What a 5.3% Treasury Yield Does to Your Company's Valuation

The 10-year U.S. Treasury yield rose above 5.35% this week, its highest level since 2002, according to Forbes and Reuters reporting on LSEG data. For owners of private companies the move matters well beyond the bond market, because the Treasury yield is the starting point for the discount rate, the return a buyer or appraiser requires before agreeing to a price. When that starting point rises, the value placed on the same cash flows falls unless something else offsets it.

Why a government bond yield sets your company's price

A business is worth the cash it is expected to produce, translated into today's dollars. The translation uses a discount rate, which reflects what an investor could earn elsewhere plus extra compensation for the risk of owning this particular business. The "elsewhere" part is anchored to the 10-year Treasury yield, the closest thing to a risk-free return. Appraisers typically build the rate from the bottom: the risk-free rate, plus an equity risk premium (the extra return investors expect from stocks over government bonds), plus premiums for small size and for risks specific to the company, such as customer concentration or dependence on the founder.

That structure means a higher Treasury yield flows through to every private valuation, whether it is prepared for a sale, a gift or estate plan, a buy-sell agreement, a stock option grant under Section 409A, or a fairness opinion. Reuters reported on October 1 that the 10-year yield reached 5.34% after its largest quarterly rise this century, and that Morgan Stanley's global M&A head, John Collins, said higher yields make valuations "sometimes a little tougher." Forbes reported on October 7 that the 30-year yield reached 5.70% and that the Federal Reserve raised its benchmark rate on September 16 to a range of 3.75% to 4.0%.

How the discount rate moves value

A simple example shows the size of the effect. These numbers are hypothetical and chosen for illustration. Suppose a company's cash flows are expected to grow 3% a year indefinitely, and an appraiser's discount rate is 14%. Under the capitalization approach, which divides next year's cash flow by the discount rate minus the growth rate, the business is worth about 9.1 times next year's cash flow (1 divided by 0.11). If the discount rate rises to 16%, the multiple falls to about 7.7 (1 divided by 0.13), a decline of roughly 15%.

Nothing about the company changed in that example. Sales, margins, and customers are the same. Only the required return moved, and the value moved with it. The effect is larger for businesses whose value depends on growth far in the future, because distant cash flows lose more when discounted at a higher rate. It is smaller for businesses that produce steady cash now.

How much of the Treasury increase reaches a given valuation depends on the inputs. One data point suggests the increase is not simply inflation fear. Forbes reported that the 10-year inflation-protected (TIPS) yield rose from 1.90% to 2.94%, which means investors are asking for more real compensation for lending, not only protection against rising prices. Real yields are harder for a valuation to look past.

What can offset a higher rate

A higher discount rate is half of the equation. The other half is the cash flow it is applied to. If inflation lifts prices and the business can pass the increases through to customers, nominal cash flows and growth expectations rise too, and part of the discount rate effect is absorbed. Companies with pricing power, contracted escalators, or recurring revenue tend to hold value better than companies that absorb cost increases in their margins.

Valuation methods also differ in how they treat the risk-free rate. Some appraisers use the spot yield on the valuation date. Others use a normalized rate or adjust the equity risk premium when yields move sharply, on the view that the two inputs tend to offset each other over time. Both approaches are used in practice, and the choice can change a result by a meaningful amount. Owners should ask which approach their appraiser uses and why, rather than finding out when the report arrives.

Markets also move quickly. The 10-year yield eased from its high on October 7 after a Treasury auction drew solid demand, according to CNBC, so the number on the valuation date can differ from the number a week earlier. A valuation is a snapshot, and the date chosen for it matters more when rates are volatile.

Where this shows up for owners

The most direct effect is in sale negotiations. Buyers apply the same logic whether or not they say so: higher required returns, and higher borrowing costs if they use debt, translate into lower offers for the same earnings. Seller expectations anchored to multiples from 2021 or early 2026 can sit well above what a buyer's model supports today.

The effect is also quieter in recurring valuations. A 409A valuation sets the exercise price for employee stock options, and a higher discount rate can lower the common stock value, which affects option pricing. Valuations for gift and estate planning can fall, which some families view as an opening to transfer ownership at a lower value, while buy-sell agreements that reference a formula or a periodic appraisal may reset the price owners pay each other. Each of these is a decision where timing and method matter, and each warrants advice from a tax or legal professional alongside the valuation itself.

What to watch next

Three dates stand out. September inflation data is due on October 14. The Federal Reserve meets October 27 and 28, and futures markets have priced in further increases this year. The Treasury's quarterly refunding announcement, which sets the supply of new government debt, follows in early November. Forbes noted that deficits and heavy borrowing tied to artificial intelligence investment are among the forces keeping long-term yields elevated, and that analysts expect yields to stay under pressure for now. Owners should plan on the assumption that the current rate level, rather than the level of two years ago, is the one buyers and appraisers will use.
