Rising Interest Rates Mean Deficits Finally Matter

The U.S. has long been the lender of last resort to the world. During the emerging-market panics of the 1990s, the global financial crisis of 2007-09 and the pandemic shutdown of 2020, it was the Treasury’s unmatched capacity to borrow that came to the rescue.

Now, the Treasury itself is a source of risk. No, the U.S. isn’t about to default or fail to sell enough bonds at its next auction. But the scale and upward trajectory of U.S. borrowing and absence of any political corrective now threaten markets and the economy in ways they haven’t for at least a generation.

That’s the takeaway from the sudden sharp rise in Treasury yields in recent weeks. The usual suspects can’t explain it: The inflation picture has gotten marginally better, and the Federal Reserve has signalled it’s nearly done raising rates.

Instead, most of the increase is due to the part of yields, called the term premium, which has nothing to do with inflation or short-term rates. Numerous factors affect the term premium, and rising government deficits are a prime suspect.

Deficits have been wide for years. Why would they matter now? A better question might be: What took so long?

That larger deficits push up long-term rates had long been economic orthodoxy. But for the past 20 years, interest-rate models that incorporated fiscal policy didn’t work, noted Riccardo Trezzi, a former Fed economist who now runs his own research firm, Underlying Inflation.

That’s understandable. Central banks—worried about too-low inflation and stagnant growth—had kept interest rates around zero while buying up government bonds (“quantitative easing”). Private demand for credit was weak. This trumped any concern about deficits.

“We had a blissful 25 years of not having to worry about this problem,” said Mark Wiedman, senior managing director at BlackRock.

Today, though, central banks are worried about inflation being too high and have stopped buying and in some cases are shedding their bondholdings (“quantitative tightening”). Suddenly, fiscal policy matters again.

To paraphrase Hemingway, deficits can affect interest rates gradually or suddenly. Investors, asked to buy more bonds, gradually make room in their portfolios by buying less of something else, such as equities. Eventually, the risk-adjusted returns of these assets equalise, which means higher bond yields and lower price/earnings ratios on stocks. That has been happening for the past month.

Sometimes, though, markets can move suddenly, such as when Mexico threatened to default in 1994 and Greece did default a decade later. Even in countries that, unlike Mexico or Greece, borrow in currencies they control, interest rates can become hostage to deficits, such as in Canada in the early 1990s or Italy in the 1980s and early 1990s.

The U.S. isn’t Canada or Italy; it controls the world’s reserve currency, and its inflation and interest rates are mostly driven by domestic, not foreign, factors. On the other hand, the U.S. has also exploited those advantages to accumulate debt and run deficits that are much larger than those of peer economies.

There’s not much sign that this has yet imposed a penalty. Investors still project that the Fed will get inflation down to its 2% goal. At 2.4%, real (inflation-adjusted) Treasury yields are comparable to those in the mid-2000s and lower than in the 1990s, when the U.S. government’s debts and deficits were much lower.

Still, sometimes bad news accumulates below investors’ radar until something brings their collective attention to bear. Could a point come when “all the headlines will be about the fiscal unsustainability of the U.S.?” asked Wiedman. “I don’t hear this today from global investors. But do I think it could happen? Absolutely, that paradigm shift is possible. It’s not that no one shows up to buy Treasurys. It’s that they ask for a much higher yield.”

It’s notable that the recent rise in bond yields came as Fitch Ratings downgraded its U.S. credit rating, Treasury upped the size of its bond auctions, analysts began revising upward this year’s federal deficit, and Congress nearly shut down parts of the government over a failure to pass spending bills.

The federal deficit was over 7% of gross domestic product in fiscal 2023, after adjusting for accounting distortions related to student debt, Barclays analysts noted last week. That’s larger than any deficit since 1930 outside of wars and recessions. And this is occurring at a time of low unemployment and strong economic growth, suggesting that in normal times, “deficits may be much higher,” Barclays added.

Abroad, fiscal policy has clearly begun to matter. Last fall, a proposed U.K. tax cut triggered a surge in British bond yields; the government scrapped the proposal, then resigned. Italian yields have risen since the government last week delayed reducing its deficit to below European guidelines. Trezzi said that for the past decade the European Central Bank had bought more than 100% of net Italian government bond issuance, but that’s coming to an end.

Foreign investors, worried about inflation and deficits, have been selling Italian bonds, while Italian households have been buying, Trezzi said. “With a weakening economy, it is unclear for how long…households can offset the selloff of foreigners.”

Investors looking for U.S. political will to rein in deficits would take note that both former President Donald Trump and President Biden, their parties’ front-runners for the 2024 presidential nomination, have signed deficit-busting legislation and that both of their parties have pledged not to cut the two largest spending programs, Medicare and Social Security, or raise taxes on most households.

They would also notice that the Republican speaker of the House of Representatives was just ousted by rebels in his own party because he had passed a bipartisan spending bill to prevent the government from shutting down. True, the rebels wanted less spending. But shutdowns, Barclays noted, represent “erosion of governance.” This isn’t how a country trying to reassure the bond market acts.

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.

Rising Interest Rates Mean Deficits Finally Matter

Investors ignored deficits when inflation was low. Now they are paying attention and getting worried.

Administration officials have spoken to the airline industry, which has voiced concerns about the rising costs.
