How Volatility Interruption works
Flow and stress indicators describe how trading pressure changes the quality of a market. Imbalances, cancellations, abrupt changes in trade intensity and the disappearance of depth can provide a more immediate view than end-of-day prices alone. Volatility Interruption is best understood as part of the chain connecting trading interest to an observable transaction price. Its effect depends on the market's participant mix, transparency, liquidity and the rules governing interaction.
Why it matters in markets
In fixed income, these effects can be amplified by dealer risk limits and funding constraints, turning a local execution problem into a broader repricing or liquidity event. Understanding Volatility Interruption 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 Volatility Interruption 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 Volatility Interruption 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.
