If you run a consultancy, agency, or professional practice, interest rate announcements probably fall into the category of “important, but not urgent”, until the day your overdraft renewal lands on your desk, or a client asks what the rate move means for their retainer, and you realise you filed the news away without actually working out what it costs you.
On 23 September, the South African Reserve Bank’s Monetary Policy Committee [RATE OUTCOME] the repo rate, bringing it to [NEW REPO RATE]%. That single number ripples through prime lending rates, overdraft costs, invoice financing terms, and, for many of our clients, the gap between doing the work and getting paid for it.
Here’s what it actually means for your business this quarter, and what to do about it.
Why This Matters More for Services Businesses Than It Looks
Agencies, consultancies, and professional firms carry a specific kind of cash flow risk that product businesses don’t: you often pay salaries, software subscriptions, and contractor invoices in real time, while your own invoices sit on 30-, 60-, or sometimes 90-day terms. That gap is your working capital exposure, and it’s usually plugged with some combination of an overdraft facility, a business credit line, or invoice/debtor financing.
All three of those are priced off prime, which moves in lockstep with the repo rate. So when the repo rate shifts, you’re not just reading financial news, you’re looking at a direct change to what it costs you to bridge the gap between “invoice sent” and “invoice paid.”
The businesses that get caught off guard aren’t the ones without financing. They’re the ones who never worked out what their financing actually costs per rand of working capital, so they can’t tell whether a rate move is a rounding error or a reason to act.
Translating the Number Into Rand Terms
Prime lending rate typically sits at repo plus 3.5 percentage points, so a move in the repo rate flows through to your overdraft, credit facility, or asset finance rate roughly one-for-one, usually within a billing cycle or two.
Do this exercise with your bookkeeper or virtual CFO this week, not “eventually”:
- Add up your interest-bearing short-term debt, overdraft balance, credit card float carried month to month, any invoice discounting facility, short-term asset finance.
- Multiply that balance by the rate change to get your actual annual rand impact. On a R500,000 average overdraft balance, even a 0.25 percentage point move is roughly R1,250 a year, not dramatic on its own, but it compounds with every other cost pressure you’re already carrying (software price increases in USD, salary adjustments, rent escalations).
- Check whether your facility reprices immediately or on a lag. Some bank overdrafts adjust automatically the month after a repo change; others have a notice period. Know which one you have before you need to know.
This isn’t about panicking over small numbers. It’s about not being the business owner who finds out their financing costs changed three months after the fact, buried in a bank statement they didn’t read closely.
Debt Repricing Decisions to Make This Quarter
Whatever direction the rate moved, there are a handful of decisions worth actually making this quarter rather than leaving on autopilot:
If rates moved down: Don’t just enjoy the lower repayment and move on. This is the moment to ask whether you should be accelerating debt repayment while servicing costs are lower, or redirecting the saving into something that compounds, clearing higher-cost credit card debt, building a cash buffer, or funding a hire you’ve been putting off. A rate cut that just quietly lowers your overdraft interest without you redirecting the saving anywhere is a missed opportunity, not a win.
If rates moved up: Look at refinancing options before your existing facility renews. If you’ve been sitting on a variable-rate overdraft for years without shopping it, a rate hike is a natural trigger to get quotes on invoice financing or a term loan instead, sometimes a fixed-rate facility that looked unnecessary at the old rate makes sense at the new one.
If rates held steady: Don’t treat “no change” as “no action needed.” A hold after a hiking or cutting cycle is often the calm before the next move. Use the stability to renegotiate terms with your bank from a position of predictability, rather than waiting for the next announcement to force your hand.
Should You Lock In Financing Now, or Wait?
This is the question we get asked most after every MPC announcement, and the honest answer is: it depends on your specific exposure, not on trying to time the market.
A few practical filters to run it through:
- If you’re already financing working capital gaps and your facility is variable-rate, the cost of waiting to “see what happens next” is usually small compared to the cost of carrying an expensive facility for another quarter. Get quotes now; you can always decline them.
- If you’re considering financing for the first time, say, because you’re taking on a big retainer client with 60-day terms, don’t let the rate decision itself be the deciding factor. The bigger question is whether your margins can absorb financing costs at all, which is a cash flow modelling exercise, not a headline-reading one.
- If you’re planning a major purchase (office fit-out, equipment, a company vehicle) financed over several years, locking in a fixed rate removes the guesswork of the next two or three MPC cycles. That certainty has value even if it costs slightly more today.
The one move we’d caution against: making a financing decision purely reactively, the week of an announcement, without modelling it against your actual cash flow forecast. Rate decisions are inputs to that model, not replacements for it.
Talking Points When Clients Ask “What Does This Mean for Us?”
If you bill clients who are watching the same headlines, having a clear, confident answer ready is part of being seen as the professional partner they rely on, not just the person who sends the invoice. A few lines that hold up regardless of which way the rate moved:
- “We’re watching the impact on our own financing costs and client payment terms, and we’ll flag anything that affects your project budget directly, we’re not going to pass through noise.”
- “This affects our cost of working capital, not the value of the work, our fees are based on scope, not on interest rate movements.”
- “If this changes anything meaningful for your project or retainer, we’ll come to you with specifics, not vague warnings.”
That combination of transparency and calm is what separates a firm clients trust with more work from one they start shopping around on price.
The Real Lesson Here Isn’t About This One Announcement
Rate decisions come around every two months. If each one sends you scrambling to figure out your exposure from scratch, that’s a sign your business is missing the cash flow visibility that makes these announcements a non-event instead of a fire drill.
That’s exactly the gap a virtual CFO closes, not by predicting what the SARB will do next, but by making sure you always know your financing costs, your working capital position, and your options, so a rate announcement is just an input you plug into a model you already have, not a reason to panic.
