Perpetual futures have become a dominant trading instrument in the crypto derivatives market. Their structure allows traders to maintain leveraged positions indefinitely without worrying about contract expiries. However, one critical component that often gets overlooked by beginners is the funding rate. This mechanism plays a vital role in maintaining price stability between the perpetual contract and its underlying spot market.
Understanding how funding rates work is essential for anyone participating in perpetual futures trading. It not only affects profitability but can also impact trade timing, strategy execution, and overall market sentiment. This article provides a deep dive into funding rates, how they are calculated, and why they matter in today’s volatile crypto markets.
What Are Perpetual Futures?
Perpetual futures are a type of derivative contract that allows traders to speculate on the price movement of a cryptocurrency without owning the underlying asset. Unlike traditional futures, they do not have an expiration date. This means positions can be held indefinitely, as long as the trader maintains sufficient margin.
These contracts are widely used on platforms like MEXC, which supports hundreds of trading pairs and offers high leverage options up to 500x. The popularity of perpetual futures has surged in recent years due to their flexibility, liquidity, and the opportunity for both long and short strategies in any market condition.
How Funding Rates Keep Prices in Check
Since perpetual futures don’t expire, there needs to be a mechanism that ensures their price remains close to the spot market. That’s where funding rates come in.
Funding is a periodic payment exchanged between traders who are long and those who are short. The direction of payment depends on the premium or discount of the perpetual price compared to the spot price:
- If the perpetual contract is trading higher than the spot price, long positions pay short positions.
- If the perpetual contract is below the spot price, short positions pay long positions.
This system incentivizes traders to take positions that bring the contract price closer to the underlying asset.
Funding Rate Calculations on Leading Platforms
Funding rates vary across exchanges but are generally calculated using two components:
- Interest Rate: A fixed base rate, often set at 0.01% per funding interval
- Premium Index: A floating component reflecting the difference between the perpetual and spot prices
On MEXC, funding rates are updated multiple times per day, with clear historical data provided for every contract. Traders can check upcoming and past rates directly on the platform to plan their entries and exits strategically.
Practical Example: SOL/USDT and SUI/USDT
Suppose you’re trading SOLUSDT and the perpetual contract trades at a consistent premium to the spot market. This might indicate strong bullish sentiment, but it also means long traders are paying high funding rates. On the other hand, SUIUSDT might be trading below spot, offering a potential funding income for long positions.
Understanding these dynamics can help traders align with market sentiment or even adopt contrarian strategies based on overextended funding patterns.
Why Funding Rates Matter in 2025
The importance of funding rates has grown in 2025 due to increased retail participation, high volatility in altcoin markets, and the rise of AI-driven trading strategies that exploit inefficiencies in funding.
Key reasons why funding rates are now more influential than ever:
- High Leverage Usage: With MEXC offering up to 500x leverage, even small funding rates can significantly impact net returns.
- Increased Trading Volume: Perpetual futures dominate over 70% of total crypto derivatives volume, making funding costs a major part of trading expenses.
- Algorithmic Arbitrage: Many bots now monitor funding rate anomalies and execute trades to capture spread profits.
Impact on Profitability and Risk
Funding rates can either add to or eat into your profits. Here’s how they affect traders:
- Positive for shorts: In a bullish market, shorts may receive funding, providing a passive income stream.
- Negative for longs: Long positions must pay funding, reducing net gains.
- Impact on timing: Traders may delay entries until after funding intervals to minimize cost.
Risk Disclaimer
High-leverage futures trading involves substantial risk. Traders should understand funding rate mechanics thoroughly and implement proper risk management. This article is for educational purposes only and does not constitute investment advice.

- Funding Arbitrage: Going long on one exchange and short on another with different funding rates
- Short-term swing trading: Timing entries to avoid paying high funding fees
- Funding as a Sentiment Indicator: Extreme positive rates may signal overbought conditions

Common Funding Rate Myths
“Funding always benefits shorts”
False. While bullish conditions often result in longs paying shorts, market sentiment changes rapidly. Shorts can end up paying during bearish recoveries.
“Funding rates are negligible”
Not true when using high leverage. A 0.01% funding rate every 8 hours adds up significantly over time, especially on large positions.
“Avoiding funding means no cost”
Skipping funding intervals might save on fees, but it can also lead to missed opportunities. Balance timing with market analysis.
