Key Takeaways
- Fiscal Strain & Yields Surge:Record US government debt, exacerbated by the Iran war and tax cuts, has pushed long-term Treasury yields to a 19-year high, reflecting profound investor concern over fiscal sustainability and driving up borrowing costs across the economy.
- Inflationary Pressures & Fed’s Dilemma:The Iran war has triggered a significant supply shock in energy markets, sending fuel and related consumer prices soaring. Despite embedded inflation risks, the Federal Reserve’s inaction on interest rates is fueling market jitters and calls into question its commitment to price stability.
- Policy Ineffectiveness & Dwindling Confidence:Treasury Secretary Bessent’s attempts to calm markets through debt purchase pledges and deficit reduction promises have largely failed, leading to a weaker dollar and a notable erosion of consumer and investor confidence in the administration’s economic stewardship.
Almost two years since Donald Trump clinched the election on a platform promising fiscal rectitude and a crackdown on inflation, his administration’s trajectory, marked by the Iran war and substantial tax cuts, has delivered a starkly different economic landscape: record-high national debt, spiraling energy costs, and a tightening grip of punishing mortgage rates.
The bond market, often the first harbinger of underlying economic stress, reacted sharply. Investors aggressively pushed yields on long-term US debt to a 19-year high on Tuesday. This dramatic move underscored growing alarm over the nation’s burgeoning public borrowing and the war’s potent inflationary fallout. The surge in yields signals a rising risk premium demanded by investors to hold US sovereign debt, reflecting skepticism about the government’s ability to manage its finances sustainably. Higher Treasury yields, in turn, serve as a benchmark, ratcheting up borrowing costs for corporations, consumers, and states alike, with direct implications for capital investment and economic expansion.
In an immediate attempt to staunch the bleeding, Trump’s Treasury secretary, Scott Bessent, intervened a day later, unveiling a program to “at least double” purchases of long-term debt and promising imminent announcements on concrete steps to tackle the deficit. This market intervention, interpreted by many as a form of quantitative easing originating from the Treasury rather than the Federal Reserve, was intended to inject liquidity and depress yields. However, its immediate impact was muted; it did little to lower Treasury yields and, perhaps more tellingly, pushed the dollar lower against a basket of major currencies. A weaker dollar reflects a loss of international confidence in the US fiscal outlook and could further fuel import-driven inflation.
Bessent, insistent on Thursday that markets had “gotten ahead of themselves,” echoed President Trump’s assertion that the economy is “booming,” evidenced by recent stock market highs. Yet, as Eswar Prasad, economics professor at Cornell University, observed, “The president’s fulminations and his administration’s efforts to intervene in currency and bond markets have an air of desperation, which is only making matters worse and turning market sentiment in an even more unfavourable direction.” This sentiment highlights the critical importance of credibility and consistent policy messaging in financial markets, where perceived desperation can be more damaging than the underlying economic data itself.
The market tumult vividly underscores how Trump’s ambitious economic agenda risks unravelling just as November’s midterm elections loom. Polls now indicate a significant shift, with Democrats leading the president’s Republicans on their handling of the economy – a stark reversal from initial perceptions.
The nation’s fiscal ledger paints a grim picture. Government debt hit an unprecedented $40 trillion this week, with borrowing rising at its fastest pace outside the pandemic era. This accelerated accumulation is a direct consequence of federal spending outpacing income, a trend exacerbated by the Iran war’s exigencies and structural fiscal imbalances. The Congressional Budget Office (CBO) data shows the deficit fell only marginally in the 2025 fiscal year, from 6.4 per cent of GDP in 2024 to 5.8 per cent. Critically, Trump’s signature tax cuts are projected to add substantially to deficits in the years ahead, despite simultaneous cuts to vital social safety-net programmes, including Medicaid health coverage and food assistance for America’s most vulnerable. Diane Swonk, chief economist at KPMG US, succinctly captured the predicament: “We continue to outspend — [and] the spending demands are even greater with the war.”
Bessent, who has pledged to reduce the deficit to 3 per cent of GDP by the end of Trump’s second term, optimistically insisted on Thursday that there was a “very, very good chance” it had now peaked. His rationale rested on projected economic growth and future tariff duties boosting revenues. However, Michael Strain, director of economic policy studies at the American Enterprise Institute, a right-leaning think-tank, cautioned that such deficit reduction would inevitably entail tough political choices for Trump, including potentially unpopular cuts to major entitlement programs like Medicare and Social Security. “I hope what secretary Bessent is saying is true,” Strain remarked, “But there are some major questions about how it might work.” The Treasury did not respond to a request for comment, leaving market participants to weigh the feasibility of these ambitious fiscal targets against the political realities.
Beyond the escalating debt mountain, the ongoing Iran war is proving to be a potent inflationary accelerant, torpedoing the president’s earlier promises to halve energy prices and drive down basic consumer costs. The conflict has triggered a significant supply shock in global oil markets. Petrol prices have jumped by approximately 40 per cent since the war erupted, reaching $4.11 a gallon on Friday. Diesel, the indispensable fuel that powers the US economy’s vast logistics and transportation networks, has seen a similar surge, climbing to $5.58 a gallon. This cost-push inflation for freight and logistics quickly translates into higher prices for virtually all consumer goods.

The average diesel price in Trump’s second term is now notably higher than during Joe Biden’s tenure, illustrating the profound impact of current geopolitical events. Concurrently, mortgage rates are also rising briskly, even if they currently remain below the peak seen under Trump’s predecessor. The widely followed 30-year fixed mortgage rate this week hit 6.65 per cent, a significant increase from 5.98 per cent recorded before the war in late February. This upward trajectory in borrowing costs for housing directly impacts affordability, further straining household budgets already reeling from higher fuel and food prices. Jaret Seiberg of TD Securities observed, “As rates dropped over the final quarter of 2025 and the first quarter of 2026, the political pressure on the administration to tackle housing affordability was less,” adding that the White House now has “no choice” but to focus on bringing down rates “even if the relief is temporary.”

Annual consumer price inflation (CPI) reached a three-year high of 4.2 per cent in May before moderating slightly to 3.4 per cent in July. However, Federal Reserve officials remain deeply concerned that persistently elevated inflation risks becoming embedded in the economy, potentially leading to a wage-price spiral and eroding long-term purchasing power. Despite these risks, the Fed has controversially opted against raising interest rates, a decision that has fueled market jitters and raised questions about their willingness, or ability, to effectively contain inflationary pressures. This perceived hesitancy from the central bank adds another layer of uncertainty for investors, who typically rely on the Fed for clear guidance on monetary policy and price stability.
The disruption to Middle Eastern energy supplies from the war has dramatically overshadowed the modest growth in the US’s own oil output, which Trump had championed as a key strategy to curb domestic prices. Art Berman, a Houston-based energy consultant, lamented that Trump’s war had effectively “squandered” the US’s hard-won energy advantage. “My belief is that this administration — and probably every administration back to Franklin Roosevelt — is energy blind. They just don’t get any of this stuff,” Berman contended. While the US remains the world’s largest oil producer, the federal Energy Information Administration (EIA) expects output to rise by just 200,000 barrels a day this year. This incremental gain pales in comparison to the estimated 20 million barrels per day of oil flows through the Strait of Hormuz that have been shut in from the Middle East during Trump’s war, starkly illustrating the geopolitical vulnerability of global energy markets.
The cumulative burden of burgeoning national debt, high borrowing costs, and the persistent strain of costly fuel and food has predictably weighed heavily on US consumer sentiment. The University of Michigan’s consumer sentiment index hovers at record lows, a critical indicator given that consumer spending accounts for roughly 70% of US GDP. Polls consistently show voters now believe they are worse off under Trump’s economic stewardship, directly linking economic reality to political perception.

Despite these headwinds, overall economic growth remains resilient, largely thanks to robust American consumer spending and a surge in investment by Big Tech firms pouring capital into AI infrastructure. However, GDP expansion last year of 2.1 per cent and an annualised rate of 1.5 per cent in the second quarter of 2026 are well below the ambitious 5-6 per cent predicted by commerce secretary Howard Lutnick or the 3 per cent targeted by Bessent. On Thursday, the Treasury secretary reiterated his conviction that the US was still poised to “grow our way out” of its formidable debt hole, a strategy that heavily relies on sustained, high-level economic expansion to increase tax revenues and reduce the relative debt burden.

Market Impact
The confluence of escalating debt, persistent inflation, and policy uncertainty portends continued volatility across financial markets. Investors should brace for sustained pressure on fixed-income assets as higher Treasury yields become the norm, potentially triggering a broader re-evaluation of sovereign credit risk and corporate debt spreads. Equity markets, while buoyed by tech-driven growth, face headwinds from compressed corporate margins due to rising input costs, higher borrowing expenses, and the threat of decelerating consumer spending. The dollar’s weakening trend, reflective of wavering confidence in US fiscal management, could further complicate international trade and capital flows. Furthermore, the Federal Reserve’s cautious stance on interest rates, amidst mounting inflationary pressures, creates an environment of policy unpredictability, increasing the risk of stagflation where slow growth coexists with high inflation. Corporations will need to focus on supply chain resilience and cost management, while consumers face an erosion of purchasing power, making prudent financial planning more critical than ever.
