A balance sheet is a snapshot on one day. This figure is exact as of 2025-12-31 and has moved since — banks report quarterly or half-yearly, so there is always a gap. The dollar figure uses the euro reference rate on that same date rather than today’s: restating a past balance sheet at a current rate would produce a different number about a different thing.
