The Rate the Fed Doesn't Set: Why Long Yields Now Drive Deal Math

On Friday morning, Kevin Warsh will deliver his first Jackson Hole keynote as chair of the Federal Reserve, and markets will parse every sentence for a signal about a September rate cut. For business owners and dealmakers, the more consequential number has been moving quietly in the background: the 30-year Treasury yield has climbed to roughly 5.2 percent, near multi-year highs, while short rates have gone nowhere. That divergence, more than anything said in Wyoming, is reshaping how deals get priced.

Two Rates, Moving Apart

The federal funds rate, the overnight rate the Fed controls directly, sits in a target range of 3.5 to 3.75 percent. The Fed has not cut at all in 2026, inflation has now run above the 2 percent target for more than five years, and the committee's own projections imply just one quarter-point cut this year. Futures pricing has swung through August between treating a September cut as likely and treating a hold as the base case, which tells you how little conviction the market has about the short end.

The long end has been more decisive, and it has moved in the direction borrowers did not want. Bond investors spent the summer selling long-dated Treasuries, pushing the 30-year yield toward 5.2 percent and steepening the yield curve sharply. The selling reflects forces the Fed does not directly control: heavy Treasury issuance to fund federal deficits, a wave of corporate borrowing for AI infrastructure, elevated energy prices, and investors demanding more compensation, known as term premium, for holding long bonds in an uncertain fiscal environment.

This is the distinction that matters for anyone financing a transaction. The Fed sets one rate at the very short end of the curve. Everything further out is set by supply and demand, and this summer supply has been winning.

A New Chair With a Balance Sheet Agenda

Warsh takes the podium Friday at a symposium themed around financial innovation and payments, but investors will listen for two other things: how he weighs stubborn inflation against a softening economy, and what he intends to do with the Fed's balance sheet.

The second question matters more for the long end. Warsh has argued for years that the Fed's holdings of Treasuries and mortgage securities are too large, and he has floated a formal accord between the Fed and the Treasury Department to coordinate shrinking them. Analysts expect any Warsh-era balance sheet plan to tilt the Fed's remaining holdings toward shorter maturities, a reversal of the maturity-extension programs of the 2010s. When the central bank holds fewer long bonds, private investors must absorb more of them, which tends to push long yields higher. One published estimate puts the effect of a $600 to $700 billion reduction at 15 to 20 basis points of additional long-term yield, with the curve steepening further in the process.

The Treasury Department is already leaning against that pressure. Secretary Bessent has stepped up buybacks of longer-dated bonds in recent weeks, an unusual posture that amounts to one arm of the government supporting the market the other arm may stop supporting. The tug of war leaves a plausible path where the Fed cuts short rates in September while long yields hold near current levels or drift higher. Anyone waiting for all interest rates to fall together may be waiting for something the current policy mix is not designed to deliver.

Which Rate Prices Your Deal

For owners and buyers, the practical question is which end of the curve a given piece of capital is priced from.

Floating-rate acquisition debt tracks the short end. Most leveraged buyouts and sponsor-backed acquisitions in the middle market are financed with loans priced at SOFR plus a spread, and SOFR moves with the fed funds rate. If the Fed cuts in September, buyers using floating-rate debt see their cash interest cost fall within weeks. That is real relief, and it explains why deal professionals watch FOMC meetings closely.

Fixed-rate, longer-tenor capital prices off Treasuries. Insurance company private placements, commercial mortgages, equipment finance, and most fixed-rate refinancings are quoted as a spread over the 5, 10, or 30-year Treasury. Those costs have risen this summer even as cut expectations firmed. A business owner refinancing a building or locking long-term debt is borrowing in the market Warsh's balance sheet views affect most.

Valuation math also keys off the long end. Discounted cash flow analysis starts from a long-term risk-free rate; when the 30-year rises, discount rates rise and the present value of future earnings falls. The effect is largest for businesses whose value sits furthest in the future, which is why growth-story valuations are more sensitive to the long bond than to the Fed's next meeting. Capitalization rates on real estate move the same way, which flows into appraisals and sale-leaseback pricing for any company that owns its facilities.

Even seller financing feels it. When a seller carries a note, the coupon gets negotiated against what the seller could earn holding Treasuries instead. A 5 percent long bond resets that conversation.

The Window Question

Sellers preparing for a process should read the curve rather than the calendar. A September cut would likely improve buyer sentiment and modestly cheapen floating-rate financing, both helpful. It would do little for the fixed-rate money that anchors valuation models, and a process launched this fall will close into whatever the long end looks like next spring. The right response is not to time the FOMC but to make the business itself financeable: durable earnings, clean working capital, and documentation that survives diligence hold their value in any rate environment.

Buyers face a structuring decision more than a timing decision. A steep curve rewards borrowing short and floating, but it also raises the cost of being wrong if inflation keeps the Fed from following through. Rate caps and swaps deserve a fresh look while the market still prices cuts ahead. And any acquirer modeling an exit three to five years out should test what a persistent 5 percent long bond does to exit multiples, not just to interest expense.

Owners with fixed-rate maturities coming due in 2027 and 2028 have the least room to wait. Those refinancings price off the long end, and the long end has been going the wrong way while everyone watched the Fed.

What to Watch After Wyoming

Three follow-on events will tell you whether Friday's message sticks. The FOMC meets September 15 and 16, and the accompanying projections will show whether the committee still expects only one cut this year. Any formal announcement on balance sheet policy, particularly the maturity composition of holdings, would move the long end directly. And the Treasury's quarterly refunding decisions, including whether buybacks of long bonds continue or expand, will show how hard the government is willing to lean against the steepening.
