Bitcoin's price has surged to $81,000, but the derivatives market has signaled an unusual trend: the longest period of negative funding rates since the beginning of the century.
According to reports, leading cryptocurrencies rose 2.9% in the past 24 hours and are currently trading around $81,250.CoinGecko
The 30-day average funding rate for Bitcoin has been negative for 66 consecutive days, according to data released on Monday for perpetual contracts—a type of contract that tracks the spot price of Bitcoin with no expiration date. Tweet from Vetle Lund, Research Director at K33 Research.
When the funding rate becomes negative, short positions pay a daily fee to long positions to keep the contract price aligned with the spot price—the longer the position is held, the higher the cost.
“The reason I’m paying attention to this policy is simple: timing,” Lund said. “Sustained negative financing rates have historically been a strong indicator of when you should make a decisive buy.”
This series of declines follows a 12% rally in April, raising a key question: Is sustained negative funding a true sign of panic, or a structurally different issue?
Institutional hedging, not fear
Derek Lim, Head of Research at cryptocurrency market maker Caladan, said that while open interest increased by approximately 12% over the past month, funding rates remained persistently negative, indicating that the root cause of the supply shortage lies in structural factors rather than short squeezes.
Lin stated: "When the market is more institutionalized, capital flows are an indicator of capital movement, not market sentiment." Decrypt "Persistent negative data reflects short positions in perpetual contracts provided by delta-neutral trading desks, not directional bearish sentiment."
He noted that three major institutional fund flows dominate: hedge funds shorting futures during investor redemption periods; basis traders going long on equities while shorting Bitcoin perpetual contracts to capture equity premiums; and miners shifting to AI computing while hedging their Bitcoin holdings. Each of these flows is mechanical and price-insensitive.
Andri Fauzan Adziima, Head of Research at Bitrue Research Institute, said that in April, U.S. spot Bitcoin ETFs recorded net inflows of approximately $2.44 billion, the strongest month since 2026. Institutional investors bought spot Bitcoin while shorting futures to manage risk. Decrypt“This is not primarily driven by panic-driven retail shorting, but rather reflects a maturing market.”
Currently, short sellers need to pay an annualized rate of approximately 12% to maintain their short positions, yet the market has not declined.
Since 2018, historical analysis of six similar negative funding strategies has shown that all six achieved positive returns within 90 days, with win rates ranging from 83% to 96%—compared to a win rate of only 55% to 75% for random entries, according to Lund's data. The average maximum drawdown during these strategies also decreased from 16% to just 5%.
What will destroy this regime?
Three analysts agree that a sustained breakout above key resistance levels is most likely to trigger a squeeze.
Matthew Pinnock, Chief Operating Officer of Altura DeFi, said: "If short sellers are forced to cover and funding rates turn positive, Bitcoin could rapidly break above $100,000 in a squeeze." Decrypt "If spot demand cools before then, the price may reset and consolidate around $70,000 to $75,000."
Investors in prediction markets countless from all decrypted parent company Dastan remain optimistic and assign a 84% probability that the leading cryptocurrency will continue to rise, with the next target testing $84,000.
Mr. Lin has a more precise judgment of key price levels. “If the price breaks below $82,000 and the ETF fund flows are confirmed, it means the price has breached this level,” he said. “The question is whether this squeeze represents a shift in market structure or merely a tactical move within institutional hedging mechanisms.”
The Singapore-based trading firm QCP Capitalnotably holds a similar view that $82,000 is a key resistance level for Bitcoin’s recovery, potentially determining its success or failure. The $80,000 to $82,000 range also coincides with the 200-day exponential moving average, making this area difficult to break through.
This 66-day streak of continuous gains remains strong. “Short sellers have finally felt the pain,” said Glassnode analyst cryptovizart. said in a recent analysis of April positioning data, “but on the other side, there are people who aren’t selling.”
