Liquidity Stress Index SOFR - IORBLiquidity Stress Index (SOFR - IORB) 
This indicator tracks the spread between the  Secured Overnight Financing Rate (SOFR)  and the  Interest on Reserve Balances (IORB)  set by the Federal Reserve.
A persistently positive spread may indicate funding stress or liquidity shortages in the repo market, as it suggests overnight lending rates exceed the risk-free rate banks earn at the Fed.
Useful for monitoring monetary policy transmission or market/liquidity stress.
