GBP/USD carry — frequently asked
What is the GBP/USD interest rate differential?
The GBP/USD interest rate differential is currently 0.00 pp — the British Pound policy rate (3.75%) minus the US Dollar policy rate (3.75%). The two rates are equal, so there is no yield advantage either way.
Does long GBP/USD earn or pay swap (carry)?
Whether long GBP/USD earns or pays swap depends on which currency has the higher policy rate. Hold the higher-yielding currency and you receive positive carry; hold the lower-yielding one and you pay it.
Why does the expected GBP/USD differential matter more than today's?
Markets price the future, not the present. GBP/USD can move on a widening or narrowing expected differential before any actual rate change, as new data and central-bank guidance shift the expected paths of the British Pound and US Dollar central banks. Today's gap is largely already priced in.
Does the higher-yielding side of GBP/USD always go up?
No. The rate differential is gravity, not a guarantee. It dominates in calm, risk-on conditions, but in a risk-off shock capital rushes to safe havens regardless of yield, and crowded carry positions can unwind violently.
