Brad Setser on the War in Iran and the Future of the US Dollar

Odd Lots · Tracy Alloway, Joe Weisenthal — Brad Setser · April 16, 2026 · Original

Most important take away

Despite widespread “de-dollarization” rhetoric, the dollar remains structurally strong because global investors (especially equity holders) are massively overweight US assets, and countries like China are still compelled to accumulate dollars via FX intervention. The current Iran oil shock is real but smaller than the 1970s, and the traditional petrodollar-recycling winners (Gulf states) are largely sidelined this time — winners are non-Gulf exporters like Kazakhstan, Norway, Angola, Nigeria, Colombia, and North American producers.

Summary

Context: Recorded April 15, 2026, shortly after a US/Israel-initiated war with Iran disrupted oil flows through the Strait of Hormuz. Oil is up roughly 50% from mid-February but has pulled back from peaks. Brad Setser (CFR) compares the moment to the 1970s oil shocks and walks through who benefits, where financial flows go, and whether the dollar’s dominance is truly under threat.

Actionable insights and investment-relevant points:

  • Oil market read: The futures curve is torn between two scenarios — a quick return to ~$60 if the US pulls back and Iran stabilizes, or a sustained $150+ if the choke point persists. Physical disruption (10–15% of global supply, 20–30% of traded oil) is enormous, but prices have not reacted proportionally. Traders should not assume efficient-market pricing fully reflects the physical shortfall; grade mismatches (North Atlantic sweet/light vs. Asian refineries configured for medium sour) and shipping logistics create real frictions.

  • Winners of this oil shock (where current account surpluses and currency strength are accruing):

    • Kazakhstan (KZT / dollar-tenge hit a low in early April — tenge has been strong)
    • Norway (especially if gas prices rise)
    • Nigeria, Angola, Colombia, other South American exporters
    • Brunei, smaller non-Gulf exporters
    • North American producers (US shale in Southwest Texas; Canadian Alberta production) — though this is largely a transfer from US consumers to US producers
    • Russia wins at the margin (Ukraine is limiting Russian flows)
  • Losers / sidelined: Gulf states (Kuwait, Iraq, UAE, Saudi Arabia) cannot physically get as much oil out. Saudi Arabia is now a net borrower — balance-of-payments break-even has risen from $60 to ~$95/bbl; Saudis borrowed ~$100B last year, making them the biggest EM borrower. The Saudi Public Investment Fund is NOT a source of petrodollars anymore — it’s a drain. UAE and Qatar remain cash-rich “Rockefeller-like” investors.

  • Stocks/companies mentioned:

    • Samsung — benefiting enormously from the AI memory-chip boom; Korean retail investors are still rotating out of Samsung into US stocks despite Samsung “printing money”
    • Saudi PIF — international portfolio is ~80% dollar-weighted (per Alex Etra’s work), more dollar-heavy than typical reserve portfolios
    • Taiwanese life insurers — have dramatically reduced hedge ratios, becoming a self-reinforcing bid for the dollar and weight on TWD
    • Japanese life insurers — similarly letting hedge ratios slip
    • Scandinavian pension funds — some reduced dollar bond holdings in response to Greenland rhetoric
  • Dollar/portfolio framing (key insight for asset allocators): A typical international large-cap equity portfolio is ~65–70% US; reserve portfolios are typically only ~57% dollars. So reserves are actually UNDERWEIGHT dollars vs. return-seeking equity investors. The dominant dollar flow into US assets today is equity-driven, not reserve-driven. De-dollarization narratives miss this — to truly de-dollarize, the world would have to stop funding the >$1T US current account deficit in dollars, and it isn’t.

  • Korea (KRW): National Pension Service is expanding its hedging program. If successful, this is a headwind for USD/KRW going above 1500 and supports KRW.

  • Europe: The oil/gas shock is manageable (~$40B hit to current account per $10 oil move), much smaller than 2022 Russian gas loss. The bigger structural issue for Europe is the China export shock and the need to produce its own missile interceptors.

  • Core investor takeaway: Despite geopolitical recklessness perceptions, the intense global overweight to dollar assets (safe reserves, private credit/CLOs, and US equities) remains sustainable so long as China keeps intervening to manage CNY and global investors keep chasing US large-cap outperformance. Watch for a breakdown in Chinese FX management or a full-blown US-Europe rupture as the real de-dollarization catalysts — not headlines.

Chapter Summaries

1970s oil shock analogy

Setser says the current shock is geographically similar (Middle East trigger) but much smaller in magnitude. In 1973 and 1979 oil doubled or tripled; today we are up ~50% from spot. The physical disruption is comparable or worse, but price response is smaller because the market expects the choke point to resolve.

Who wins this time

Unlike the 1970s, Gulf petrostates are sidelined because they can’t physically export. The winners are Kazakhstan, Norway, Nigeria, Angola, Colombia, Brunei, and North American producers. The hosts joke about needing a catchy acronym for non-Gulf non-sanctioned oil winners.

Legacy of the 1970s and birth of petrodollars

Oil was always priced in dollars (no deal was needed). Saudi dollar reserves were masked in Treasury data at Saudi request. Most petrodollars actually flowed into London-based eurodollar bank accounts and were recycled as loans to EM oil importers, seeding the 1980s Latin American debt crisis. By the late 1990s, cumulative Saudi surpluses had been spent down — petrodollar flows are not a continuous phenomenon.

Where Gulf money goes now

Evolution from reserve rebuilding (post-1998) to sovereign wealth funds. Norway runs a disciplined, predictable portfolio; UAE moved from conservative London-managed portfolios to more aggressive royal-directed bets; Russia aggressively de-dollarized pre- and post-Crimea. Reserve portfolios are actually LESS dollar-heavy than typical equity portfolios — a key correction to conventional wisdom.

China’s reserve management

China brought its disclosed reserve dollar share from 79% (2005) to 55%. But state banks hold 70% dollars, and netting offshore liabilities shows BOP flows remain nearly 100% dollar. China’s FX intervention ($100B/month before the Iran war) is the single biggest dollar buyer, far larger than anything petrodollar-related.

Korea anomaly

Simultaneous strong export/AI/memory-chip boom, weak currency, and massive retail outflows into US equities. NPS expanding hedging program. Korea is also a petroleum-intensive economy taking a negative hit from oil.

De-dollarization reality check

If the world were de-dollarizing, the dollar would be falling — it isn’t. World is longer dollars in 2025 than 2024. Modest trends: Scandinavian pension funds trimmed dollar bonds (Greenland rhetoric); Taiwanese lifers cut hedge ratios (self-reinforcing USD bid). Net effect is rotation from bonds to equities within the dollar bloc, not exit.

Sovereign wealth funds and domestic deployment

Gulf states (especially Saudi under MBS) are now deploying capital domestically — real estate, sports, entertainment, data centers. Saudi BOP break-even has risen to ~$95/bbl. Saudis borrowed $100B last year, flipping from petrodollar source to drain. UAE and Qatar remain structurally cash-rich.

Europe

The oil shock is modest (~$40B per $10 move). Bigger concerns: China export shock, missile interceptor supply constraints, US reliability.

The rogue-state question

Even if the world views the US as reckless, efficiency keeps the dollar dominant for transactions (e.g., Africa-Latin America trade). The real risk is the massive global overweight to US assets (reserves, private credit, equities) unwinding — sustainable for now, but the central question going forward.

Post-interview discussion

Hosts reflect on the “toll” framing — China’s political tolls, Iran’s potential strait toll, Trump’s consumer-market toll. Note that “choke point capitalism” is now the dominant geopolitical logic. Observe that middle powers (Mexico, Brazil, Kazakhstan) face the same China manufacturing shock as the US/Europe, complicating any “pivot to China” narrative.
