If you run a legacy operating business: trucking, general contracting, logistics, any service line with long-term contracts and a relatively stable client base. You may eventually hit something referred to as a “Harvest Period”. This is where we see new investment slow, or stop. Cash builds, and it looks good sitting in the company account. For a lot of owners, that’s the whole point, the thing they’ve been working toward, a sign the business has achieved success.
But idle cash has a cost.
The math nobody runs
Take $100,000 earned in 2016 and hold it, uninvested, for ten years. Based on cumulative U.S. inflation since 2016 (roughly 39%, per Bureau of Labor Statistics CPI data), that $100,000 now buys what $71,876 would have bought in 2016, a 28.1% loss in real purchasing power. (CPI inflation calculator, BLS data)
That’s not a market downturn. Nobody had to make a bad trade. The money just sat there while the cost of everything it could buy went up. “Uninvested” is a choice, it means earning next to nothing: 0.01% in a standard checking account, maybe 3-4% in a high-yield savings account if the owner bothered to move it. Either way, at current interest rate levels the opportunity cost compounds further: every quarter that capital sits at that kind of return, the debt market and the operating businesses around you are pricing in a cost of capital you’re refusing to use.
Owners rarely see it this way because the loss is silent. There’s no invoice for it, no line item. The taxman announces himself. Inflation doesn’t.
Why this moment matters
The instinct to build a cash reserve after a strong run isn’t wrong. “Cash is king”, and reserves fund the next move or protect against the next downturn. The mistake is treating the reserve as the destination instead of the staging ground.
The businesses that compound value are the ones that use a strong Harvest Period as the funding source for the next structural move. Now whether that looks like vertical integration, a scarce asset acquisition, or adding a new revenue line, using the capital while fresh is key. The ones that don’t are the ones still holding the “same reserve” that’s quietly smaller, five years later.
This is the whole idea behind Momentum, Managed: the operators who are already winning are the ones with the most leverage to deploy capital well. The risk was never losing what you built. It’s letting it erode while you decide what to do with it.
What “deploying it well” actually requires
Redeploying idle capital isn’t a single decision, it’s a continued exercise. Where the capital goes, what structure it takes, and what constraints govern the return all depend on the specific asset and sector. A legacy transport operator evaluating a move into dock ownership is a different case than an operator weighing a scarce-asset acquisition against reinvesting in the business itself. This is exactly the kind of underwriting and valuation work we take on regularly.
The point of this piece is narrower: don’t let the decision default to inaction. A cash pile that looks conservative on the balance sheet is quietly losing to inflation every quarter it sits still, and “we’ll figure out what to do with it later” is itself a decision, just an unpriced one.
If you’re sitting on capital from a strong run and haven’t scoped where it should go next, that’s the conversation worth having before the next quarter’s inflation print makes the decision for you.
