According to BitMEX, differences in funding rates are not random, and understanding why they occur can give traders an advantage.
In its newly released Q2 2026 Derivatives Report, the exchange argues that disparities in funding rates are often driven by market structure rather than market sentiment. Factors such as collateral design, exchange demographics, and index construction can result in permanent differences in funding and recurring trading opportunities.
Looking beyond market sentiment
Perpetual futures do not expire like traditional futures contracts. Instead, exchanges utilize fund settlements between long and short traders to keep perpetual prices in line with the underlying market.
Funding rates are generally considered an indicator of bullish or bearish sentiment. But BitMEX says that interpretation is only part of the story. “While funding rates are often viewed as a simple indicator of market sentiment, the reality is much more nuanced,” he said. peter wilkinsonCEO of BitMEX.
“Our research shows that structural factors such as collateral type, exchange participant profile, and index construction can create persistent funding rate differences that traders can identify and strategically exploit.”
According to the report, traders should first identify: What is causing the funding shortage? before attempting to trade.
Three factors behind the difference in funding rates
This report identifies three structural factors that consistently impact funding rates across the crypto derivatives market.
The first one is Additional design.
BitMEX’s XBTUSD and XBTUSDT Perpetual both track Bitcoin, but they use different collateral. One is margined with Bitcoin and the other uses USDT.
Its characteristics attract different types of traders and create long-term capital spreads.
On average, the difference in funding between the two contracts is approximately 3.93% per annum It has been negative for the past three and a half years. 94% 90 day rolling period.
The second factor is exchange demographics.
When comparing major trading venues, BitMEX found: Hyperliquid’s Bitcoin perpetuals generated an average annual funding premium of 7.17% over Binance Between 2023 and 2026. Ether Perpetual Securities is also Annualized premium 5.31% over the same period.
According to BitMEX, many of the differences reflect differences in the user base.
Hyperliquid’s retail-focused on-chain trading environment tends to maintain higher funding rates, while Binance’s larger institutional presence helps compress spreads through arbitrage.
The report argues that operational hurdles such as custody requirements, compliance restrictions, and cross-chain capital movements continue to limit institutional investor participation in decentralized exchanges, allowing funding premiums to persist.
The third factor is Index construction.
Why oil financing reached -531%
One of the report’s most impressive findings comes from the tokenized goods market.
Unlike Bitcoin perpetual contracts, oil contracts cannot reference a continuously traded spot market. Instead, it derives its price from the previous month’s futures contract.
As these futures prices move from one contract to the next during the backwardation period, the price index will mechanically decline, even if the underlying price of oil remains unchanged.
According to BitMEX, this process will temporarily reduce the funding amount of the WTIUSDT perpetual contract to approximately Annual rate -531% April 2026 futures on roll.
The exchange said the episode shows that funding rates can be driven entirely by exchange mechanics, rather than trader positioning or broader market sentiment.
understand the opportunity
BitMEX believes that traders should understand the structural forces that make the difference between funding rates and not simply treat them as market indicators.
This report explores how funding opportunities emerge across a variety of margin models, trading venues, and perpetual products, while encouraging traders to distinguish between long-term structural inefficiencies and short-lived market events.
The conclusion is simple and clear. Funding rates alone don’t tell the whole story.
Understanding why funding rates differ can prove to be just as valuable as the funding rates themselves. The full report “3 Sources of Funding Rate Alpha” is available on the BitMEX Blog.
