MacroVoices #524 Simon White: War + Inflation = More Inflation
Bloomberg strategist Simon White argues that the Iran conflict could trigger a 1970s-style secular inflation cycle, with oil price shocks potentially leading to broader food price inflation. Energy expert Rory Johnston warns that the Strait of Hormuz disruption, if prolonged, could cause $200+ oil and a global economic crisis.
Summary
This MacroVoices episode, recorded on March 19, 2026, features Bloomberg macro strategist Simon White and energy expert Rory Johnston discussing the ongoing Iran conflict and its potential inflationary consequences. White presents a compelling case that current events mirror the 1970s inflation cycle, comparing the Iran conflict to the Yom Kippur War of 1973. He argues that inflation is currently the most mispriced asset, with markets showing complacency about second-order effects. White notes that in the 1970s, food inflation actually had a bigger impact on CPI than energy, and expects similar dynamics today due to disruptions in fertilizer supply chains through the Strait of Hormuz. He predicts yield curve steepening and warns about private credit vulnerabilities. Johnston provides a sobering assessment of the energy situation, explaining that the 90-95% reduction in Strait of Hormuz traffic was unexpected by experts. He argues the Trump administration entered the conflict without adequate planning, expecting a quick resolution similar to previous operations. Johnston warns that even if the conflict ends immediately, it would take months to normalize supply chains, and prolonged conflict could push oil prices to $200+ per barrel, potentially causing economic devastation in developing nations. The episode also covers market technicals across asset classes and introduces a wheat-focused trade to hedge against coming food inflation.
Key Insights
- Simon White argues that inflation is currently the most mispriced asset in markets, with break-evens showing only temporary price spikes rather than sustained elevation
- White contends that current events parallel the 1970s inflation cycle, specifically comparing the Iran conflict to the Yom Kippur War as a catalyst for sustained inflationary pressures
- In the 1970s analysis, White demonstrates that food inflation ultimately had a larger weighted contribution to CPI than energy inflation, contrary to popular perception
- White predicts that disruptions to fertilizer supply chains through the Strait of Hormuz will trigger significant food price inflation within six months based on historical patterns
- Rory Johnston reveals that energy experts universally failed to predict the current Strait of Hormuz shutdown because they never expected a US president to engage Iran without a clear exit strategy
- Johnston argues that the Trump administration expected a quick resolution similar to previous conflicts but miscalculated Iranian political culture compared to Venezuela
- Johnston warns that even immediate conflict resolution would require 3+ months to normalize supply chains due to the 400 million barrel supply gap already created
- White identifies private credit as the weakest link in the current economic cycle, drawing parallels to the 'contained' subprime crisis of 2007
- Johnston calculates that sustained conflict would require 15-20 million barrels per day of demand destruction, equivalent to COVID lockdown levels but achieved purely through price mechanisms
- White argues that the new Fed chair Kevin Walsh is more likely to resemble dovish Arthur Burns than hawkish Paul Volcker in response to inflation pressures
- Johnston explains that current oil price differentials show Oman crude trading at $150+ while WTI remains below $120, indicating severe regional supply distortions
- White predicts yield curve steepening similar to the 1970s OPEC 1 shock, driven by rising break-evens and a dovish Fed response to supply-driven inflation
