Higher Interest Rates Not Just for Longer, but Maybe Forever

On Wednesday, Federal Reserve officials surprised markets by signalling interest rates won’t fall as much as previously planned.

The tweak might be more important than it looks. In their projections and commentary, some officials hint that rates might be higher not just for longer, but forever. In more technical terms, the so-called neutral rate, which keeps inflation and unemployment stable over time, has risen.

This matters to any investor, business or household whose plans depend on interest rates over a decade or longer. It could explain why long-term Treasury yields have risen sharply in the past few months, and why stocks are struggling.

The neutral rate isn’t literally forever, but that captures the general idea. In the long run neutral is a function of very slow moving forces: demographics, the global demand for capital, the level of government debt and investors’ assessments of inflation and growth risks.

The neutral rate can’t be observed, only inferred by how the economy responds to particular levels of interest rates. If current rates aren’t slowing demand or inflation, then neutral must be higher and monetary policy isn’t tight.

Indeed, on Wednesday, Fed Chair Jerome Powell allowed that one reason the economy and labor market remain resilient despite rates between 5.25% and 5.5% is that neutral has risen, though he added: “We don’t know that.”

Before the 2007-09 recession and financial crisis, economists thought the neutral rate was around 4% to 4.5%. After subtracting 2% inflation, the real neutral rate was 2% to 2.5%. In the subsequent decade, the Fed kept interest rates near zero, yet growth remained sluggish and inflation below 2%. Estimates of neutral began to drop. Fed officials’ median estimate of the longer-run fed-funds rate—their proxy for neutral—fell from 4% in 2013 to 2.5% in 2019, or 0.5% in real terms.

As of Wednesday, the median estimate was still 2.5%. But five of 18 Fed officials put it at 3% or higher, compared with just three officials in June and two last December.

In 2026, officials project the economy growing at its long-term rate of 1.8%, unemployment at its long-run natural level of 4%, and inflation at its 2% target. Those conditions would normally be consistent with interest rates at neutral. As it happens, officials think the fed-funds rate will end the year at 2.9%—another hint they think neutral has risen.

There are plenty of reasons for a higher neutral. After the global financial crisis, businesses, households and banks were paying down debt instead of borrowing, reducing demand for savings while holding down growth and inflation. As the crisis faded, so did the downward pressure on interest rates.

Another is government red ink: Federal debt held by the public now stands at 95% of gross domestic product, up from 80% at the start of 2020, and federal deficits are now 6% of GDP and projected to keep rising, from under 5% before the pandemic. To get investors to hold so much more debt probably requires paying them more. The Fed bought bonds after the financial crisis and again during the pandemic to push down long-term interest rates. It is now shedding those bondholdings.

Inflation should not, by itself, affect the real neutral rate. However, before the pandemic the Fed’s principal concern was that inflation would persist below 2%, a situation that makes it difficult to stimulate spending and can lead to deflation, and that is why it kept rates near zero from 2008 to 2015. In the future it will worry more that inflation persists above 2%, and err on the side of higher rates with little appetite for returning to zero.

Other factors are still pressing down on neutral, such as an aging world population, which reduces demand for homes and capital goods to equip workers.

So neutral has probably risen since 2019, but not to its pre-2008 level. Indeed, futures markets peg rates a decade from now at around 3.75%.

Of course, this is all just a forecast. If inflation comes down painlessly in the next year, if growth slows abruptly, or if Treasury yields drop, then estimates of neutral will also come down. For now, the evidence suggests the public should get used to higher rates as far as the eye can see.

Former New Hampshire Gov. Chris Sununu delivered a warning to Treasury Secretary Scott Bessent during a recent visit to Washington: Already-high airfares will surge if the war in Iran doesn’t end soon.

Sununu, a Republican who represents some of the biggest airlines as president of the industry group Airlines for America, has for weeks sounded the alarm to Trump administration officials about the economic fallout from high jet fuel prices. The war, Sununu has argued, must come to a close soon, or things will get worse.

Administration officials have gotten the message.

Privately, President Trump’s advisers are increasingly worried that Republicans will pay a political price for the rising fuel costs, according to people familiar with the matter. Many of those advisers are eager to end the war, hoping prices will begin to moderate before November’s midterm elections.

The fallout from the U.S.-Israeli attack in late February has slowed traffic through the Strait of Hormuz, a vital shipping lane, triggering a sharp increase in oil, gasoline and jet-fuel prices.

That means consumers are grappling with high costs ahead of the summer travel season, as they consider vacation plans.

Sixty-three per cent of Americans said they put a great deal or a good amount of blame on Trump for the increase in gas prices, according to a new poll conducted by NPR, PBS and Marist.

More than 8 in 10 Americans said struggles at the gas pump are putting strain on their finances.

Jet-fuel prices roughly doubled in a matter of weeks after the war began, and they have remained high. Airlines have said that will add billions of dollars of additional expenses this year, squeezing profit margins.

U.S. airlines spent more than $5 billion on fuel in March—up 30% from a year earlier, according to government data.

Carriers have been raising ticket prices, hoping to pass the cost along to consumers, and they are culling flights that will no longer make money at higher price levels.

In March, the price of a U.S. domestic round-trip economy ticket rose 21% from a year earlier to $570, according to Airlines Reporting Corp., which tracks travel-agency sales.

So far, airlines have said the higher fares haven’t deterred bookings and they are hoping to recoup more of the fuel-cost increases as the year goes on.

Earlier this week, Trump said the current price of oil is “a very small price to pay for getting rid of a nuclear weapon from people that are really mentally deranged.”

Secretary of State Marco Rubio told reporters that if Iran got a nuclear weapon, the country would have more leverage to keep the strait closed and “make our gas prices like $9 a gallon or $8 a gallon.”

Trump has taken steps in recent days to bring the war to an end. Late Tuesday, the president paused a plan to help guide trapped commercial ships out of the Strait of Hormuz, expressing optimism that a deal could be reached with Iran to end the conflict.

Crude oil prices fell below $100 a barrel on Wednesday, after reports that Iran and the U.S. are working with mediators on a one-page framework to restart negotiations aimed at ending the conflict and opening the strait.

Sununu said Trump administration officials are conscious of the economic fallout from the war: “They get it…and I think that’s why they’re trying to get through the war as fast as they can.”

But he cautioned that it could take months for prices to return to prewar levels.

“Ticket prices won’t go down immediately” after the strait is fully reopened, Sununu said. “You’re looking at elevated ticket prices through the summer and fall because it takes a while for the prices to go down.”

Since the initial U.S.-Israeli attack in late February, Sununu has met in Washington with National Economic Council Director Kevin Hassett, representatives from the Transportation Department and senior White House officials.

A White House official confirmed that Hassett and Sununu have discussed the effect of increased fuel prices on the airline industry. The official said the conversation touched on how the industry can mitigate the impact of high jet fuel prices on consumers.

“The president and his entire energy team anticipated these short-term disruptions to the global energy markets from Operation Epic Fury and had a plan prepared to mitigate these disruptions,” White House spokeswoman Taylor Rogers said, pointing to the administration’s decision to waive a century-old shipping law in a bid to lower the cost of moving oil.

Rogers said the administration is working with industry representatives to “address their concerns, explore potential actions, and inform the president’s policy decisions.”

A Treasury Department spokesman pointed to Bessent’s recent comments on Fox News that the U.S. economy remains strong despite price increases. The spokesman said Treasury officials have met with airline executives, who have reaffirmed strong ticket bookings.

“We’re cognizant that this short-term move up in prices is affecting the American people, but I am also confident, on the other side of this, prices will come down very quickly,” Bessent told Fox News on Monday.

The war has already contributed to one casualty in the industry: Spirit Airlines. Company representatives have said they were forced to close the airline because the sustained surge in jet-fuel prices derailed the company’s plan to emerge from chapter 11 bankruptcy.

The Trump administration and Spirit failed to come to an agreement for the company to receive a financial lifeline of as much as $500 million from the federal government.

Transportation Secretary Sean Duffy has argued that the Iran war wasn’t the cause of Spirit’s demise, pointing to the company’s past financial struggles, as well as the Biden administration’s decision to challenge a merger with JetBlue.

Other budget airlines have also turned to the federal government for help since the U.S.-Israeli attack. A group of budget airlines last month sought $2.5 billion in financial assistance to offset higher fuel costs, and they separately wrote to lawmakers asking for relief from certain ticket taxes.
