How to Read Crypto Funding Rates
A plain-English guide to perpetual funding rates: what positive and negative funding mean, how to spot crowded longs and shorts, and how to use funding extremes.
What a funding rate is
On a perpetual future there is no expiry, so exchanges use a small recurring payment — the funding rate — to keep the perp price tethered to spot. It is usually exchanged every 8 hours between longs and shorts.
Positive vs negative funding
Positive funding means the perp trades above spot, so longs pay shorts — the market is leaning long. Negative funding means the perp trades below spot, so shorts pay longs — the market is leaning short.
Reading extremes
When funding is very positive, longs are crowded and paying a premium to hold; a stall in price can trigger a long squeeze. When funding is deeply negative, shorts are crowded and a bounce can force a short squeeze. Funding is strongest as a signal alongside open interest and long/short positioning.
Watch the cost
At high leverage the funding cost compounds fast and can quietly drain a position even when price is flat. Always factor it into your hold time.
FAQ
What does a high funding rate mean?
High positive funding means the market is heavily long and longs are paying to hold — a sign of crowded longs that can fuel a short squeeze on a pullback.
Is negative funding bullish?
Negative funding means shorts are crowded and paying longs. It is often read contrarily as a setup for a squeeze higher, but it is one signal among funding, open interest and price.
