Hormuz Shipping Disruption As Near Term Shock Vector
- President Trump paused bombing Iranian power plants while citing productive talks and set a five-day deadline for Iran to reach a deal amid conflicting claims about negotiation channels.
- Historical episodes in 1973–1974 and 1978–1979 illustrate that military success can coincide with economic recession when oil-supply disruptions trigger large energy shocks.
- Iranian demands such as controlling the Strait of Hormuz and receiving reparations are far from terms the United States could accept.
- Iran can still impose a severe global economic shock by cheaply threatening shipping and potentially mining the Strait of Hormuz, shifting U.S. war aims toward reopening the strait.
- Reopening the Strait of Hormuz without removing the current Iranian regime would likely be an unstable outcome because the regime could rebuild and reclose the strait using low-cost methods.
- Possible next steps include covert support to internal opposition gaining control of parts of Iran and expanded strikes on economic targets such as pipelines to constrain Iran’s ability to export oil.
Propagation Channels Disinflation From Supply Disruption And Financial Structure
- The Great Depression included four distinct regional banking crises rather than a single monolithic banking crisis.
- Supply disruptions can produce disinflationary recessions because lost production reduces hiring and investment, lowering incomes and demand.
- The 1919–1920 U.S. recession was driven largely by widespread postwar industrial action tied to real wages lagging wartime inflation, including in the coal industry.
- The 1920–1921 disinflation reflected a positive agricultural supply shock and the end of industrial action, which policymakers would have found difficult to observe in real time.
- A depression-level U.S. contraction from 1717 to 1720 was driven by pirate predation that brought American coastal commerce and shipping close to a standstill.
- Export collapses after cash-crop shocks can drain external reserves and transmit disinflationary pressure through the economy.
Policy Response As Amplifier Or Mitigator With Asymmetric Downside
- Friedman and Schwartz argued that the Federal Reserve’s 1920 monetary tightening was a policy mistake given subsequent disinflation.
- The economic damage of 1970s oil shocks may have been driven more by policy errors such as price controls than by oil-price increases themselves, so a recession after an oil shock is not mechanically inevitable.
- Non-price rationing is a recurring response to energy shocks and can worsen outcomes compared to price adjustment.
- Across a historical sample of 132 recessions, increased state size over time did not shorten average recession depth or duration.
- Government policy can materially worsen downturns.
- The Great Depression was worsened by contractionary monetary and fiscal policy.
Long Run Stability Measurement And Exposure Structure
- The post-1945 moderation narrative is partly a statistical artifact from pre-1927 measurement issues and partly because 1914–1945 was an unusually volatile baseline.
- From 1926 to about 1972–1973, the UK’s reliance on coal made it less exposed to postwar oil shocks.
- The UK had no major banking crisis from 1826 to 2008.
- The longest recessions on both sides of the Atlantic are associated with major wars that significantly affected home soil, including a deep UK recession from 1943–1947.
- Over the long run, expansions have become longer and recessions less frequent.
- There is no robust trend break in recession/expansion behavior attributable to the Federal Reserve’s creation, FDR’s election, or the UK Beveridge Report; a possible U.S. break may have occurred around 1785.
Risk Narratives And Governance As Threat Amplifiers
- Elite concern is shifting toward fears that AI and robots will become the next civilizational threat narrative.
- Over the last century, the biggest consistent threat to humanity has been totalitarian regimes, and AI becomes especially dangerous when controlled by such regimes.
- Many alarmist predictions about climate change have already been proven wrong.
- Doomsday forecasts fail because they rely on linear thinking and ignore multi-factor interactions that drive outcomes.
- Paul Ehrlich advocated coercive population-control measures such as forcible sterilization and these ideas contributed to large-scale human-rights violations in Asia.

Unknowns
- What is the underlying dataset and methodology supporting the claim that expansions do not become more likely to end as they age, and how sensitive is it to how "shock" is defined?
- What specific evidence supports the assertion that recessions are fundamentally unforecastable, and does it mean unforecastable in timing, magnitude, or both?
- How well-supported are the proposed disinflationary channels from supply disruption and reserve drains in modern data, and what observable indicators would discriminate them from demand-led downturns?
- What is the empirical basis for the claim that government size does not reduce recession depth or duration, and what definitions of "state size" are used?
- What is the current verified operational state of the Strait of Hormuz (traffic levels, insurance rates, mine-countermeasure activity), and is there confirmation of attempted mining or credible mine threats?
