GBP/NZD carry — frequently asked
What is the GBP/NZD interest rate differential?
The GBP/NZD interest rate differential is currently +1.50 pp — the British Pound policy rate (3.75%) minus the New Zealand Dollar policy rate (2.25%). British Pound carries the higher rate, so it tends to attract demand.
Does long GBP/NZD earn or pay swap (carry)?
Going long GBP/NZD earns positive carry, paid as the daily swap (rollover), because that side holds the higher-yielding currency (British Pound). The opposite side pays the swap. Carry is simply the interest-rate differential turned into a daily cash flow.
Why does the expected GBP/NZD differential matter more than today's?
Markets price the future, not the present. GBP/NZD 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 New Zealand Dollar central banks. Today's gap is largely already priced in.
Does the higher-yielding side of GBP/NZD 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.
