# What is the Funding Rate?
In the world of crypto trading, Perpetual Futures (often called "perps") are the most popular instrument. Unlike traditional futures contracts that expire on a specific date (e.g., monthly or quarterly), perpetual contracts never expire. You can hold a position for minutes or years.
But this creates a problem: How do we ensure the contract price stays close to the actual spot price of Bitcoin or Ethereum?
If everyone buys (longs) the perp contract, its price could go to $70,000 while the spot price is only $60,000. To prevent this huge gap, exchanges use a mechanism called Funding Rate.
> Key Concept: Funding Rate is a periodic payment exchanged between long and short traders to anchor the futures price to the spot price. It is NOT a fee paid to the exchange.
## How It Works: The Mechanism
The funding rate calculation happens typically every 8 hours (00:00, 08:00, 16:00 UTC).
Positive Funding (+): This means the Perp Price is higher* than the Spot Price. The market is bullish.
Result:* Long traders pay Short traders.
Incentive:* This encourages traders to close Longs (sell) or open Shorts (sell), pushing the price down towards spot.
Negative Funding (-): This means the Perp Price is lower* than the Spot Price. The market is bearish.
Result:* Short traders pay Long traders.
Incentive:* This encourages traders to close Shorts (buy) or open Longs (buy), pushing the price up towards spot.
## Using Funding as a Sentiment Indicator
For smart traders, the funding rate is one of the most powerful sentiment indicators available. It tells you how the majority of the market is positioned and how aggressive they are using leverage.
### 1. High Positive Funding (> 0.05%)
This indicates extreme greed. Retail traders are piling into long positions with high leverage.
Risk: High probability of a Long Squeeze*. Whales might sell to push the price down, triggering a cascade of liquidations from these over-leveraged longs.
Strategy:* Be cautious about opening new longs. Look for bearish divergence or breakdown structures.
### 2. Deep Negative Funding (< -0.05%)
This indicates extreme fear. Traders are aggressively shorting the market, expecting it to go to zero.
Risk: High probability of a Short Squeeze*. A small price pump can trigger the stop-losses of these shorts, fueling a massive rally.
Strategy:* This is often a good time to look for long entries (contrarian trade).
## Annualized Costs
Funding rates might look small (0.01%), but they add up.
0.01% per 8 hours:* ~11% APY (Normal baseline)
0.1% per 8 hours:* ~109% APY (Very expensive!)
If you hold a position for weeks while the funding rate is high against you, it can significantly eat into your profits.
## Summary
Funding Rate* keeps the perp price in line with spot.
Longs pay Shorts* when positive (Bullish).
Shorts pay Longs* when negative (Bearish).
Use extreme funding rates as a Contrarian Signal* to spot potential market reversals.
