US Treasury Secretary Defends Economic Costs of Iran War as Worthwhile for Long-Term Security

"I think we will look back and say that it was — I don't know the number of days, whether it's 50 or 100 or more — for 50 years of stability." That was Treasury Secretary Scott Bessent on Meet the Press on March 22, defending Operation Epic Fury's economic fallout as an acceptable trade [1]. In a separate interview, he distilled the argument further: the conflict with Iran would involve a "bit of pain" but was worthwhile for long-term security [2].

Six weeks into the largest US military engagement since Iraq, the tab is already enormous — and the question of who absorbs the pain, and whether the promised security will materialize, is far from settled.

The Direct Cost: $30 Billion and Counting

The Center for Strategic and International Studies estimated that the war cost the US Treasury $16.5 billion in its first 12 days alone [3]. The Pentagon confirmed $11.3 billion in spending during the first six days at a March 11 briefing to the Senate Appropriations Subcommittee on Defense [4]. Congressional sources reported daily costs approaching $1 billion to $2 billion, with Republican lawmakers privately expressing alarm at the pace of expenditure [4].

By late March, Defense Secretary Pete Hegseth announced a forthcoming supplemental request to Congress for $200 billion to cover operations, ammunition replenishment, and contingency reserves [5]. The munitions burn rate has been extraordinary: $5.6 billion in ordnance was expended in the first two days, including 1,250 defensive and offensive weapons in the first 36 hours [6].

For context, the first 30 days of the 1991 Gulf War cost roughly $10.2 billion in inflation-adjusted terms, and the 2003 Iraq invasion's opening month ran approximately $8.6 billion [7]. The Iran conflict's first-month costs of roughly $30 billion represent a threefold increase over the most expensive comparable operation in modern US history.

The Strait of Hormuz: The World's Most Expensive Chokepoint

The economic damage extends far beyond the Pentagon's ledger. Iran's closure of the Strait of Hormuz on March 4 disrupted roughly 20% of global oil supplies — what the International Energy Agency called "the largest supply disruption in the history of the global oil market" [8].

The strait normally handles roughly 20 million barrels of oil equivalent per day. Saudi Arabia routes 6.3 million barrels per day through it, Iraq 3.3 million, the UAE 2.9 million, and Kuwait 1.7 million [9]. Qatar exports 4.1 million barrels of oil equivalent in liquefied natural gas through the same corridor [9]. The disruption was not partial: production from these Gulf states collectively dropped by 10 million barrels per day within two weeks of the closure [8].

Brent crude surged past $120 per barrel on March 4, the day of the closure, before moderating to around $100 per barrel in mid-March [6]. The Federal Reserve Bank of Dallas modeled three closure scenarios [10]:

• One-quarter closure (roughly 90 days): Oil at $98/barrel in Q2, GDP reduced by 2.9 percentage points annualized in that quarter, full-year growth cut by 0.2 points.
• Two-quarter closure: Oil at $115/barrel by Q3, full-year growth cut by 0.3 points, with Germany and other energy-dependent economies at risk of recession.
• Three-quarter closure: Oil reaching $132/barrel by Q4, full-year US growth cut by 1.3 percentage points — a figure that would push the economy to the brink of contraction.

The Dallas Fed described the disruption as "three to five times larger" than any previous geopolitical oil shock, including the 1973 Arab embargo and the 1979 Iranian Revolution [10].

The Inflation Surge: Who Pays for the 'Bit of Pain'

The Consumer Price Index rose 0.9% in March alone — the largest monthly jump since the post-COVID price surge — and stands 3.3% above the prior year [11]. Gasoline prices drove much of the increase, with the CPI gasoline index up 18.9% year-over-year [12]. California prices crossed $5 per gallon during the second week of March [11].

Bessent's framing of a "bit of pain" obscures a fundamental distributional question. Higher gasoline prices function as a regressive tax: lower-income households spend a significantly larger share of their budgets on energy and transportation than wealthier households [13]. A family in the bottom income quintile that commutes by car and heats with natural gas faces a materially different "bit of pain" than a hedge fund manager — a background Bessent knows well from his career at Soros Fund Management.

CNBC reported that economists are characterizing the oil shock as deepening America's "K-shaped economy," where the costs of the conflict concentrate on lower-income and middle-income households while financial assets held disproportionately by wealthier Americans are cushioned by defense-sector stock gains and commodity hedges [14]. Goldman Sachs raised its probability of recession over the next 12 months to 30%, driven primarily by the oil price surge [13].

The Center for American Progress noted that gasoline price spikes erode disposable income for those least able to absorb it, reducing spending on food, rent, and other essentials [13]. Barclays estimated that if oil averages $100 for the year, global headline inflation would spike 0.7 percentage points higher to 3.8%, while growth would fall 0.2 points to 2.8% [8].

The Missing Cost-Benefit Analysis

Bessent's "50 years of stability" claim rests on unstated assumptions. No formal cost-benefit analysis has been published by the Treasury Department, the National Security Council, or any allied government comparing the economic cost of the war to the security gains of degrading Iran's nuclear and military infrastructure.

Senator Ron Wyden, the ranking Democrat on the Senate Finance Committee, wrote to Bessent on April 9 demanding an accounting of the Treasury Department's pre-war economic preparations. The letter asked what modeling Treasury conducted before the conflict, what contingency plans existed for the Strait of Hormuz closure, and whether the department had coordinated with allies on economic resilience measures [15].

The administration's case rests on an implicit argument: Iran was approaching nuclear weapons capability, and military action now prevents a far costlier nuclear-armed Iran later. But the timeline assumptions underlying that argument have not been made public, and intelligence estimates of Iran's nuclear breakout window have varied significantly over the past two decades.

Bessent has framed the war in maximalist terms. On social media, he wrote that "Iran is the head of the snake for global terrorism, and through President Trump's Operation Epic Fury, we are winning this critical fight at an even faster pace than anticipated" [16]. On Fox Business, he accused Iran of attempting to create "economic chaos" and forecast further escalation [17]. Neither statement engaged with the economic costs his office is responsible for managing.

The Historical Pattern: Projected vs. Actual

Treasury Secretaries have a poor track record of accurately forecasting wartime economic costs to the public. Before the 2003 Iraq invasion, OMB Director Mitch Daniels estimated total costs at $50 billion to $60 billion [7]. White House economic adviser Lawrence Lindsey suggested an "upper bound" of $100 billion to $200 billion — and was pushed out of his position for the estimate [7]. The actual cost exceeded $600 billion in direct appropriations and reached $3 trillion when economists Joseph Stiglitz and Linda Bilmes incorporated long-term veteran care, interest on war debt, and macroeconomic effects [7].

The pattern of underestimation is consistent. Initial cost projections serve a political function — making conflict appear affordable — that is in structural tension with accurate forecasting. Bessent's refusal to offer a specific cost figure, combined with his assurance that whatever the number is, it's a bargain, follows the same rhetorical template.

What the Administration Isn't Modeling

Several categories of cost appear absent from the official framing.

Cyberattacks on critical infrastructure. Iran shifted from episodic cyberattacks to a sustained campaign against US critical infrastructure within days of the first strikes. The CSIS reported that security researchers tracked over 60 active threat groups aligned with the conflict, 53 operating on the pro-Iranian side [18]. Iran-linked hackers caused operational disruptions at multiple US oil, gas, and water facilities [19]. Iranian drones struck two Amazon Web Services data centers in the UAE, causing regional service outages [20]. A GPS spoofing campaign affected more than 1,100 vessels in the Persian Gulf within 24 hours [20].

Proxy retaliation. Houthi-controlled Yemen resumed attacks on commercial shipping in the Red Sea, forcing major container lines including Maersk, CMA CGM, and Hapag-Lloyd to reroute around the Cape of Good Hope, adding weeks to transit times and increasing shipping costs globally [8].

Supply chain cascades. The disruption goes beyond oil. Up to 30% of internationally traded fertilizers normally transit the Strait of Hormuz [21]. QatarEnergy's shutdown affected global helium and fertilizer markets [6]. Over 46,000 flights into and out of the Middle East were canceled [6]. More than 500 oil tankers and 500 container ships were trapped at the strait as of mid-March [6].

Infrastructure damage. Rystad Energy's chief economist Claudio Galimberti has warned that the most consequential escalation risk involves targeting of refineries, LNG terminals, and power plants — facilities that take months or years to rebuild [22]. Unlike temporary supply disruptions, infrastructure damage creates prolonged shortages that outlast any ceasefire.

Allies Bearing Costs They Didn't Choose

The United States launched Operation Epic Fury with minimal consultation of its European and Asian allies [23]. The reactions have ranged from cautious support to open condemnation.

Spain's Prime Minister Pedro Sánchez stated his government's "rejection" of "the unilateral military action of the United States and Israel, which represents an escalation and contributes to a more uncertain and hostile international order" [24]. France's President Emmanuel Macron warned that "military action conducted outside international law risks undermining global stability" [23]. Poland's defense minister noted that a prolonged Middle East conflict could jeopardize arms supplies to Ukraine and boost Russia through higher energy revenues [24].

Asian economies face the steepest costs. The United Nations Development Programme estimated that military escalation in the Middle East could cause output losses between $97 billion and $299 billion in the Asia-Pacific region, with 8.8 million people at risk of falling into poverty [25]. The European Central Bank warned that a prolonged conflict would likely trigger stagflation and push Germany and Italy into technical recession by year-end [24].

Trump rebuked NATO allies and Indo-Pacific partners — Japan, South Korea, and Australia — for refusing to join US-led operations to reopen the Strait of Hormuz, calling their decision a "very foolish mistake" [24]. Both China and European NATO nations rejected the call for military support [24]. The gap between Bessent's framing of "long-term security" as a collective benefit and the actual distribution of decision-making authority is the central tension in alliance management.

The Council on Foreign Relations described Europe's position as constrained by "relatively limited strategic weight in the conflict itself," leaving European governments unable to meaningfully influence outcomes while absorbing energy price shocks they had no role in creating [23].

The Steelman Case for Underestimation

Several independent analyses suggest the administration's cost framing is systematically incomplete.

Oxford Economics modeled a scenario in which the conflict persists for several months, with oil reaching $130 per barrel before declining — a price level that would push inflation above 4% and materially tighten financial conditions [22]. Bloomberg reported that analysts are discussing $130-$135 scenarios in more severe escalation paths [22].

The Chatham House assessment drew a distinction between a "painful but manageable shock" and a scenario that "risks tipping the global economy into a prolonged period of instability" [22]. The difference hinges on duration and escalation — precisely the variables that are hardest to predict in wartime and that official cost estimates tend to assume will resolve favorably.

Representative Brendan Boyle requested that the Congressional Budget Office analyze costs under several scenarios, including the war lasting longer than four to five weeks and the deployment of US ground troops in Iran [4]. The CBO's analysis has not yet been published. Without it, the administration's assurance that the costs are worthwhile rests on its own assertions rather than independent verification.

Nouriel Roubini, the economist known for forecasting the 2008 financial crisis, outlined escalation scenarios on Bloomberg that included sustained Hormuz closure, proxy activation across multiple theaters, and credit market contagion — second- and third-order effects that do not appear in the Pentagon's direct cost accounting [22].

What '50 Years of Stability' Would Require

Bessent's promise of long-term security implies a specific set of outcomes: the permanent degradation of Iran's nuclear program, the collapse or transformation of the Islamic Republic's ability to project power through proxies, the reopening and sustained security of the Strait of Hormuz, and a regional order that does not generate new sources of instability.

Each of those outcomes is uncertain. The 2003 Iraq War was also sold as a path to regional transformation. Twenty years later, Iraq remains unstable, Iran's regional influence expanded rather than contracted in the war's aftermath, and the total cost reached into the trillions [7].

Whether the Iran war ultimately proves to be a sound investment depends on outcomes that will take years to evaluate. What can be evaluated now is whether the costs are being honestly presented — and the evidence suggests they are not. The "bit of pain" framing minimizes costs that are already running well above historical comparisons, distributes burdens regressively, excludes second-order effects from cyber and proxy retaliation, and asserts a security return that no published analysis has quantified.
