchange (CEX) for crypto lending can be overwhelming—complex rules, varying interest models, and hidden risks make it easy to misstep. This guide breaks down the key features of leading platforms like Binance, OKX, and Bybit, helping you navigate their lending mechanisms with confidence. Whether you're a borrower or lender, understanding these nuances is critical to maximizing returns and avoiding costly mistakes.
Understanding CEX Lending: Core Concepts
Crypto lending on centralized exchanges allows users to borrow digital assets by locking up collateral. However, not all platforms operate the same way. Key differences lie in collateral usability, interest rate models, liquidation mechanisms, and flexibility in portfolio management.
The three major players—Binance, OKX, and Bybit—each offer distinct advantages depending on your strategy. Let’s dive into how each platform structures its lending products.

Binance Flexible Lending: Borrower-Friendly with Yield-Preserving Collateral
Collateral Requirements
Binance requires users to pledge assets from its Protected Savings program as collateral. This includes 137 supported cryptocurrencies such as USDT. If your current holdings aren’t sufficient, you can convert spot assets into eligible savings products before using them as collateral.
One unique feature: your collateral continues earning yield while pledged. This applies to both real-time and tiered annual percentage yields (APY), except for BNB, which loses Launchpool rewards during use.
Borrowing Mechanics
You can borrow against 218 different assets, each under a separate “collateral-borrow” pair. For example:
- USDT collateral → borrow ETH
- USDT collateral → borrow BTC
Each position is isolated, meaning risk and margin requirements are calculated independently. This isolation protects other positions if one gets liquidated.
There’s no fixed loan term—as long as your loan-to-value (LTV) ratio stays below thresholds and supported assets remain available, you can hold indefinitely.
Initial LTV ratios vary by asset but are typically set at 78% (i.e., $100 in collateral allows up to $78 in borrowing).
Liquidation Rules
If any position reaches a 90% LTV, or if the outstanding loan drops below $200, full liquidation occurs. The platform uses equivalent collateral to repay the debt and charges a 2% liquidation fee on the borrowed amount.
Liquidations are triggered per-position, so only the affected pair is closed.
Interest Structure
Interest rates update every minute and are added directly to your outstanding balance. While Binance doesn’t disclose exact calculation methods, higher demand generally increases borrowing costs. When borrowing limits are reached, redemptions pause until more liquidity becomes available—this was central to past disputes involving tokens like CYBER.
Despite this, Binance promotes transparency through its Protected Savings Product Guide, noting that temporary redemption delays may occur under high demand.
Key Benefit: Net Effective Rate Calculation
Because collateral keeps earning yield, borrowers benefit from a lower net borrowing cost. For instance:
- WLD borrowing rate: 24.06%
- Minus ETH yield earned on collateral
- Net effective rate: ~22.9% at 78% LTV
Note: The displayed net APY assumes full utilization; partial borrowing requires manual recalculations.
OKX Flexible Lending: High Flexibility Favors Depositors
Collateral Setup
OKX supports 149 collateral types, including USDT. Unlike Binance, there’s no additional yield on pledged assets—they’re locked solely for borrowing purposes.
Borrowing Flexibility
One of OKX’s standout features is the ability to create multi-collateral borrowing positions. Users can combine multiple assets (e.g., BTC + ORDI + BCH) into a single loan bucket, borrowing any of 127 supported assets.
This setup allows dynamic rebalancing within safety limits—ideal for managing diversified portfolios efficiently.
Initial LTV is typically 70%, slightly more conservative than competitors.
Liquidation Mechanism
OKX uses a sophisticated formula:
Liquidation LTV = (Collateral Value × Discount Factor – Loan Value × Maintenance Margin – Penalty Fee) / Collateral Value
Most assets have a 98.5% liquidation threshold, but the discount factor varies widely:
- BTC, ETH, USDT, USDC: 0.9–1.0 (depending on amount)
- Low-cap altcoins (e.g., NOT, 1INCH): 0.5 up to $50K; **0 above $50K**
This means some altcoins have a hard cap of $50,000 in borrowing power and no scalability beyond that.
Crucially, after liquidation, any remaining funds go into the platform risk reserve fund—not back to the user—highlighting a key risk for over-leveraged borrowers.

Interest Model: Market-Matched Rates
OKX updates rates hourly based on supply and demand dynamics via its "Savings" product. Here’s how it works:
- User A offers 1,000 USDT at 1% minimum rate
- User B offers 1,000 USDT at 10% minimum rate
- A borrower takes 1,500 USDT → gets 1,000 at 1%, 500 at 10%
This creates opportunities for "interest bursts"—depositors who set higher minimums may earn outsized returns when demand spikes.
Unique Feature: Automatic Coin Swap System
When platform-wide borrowing reaches 100% of available deposits, OKX triggers an automated mechanism:
- Users are ranked by borrowing size
- Top borrowers face forced asset swaps to reduce systemic risk
Unlike Binance’s passive approach (raising rates), OKX actively manages risk exposure. However, the overall borrowing ratio isn’t public—users receive email alerts instead.
This system ensures depositors retain instant withdrawal access, making OKX particularly attractive for savers seeking liquidity and stability.
Bybit Pledge-to-Borrow: Simplicity with High Leverage
Collateral & Borrowing Pairs
Bybit supports 153 collateral assets and 157 borrowable ones. Like Binance, it uses isolated “collateral-borrow” pairs—each tracked separately.
No yield is generated on pledged assets.
Lending Terms
- Initial LTV: 80% (higher than most)
- Liquidation LTV: 95% (or 93% for select pairs)
This high threshold gives borrowers more breathing room but increases potential losses during volatility.
Liquidation Process
Upon liquidation:
- Full repayment using collateral
- 2% penalty deducted from remaining assets
- Any leftover funds returned to the designated account
Transparent and straightforward—but less forgiving than systems with partial deleveraging.
Interest Calculation
Rates fluctuate hourly based on market conditions. Interest accrues hourly until repayment or liquidation.
No fixed maturity dates allow indefinite holding—similar to Binance and OKX.

Frequently Asked Questions (FAQ)
Q: Can I lose more than my collateral in CEX lending?
A: Generally no—liquidation closes the position using only pledged assets. However, if price movement is extreme, slippage could lead to minor shortfalls (covered by platform funds). Always monitor health ratios closely.
Q: Why does OKX send funds to a risk reserve after liquidation?
A: To cover potential insolvency in fast-moving markets. It discourages excessive leverage and protects the broader user base from systemic collapse.
Q: Is Binance’s yield-on-collateral guaranteed?
A: The yield comes from its Protected Savings program, which promises capital protection under normal conditions. However, regulatory changes or extreme market events could impact availability.
Q: How do I avoid unexpected liquidations?
A: Use conservative LTVs (e.g., stay below 70%), enable price alerts, and avoid relying solely on platform UI metrics—calculate net costs manually when necessary.
Q: Which platform is best for long-term borrowers?
A: Binance suits long-term borrowers due to perpetual terms and yield offsetting interest costs. Just ensure redemption limits won’t affect your strategy.
Q: Are stablecoins always safe collateral?
A: Not necessarily. Regulatory shifts (e.g., EU MiCA rules) may restrict certain stablecoins like USDT in regions like the EEA—even if technically supported elsewhere.
Final Thoughts
Choosing a CEX lending platform isn’t just about interest rates—it’s about aligning product design with your financial goals. Binance favors borrowers through yield preservation; OKX prioritizes depositor safety with smart automation; Bybit delivers simplicity with aggressive leverage options.
Understanding these differences helps you avoid costly surprises and optimize your crypto finance strategy in 2025 and beyond.
