Aren’t there reasons though?

Example: China holds the most foreign reserves. They are a natural world bank whether you want to call them that or not.

The US has oil and trade dominance, the USD is tied to petrodollar, aircraft sales, weapons, etc. and SWIFT - so that makes the US a kind of world bank in practical terms.

But what does Germany bring to the table? Energy? It seems to me that Russia, Iran, or even Mexico would be next in line considering the reality of trade and international finance. Why Germany?
