Transmission Mechanism
The chain of cause-and-effect by which a shock — a policy move, a kinetic event, a price surprise — propagates from its origin to asset prices.
Definition
A transmission mechanism is the sequence of intermediate variables that links an initial impulse (a Fed decision, an OPEC cut, a sanctions package) to the assets that ultimately reprice. Each step is a measurable channel: rates, credit, FX, commodities, real activity, earnings.
Professional investors map shocks through transmission chains rather than reacting to headlines because the second and third steps usually move first, and the final asset response is conditional on which channels are open.
Why it matters
Skipping the transmission chain is the single most common analytical error in macro investing. Without it, you are pricing the headline; with it, you are pricing the mechanism that will actually move the position.
Worked example
An OPEC supply cut → tighter physical balances → backwardation in the crude curve → wider refining margins → US CPI energy component → 2Y yields → USD basket → EM carry unwind. Each arrow is a tradeable leg.
