The yield on the 10-year Treasury bond has
risen steadily this year, as the Iran war rages, government spending worries intensify
and artificial intelligence spending boosts growth.
1.
10-Year
Treasury Yield Hits New High
o The U.S. 10-year Treasury yield rose to 4.7%, its highest level
during President Donald Trump's second term.
o The yield was below 4% before the Iran war began in late
February 2026.
2.
Importance
of the 10-Year Treasury Yield

for mortgages,
corporate loans, auto loans, and other borrowing costs.

rising energy
and food prices
resulting from the Iran war.
o This increases financial pressure on
American households.
5.
Iran
War Not the Only Driver
o Although higher oil prices have raised
inflation concerns, analysts believe other structural factors are playing a
larger role in pushing yields higher.

them to offer higher returns on bonds.
8.
Global
Rise in Government Bond Yields

9.
Growing
U.S. National Debt
o U.S. federal debt has reached nearly $40 trillion, more than double its level a decade ago.
o Increased military spending related to the
Iran conflict is adding to borrowing requirements.
10. Competition for Capital
o Large-scale borrowing by AI companies is
attracting investor funds.
o Other companies must offer higher interest
rates to raise capital.

key measure of economic affordability.
o Lower yields reduce borrowing costs, while
higher yields increase financial burdens on consumers and businesses.
12. Yield Has Risen Sharply Since February
o The 10-year Treasury yield reached its low
for Trump's second term on February
27, 2026.
o It has increased by approximately 0.8 percentage points since then.
13. Pressure on the Federal Reserve
o Markets expect Federal Reserve Chairman Kevin Warsh to maintain a firm stance against
inflation.
o Delayed or insufficient action could keep
long-term interest rates elevated.
14. Persistent Inflation Expectations
o Analysts believe inflation is likely to
remain above the Federal Reserve's target for several more years.
o Persistent inflation expectations continue
to support higher Treasury yields.
The rise in the U.S.
10-year Treasury yield is being driven by a combination of global fiscal deficits, expanding
government debt, strong AI-led investment, and persistent inflation concerns, with the Iran war acting as an
additional catalyst. The increase is raising borrowing costs across the
economy, making mortgages, business loans, and consumer credit more expensive,
thereby complicating the Trump administration's efforts to improve affordability.
President
Trump returned to office promising lower costs across the economy, but an important
interest rate that his administration cites as a barometer of its success recently
hit its highest level of Mr. Trump’s second term.
The
yield on the 10-year Treasury bond, considered one of the most important interest
rates in the world, jumped this week to 4.7 percent, up from less than 4 percent
before the start of the war in Iran in late February. It was 4.6 percent on the
day Mr. Trump returned to the White House in January 2025.
The
yield underpins borrowing costs across debt markets, from corporate bonds to mortgage
loans, and its rise complicates Mr. Trump’s plans to keep costs affordable for companies
and households across the United States.
The
impact is apparent in the housing market. Rising yields have driven up mortgage
rates in recent weeks, dampening hopes that moribund home sales would rebound this
year. The average 30-year fixed-rate mortgage, the most common home loan in the
United States, is now 6.58 percent, Freddie Mac said Thursday. Mortgage rates had
fallen below 6 percent in the week before the first U.S.-Israeli strikes on Iran
in late February.
“This
latest leg up in rates is going to push sales down unless it’s quickly reversed,”
said Nancy Vanden Houten, lead U.S. economist at Oxford Economics. “And it comes
at a time when households are confronting other increased costs for energy and food
due to the effects of the war.”
While
some of the rising yields can be attributed to higher inflation expectations amid
soaring oil prices, analysts said that longer-dated interest rates, like the yield
on the 10-year Treasury note, had been caught in a swirl of higher growth expectations
stemming from the build-out of artificial intelligence infrastructure. The higher
growth, if left unchecked by higher rates, could cause the economy to overheat and
ramp up inflation. Another factor driving up the 10-year yield is investors’ worries
about unsustainable fiscal spending by governments around the world.
“The
Iran war isn’t helping, but it’s not obvious that the 10-year is being driven by
inflation risk,” said Jonathan Hill, an inflation strategist at Barclays.
In
Britain, 10-year gilts — the equivalent term to Treasuries for government debt —
have risen 0.9 percentage points to over 5 percent since the war started, alongside
concerns over the fiscal plans of the new prime minister, Andy Burnham. In Japan,
30-year government bonds have risen 0.7 percentage points, to 2.8 percent, over
the same period, as the government has rolled out hefty spending plans. Concerns
over high government spending also linger in the United States, as the government
seeks to increase its military budget for the war with Iran.
As
governments look to borrow more, investors are demanding a higher return to lend,
and that higher return is reflected in higher interest rates throughout the economy,
analysts said. The U.S. government has nearly $40 trillion in debt outstanding,
more than double the amount 10 years ago.
“All
bond yields are rising, and it is for some of the same reasons,” said Subadra Rajappa,
an interest rate strategist at Société Générale. “It is about domestic debt and
deficits. It’s happening globally.”
Analysts
also pointed to the huge amounts being lent to big technology companies at the forefront
of the A.I. build-out, which is forcing other companies that want to borrow money
to attract investors by increasing the amount they are willing to pay in interest.
Scott
Bessent, the Treasury secretary, has previously pointed to the 10-year bond as a
“barometer” of his success in improving affordability.
“Lower
Treasury borrowing costs mean lower corporate borrowing costs, lower mortgage rates
and lower car payments — which all translates to greater affordability for all Americans,”
he said in a speech in November.
Conversely,
higher treasury yields mean higher borrowing costs for companies and consumers,
hurting affordability.
The
yield had fallen below 4 percent earlier this year, touching its lowest point of
Mr. Trump’s second term on Feb. 27, the day before the United States and Israel
attacked Iran. Since then, the 10-year yield has risen roughly 0.8 percentage points.
Although
analysts said that inflation worries had been largely contained, there remains pressure
on Kevin Warsh, the Federal Reserve chairman, to show his commitment to reining
in the pace of price rises. Traders warn that inaction from the central bank risks
extending those inflation worries over a longer period, potentially pushing yields
on longer-dated Treasury notes even higher.
“The
reality is we are coming up on five and a half years of above-target inflation,”
said Mr. Hill of Barclays, “and the market is already saying we should anticipate
the likelihood of that for additional years, not just months, to come.”
