A dollar interest-rate screen can display SOFR, effective federal funds and a Federal Reserve target range together. They are connected, but each answers a different question. The New York Fed defines SOFR as the cost of overnight cash borrowing secured by Treasury securities. That collateral requirement is central to interpreting the benchmark.

WFN analysis: suppose, purely as an illustration, that one funding benchmark rises while the announced policy range is unchanged. The observation tells us that measured borrowing conditions changed. Establishing the cause would require evidence about the relevant transactions and market conditions. It would be premature to describe the move itself as a new policy decision. A research workflow can compare the benchmarks on the same observation date, retaining their publication times and units. The difference between two percentages is a spread, usually expressed in basis points. If hypothetical rates are 4.10% and 4.15%, the difference is five basis points. These values are arithmetic examples, not current market observations. The distinction also matters when reviewing a broker’s financing charge. A contractual formula may reference a benchmark and add its own spread, adjustment or calendar convention. A screen displaying the underlying benchmark alone cannot reproduce that formula. The starting point is the actual financing term and the specific rate series it names.

For a dollar briefing, keep three questions separate: what policymakers announced, what overnight transactions recorded, and what a particular customer was charged. A document that merges all three into one rate can hide the origin of a change. Storing source labels and dates alongside the figures makes later comparisons easier to reproduce. An exchange-rate interpretation then needs an additional step. A funding spread can inform an argument about financing conditions, but it does not specify a future currency price. Set out the proposed transmission channel and the evidence that would challenge it, including the rate environment on the other side of the currency pair. That keeps the analysis open to verification.
What the two transaction benchmarks measure
SOFR uses a volume-weighted median of eligible repo transactions. Its published methodology combines several Treasury repo segments and filters a portion of transactions associated with special collateral demand. The New York Fed normally publishes the observation at approximately 8:00 a.m. Eastern Time on business days. New York Fed: SOFR definition and methodology
The effective federal funds rate measures overnight unsecured borrowing by depository institutions from eligible counterparties. It is also a volume-weighted median. The Fed’s policy committee establishes a target or target range for the federal funds market; the observed transaction rate and the policy decision remain separately identifiable records.
