Money flows to where it's treated best. When a country raises interest rates, its currency attracts foreign capital seeking higher returns. This is the most powerful long-term force in forex — more than any chart pattern.
Why Rate Decisions Matter
When the ECB raises rates and the Fed holds, EUR strengthens against USD. Investors can earn more holding euros than dollars, so they buy euros. This isn't speculation — it's capital flow driven by real yield differences.
CURIO's economic calendar flags every rate decision. These events can move a pair 100+ pips in minutes. Never hold through a rate decision unless you have a specific plan for it.
The Carry Trade
A carry trade borrows money in a low-interest currency (the "funding" currency) and invests it in a high-interest currency (the "target" currency). You profit from the interest rate difference, paid daily as swap.
Example: borrow JPY at ~0% interest, buy AUD bonds at ~4%. You earn ~4% per year just for holding the position — plus any capital gain if AUD/JPY rises.
The Risk: The Unwind
When risk-off sentiment hits, investors rush to repay the borrowed currency simultaneously. This causes the funding currency to spike and the target to crash — sometimes 5–10% in days. The 2008 unwind of JPY carry trades was one of the fastest forex moves in history.
How to Use This as a Trader
- ▸Know each pair's rate differential — it sets the long-term bias.
- ▸Rising-rate currencies tend to strengthen over weeks/months — trade them long on pullbacks.
- ▸Be cautious with carry trades during risk-off regimes (stock market panics, geopolitical crises).
- ▸Use the economic calendar to avoid being caught in rate-decision volatility.
