The Bank Prime Loan Rate rose to 6.87% and the Fed Discount Window rate sits at 4% — here's what that combination actually means for your business credit file and your next tradeline.
A note on terminology used on this page: BCC Supplies does not lend money. A BCC Supplies membership is a commercial installment contract, reported to the business credit bureaus as a business installment tradeline — some pages also describe this as an "installment loan" in a descriptive sense, not a cash loan from a lender.

The Bank Prime Loan Rate climbed to 6.87% as of September 1, 2026, up from 6.75% the month before.1 This is the benchmark most banks use to price variable-rate business lines of credit, credit cards, and some installment products, so a move like this one shows up in your statements before it shows up in the news.
Prime rate increases don't change what's already on your business credit file, but they change the terms on new or renewing tradelines going forward.1 A lender quoting "Prime plus 3" today is quoting a higher number than it would have in August, which matters when you're comparing offers for a new business installment tradeline.
The prime rate moved from 6.75% on August 1, 2026 to 6.87% on September 1, 2026 — a 0.12 percentage point increase in one month.1 That's a small jump compared to a full rate-hike cycle, but it's still a real cost increase on any variable-rate balance tied to prime.
For a business carrying a $50,000 variable-rate line at Prime plus 2%, that single monthly move adds roughly $60 a year in interest on its own, before compounding with any future increases.1 It's a reminder that fixed-rate business installment tradelines carry predictable payments regardless of what prime does next month.
The Discount Window Primary Credit Rate stands at 4% as of October 1, 2026.2 This is the rate the Federal Reserve charges banks that borrow directly from it, not a rate your business ever sees on an invoice — but it signals how the Fed is pricing short-term liquidity for the banking system that ultimately extends your credit lines.
Prime at 6.87% and the discount rate at 4% move for related reasons, since both track the Fed's broader policy stance, even though they serve different purposes in the banking system.12 When banks' own borrowing costs rise, that pressure tends to flow through to the rates they offer business borrowers, including on lines tied to prime.
Your business credit file doesn't record the prime rate or the discount rate directly — it records your payment history, utilization, and account mix. But the rate environment shapes what new tradelines cost you, which shapes how much utilization shows up on your report and how affordable it is to pay down.
No — a prime rate change doesn't rewrite history already reported to Dun & Bradstreet, Experian Business, or Equifax Business.1 What it does affect is your ability to keep making on-time payments if you're carrying variable-rate debt, because a higher rate means a higher minimum payment on revolving balances.
Missed or late payments caused by rate-driven payment increases do get reported, and those are what actually move your PAYDEX, Intelliscore Plus, or Equifax Business Credit Risk Score.1 If a variable-rate obligation is getting harder to carry at 6.87% prime, that's worth addressing before a payment slips, not after it's already furnished to the bureaus.
This is also where fixed-payment installment tradelines behave differently from revolving lines: the payment amount doesn't move when prime moves, which keeps the reported payment history consistent regardless of what the Fed does next.1
With prime at 6.87% and the discount window rate at 4%, both trending upward over the past two months, the practical move is to audit which of your current tradelines carry variable rates and which are fixed.12 Variable-rate balances will cost more to carry through the rest of 2026 if this trend continues.
It's also a good moment to check your utilization ratio on revolving accounts, since rising rates often push business owners to carry balances longer, and high utilization is one of the more visible drags on a business credit score.1 Pairing a revolving account with a fixed-payment installment tradeline can diversify your reported account mix so a single rate move doesn't swing your whole file.
