Arbitrage funding squeeze leading to temporary peg dislocations
Arbitrageurs bridge price differences by employing leverage, cross-venue settlement, and funding strategies; a sudden rise in the cost of any of these inputs reduces the profitability and capacity of such trades.
When funding rates spike, collateral values compress, or settlement corridors become congested, participants may reduce or stop arbitrage activity, allowing price divergence between venues and potentially causing temporary deviations from the reference value that would otherwise be arbitraged away.
Example from market:
During episodes of broader market funding stress, arbitrage desks faced increased costs and operational constraints, which led to widened spreads across venues and short-lived deviations from reference values until either funding normalized or liquidity providers stepped in with priced compensation.
Practical application:
Traders and risk teams treat rising arbitrage costs as a trigger to tighten exposure limits, prefer execution strategies that reduce reliance on cross-venue settlement, and increase hedges against short-term dislocations; market makers may demand wider compensation or reduce quoted sizes.
Metrics:
- funding rate - basis - settlement congestion - liquidity balance Interpretation:
Если фандинг резко растёт и каналы расчётов перегружены → ожидать временного рассогласования и повышать хеджирование; если фандинг и расчёты нормализуются → снижать премии риска и рассматривать восстановление обычных арбитражных операций.
