Markets talk about "the Fed" the way sailors talk about the weather — but the Fed is one of several central banks whose decisions move global prices, and some of the biggest trades of the past two decades were built not on any single bank's policy, but on the gaps between them. A working map of the majors is standard equipment for reading FX, bonds, and global equities.
Why the Fed still sets the tone
The dollar is the world's reserve, funding, and invoicing currency, so Federal Reserve policy is transmitted everywhere: dollar debt exists on every continent, commodities price in dollars, and global risk appetite breathes with U.S. financial conditions. That is why Fed rate expectations get an entire market apparatus of their own. But "the Fed matters most" is not "only the Fed matters" — and for currency pairs specifically, the other side of the pair is always another central bank's story.
The majors, in character
- European Central Bank (ECB). Sets policy for twenty economies sharing one currency but not one treasury — Germany and Italy get the same rate with very different debts. Its mandate is price stability first (unlike the Fed's dual employment-inflation mandate), and its structural burden is fragmentation risk: the spread between member states' bond yields is a political fault line no other major bank manages. ECB decisions and its president's press conference are the euro's biggest scheduled events.
- Bank of Japan (BOJ). For decades the world's laboratory of extreme easing — zero and negative rates, massive asset purchases, and yield curve control (pinning long-term yields directly, a policy covered conceptually in the yield curve guide). Because Japanese institutions hold enormous foreign bond portfolios funded with cheap yen, BOJ policy is a global variable: when Japanese yields rise, Japanese capital comes home, and bond markets everywhere feel the tide. The yen is also the classic funding currency — BOJ surprises detonate carry trades across the planet, as markets get periodically reminded.
- Bank of England, and the rest of the G10. The BOE runs a mid-sized open economy acutely sensitive to housing and trade. The Swiss National Bank manages a permanent safe-haven bid, historically via intervention. Canada, Australia, and New Zealand's banks lean against commodity cycles and housing booms — their currencies covered in the forex guide. Each publishes its own meeting calendar, and each meeting is that currency's local Fed day.
Divergence: where the trades live
The single most productive lens for global macro is policy divergence — two central banks moving in different directions or at different speeds. Capital flows toward the tightening bank's currency and away from the easing one's, which is the engine behind most large, durable FX trends: the dollar's great runs have coincided with the Fed tightening while Europe and Japan eased. Divergence also drives bond spreads (the gap between two countries' yields) and equity rotation between regions. The practical habit: for any cross-border position, know both banks' next meeting dates and current direction. A EUR/USD view is a Fed view and an ECB view, whether the trader admits it or not.
The shared playbook — and the shared problem
All majors work the same toolkit: a policy rate, balance-sheet operations (QE and its reverse), and forward guidance — moving markets with words about future policy, the cheapest tool of all. All face the same core problem: policy acts on the economy with long, variable lags, so every bank is steering by instruments that report the past. And all of them communicate through calibrated language that markets parse like scripture — a shifted adjective in a statement can reprice a currency. It is the same fedspeak game globally, played in several accents.
A watcher's checklist
Keep the meeting calendar for any currency you trade — decisions, then press conferences, where the surprises usually live. Read decisions against expectations, not in absolutes: a hike that was fully priced can sink a currency if the guidance disappoints, the same consensus mechanism as every data release. Watch inflation data in each region as the input each bank is reacting to. And respect intervention risk in currencies whose officials have drawn public lines. None of this predicts decisions — it ensures that when one lands, you know which world just changed: the rate, the guidance, or merely the adjectives.
