AUD/NZD carry — frequently asked

What is the AUD/NZD interest rate differential?

The AUD/NZD interest rate differential is currently +2.10 pp — the Australian Dollar policy rate (4.35%) minus the New Zealand Dollar policy rate (2.25%). Australian Dollar carries the higher rate, so it tends to attract demand.

Does long AUD/NZD earn or pay swap (carry)?

Going long AUD/NZD 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 AUD/NZD differential matter more than today's?

Markets price the future, not the present. AUD/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 Australian Dollar and New Zealand Dollar central banks. Today's gap is largely already priced in.

Does the higher-yielding side of AUD/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.
