Let's be clear up front: this is not a call on what the Reserve Bank will do next. It's a reminder that path uncertainty is a finance operating problem — and scenario packs are how you handle it without improvising the morning after.

Where we sit (facts, not a view)

The RBA cash rate is 4.35% after the 12 August 2026 hold. Into mid-September, market commentary has been pricing hike risk into the late-September window. You don't need a precise probability to act. You need the desk ready for more than one outcome.

CFOs feel it in interest cost and covenant headroom. Finance managers feel it when the board pack still shows a single "base." Treasury and recon feel it when debt service and facility assumptions weren't refreshed before someone asks "what if?"

Why "update after the meeting" fails

A single-path pack trains the organisation to wait. Waiting compresses judgement into a short window — usually the same week you're closing, explaining variance, and fielding lender or board questions. Treasury ends up rewriting interest lines under lights; FP&A debates which "base" was live; the CFO gets a verbal update instead of a pack someone already stress-tested.

Better: two packs that share the same actuals spine and diverge only on the rate path and the handful of assumptions that actually move with it. That's scenario craft, not prediction theatre — and it keeps recon and debt-service owners in the loop before the headline hits.

Hold vs +25bp — what to own

Build both packs off the same reconciled cash and debt position.

In both packs, lock:

  • Opening cash and undrawn facilities by entity
  • Contracted debt service and known maturities
  • Payroll, tax, and material AR/AP timing you already trust

In the +25bp pack, refresh explicitly:

  • Floating-rate interest cost for the forecast horizon
  • Covenant headroom where rates or interest cover bite
  • Any customer or supplier behaviour you'd genuinely change (don't invent drama — only model what you'd actually discuss)
  • FX and cross-currency debt service if your book is exposed

Name the owners: who updates the rate assumption, who signs off covenant maths, who tells the board which pack is "live" after the decision.

Desk checklist (use this week)

  1. Confirm cash rate assumption in the current 13-week and board scenarios — is it still 4.35% hold-only?
  2. Produce a +25bp twin with interest and covenant lines highlighted, not buried.
  3. List three decisions that change if +25bp lands (draw, hedge, pay-down, collections push, capex timing).
  4. Agree who flips the pack within one business day of the RBA outcome.
  5. Keep a one-pager of "what we believed on [date]" so audit and the board can reconstruct the path later.

What this is not

It's not macro thought-leadership. It's not a vendor pitch for a planning tool. It's desk craft: multiple paths, owned assumptions, and a clear handoff so you're not rewriting the pack under lights.
