Cross‑venue arb compression signaling improved market integration
Compression of cross‑venue arbitrage manifests as reduced price dispersion, lower trading costs and tighter spreads across venues and instruments.
It typically arises from better liquidity routing, increased participation of market‑making entities, or more balanced buy/sell flows that eliminate persistent imbalances exploitable by arbitrageurs.
The mechanism reduces frictions:
Tighter spreads and easier execution encourage participation and reduce the compensation required for bearing execution and counterparty risk.
While beneficial for market efficiency, it diminishes simple arbitrage profits and can change the risk/reward profile of certain strategies, shifting alpha generation toward more sophisticated approaches.
Example from market:
В периоды улучшения структуры торговых сетей и увеличения маркет‑мейкинга наблюдалось сужение межплощадочных спредов и базисов, что снижало транзакционные издержки и ускоряло ценовую конвергенцию между ликвидными и менее ликвидными площадками.
Practical application:
Trading desks adjust by focusing on execution quality and latency; arbitrageurs require more capital efficiency and faster execution to capture remaining opportunities; portfolio managers can reduce transaction cost assumptions and tighten expected slippage parameters.
Metrics:
- spreads - basis - order book depth - latency exposure Interpretation:
If spreads and basis compress across venues → improved liquidity integration, lower execution cost but fewer simple arb opportunities; if dispersion widens or depth decreases → rising frictions, re‑emergence of arb windows and higher transaction costs.
