Liquidity fragmentation between private and public settlement layers
Сoncentration of trading and transfers into privacy-preserving settlement rails reduces the share of accessible, transparent liquidity available to public venues and market makers.
This phenomenon arises because a portion of supply and demand is routed through settlement mechanisms that mask counterparties and balances, making those flows invisible to conventional liquidity providers and algorithmic market-making strategies; the effective displayed liquidity therefore underestimates true market depth and execution risks increase.
Example from market:
In periods when participants favored opaque settlement mechanisms due to counterparty or regulatory concerns, public order book depth declined and visible spread metrics deteriorated even as aggregate activity across all rails remained stable.
In other episodes, sudden outflows into non-transparent rails coincided with spikes in transaction cost metrics on public venues as liquidity providers widened quotes or withdrew.
Practical application:
Risk managers and traders monitor the balance between transparent and non-transparent settlement volumes to adjust execution tactics; common responses include widening execution horizons, preferring limit strategies, staging large trades, or using dedicated hidden-liquidity execution services to mitigate slippage.
Metrics:
- net exchange flows - order book depth - spreads - liquidity balance Interpretation:
Если доля приватных расчётов растёт → видимая ликвидность может стать ненадёжной и следует ужесточить контроль рисков; если приватные потоки снижаются → видимая глубина может восстановиться, что облегчает крупные исполнения.
