Central banks and forex

Why every FX trader watches the Fed, ECB, and BoJ.

TL;DR

Central banks set policy rates, manage their currency, and intervene when needed. Every major FX move traces back to a central-bank action or signal.

Major central banks

Each owns a currency and a mandate.

→Fed (US) — dual mandate: employment + 2% inflation
→ECB (EU) — primary mandate: 2% inflation
→BoE (UK) — 2% inflation, financial stability
→BoJ (Japan) — 2% inflation; historically ultra-loose
→SNB (Switzerland) — willing to intervene heavily
→RBA, BoC, RBNZ — 2% inflation targets

What moves currencies

High-impact events.

→Rate decisions — monthly or every 6 weeks
→Statements + press conferences
→Dot plots / projections — rates in 1–3 years
→Speeches between meetings
→Currency interventions — rare but huge

Reading policy stance

Hawkish = inclined to raise/hold longer. Bullish for currency. Dovish = inclined to cut/stay loose. Bearish for currency. Market trades the surprise vs prior expectations.

Worked example

ECB rate decision day

Consensus: hold at 4.00%. Lagarde signals no cuts until 2026.

Takeaway

The decision often matters less than the press conference. Pros trade the chair's tone.

Common mistakes

What to avoid

!Trading the rate decision — usually priced in
!Skipping the press conference — most of the action is there
!Ignoring intervention risk on JPY at 152+
!Confusing 'hawkish' with bullish for currency — sometimes hawkishness signals recession
