NextFin News - The U.S. Treasury market is confronting a dual-front assault as the military confrontation with Iran, which began with a strike on February 28, enters a second month of fiscal and inflationary pressure. Yields on the 10-year Treasury note briefly touched 4.5% on Tuesday, a level not seen since last summer, as investors began to price in the staggering costs of an extended conflict that has already upended global energy markets and strained the federal budget.
The Pentagon is currently seeking more than $200 billion in supplemental funding from Congress to sustain operations against Iran. This request comes on top of a $900 billion defense bill already signed for fiscal year 2026 by U.S. President Trump. The fiscal strain is further compounded by a recent Supreme Court ruling that invalidated the administration’s use of emergency powers to impose certain tariffs, potentially forcing the government to issue $175 billion in refunds to importers. With the national debt standing at a record $39 trillion, the prospect of a widening deficit is no longer a theoretical concern for bondholders.
Andrew Husby, a senior economist at BNP Paribas, warned that the U.S. deficit could surge from just below 6% of GDP to over 8% if these war-related costs and revenue shortfalls persist. Husby, who typically maintains a data-driven, neutral-to-cautious stance on fiscal policy, noted that while markets often wait for actual legislation before reacting, the current trajectory is one that bond investors are increasingly unwilling to ignore. His assessment suggests that the "peace dividend" expectations held by some on Wall Street may be premature.
The surge in yields is not solely a product of government borrowing. Energy prices have spiked as the conflict threatens the Strait of Hormuz, through which 80% of Asia’s oil and liquefied natural gas (LNG) flows. This energy shock has reignited inflation fears, leading traders to abandon hopes for near-term Federal Reserve rate cuts. Bill Campbell, a portfolio manager at DoubleLine Capital, observed that the cumulative effect of these "little costs" is beginning to weigh heavily on market sentiment. DoubleLine, led by Jeffrey Gundlach, has historically been vocal about the risks of rising U.S. debt levels, and Campbell’s current outlook aligns with the firm’s long-standing skepticism regarding fiscal sustainability.
However, this bearish view is not a universal consensus. Mike Cudzil, a portfolio manager at PIMCO, offers a counter-narrative, suggesting that the oil price shock will eventually act as a "tax" on consumers, slowing economic growth enough to forestall further rate hikes. PIMCO has been adding longer-dated debt to its portfolios, betting that the Fed will eventually be forced to cut rates later this year to support a flagging economy. This perspective views the current yield spike as a buying opportunity rather than the start of a structural collapse in the bond market.
The Treasury Department may soon be forced to pivot its issuance strategy if the 30-year yield, currently near 4.95%, climbs toward the 5.25% mark. Such a move would likely involve shifting more borrowing toward short-term bills to avoid locking in high long-term interest costs. For now, the market remains in a state of high-tension equilibrium, waiting to see if the conflict escalates into a broader regional war or if diplomatic channels can provide a reprieve before the fiscal burden becomes unsustainable.
