GBP/AUD carry — frequently asked
What is the GBP/AUD interest rate differential?
The GBP/AUD interest rate differential is currently -0.60 pp — the British Pound policy rate (3.75%) minus the Australian Dollar policy rate (4.35%). Australian Dollar carries the higher rate, so it tends to attract demand.
Does long GBP/AUD earn or pay swap (carry)?
Going short GBP/AUD earns positive carry, paid as the daily swap (rollover), because that side holds the higher-yielding currency (Australian Dollar). The opposite side pays the swap. Carry is simply the interest-rate differential turned into a daily cash flow.
Why does the expected GBP/AUD differential matter more than today's?
Markets price the future, not the present. GBP/AUD 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 Australian Dollar central banks. Today's gap is largely already priced in.
Does the higher-yielding side of GBP/AUD 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.
