Market Resiliency
The capacity of prices, spreads and depth to normalize after a disturbance.

How Market Resiliency works
Liquidity is multidimensional. A market can show a narrow spread yet have little executable size, or display depth that disappears under pressure. Microstructure therefore separates tightness, depth, immediacy, impact and resiliency rather than treating liquidity as a single number. Market Resiliency captures one part of the cost or capacity of trading. It should be interpreted together with trade size, volatility and the amount of immediately executable liquidity, because the same quoted market can behave very differently for a small order and an institutional-size transaction.
Why it matters in markets
For bonds, transaction costs often rise sharply when issue size is small, dealer capacity is constrained or volatility increases. Liquidity conditions can also become embedded in yield spreads and relative-value relationships. Understanding Market Resiliency helps distinguish a fundamental repricing from a move caused primarily by execution mechanics, inventory pressure or temporary scarcity of liquidity. That distinction is important when comparing yields, spreads or prices across instruments and venues.
How to interpret it
The concept should be read in context rather than as a standalone signal. Compare Market Resiliency with prevailing volatility, trade size, spreads, depth and the execution protocol in use. A change can reflect information, inventory management, market-design rules or simply the timing of a large order.
Limits and context
Microstructure measures are highly sensitive to market design and data quality. Public feeds may omit hidden interest, bilateral dealer negotiations or delayed reports, while definitions can vary across venues and jurisdictions. BondStats therefore treats Market Resiliency as a structural concept rather than a universal trading rule, and users should defer to the relevant venue, regulator or instrument documentation for binding definitions.
