Rising tensions in the Middle East and escalating conflict involving the US, Israel, and Iran have sent sovereign borrowing costs soaring, pushing US and UK bond yields to levels not seen since the 2008 financial crisis amid fears of prolonged instability, inflation, and fiscal strain.
A sudden rerouting of risk across global markets has pushed sovereign borrowing costs sharply higher as investors price in the economic fallout of the widening conflict involving the United States, Israel and Iran. Government bond yields in both the United States and the United Kingdom have climbed rapidly this month, driven by spikes in oil prices and uncertainty over financing a protracted war effort.
Traders have bid up yields on short- and long-dated Treasuries, with the 10-year note trading near 4.38% and the two-year yield moving into the roughly 3.9% area, according to market data cited by the Chicago Mercantile Exchange FedWatch tool. In the UK the 10-year gilt approached the 5% mark and two-year yields rose sharply, a level of repricing not seen since the 2008 turmoil, reflecting market concerns about persistent inflation and the prospect of higher policy rates.
The immediate catalyst for the repricing has been a pronounced disruption to shipping through the Strait of Hormuz, a route responsible for around one-fifth of global crude flows. Benchmark Brent crude pushed above $110 a barrel this week, briefly touching about $113 before easing, as traders worried that the effective closure of the strait would choke supply and prolong elevated energy costs. According to Axios, market participants are increasingly doubtful that the crisis will be resolved quickly, amplifying risk premia across asset classes.
Economists and market strategists say the shock to energy and commodity channels has forced a rethink of inflation and growth projections. SMBC economists and other forecasters have warned that interruptions to shipments of fertilisers, helium and polymers through Hormuz could feed through into food and technology supply chains, forcing upward revisions to inflation and downward adjustments to GDP expectations, according to reporting by Axios.
The policy implications have been immediate. The rise in oil prices and signs of stickier inflation have increased the chances that central banks will hold policy tighter for longer or even raise rates further. The CME FedWatch probability that the Federal Reserve will deliver at least a 25 basis-point increase by October has swollen to roughly 30%, market gauges show, while the Bank of England’s decision to abandon explicit guidance on cuts has been read as a hawkish signal by investors.
Beyond cyclical monetary responses, market participants are wrestling with the fiscal consequences of sustained military engagement. U.S. public debt has surged past $39 trillion this month, according to AP reporting, and additional defence spending requests, estimated by some officials in the order of hundreds of billions of dollars, would likely be met by increased issuance of government securities. Analysts warn that a heavy supply of sovereign paper, issued to finance conflict costs, could exert further upward pressure on yields.
The bond-market reaction is shaping how Wall Street interprets the evolving geopolitical picture. Traders often treat yields as a real-time gauge of fiscal and geopolitical stress: rising yields are read as a signal of fiscal deterioration and prolonged conflict, while falls are interpreted as tentative stabilisation. That dynamic has prompted a flurry of commentary from prominent economists and former executives. Harvard’s Kenneth Rogoff warned of a “financial shock from the rapid rise in rates,” and former Goldman Sachs chief Lloyd Blankfein cautioned that “While we may not yet feel the storm approaching, the horses inside the fence have already started crying,” remarks that capture growing unease in markets.
Policymakers have explored measures to blunt the oil-price shock. U.S. Treasury officials have publicly discussed the possibility of waiving sanctions on Iranian cargoes already at sea to add supply into the global market, a move Axios reported would represent a significant geopolitical concession intended to cool prices. The administration has also deployed tanker escorts and taken temporary regulatory steps in recent weeks to mitigate disruptions.
Even if physical damage to energy infrastructure is limited, economists caution that the longer the disruption lasts the deeper the second-round effects on inflation and corporate margins will be. The International Energy Agency has suggested that current supply fundamentals remain workable, but political risk and attacks on storage and production facilities would change that calculus rapidly, according to Axios coverage.
The convergence of higher energy costs, swollen fiscal deficits and fast-moving repricing in sovereign bond markets raises the spectre of wider financial stress. Market observers note that a sustained period of rising yields could transmit into higher borrowing costs for households and firms, squeeze emerging markets, and erode risk-taking , a cocktail that, in extreme scenarios, might produce contagion reminiscent of prior crises. For now, investors are monitoring three moving parts: the trajectory of the conflict and Hormuz access, central bank policy responses to inflation, and the pace and scale of sovereign financing needs.

- https://www.axios.com/2026/03/22/iran-war-oil-trump-hormuz-strait-threat – Oil prices have remained volatile, staying above $100 per barrel as the conflict between the U.S. and Iran enters its fourth week, significantly impacting global oil markets. The ongoing war and the effective closure of the Strait of Hormuz—through which a significant portion of the world’s oil is transported—has led to a serious chokehold on supply. On Sunday, Brent crude initially surged to $113 per barrel before settling near $111, reflecting traders’ concerns about the prolonged crisis and ongoing disruption. Former President Trump, on Friday, suggested he might step back from the Iran conflict without resolving the strategic waterway issue, further unsettling markets. Multinational efforts to secure safe oil tanker passage through the strait continue, but no resolution is in sight. Michael McCarthy, CEO of trading platform Moomoo, noted that the expectation of a quick resolution is fading, and investor anxiety is mounting.

- https://www.axios.com/2026/03/21/iran-war-food-oil-shocks – The ongoing Iran war is expected to have long-lasting economic repercussions, even if a ceasefire or safe passage through the Strait of Hormuz is secured. While current disruptions to global oil markets are primarily logistical rather than due to supply destruction, analysts stress that direct attacks on energy infrastructure could have enduring effects. The conflict has already destabilized the flow of vital commodities, especially through the Strait of Hormuz—a key route for global shipping of fertilizer, urea, and helium, vital for agriculture and semiconductor manufacturing. These disruptions are prompting economists, including those from Wall Street and the Federal Reserve, to revise inflation and GDP forecasts upward, anticipating higher inflation and reduced consumer spending. The extent of the economic fallout will depend on the degree of lasting damage to oil and gas infrastructure, according to SMBC economists.

- https://apnews.com/article/6ff73495bae701b5c009d3da5515ca3a – As of March 18, 2026, the U.S. national debt has soared past $39 trillion, marking a historic high and reflecting increasing government spending driven in part by the ongoing U.S.-Israeli war in Iran, which has cost over $12 billion. This surge follows rapid increases earlier in the year — hitting $38 trillion five months prior and $37 trillion two months before that. The Government Accountability Office warns that the growing debt will lead to higher interest costs, reduced business investment, inflated consumer prices, and lower wages. Michael Peterson of the Peter G. Peterson Foundation called the debt growth unsustainable, warning of a potential $40 trillion debt level by the fall elections. The rise in debt is compounded by various fiscal priorities, including tax reform, defense, and immigration enforcement, despite President Donald Trump’s earlier promises to reduce it. In fiscal year 2025, government spending reached $7.01 trillion against $5.23 trillion in revenue, resulting in a $1.78 trillion deficit — a modest $41 billion decrease from the previous year. White House officials attribute the decline to increased tax revenue, streamlined government employment, and anti-fraud efforts. Nevertheless, fiscal analysts urge caution as the debt continues its rapid ascent. ([apnews.com](https://apnews.com/article/6ff73495bae701b5c009d3da5515ca3a?utm_source=openai))
- https://www.axios.com/2026/03/19/trump-iran-oil-sanctions – The U.S. government is considering lifting sanctions on Iranian oil currently at sea as a measure to reduce rising global oil prices, Treasury Secretary Scott Bessent announced on Thursday. This follows a significant 10% surge in Brent crude prices within 24 hours, sparking economic concerns. The Biden administration has previously tried to stabilize prices by offering tanker escorts through the Strait of Hormuz, waiving the Jones Act, and temporarily easing sanctions on Russian oil. The potential move to unfreeze Iranian oil—once a key negotiation point for Iran—would mark a major geopolitical shift, as the U.S. appears willing to make wartime concessions that were previously off the table in diplomacy. Experts suggest that a waiver could redirect some oil bound for China into wider global circulation, underscoring the administration’s commitment to curbing inflationary pressures despite the broader implications.

- https://www.axios.com/2026/03/09/oil-prices-iran-war-strait-hormuz – Amid escalating conflict involving Iran, global oil and gas prices have surged due to the strategic vulnerability of the Strait of Hormuz, a crucial chokepoint through which roughly 20% of global oil passes. This situation has already prompted a 17% increase in U.S. gasoline prices. In addition to oil, about 84% of the Middle East’s polyethylene exports depend on this route, underscoring the ripple effects across industries reliant on plastics, fertilizers, and liquefied natural gas. Key markets, including American consumers, global shipping, and European energy sectors, are facing intensified cost pressures. West Texas Intermediate oil has skyrocketed by 40% in the past week, surpassing $100 per barrel. While historical trends suggest geopolitical disturbances may have short-term impacts on markets, current tensions are causing significant economic unease.

- https://www.axios.com/2026/03/08/trump-oil-prices-iran-fear-strait-hormuz – In a statement on the recent surge in oil prices, U.S. Energy Secretary Chris Wright attributed the spike not to an actual shortage in oil or natural gas, but to market fear and perception. Despite global oil supplies reportedly remaining in surplus, according to the International Energy Agency, geopolitical disruptions such as strikes on Iranian fuel storage, halted production, and a near-complete pause in activity at the Strait of Hormuz have driven up prices. As tensions escalate in the Middle East, notably involving Israeli strikes on Iranian depots, the U.S. administration is also working on measures to curb the impact of rising fuel costs. This price volatility occurs during a sensitive political period leading up to midterm elections, with public concern over the cost of living intensifying. Traders are reacting to perceived risks, bidding up oil prices even in the absence of immediate shortages.
