Second-Order Effects
The follow-on consequences of a shock — the part the market underprices because it requires reasoning past the headline.
Definition
First-order effects are the direct, mechanical response to a shock: a rate cut lowers borrowing costs, a sanctions package blocks specific flows. Second-order effects are what those changes induce next: refinancing waves, substitution into sanctioned commodities, FX realignment, credit revaluation.
Markets price first-order effects within minutes. Second-order effects often take days to weeks, which is where dispersion — and edge — lives.
