DislikedCorrect me if I'm wrong, but the lot amounts are actually different for NZD/JPY and GBP/JPY.
That would be the reason for the huge difference.
100,000 Great British Pounds is much bigger than 100,000 New Zealand Dollars

Do the math. That difference does not even come close to accounting for the difference in swap rates paid on the two pairs, which is what prompted my question and this thread in the first place. From my original thread starter: "But here's what I discovered: when I held a GY position of $80K overnight, I was paid $47.28 the next day. Pretty cool. Then, thinking I had really found a cool thing and wanted to max it out, I held a NZD/JPY position also $80K overnight, but was only paid $8.20 the next day."
You might consider that you actually know less than you think you do before making such comments...
