The order of operations
When the FOMC hikes or cuts, the move flows outward from the short end of the Treasury curve. Two-year yields adjust within minutes — sometimes seconds — because they're the most direct expression of the policy path. Long-end yields move next, but only partially: the 10-year reflects both policy and growth expectations, so a hawkish hike that also signals slower growth can leave the 10-year roughly flat while the 2-year jumps. That's how a yield-curve inversion forms.
Stocks: discount rates and the earnings channel
Stocks feel a rate change through two channels operating at different speeds. The discount-rate channel is mechanical: higher rates reduce the present value of future cash flows, so growth stocks — which derive most of their value from earnings 5+ years out — fall hardest. The earnings channel is slower: higher rates eventually cool consumer spending, tighten corporate balance sheets, and compress margins. That hits cyclicals, banks (loan demand), and credit-sensitive sectors months after the hike.
- →Mechanical (days): Discount-rate repricing hits long-duration growth names — software, biotech, anything pre-profit — before cyclicals.
- →Behavioural (weeks): Rates affect risk appetite. Sustained tightening shifts flows from equities into money-market funds yielding 5%.
- →Fundamental (quarters): Margin compression and demand softness show up in earnings season — months after the policy shift.
Currencies: the rate differential trade
Forex prices the gap between two countries' policy paths. If the Fed hikes and the ECB holds, dollar buying intensifies because the carry on USD-denominated holdings improves relative to EUR. This is why EUR/USD and the DXY (dollar index) often move at the moment of the rate decision, even before the press conference. The exception is when the hike is fully priced — then the surprise is in the dot plot or Powell's language, not the headline number.
Commodities and emerging markets: the second-order squeeze
A stronger dollar makes dollar-denominated commodities (oil, copper, gold) more expensive in every other currency, suppressing demand and prices. Emerging-market borrowers who issued debt in dollars now face higher servicing costs in local-currency terms, which weakens EM equities and EM currencies in a feedback loop. This is why a Fed hiking cycle is often described as 'sucking liquidity out of the world' — the mechanism is the dollar, not the funds rate directly.
Crypto: the riskiest piece of the stack
Crypto historically behaves like a leveraged version of growth stocks: same direction, larger magnitude, with a slight lag. When rates rise, bitcoin and the broader crypto market typically follow tech-heavy indices down — sometimes within hours, sometimes over a few sessions. The lag exists because crypto trades 24/7, so the immediate post-FOMC move happens overnight when US equity markets are closed, and the next morning's equity move re-anchors crypto pricing.
When the playbook breaks
These linkages are tendencies, not laws. The unusual periods are the most informative: when the dollar weakens despite a hike (because the surprise is dovish forward guidance), when equities rally on a hike (because the market reads it as confidence in the economy), when crypto decouples from tech (regulatory news, ETF flows, or halving cycles). The skill isn't memorising the relationships — it's noticing when they break and asking what new factor is dominating.
