Small firms do not borrow at the ten-year Treasury yield. On Friday that yield was 4.94 percent. A lender's quote, if a firm receives one this week, will be a different number, built from a benchmark the contract names and a spread the bank sets.
What the public yield changes is the conversation, not the payroll calendar. Wages that were promised are still due on the date they were promised. A higher reference rate makes carrying a balance more expensive when the agreement says the rate floats. A fixed-rate loan signed earlier does not reread the Fed statement.
