Carry and swap: does anyone hold positions for the interest?

Policy rates among the major central banks now range from 0% at the Swiss National Bank to 4.35% at the Reserve Bank of Australia (as of mid-September 2026), so the swap on some pairs is large enough to matter.

Questions for anyone who pays attention to it:

• Do you choose trades or holding periods partly because of swap?
• How close is your broker's swap to the actual rate difference? Brokers add a markup, and on some pairs both long and short swaps are negative.
• Has a sudden move in the exchange rate ever wiped out months of carry for you?

The carry trade guide explains why these trades can unwind quickly. Please share experiences rather than suggestions to buy particular pairs.
