What it is — Interest Rates in Forex
A central bank’s policy interest rate is the economy’s base price of money — and in forex it is the closest thing to gravity. Currencies flow toward higher expected yields: when the Fed holds at 4% while another bank cuts toward zero, holding dollars earns more, and USD firms across pairs over weeks and months.
Markets trade the expectation, set by rate futures and guidance, not just the announcement. That is why a perfectly “on-hold” decision can still move markets: the statement’s tone shifts what comes next.
Why it matters — Interest Rates in Forex
- Rate differentials drive trends — the backbone of the carry trade and year-long currency cycles.
- The calendar’s heaviest events are rate decisions and press conferences — top-tier volatility windows.
- They reprice everything: gold, indices, crypto risk appetite — all read the same rate story.
Carry in one worked example
Interest-rate gaps pay traders daily. Suppose Australia’s rate is 4.10% and Japan’s is 0.25% — a 3.85-point gap. Hold a long AUD/JPY standard lot (100,000 AUD) and the gap accrues roughly 3,850 AUD a year — about $7 a day at 0.70 AUDUSD, credited (or, short the pair, charged) at rollover, usually around 5 p.m. New York, often tripled on Wednesdays for the weekend. That is swap, the daily echo of the rate gap. Carry sounds like free money until the exchange rate moves: one bad AUD/JPY session can erase months of $7. Carry strategies survive on position size that respects the pair’s normal swings — the same formula, applied to a trade whose profit target is measured in points of interest, not pips.
Why one sentence from a central bank reprices everything
The policy rate is the gravity of finance: it sets the yield currencies pay to hold, discounts every bond, and anchors what equities are worth. When a bank shifts its path — one meeting’s guidance moving from “higher for longer” to two cuts next year — every yield-sensitive price re-prices against the new path at once: currency pairs adjust, gold (which pays nothing) re-competes with bonds, equities re-discount. This is why the verified 2026 rate-decision schedules sit on the calendar and why their dates are the busiest trading days of the year. You do not need to predict central banks to trade well around them — you need to know when they speak, size for both directions of surprise, and let the clock, not hope, decide your exposure.
Frequently asked questions — Interest Rates in Forex
Where is the schedule for 2026 decisions?
Our Economic Calendar lists rate-decision dates for the Fed, ECB, Bank of England, BoJ, RBA and SNB with projection flags, plus the live weekly feed.
How do interest rates affect forex pairs?
Through expectations and carry. A currency whose central bank is expected to raise (or hold high) tends to strengthen as money flows to the better yield; the realized daily version of that is swap, credited or charged at rollover each night.
What is the carry trade, in one sentence?
Borrowing in a low-rate currency to buy a higher-rate one and pocket the rate gap — profitable until the exchange rate moves against you by more than the gap pays, which is why sizing decides whether carry is an income or an anecdote.
Why does one bank matter more than others?
The Fed first — the dollar is on one side of ~88% of forex volume. Then ECB, BoE, BoJ, SNB, RBA, RBA-neighbors: banks whose policy diverges most from the Fed create the cleanest trends.
