Overview of Will Bessent’s “economic D-Day” break Iran?

This Financial Times Rachman Review episode examines the Trump administration’s renewed economic campaign against Iran, including Treasury Secretary Scott Bessent’s “economic D-Day” rhetoric, the likely limits of sanctions, and the broader consequences for oil markets, China, India, and U.S. grand strategy. Guest Emma Ashford argues that the policy is mostly a reprise of familiar “maximum pressure” tactics—likely to create pain, but unlikely to collapse the Iranian regime or produce decisive strategic results.

Key Takeaways

  • Bessent’s announcement is seen as overblown rhetoric, not a fundamentally new strategy.
  • The U.S. appears to be returning to “maximum pressure”: restricting Iran’s oil exports and hoping economic pain forces concessions.
  • Secondary sanctions on Chinese, Indian, Turkish, or Gulf entities could increase pressure, but it is unclear whether Washington is actually willing to impose them at scale.
  • Broad embargo-style sanctions are far more destructive than targeted financial sanctions—and historically much less successful.
  • The ongoing conflict has disrupted the Strait of Hormuz, but global oil prices have not surged as much as expected because markets have adapted.
  • The U.S. is portrayed as increasingly an “agent of chaos” in global markets through sanctions, export controls, tariffs, and war.

Sanctions on Iran: What’s Different This Time?

From Targeted Financial Pressure to Broad Economic Siege

Ashford distinguishes between two types of sanctions:

  • Earlier, more targeted sanctions:

    • Focused on specific banks, sectors, or IRGC-linked entities.
    • Aimed to pressure the regime without broadly punishing the population.
    • Sometimes effective in bringing parties to the table, as in the JCPOA-era negotiations.

  • Current approach:

    • Moves toward a fuller blockade of Iranian oil exports and commercial lifelines.
    • More likely to produce humanitarian harm and regime hardship than political collapse.
    • Historically, this kind of pressure has not reliably toppled regimes.

Why Sanctions Often Fail

  • Sanctions can force moderate policy concessions.
  • They usually do not work on core regime priorities.
  • The historical example Ashford cites is Iraq in the 1990s, where sanctions devastated civilians without removing Saddam Hussein.

China, India, and the Limits of U.S. Pressure

  • The U.S. still has leverage because of its control over the global dollar-based financial system.
  • Foreign banks often choose access to the dollar over Iranian trade.
  • But Washington’s willingness to push too far is constrained by:
    • China relations
    • Upcoming Trump-Xi diplomacy
    • Broader trade and geopolitical considerations
  • Ashford suggests Beijing has been careful but not openly confrontational about sanctions so far.
  • She doubts the U.S. will be willing to sacrifice wider China policy just to intensify pressure on Iran.

Oil Markets and the Strait of Hormuz

Why Oil Prices Haven’t Spiked More

Despite the danger posed by a disrupted Strait of Hormuz, oil markets have been cushioned by:

  • Strategic petroleum reserves
  • Floating storage and other temporary supply workarounds
  • Renewables growth
  • Electrification, especially in China
  • Alternative shipping routes and pipelines

Why the Shock May Not Last

Ashford warns that these buffers are not permanent:

  • Strategic reserves are being drawn down.
  • Temporary storage fixes are fading.
  • If transit through Hormuz remains constrained, prices could rise later.

Market Psychology and Political Risk

  • Traders initially believed White House signals about strikes and negotiations.
  • Over time, markets became more skeptical.
  • But complacency can be dangerous: if markets assume stability, they may reduce pressure on policymakers to end the conflict.

U.S. Grand Strategy and “Retrenchment”

Ashford argues the U.S. military is overstretched globally and should be more selective about its commitments.

Her Preferred Direction

  • Less dependence in Europe
  • A more moderate posture in Asia
  • More emphasis on China
  • Less automatic intervention in the Middle East

But the Trump Administration Is Inconsistent

She says the administration is pulled in conflicting directions by:

  • Anti-Iran hawks
  • Hardliners on Cuba and Venezuela
  • Tariff advocates
  • Civilizational / ideological factionalism

This makes U.S. policy look strategically incoherent.

Lessons for Russia-Ukraine

The conversation briefly compares Iran sanctions to Russia sanctions:

  • Russia is a much larger exporter and harder to isolate.
  • Sanctions on Russia mostly caused a re-routing of energy flows:
    • Europe stopped buying
    • China and India bought more
  • Sanctions have hurt Russia’s economy, but not enough to collapse the state.
  • The broader lesson: sanctions may weaken an adversary, but they rarely deliver the political outcome hoped for.

Bottom Line

Emma Ashford’s central argument is that the U.S. is repeating a familiar playbook with Iran—one that has been tried before and has not delivered decisive results. The “economic D-Day” framing signals toughness, but the real question is whether Washington is prepared to impose the costs, especially if that means clashing with China and destabilizing global markets even further.

Notable Insight

“We’re not talking about economic sanctions now. Now we’re talking about blockade… trying to completely cut off the Iranian economy, immiserate the people, collapse the government.”

This episode’s core warning is that economic warfare can create pain without producing victory—and may instead deepen global instability.
