How Rates Affect Currencies

Rate Hike → Currency Strengthens

  • Higher returns on deposits
  • Attracts foreign capital
  • Signals economic confidence

Rate Cut → Currency Weakens

  • Lower returns on deposits
  • Capital outflows
  • Stimulates borrowing/spending

Carry Trade

Traders exploit interest rate differences:

  • Borrow low-rate currency (e.g., JPY at 0.1%)
  • Invest in high-rate currency (e.g., AUD at 4.35%)
  • Profit: ~4.25% annually +/− exchange rate changes

Key Points

  • Rate decisions cause the biggest forex moves
  • Forward guidance (future rate expectations) matters as much as actual rates
  • Always check the economic calendar for rate decisions
