Understanding Funding Rates in Crypto

What Are Funding Rates?

In the world of crypto perpetual futures, funding rates are small, periodic payments exchanged between traders — typically every few hours — to keep perpetual contract prices aligned with the spot market.

Here’s how it works:

• If the perpetual trades above the spot price, longs pay shorts.
• If it trades below spot, shorts pay longs.

This mechanism helps reduce price imbalances by financially encouraging traders to take the less crowded side of the market.

What many traders overlook is that not all funding rates are created equal — each exchange has its own rules.

• Some calculate it every 8 hours, others hourly or even more frequently.
• The formula, timing, and historical volatility of the rates vary by platform.
• Some platforms even allow custom funding models, especially in decentralized environments.

Why Do They Matter?

Funding rates aren’t just a technical detail — they can make or break your trade.

When they work against you, they can slowly eat away your gains or even turn a good trade into a losing one. But when used strategically, they can also become a steady source of income or a powerful edge in arbitrage setups.

Depending on the rate and your approach, you can:

• Earn passive yield just by holding positions with positive funding.
• Capitalize on imbalances by opening opposing positions across spot and perpetuals.
• Take advantage of short-term sentiment shifts, often revealed in sudden funding spikes

This is where smart arbitrage begins: spotting these inefficiencies before others do.

Can You Arbitrage Funding?

Yes — and that’s one of the core ideas behind Smartbitrage. Imagine you go long on spot and short on futures. If the funding rate is in your favor (e.g., shorts receive funding), you earn that funding without being exposed to price risk. That’s a classic delta-neutral strategy.

There’s more nuance, of course — including fees, leverage, and market behavior — but the basic idea is that funding rates allow you to capture yield with low risk when done right.
