What it means
LIBOR was a survey-based estimate of interbank borrowing costs and served as the index for an enormous volume of floating-rate debt. Following manipulation findings and the decline of the underlying market it was wound down, with the remaining US dollar settings ceasing in mid-2023.
SOFR — the Secured Overnight Financing Rate — is the principal US replacement. It is a transaction-based rate on overnight Treasury repo, which makes it robust but also different in character: it is secured and near risk-free where LIBOR embedded bank credit risk, and it is backward-looking where LIBOR was a forward term rate. Term SOFR was developed to address the second point.
What happened to legacy contracts
Well-drafted agreements contained benchmark replacement provisions selecting a successor index and applying a spread adjustment to keep economics broadly neutral. Poorly drafted ones — many of them, particularly in smaller commercial loans — had fallbacks written for temporary unavailability, such as reverting to the last published rate or to a lender-selected alternative, neither of which works when the index disappears permanently. Federal legislation supplied a statutory replacement for many contracts governed by US law that lacked workable fallbacks.
What this means for a small-business borrower now
New commercial floating-rate paper is priced off SOFR, off prime, or off a lender's own cost-of-funds index. Prime-based lending, which is the majority of small-business bank lending and all SBA 7(a) variable-rate lending, was unaffected throughout.
Where this one catches people
The index is only half the price. When a legacy loan was converted from LIBOR to SOFR, a spread adjustment should have accompanied the change to account for the different character of the two rates. Borrowers who checked only that the index changed, without checking whether the margin and the adjustment together preserved the original economics, may be paying more than the transition was intended to produce. The comparison to make is index plus margin plus adjustment, before and after.
