It's more that the english ain't parsing, for some at least.

The mining.com quote is classic weasel phrasing, seemingly meaningful yet disturbingly ambiguous:

  Due to rising gold prices, the move helped the bank to generate a capital gain of 13 billion euros ($15 billion), bringing it to a net profit of 8.1 billion euros for the 2025 financial year after a net loss of 7.7 billion euros in 2024.

So, the move helped the bank generate ...

Just as, say, one guy helped four others push a car back up on the road.

We've been given, accurately or not .. likely true, figures on how the bank did over a period, we've also been told the gold movements helped with that ... so they almost certainly kicked in at least $1.

Other costs? Deviations in the actual figures from the estimates we're using here? 100 is not a million miles away from 129.
