GBP/CHF carry — frequently asked

What is the GBP/CHF interest rate differential?

The GBP/CHF interest rate differential is currently +3.75 pp — the British Pound policy rate (3.75%) minus the Swiss Franc policy rate (0.00%). British Pound carries the higher rate, so it tends to attract demand.

Does long GBP/CHF earn or pay swap (carry)?

Going long GBP/CHF 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/CHF differential matter more than today's?

Markets price the future, not the present. GBP/CHF 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 Swiss Franc central banks. Today's gap is largely already priced in.

Does the higher-yielding side of GBP/CHF 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.
