From the full press release:
"In 2025 and at the start of 2026, while the volume of gold reserves remained unchanged, the Banque de France had to align a residual portion (5%) with technical guidelines, resulting in a significant realised currency gain. This exceptional foreign exchange income totalled EUR 11 billion for 2025."
-- the keyword here likely being "realized"
Is the logic that it's "unrealised" while the gold is stored in the US but becomes "realised" once it is stored in Paris? Why?
