US Interest Rates Are Exposing a Longer Era of Expensive Money

July PCE inflation rose 3.7% from a year earlier, while core PCE increased 3.3%, leaving both above the Federal Reserve’s 2% target.

The Fed kept its policy range at 3.50%–3.75% in July, although three policymakers backed a quarter-point increase.

After Chair Kevin Warsh spoke at Jackson Hole, market-implied odds of a September increase climbed from roughly 35% to around 60%.

Barclays also changed its call and now expects two additional 25-basis-point increases before year-end.

A quarter-point move would lift the target range to 3.75%–4.00%. If policymakers wait, the existing 3.50%–3.75% range would still keep borrowing costs restrictive while inflation remains above target and another increase stays possible later in the year.

Long-term Treasury yields are already reflecting inflation, heavy federal borrowing and the volume of debt coming to market, leaving financing costs elevated even without another immediate Fed move.

Rate cuts are no longer the only direction markets are pricing. Further tightening is back in the debate while inflation remains above target.

Treasury Investors Are Charging More to Finance the United States

The U.S. 10-year Treasury yield was around 4.76% on August 31, while the 30-year had recently climbed above 5% to its highest level since 2007.

Longer-dated government debt is carrying higher yields as federal borrowing remains heavy and inflation stays above the Federal Reserve’s target.

The Fed’s July minutes recorded higher nominal rates as Middle East tensions pushed oil prices up and expectations for tighter policy increased.

Inflation compensation moved only modestly, while expectations for higher policy rates accounted for much of the rise.

CBO projects a $1.9 trillion federal deficit in 2026, with debt held by the public at about 101% of GDP.

Treasury’s August refunding included $125 billion of 3-year, 10-year and 30-year securities and raised about $28.7 billion in new cash from private investors after refinancing maturing debt.

Treasury will raise the maximum size of long-end liquidity-support buybacks from $2 billion to at least $4 billion per operation beginning September 9.

The purchases cover the 10-to-30-year sectors and are designed to improve liquidity in those securities.

Brent crude moved above $90 a barrel on August 31 as U.S.-Iran hostilities intensified, adding fresh energy pressure while Treasury continues to bring large volumes of debt to market.

The United States is still finding buyers for that debt, but the price is higher. Inflation, heavy issuance and renewed expectations for Fed tightening are keeping long-term financing costs elevated.

AI, Power and Infrastructure Are Still Pulling in Capital

U.S. equity funds recorded $22.33 billion of net withdrawals in the week through August 26, while technology funds attracted about $1.81 billion.

U.S. bond funds drew another $7.12 billion, extending their run of inflows to nineteen consecutive weeks.

Anthropic agreed to spend about $45 billion over six years for computing capacity from Nscale’s West Virginia data center, with access to roughly 460 MW of power capacity.

Nvidia also announced a $3.5 billion investment in MediaTek as spending on semiconductors and AI hardware continues.

SLB agreed to pay $4.1 billion for cooling-equipment maker Kelvion as data-center demand expands, while Aggreko moved toward a U.S. IPO after data-center-related revenue nearly doubled.

KKR closed a $19.2 billion infrastructure fund focused on North America and Western Europe, with digital infrastructure and energy transition among its targets.

Higher Treasury yields are giving investors more return in fixed income, but money is still being committed to compute, electricity, cooling and physical infrastructure.

Borrowing costs are elevated, yet projects tied to current demand are continuing to attract financing.

Businesses with weaker cash generation face a harder market as financing stays expensive, while companies tied to power, infrastructure and profitable technology spending continue to secure capital.

Another Fed Hike Would Add to Costs the Market Is Already Carrying

Barclays now expects two additional quarter-point increases in 2026, one in September and another in December, after Chair Kevin Warsh’s Jackson Hole remarks. Market pricing has also moved toward another increase.

Another hike would hit the parts of the market most closely tied to Fed policy first. Short-term Treasury rates, corporate refinancing and consumer credit would move higher, while mortgage costs would stay under pressure.

Longer-dated Treasury yields would still be shaped by inflation, federal borrowing, growth expectations and term premium rather than the policy rate alone. A stronger dollar could also make financing more expensive for foreign borrowers.

If the Fed waits, those costs do not reset. Corporate debt, mortgages and Treasury yields would remain elevated while inflation stays above target and another increase remains possible later in the year.

A softer labour market could change the timing of the next move, but not the restrictive financing conditions already built into the market.

US Interest Rates Are Still Moving Through a Tightening Cycle

Borrowing costs across the U.S. economy are likely to remain elevated even if the Federal Reserve leaves rates unchanged at its next meeting.

Treasury yields, mortgage rates, corporate credit and consumer borrowing are already operating from restrictive levels, while inflation remains above the Fed’s 2% target.

A further increase would lift short-term financing costs again and keep pressure on refinancing, housing and other rate-sensitive parts of the economy.

If policymakers hold, the current rate structure would remain in place, with another increase still possible later in the year.

Capital will continue to favour companies and projects able to carry higher financing costs, particularly across AI infrastructure, power systems and other areas with strong current demand.

Borrowers with weaker cash flow will face tighter conditions as refinancing becomes more expensive.

US interest rates are exposing a longer era of expensive money, with elevated borrowing costs likely to persist until inflation falls far enough for the Fed to begin a sustained easing cycle.
