Financial Compellence in the Iran Campaign
The Problem: Pressure Without Decision
After more than a month of sustained combat operations, Iranian military capability has been degraded, but no strategic decision has been forced. The current ceasefire is not a pause in the conflict—it is a window to apply pressure more effectively and force a decision. The United States is applying pressure. Iran is managing time to gain advantage.
The blockade has imposed real friction. Reuters reported that only five ships passed through the Strait of Hormuz in one recent 24-hour period, a dramatic drop from normal traffic. Yet the system is not airtight. Shadow fleet operations, ship-to-ship transfers, and residual exports still generate revenue, as Reuters has reported in describing U.S. interdictions of Iranian oil tankers in Asian waters and ongoing maritime sanctions evasion.
As long as cash continues to flow, the Islamic Revolutionary Guard Corps (IRGC) retains the ability to sustain internal control, fund proxies, and reconstitute military capability.
As Thomas Schelling argued, pressure imposes cost; compellence forces decision. Pressure can be endured. Compellence works by making delay more dangerous than compliance. Pain alone is insufficient. The adversary must believe that waiting will worsen its position.
Objective: ‘Hard Outcome 3’ Without Major Kinetic Operations
The objective should be a “Hard Outcome 3”—one of the defined outcomes in my earlier RealClearDefense analysis—representing a negotiated settlement that imposes durable, verifiable constraints without occupation or regime change.
This includes a permanent end to Iran’s nuclear weapons program, strict limits on enrichment, removal or verified disposition of highly enriched uranium (HEU), intrusive inspections, and verifiable constraints on missile, drone, and proxy capabilities.
These conditions represent the minimum terms the United States and Israel can accept without returning to major kinetic operations—and the outer boundary of what the IRGC leadership is likely to accept under sustained pressure.
Anything less risks a temporary pause rather than a durable outcome. The ceasefire allows the United States to increase pressure at lower risk while forcing Iran to absorb rising costs the longer it delays. It must be used to force decision—not enable recovery.
Center of Gravity: IRGC Usable Cash Flow
The decisive vulnerability in this campaign is financial. As Larry Kudlow recently captured, “no oil, no money.” I would extend that logic: no oil, no money—and no money, no IRGC network of soldiers, Basij forces, proxies, missiles, drones, or terrorist infrastructure.
In my Small Wars Journal article “Iran in the Box”, I argued that the United States and Israel employed a coercive architecture of kinetic strikes across multiple target sets to compel the regime toward Outcome 2 or a “Hard Outcome 3.” In subsequent analysis, I identified the regime’s reliance on oil export revenue—particularly through nodes such as Kharg Island—as a critical vulnerability in sustaining resistance.
Iran’s oil export system—spanning loading infrastructure, offshore storage, maritime transport, and financial intermediaries—remains the mechanism that sustains the entire enterprise. A UK Parliament research briefing notes that oil revenue has typically accounted for about a third of Iran’s budget and that roughly 90 percent of Iranian petroleum exports go to China. War on the Rocks has reported Iran’s planned 200 percent increase in its military budget, while the Foundation for Defense of Democracies has estimated billions annually flowing to proxy and client networks.
That cash funds internal security, proxy networks, procurement, and state operations. The implication is clear: the IRGC can absorb military pain longer than it can absorb the loss of usable cash.
Financial Compellence: How to Force Decision
The next phase must be a coordinated campaign of financial compellence—one that targets the entire chain by which Iran converts oil into usable cash.
The objective is not simply to reduce revenue, but to systematically deny the regime access to liquidity faster than it can adapt—compressing its financial decision cycle and operating inside Iran’s Observe–Orient–Decide–Act (OODA) loop. This campaign operates across multiple reinforcing layers.
First, the physical movement of oil must be constrained. Maritime enforcement should distinguish legitimate transit from illicit Iranian flows. Shadow fleet operations must be exposed and disrupted. Insurance and reinsurance pressure can further restrict the ability of these vessels to operate by raising costs and limiting throughput.
Second, conversion of oil into cash must be disrupted. Pressure on buyers and refiners raises both commercial and political costs. Diplomatic and economic leverage on key purchasers—especially in Asia—offers one of the highest-impact levers available. Even partial restrictions, escrow mechanisms, or compliance pressure can materially reduce usable revenue.
Third, access to the financial system must be denied. Correspondent banking channels, third-country proceeds, and front companies serve as the connective tissue of Iranian financial flows. Restricting these pathways through sanctions enforcement and financial intelligence limits the regime’s ability to access and deploy funds.
Fourth, transaction costs must be raised across the system. Cyber disruption of logistics and payment networks, combined with public exposure of sanctions evasion mechanisms, increases risk to counterparties. The goal is not simply disruption, but deterrence—making every transaction involving Iranian oil more complex, slower, and more dangerous.
Fifth, pressure should be applied directly to regime insiders. IRGC-linked assets and accounts held in Gulf financial centers and other jurisdictions represent both financial resources and personal leverage. Freezing or seizing these assets introduces pressure at the decision-making level, not just the systemic level.
These tools are most effective when applied simultaneously, compressing Iran’s financial timeline across all channels.
Make every usable dollar slower, riskier, and more expensive—until the IRGC faces a genuine liquidity crisis.
Distinction: Compellence vs Collapse
Some observers frame the objective as collapse or unconditional surrender. That is not the operational objective—at least not immediately.
The objective is compellence.
The historical record provides little support for regime change through air and economic pressure alone. Scholarly analyses of strategic bombing and coercion consistently find that air campaigns, even when sustained, rarely produce regime change without additional decisive factors such as ground forces, internal uprisings, or regime collapse dynamics. Cases often cited—Japan 1945, Serbia 1999, and Libya 2011—each involved factors beyond airpower alone, including invasion threats, domestic pressures, or rebel ground forces. If regime change were the objective, it would likely require the credible prospect of ground intervention. However, the purpose of pursuing a “Hard Outcome 3” is precisely to avoid that requirement—achieving durable constraints that make regime change unnecessary, at least in the near term.
A collapsing state introduces instability without guaranteeing compliance. A more realistic approach is to force the regime into accepting constraints that degrade its coercive capacity. Over time, a financially constrained and hollowed IRGC-dominated system may become more vulnerable to internal pressure from the Iranian population itself.
Off-Ramp: Forcing Decision, Not Endless Pressure
For compellence to succeed, pressure must be paired with a credible off-ramp.
Sanctions relief should be explicitly tied to verifiable conditions: nuclear restrictions, HEU removal, intrusive inspections, missile and drone limits, and reductions in proxy activity.
Verification must be continuous and enforceable, with relief phased against compliance rather than granted upfront.
As Schelling emphasized, compellence requires both threat and assurance. Effective compellence communicates both the cost of resistance and the terms of its end.
Conclusion: Use the Ceasefire to Force Decision
The ceasefire is not a pause—it is the decisive phase. The ceasefire must not become a recovery period. The blockade must not become a holding pattern.
The United States has generated leverage. It must now convert that leverage into decision by compressing Iran’s financial timeline.
The objective is not pressure—it is compellence: forcing a decision on acceptable terms before time restores Iranian leverage.
