The Secured Overnight Financing Rate (SOFR) is a benchmark interest rate that measures the cost of borrowing cash overnight against U.S. Treasury securities. It is calculated on the basis of actual transaction data from the repurchase agreement market, rather than the survey-based estimates that underpinned its predecessor, LIBOR — which was discontinued following a widely documented manipulation scandal. As a transaction-based reference rate, SOFR provides a more reliable indicator of funding conditions in the wholesale money market. Spikes in SOFR may signal tightening liquidity conditions and increased stress in the financial system, which can translate into headwinds for risk assets. Monitoring interbank and funding rates can therefore offer valuable insight into systemic liquidity and risk appetite. This topic is examined in Module 6.1. Further background available here.

TL;DR: SOFR — The Transaction-Based Replacement for LIBOR
TL;DR: SOFR is a benchmark interest rate that measures the cost of borrowing cash overnight against U.S. Treasury securities, calculated from actual transaction data in the repurchase agreement market. Its transaction-based methodology addresses the structural weaknesses of LIBOR, which was subject to manipulation due to its reliance on survey-based estimates. From a systems perspective, SOFR serves as a diagnostic signal for funding conditions in the wholesale money market — sustained spikes may indicate tightening liquidity and increased financial system stress, often preceding headwinds for risk assets. Monitoring SOFR alongside other funding rates provides market participants with insight into systemic liquidity conditions and the transmission of monetary policy through the financial system, offering an early warning signal for stress events.
