How Interest Rates Affect Forex

Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. The majority of retail investor accounts lose money when trading CFDs. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money. This page is general information, not financial advice.

Interest rates set by central banks are among the strongest drivers of currency prices. A currency tends to strengthen when its central bank raises rates or signals a rise, because higher rates attract capital; the Bank of England base rate and its gap with other central banks’ rates shape GBP pairs for a UK trader.

The central bank policy rates below are a snapshot as at 12 July 2026. Policy rates change at scheduled meetings, so treat each figure as dated and confirm the current rate at the relevant central bank before trading a differential.

Rates as published by each central bank, checked 12 July 2026 (sources: bankofengland.co.uk, federalreserve.gov, ecb.europa.eu, boj.or.jp). Because policy rates move at scheduled meetings, recheck the current figure at the relevant bank before trading a differential; this page carries the last checked date so a stale rate is easy to spot.

How do central banks and rate differentials move forex?

The Bank of England sets the UK base rate across eight Monetary Policy Committee meetings a year, and its decisions move GBP pairs sharply. Other major banks matter too: the US Federal Reserve, the European Central Bank and the Bank of Japan. What drives a pair is the differential, the gap between the two currencies’ rates, so GBP/USD reacts to both the BoE and the Fed. The way those majors and crosses are quoted is set out in the forex currency pairs guide. The current policy rates and meeting cadence for these banks are summarised in the dated table at the top of this page.

A GBP carry-trade example

A carry trade borrows a low-rate currency to hold a higher-rate one, earning the rate differential while the position is open. Buying GBP/JPY when UK rates sit well above Japanese rates earns positive carry on the position, paid as a small daily credit. With the Bank Rate at 3.75% and the Bank of Japan’s policy rate near 1% as at 12 July 2026, both stamped in the table above and worth rechecking at source, the roughly 2.75% annual differential on a £30,000 GBP/JPY position works out to about £2.25 a day in positive carry before any price movement in the pair. In practice the credit you receive is the broker’s swap rate, which builds a markup into the raw central-bank differential, so the figure actually paid is lower than the headline rates imply. The catch is that any leverage stays within the FCA’s retail caps, and a sharp move in the pair can wipe out months of carry in a day, so the strategy is far from risk-free.

Why it matters for a UK trader

Rate decisions and the language around them create the largest scheduled moves in GBP pairs. Anticipating a shift in the differential, rather than reacting after the announcement, is where the edge sits, and it is hard to do reliably. Knowing the BoE meeting calendar lets a trader manage exposure around the highest-volatility events. Rate expectations also move equity indices, so the same central-bank decisions feed through to index CFD pricing. Checking a broker’s rate-decision execution record against FCA-regulated broker reviews matters most around those events.

Common mistakes

Trading a rate decision without sizing for the volatility around it invites a fast loss. Reading the headline rate while ignoring the forward guidance misses what often moves the market more. Chasing carry without respecting the currency risk treats a leveraged position as a savings account. Trading a rate decision on a variable-spread account risks the widest costs exactly when volatility peaks, which is why some UK traders prefer fixed spread brokers around scheduled announcements.
