Your 2027 Plan Assumed Interest Rate Cuts. You Got a Hike

Most 2027 operating plans were drafted between June and August. Every one of them carried a cost of capital assumption, and that assumption is now wrong in the opposite direction.

‍

The real problem

On September 16 the Fed raised rates by 25 basis points to a target range of 3.75 to 4.00 percent, the first hike since July 2023. That ended nearly two years of easing. Markets are now pricing additional increases at the last two meetings of the year, which would put the funds rate at 4 to 4.25 percent, and futures point toward roughly 4.8 percent by late 2027.

The expectation is still moving. A month ago, futures put October 2027 near 4.3 percent. It is now closer to 4.8. So even the companies that reforecast in late September are already behind the market.

None of that is a forecast you need to agree with. The point is narrower. Your plan assumed one direction and the environment moved the other way, after the plan was written.

Why nobody reopens the plan

Planning cycles are designed to close. By October the budget has been socialized, headcount has been allocated by function, and every leader in the building has already fought for their number. Reopening it means reopening all of it.

So the macro assumption gets updated in the finance model and nowhere else. The hiring plan it produced stays exactly as it was. That gap is the whole problem, and it is invisible until March, when the first few hires come in and the returns do not look like the model said they would.

‍

Four assumptions that quietly broke

1. The cost of anything debt-funded. If the plan includes an acquisition, a facility, a systems investment, or any growth financed rather than funded from cash, the price of that money went up and is expected to keep going up. Headcount attached to those projects inherits the change. A team hired to integrate an acquisition is a different decision if the acquisition gets repriced or delayed.

2. The payback period on a growth hire. Every hire has an implied hurdle. When capital costs more, the bar for what a new senior person has to return rises with it. A VP of Sales who pays back in eighteen months at one cost of capital may not clear the bar at another. Most plans never wrote the hurdle down, which is exactly why it does not get revisited when it moves.

3. Headcount tied to deal activity. Plenty of 2027 plans assume transactions: a raise, a sale, a tuck-in, a refinancing. Those timelines move when rates move. The hires sequenced against them, in corporate development, integration, and the finance team that supports a process, are now pegged to dates that may not hold.

4. The retention budget. This is the one that bites first. Flexibility pools were set thin on the assumption of a calm year. A tighter capital environment makes companies more protective of the leaders they already have, which makes competitors more aggressive about paying for them. The market for your best people does not slow down because your plan did.

What to actually do about it

Not reopen the plan. That is not realistic in October and it is not necessary.

Pull the five to ten hires in the plan that carry the most cost and the most dependency on something external. For each one, write down the assumption that justified it. If the assumption is a deal closing, a financing clearing, or a payback period that was never stated, flag it.

That is a two-hour exercise and it produces a short list of hires that need a second look before anyone starts a search. It also gives you something useful to hand the board, which is a plan that names its own dependencies instead of pretending it has none.

The close

The companies that get hurt here will not be the ones that guessed the Fed wrong. Nobody is grading you on that.

They will be the ones that built a hiring plan on an assumption, watched the assumption reverse in public, and never went back to check which hires it was holding up.

Worth a read if you are finalizing 2027 headcount, or trying to work out which hires in the plan are still underwritten by something that changed.
