Funding rate is a crucial concept in cryptocurrency derivatives trading—especially for those diving into perpetual futures contracts. If you're new to crypto trading, this mechanism might be unfamiliar, especially if your experience lies in traditional markets like stock index futures. Unlike time-limited instruments such as Taiwan Index Futures, which settle monthly, perpetual contracts never expire. This unique feature necessitates a balancing system: the funding rate.
This article explains what funding rates are, how they work, how to interpret them, and their implications—especially when negative. We’ll use Binance as a real-world example to illustrate these dynamics clearly.
Understanding Funding Rate in Crypto Trading
At its core, funding rate is a balancing mechanism designed to keep the price of perpetual futures contracts closely aligned with the underlying spot market price.
In traditional futures markets, the contract price naturally converges with the spot price as the settlement date approaches. Arbitrageurs quickly jump in when prices diverge—buying low on one side and selling high on the other—locking in risk-free profits before expiry. This constant arbitrage activity keeps prices in check.
But perpetual contracts have no expiration date, meaning there's no automatic convergence. Without intervention, futures prices could drift significantly from spot values during periods of extreme sentiment.
That’s where funding rates come in.

The funding rate ensures alignment by transferring funds between long and short positions every few hours (typically every 8 hours on most platforms). When the funding rate is positive, longs pay shorts. When it’s negative, shorts pay longs. This incentivizes traders to step in when the market becomes imbalanced, effectively pulling the contract price back toward fair value.
How Is Funding Rate Calculated?
Each exchange uses its own formula, but the logic remains consistent: measure the premium or discount of the futures price relative to spot, then adjust accordingly.
On Binance, the funding rate (F) is calculated as:
F = P + Clamp(I - P, 0.05%, -0.05%)Where:
- P = Average Premium Index (updated every 5 seconds)
- I = Interest Rate (typically 0.01%)
- Clamp function limits the deviation to ±0.05%
This means that if the premium index stays within a tight range (between -0.04% and 0.06%), the funding rate will remain close to the base interest rate.
The actual amount paid or received depends on three factors:
- Mark price of the asset
- Number of contracts held
- Current funding rate
Funding Amount = Mark Price × Contract Quantity × Funding Rate
For instance, holding $10,000 worth of long positions with a 0.01% funding rate means paying $1 every funding interval—if you hold through that period.
Most exchanges, including Binance, apply funding at fixed times daily—often at 00:00, 08:00, and 16:00 UTC+8. Close your position before the next cycle? You avoid the charge or miss out on collection.
Where Can You Check Funding Rates?
On Binance
Navigate to any perpetual futures pair—the funding rate is displayed prominently at the top of the trading interface. You’ll see:
- Current funding rate (e.g., -0.0028%)
- Countdown to next payment
A positive number indicates longs are paying shorts, often signaling bullish momentum. A negative value shows shorts are paying longs, reflecting bearish dominance.
On Coinglass
Platforms like Coinglass offer deeper insights, showing historical trends and cross-exchange comparisons. Traders use these tools to spot potential funding arbitrage opportunities—capitalizing on unusually high or sustained funding rates.
Using Funding Rate Strategically: Cash-Futures Arbitrage
One popular strategy leveraging funding rates is cash-futures arbitrage (also known as spot-futures arbitrage).
Since funding rates are typically positive over time—reflecting persistent bullish bias—traders can:
- Go short on perpetual futures
- Hold an equivalent long position in spot
These offsetting positions neutralize directional risk while allowing the trader to collect regular funding payments from longs.
Some platforms even offer automated bots to execute this strategy continuously, reducing manual effort.

However, this approach carries risk: if the funding rate turns negative, the short futures position starts paying instead of receiving. In strong downtrends, this can erode profits or create losses.
Hence, many experienced traders avoid cash-futures arbitrage during bear markets—or reverse it: going long on futures and shorting spot via leveraged tokens or margin trading.
Still, due to the relative rarity of prolonged negative funding, some argue it's more efficient to simply take directional short positions rather than manage complex hedges.
What Does a Negative Funding Rate Mean?
A negative funding rate signals that shorts dominate the market. More traders are betting on price declines, pushing the futures price below fair value. To restore equilibrium, shorts must pay longs—a cost for maintaining bearish exposure.
Extended periods of negative funding often reflect deep pessimism. While tempting for contrarian investors ("this might be the bottom!"), chasing bottoms based solely on extreme funding levels can be dangerous.
Consider this: during collapse phases—such as pre-delisting events—funding rates may become deeply negative as traders pile into shorts. Those trying to "buy the dip" without proper analysis risk entering prematurely and suffering significant losses.
Always respect market structure and trend direction. As in technical trading: trend is your friend.
Why Funding Rate Matters for Exchange Integrity
The importance of funding rates extends beyond individual strategies—it speaks to exchange legitimacy.
Take the infamous JPEX case in 2023. The platform advertised perpetual contracts without funding fees—a red flag. Without this mechanism, futures and spot prices can decouple entirely unless artificially controlled.
Such control implies the exchange—not market forces—is setting prices. That opens doors to manipulation, where quotes favor the house (i.e., the exchange itself acts as counterparty). This model resembles underground futures operations, where operators profit by offering skewed pricing and eventually vanish with user funds.
High guaranteed returns (e.g., 20% deposit yields) were another warning sign—but the absence of funding mechanics was a structural flaw indicating lack of transparency.
A legitimate perpetual market must have a functioning funding rate system.
Frequently Asked Questions (FAQ)
What is funding rate?
Funding rate is a periodic payment exchanged between long and short traders in perpetual contracts to anchor futures prices to spot prices. Positive rates mean longs pay shorts; negative means shorts pay longs.
Why do exchanges use funding rates?
Because perpetual contracts don’t expire, funding rates act as a market-driven correction tool to prevent excessive divergence between futures and spot prices.
How often is funding applied?
Most major exchanges—including Binance—apply funding every 8 hours (three times per day).
Can I avoid paying funding fees?
Yes. Simply close your position before the next funding timestamp. No open position = no payment or receipt.
Is negative funding rate bullish or bearish?
Negative funding indicates bearish sentiment—more traders are shorting—making it costly to hold short positions. However, extremely negative rates may signal oversold conditions or potential reversals.
Should I trade based on funding rate alone?
No. While insightful, funding rate should complement—not replace—technical and fundamental analysis. Used wisely, it enhances timing and risk assessment.
Final Thoughts
Understanding funding rate is essential for anyone trading crypto perpetual futures. It's not just a fee—it's a window into market psychology, balance, and potential inefficiencies.
Whether you're collecting yield through arbitrage or gauging sentiment via shifting rates, mastering this mechanism gives you an edge in volatile markets.
