INSIGHT

Energy Shock Can Trigger Sustained Stagflation

Aahan Menon warns an energy-driven inflation shock could sustain and bleed into other sectors, making equities and bonds poorly suited to perform.
He highlights oil spikes as a recession catalyst that first raise CPI then cause demand destruction over time.

ADVICE

Estimate Expected Returns With Simple Benchmarks

Use simple, transparent expected return frameworks across asset classes: forward earnings yield for equities, yield curve for bonds, term structure for commodities, and interest differentials for FX.
Prometheus found commodities (energy) and FX offered the most attractive expected returns before the Iran shock, so adapt allocations accordingly.

INSIGHT

Commodities Gain Value As Prices Surge

Commodities become most valuable when spot prices rally because backwardation and supply shocks raise carry and expected returns.
Menon notes commodities show long flat medians with episodic, highly skewed positive returns during crises.
