In a strategic move to strengthen market stability, improve liquidity, and optimize the user trading experience, OKX will implement a series of adjustments to its portfolio margin parameters in early 2025. These updates target key risk metrics—MR1 (spot shock), MR4 (basis risk), MR6 (extreme move), MR7 (minimum charge), and MR9 (stablecoin depegging risk)—to better reflect current market dynamics and reduce systemic exposure during periods of high volatility.
The changes are designed to align with evolving trading patterns, enhance capital efficiency, and ensure robust risk controls across spot, futures, and cross-currency hedging positions.
Understanding Portfolio Margin and Its Importance
Portfolio margining allows traders to use their overall portfolio value as collateral, rather than isolating margin per position. This method increases capital efficiency by accounting for offsetting positions and diversification benefits. However, it requires precise risk modeling to prevent under-collateralization during sharp market moves.
OKX’s updated parameters refine these models, adjusting thresholds for extreme price swings, spot volatility shocks, and stablecoin peg deviations. The goal is to maintain platform resilience while supporting active, sophisticated trading strategies.

MR1: Spot Shock Adjustments – Smoother Volatility Buffering
The MR1 parameter measures potential spot price shocks across major cryptocurrencies. The upcoming adjustment reduces maximum assumed price moves for top-tier assets, reflecting improved market depth and reduced historical volatility.
Before Adjustment
- BTC & ETH: ±0%, 5%, 10%, 15%
- Mid-cap assets (e.g., LTC, XRP, ADA): ±0%, 7%, 14%, 20%
- Others: ±0%, 8%, 16%, 25%
Updated Parameters (Effective Jan 6, 2025)
- BTC & ETH: ±0%, 4%, 8%, 12%
- Mid-cap assets: ±0%, 6%, 12%, 18%
- Others: Unchanged at ±0%, 8%, 16%, 25%
This reduction signals increased confidence in BTC and ETH price stability, allowing more efficient margin usage for large-cap positions. Traders can expect lower forced liquidations during moderate swings.
MR6: Extreme Move Scenarios – Lowering Tail Risk Exposure
MR6 defines the maximum assumed single-day price movement under extreme market stress. The revised values indicate a recalibration of tail risk assumptions.
Previous Levels
- BTC & ETH: ±30%
- High-volatility altcoins (e.g., DOGE, SHIB, PEPE): ±40%
- All others: ±50%
New Thresholds (Effective Jan 6, 2025)
- BTC & ETH: ±24% (↓20%)
- Altcoins: ±36% (↓10%)
- Others: Remains at ±50%
By lowering these caps, OKX reduces over-collateralization during normal conditions while still protecting against black swan events. This fine-tuning enhances leverage availability without compromising safety.
MR4: Basis Risk Reduction – Tighter Futures-Spot Alignment
MR4 quantifies annualized volatility risk between futures and spot prices (basis risk). A lower value means tighter expected divergence.
Prior Annualized Move Risk
- BTC & ETH: 7.50%
- SOL, BNB, XRP, etc.: 22.50%
- Other tokens: 45.00%
Updated Risk Assumptions
- BTC & ETH: 5.00%
- Mid-tier assets: 15.00%
- Others: 30.00%
These reductions reflect maturing derivatives markets and tighter arbitrage mechanisms. Traders benefit from reduced margin requirements on hedged futures positions, improving yield strategy efficiency.

MR7: Minimum Charge Structure Overhaul – Scaling with Volume
MR7 determines the base fee multiplier applied to large portfolios. The updated tier system significantly raises thresholds before higher multipliers apply, favoring institutional-scale traders.
Before (BTC & ETH)
| Tier | USD Range | Multiplier |
|---|---|---|
| 1 | [0–10K] | 1x |
| 2 | (10K–70K] | 2x |
| ... | ... | ... |
| 7 | (>700K) | 12x |
After Adjustment (Effective Jan 15, 2025)
| Tier | USD Range | Multiplier |
|---|---|---|
| 1 | [0–250K] | 1x |
| 2 | (250K–500K] | 2x |
| 3 | (500K–1M] | 4x |
| 4 | (1M–2M] | 6x |
| 5 | (2M–3M] | 8x |
| 6 | (3M–4M] | 10x |
| 7 | (>4M) | 12x |
This expansion reduces friction for large-volume traders, delaying the point at which escalating fees kick in. It supports scalability and long-term portfolio growth.
MR9: Stablecoin Depegging Risk – Expanded Tiers for Precision
MR9 assesses risk when stablecoins deviate from their $1 peg. The update retains percentage-based risk charges but expands volume tiers for finer risk grading.
Key Changes in USDT/USD, USDT/USDC, and USDC/USD Models:
- Tier 4: Expanded from ≤$20M → ≤$30M
- New Tier 6: $50M–$80M
- New Tier 7: $80M–$120M
- Tier 8 Threshold: Raised from $50M+ → $120M+
Risk percentages per depeg level remain unchanged:
- At USDT = $0.95: Risk charge ranges from 5% to 17%, depending on volume tier
- Below $0.80: Flat 40% charge across all tiers
The expanded structure allows more granular margin calculation for large stablecoin hedges, improving capital efficiency for arbitrageurs and market makers.
