BofA: Each 1% Fed Hike Adds $95B a Year in Debt Interest

TL;DR: Bank of America analysts put a price on the rate debate this week. Fortune reported on October 20, 2026, that the bank's team wrote: "We estimate that interest expense rises $95 billion a year for every 100bps of Fed hikes." That is the whole estimate. Everything else in the story, from the $40 trillion debt load to the pressure on the new Fed chair, is context for why the White House cares, and for why the number is easier to quote than to use.

What did Bank of America actually say?

The estimate is a rule of thumb. For each full percentage point the Fed adds to its policy rate, the Treasury's yearly interest bill rises by roughly $95 billion, according to Fortune.

The scale of the debt is what makes the number matter. Fortune reports that Treasury payments to service the $40 trillion national debt surpassed $2 trillion for the 2026 fiscal year, per the department's recent announcement.

The story is framed around Kevin Warsh, the new Fed chair, and an administration that has pressed hard for lower rates. Fortune notes that lower rates also, "conveniently, makes the government's own borrowing costs cheaper."

How does the Congressional Budget Office's math compare?

Fortune also cites two Congressional Budget Office scenarios covering 2026 to 2036. They measure something different. The CBO modeled rates running above its baseline for ten years, not a single Fed move, so the two numbers should not be added together or compared line by line.

Scenario (2026-2036)	Added to deficits	Added net interest cost
Rates 150 basis points above baseline	$6 trillion	$4.9 trillion
Rates 50 basis points above baseline	$1.9 trillion	$1.6 trillion

Those figures come from Fortune's account of the CBO projections. Interest compounds. The government borrows more to pay the interest, which then adds to the next year's bill, and that loop is why a modest gap in rates grows into trillions over a decade.

Does a rate cut save $95 billion?

No, and the sources are careful about this. One analysis of the report says the estimate does not mean a rate cut automatically trims the Treasury's bill by $95 billion, or that the Fed should set policy around federal financing costs. The same piece calls the figure an annualized fiscal sensitivity, not a precise prediction of what any single meeting would do to the budget.

There is a second limit. Long-term yields are set by the market, not by the Fed alone. Fortune quotes an analyst saying the 10-year Treasury yield is up about a percentage point this year, among the biggest increases of any major economy, with the most indebted countries generally seeing the biggest rises. Investors, in that reading, are demanding more compensation for the mounting risk. A Fed cut does not automatically reverse that.

Why does this matter if you invest in private markets?

Treasury yields are the benchmark every private deal is priced against. A sponsor projecting a return has to beat the risk-free rate by enough to pay for illiquidity, fees and sponsor risk. If the government's own interest burden keeps pushing yields up, that bar rises with it.

For an accredited investor, three things follow:

• Hurdle rates. Compare any projected return with the Treasury yield for the same duration, not with cash. Our explainer on why the 10-year yield matters to you walks through that comparison.
• Floating-rate income. Higher policy rates lift income for lenders whose loans reset. We covered the mechanics, and the catch, in what a Fed hike would do for BDC income.
• Policy pressure. A White House pushing the Fed toward cuts adds uncertainty about the rate path. For the committee's current stance, see how the Fed turned hawkish but can wait.

The basics of who issues the debt and who sets rates are in how the Treasury and the Fed manage the national debt.

Common mistakes

The first is treating $95 billion as a savings figure. It is an estimate of added cost from hikes. The cut-side effect depends on timing and on how much of the debt reprices, and nobody in these sources puts a number on it. The second is mixing the BofA rule of thumb with the CBO scenarios, which cover different things over different periods. The third is assuming the Fed controls long-term yields. It sets the short-term policy rate, and the market sets the rest.

One gap is worth naming. The sources reviewed for this piece do not say what Warsh plans to do at the next meeting, and nothing here should be read as a rate call.

FAQ

What will Kevin Warsh do to interest rates? The reporting reviewed here does not say. It describes White House pressure for cuts, but no source gives a decision or a timetable. Watch the committee's next statement rather than the headlines about it.

Does a 1% rate cut save the Treasury $95 billion a year? Not automatically. The estimate is stated for Fed hikes, and one analysis cautions that it is a sensitivity, not a forecast. Lags in how debt reprices mean the budget effect arrives gradually.

Will the Fed raise interest rates again in 2026? No source in this piece forecasts that. Our coverage of the Fed's hawkish turn tracks the committee's own signals.

Why should a private-markets investor care about Treasury interest costs? Treasury yields set the benchmark your deal has to beat. Higher government borrowing costs can keep that benchmark elevated, which raises the return a private investment needs to offer.

What to do today

Pull up the projected return on the last private deal you reviewed and compare it with the current 10-year Treasury yield. If the gap does not clearly pay you for the lockup and the sponsor risk, that tells you what to ask next.
