President Donald Trump Claims, "Interest Rates Are Too High, They're Not Appropriate," but the Bond Market Says He's Wrong

Statistically, Wall Street has enjoyed having Donald Trump in the White House. Even though some of the stock market's highest-volatility events have occurred under President Trump (e.g., the COVID-19 crash in February-March 2020 and tariff tantrum in April 2025), the average annual return of the iconic Dow Jones Industrial Average (DJINDICES:^DJI), broad-based S&P 500 (SNPINDEX:^GSPC), and innovation-driven Nasdaq Composite (NASDAQINDEX:^IXIC) are higher under Trump than under most other presidents.

However, the bull market that's thrived under President Trump is at risk of being upended by the start of only the fourth rate-hiking cycle of the 21st century.

President Trump has been critical of the FOMC for raising interest rates

On Sept. 16, Fed Chair Kevin Warsh and 11 other voting Federal Open Market Committee (FOMC) members raised the federal funds target rate by 25 basis points to 3.75%-4.00%. President Trump's handpicked successor to Jerome Powell has repeatedly said that inflation is too high and that the Fed will "deliver price stability."

But President Trump sees things differently. He recently told reporters that:

I'm relying on Kevin [Warsh], but he's got, you know, a very tough board. He's got a board that was put there by a lot of other people. And the interest rates are too high, they're not appropriate.

Criticizing the central bank isn't new for the president. Since the beginning of his second non-consecutive term, he was critical of now-former Fed Chair Jerome Powell and the FOMC for not slashing interest rates. For added context, the FOMC did lower the federal funds target rate six times between September 2024 and December 2025, but not quickly enough for the president's liking.

Trump has repeatedly argued that interest rates should be lowered to 1% or below and has admonished the central bank for hindering America's growth potential.

While it's possible that lower interest rates could fuel America's economy, the bond market believes that would be a terrible idea.

The bond market has a two-word message for President Trump: You're wrong

On paper, it's understandable why businesses and investors aren't too keen about the FOMC kicking off a rate-hiking cycle. Higher interest rates make it costlier to service variable-rate debt.

Additionally, the stock market's No. 1 catalyst, the artificial intelligence (AI) infrastructure build-out, is being financed in part by debt. If the AI data center build-out slows, even marginally, it may spell disaster for the historically expensive bull market that's thrived under Trump.

But it's no coincidence that long-duration Treasury bond yields have ascended to the heavens this year. The 30-year Treasury bond yield has topped 5.5%, a level last seen in 2003, while the 10-year yield -- the benchmark for mortgage rates -- has soared to 5.25%, a 19-year high.

The bond market is sending a very clear message to Wall Street, investors, and even President Trump: rate cuts aren't an option due to three glaring concerns.

1. Trumpflation

For starters, persistently elevated inflation is problematic. While a modest level of inflation is expected in a growing economy, several of the president's policies, including tariffs and the Trump-led Iran war, have become burdensome on consumers.

President Trump's tariffs were designed to promote domestic manufacturing, protect American jobs, and make American-made goods more price-competitive with imported products. Unfortunately, adding duties to unfinished goods (e.g., steel) used to complete the manufacture of products in the U.S. can raise production costs, which are then passed on to consumers.

US Diesel prices hit another record high today at $6.53/gallon, up 74% since the Iran war began.

Meanwhile, the ongoing Iran war has led to the largest modern-day energy supply disruption, pushing diesel prices to record levels.

The more entrenched Trumpflation (inflation that's driven by President Trump's policies) becomes, the more aggressive the Fed will have to be to uproot it.

The parabolic move we're witnessing in long-duration bond yields reflects bond traders' desire to receive higher compensation (i.e., higher yields) amid persistently elevated inflation.

2. Runaway national debt

Soaring long-duration bond yields also signal displeasure with America's unsustainable federal deficits.

In mid-August, U.S. total debt surpassed $40 trillion for the first time, fueled by annual federal deficits ranging from $1.38 trillion to $3.13 trillion over the previous six years. With the exception of 1998-2001, the federal government has run a deficit every year since 1970.

While Donald Trump has repeatedly suggested that lower interest rates are needed to fuel economic growth, the true benefit of lower lending rates is that they would make it considerably easier for the U.S. to service its rapidly growing debt.

However, the bond market has made it clear that lower lending rates aren't on the horizon. Even though the federal government hasn't missed an interest payment and has historically made good on its debt obligations, long-term debt holders want higher yields to offset the added risk of the U.S. continuing to pile on debt.

3. AI hyperscalers are competing for capital

The third reason Donald Trump's calls for rate cuts aren't feasible concerns the aforementioned AI infrastructure build-out.

In speaking with the press after the September FOMC meeting, Fed Chair Kevin Warsh laid part of the blame for rising yields on the competition for capital among hyperscalers:

The surge in capital expenditures, which I referenced in my remarks, is real, and so-called hyperscalers are out in the market raising funding. And so the competition for capital is real, and I think it partly explains the increase in yields.

In simple terms, corporate debt issuances are competing for the same pool of investors as Treasury bond buyers. This competition is pushing up yields, making it impossible for the central bank to seriously consider reducing interest rates.

While the bond market isn't telling us how much Fed Chair Warsh and his colleagues should raise the federal funds target rate, it's made it crystal clear that interest rates aren't high enough and Fed rate hikes are appropriate, given the aforementioned headwinds.
