BitMEX reported that a previously profitable crypto arbitrage approach—buying spot assets while selling perpetual futures to earn funding payments—has effectively disappeared due to widespread adoption. The exchange's analysis attributes the collapse to automation and massive capital flows into similar strategies, which compressed funding yields across venues. As a result, annualized returns from this method fell below 4% by mid‑2024, a marked decline from its historical highs. Projects that built tokenomics around the same mechanics, notably Ethena (ENA), drew billions of capital and accelerated the saturation.
Overview of the Collapsed Arbitrage Strategy
The strategy that BitMEX analysed relied on the funding rate mechanism of perpetual futures: traders bought the underlying cryptocurrency on spot markets and sold equivalent perpetual contracts to capture periodic funding payments. Because the positions offset market direction, the trade was often presented as a yield strategy rather than a directional bet. For years this approach provided steady returns and attracted both retail bots and institutional automation, turning a niche tactic into a widespread market activity.
Mechanics of Funding Rate Arbitrage
Perpetual futures use funding rates to align futures prices with spot prices, creating a recurring payment between longs and shorts. When futures trade at a premium, longs pay shorts; when at a discount, shorts pay longs—this flow is what arbitrageurs targeted. The trade required precise execution and risk controls to keep the synthetic exposure neutral while collecting funding.
- Buy the asset on the spot market to hold the underlying exposure.
- Sell an equivalent perpetual futures position to offset price moves.
- Collect funding payments between the two positions as yield.
Market Saturation and Yield Decline
BitMEX identifies automation and copycat strategies as the main drivers of saturation: as more capital deployed the same mechanics, the supply of automated short positions in perpetuals outpaced demand from natural longs. Protocols like Ethena (ENA) explicitly adopted similar economic designs and attracted large investments, amplifying the imbalance. In consequence, funding rates compressed sharply and annualized yields from this spot‑futures basis trade dropped below 4% by mid‑2024, a dramatic fall from earlier peak periods.
Broader Market Implications
The disappearance of this reliable funding yield changes market structure: one traditional source of crypto portfolio income has diminished, and liquidity dynamics between spot and futures may shift as profitability wanes. Reduced returns from automated arbitrage could lower the steady liquidity provision these systems offered, with knock‑on effects for orderbook depth and execution costs.

Expert Insights and Future Outlook
Researchers tracking crypto derivatives note that rapid information diffusion and low implementation barriers accelerated the strategy's spread and decay. Dr. Elena Rodriguez has commented that this rapid arbitrage decay reflects market maturation: transparent, replicable mechanics allowed fast adoption and quick elimination of the edge. BitMEX's report also outlines possible follow‑on developments, such as a shift toward cross‑exchange or cross‑asset trades, the emergence of new derivative products, and institutional reallocation to other yield sources.
Why this matters (for a miner in Russia with 1–1000 devices)
If you run mining rigs, this development changes one part of the broader crypto income landscape rather than mining economics directly. Funding‑rate arbitrage was a source of portfolio yield for some traders and liquidity providers; its decline does not alter block rewards or equipment performance. However, lowered yields in derivatives can influence traders' behaviour, which in turn may affect spot liquidity and short‑term price moves that miners see when converting mined coins.
What to do?
For small and medium miners the practical steps are straightforward: monitor liquidity and execution conditions on the venues you use, avoid relying on funding income as a predictable revenue stream, and keep cash buffers for periods of higher execution cost or volatility. Consider diversifying how you realise mining proceeds—for example, staggered sell orders or using reputable custody and execution options—to reduce dependence on any single market microstructure advantage. Finally, stay informed about derivatives market changes so you can adapt when traders shift strategies.
