Could you elaborate, please? It was my understanding (perhaps mistakenly) that because so many foreign entities, be they countries, corporations etc, depend on the USD and it functions both as a reserve and for international trading, the U.S. Federal Reserve can be more aggressive with "dovish" policy.

Or stated another way, if fewer people/institutions held USD abroad, the risk of inflation would be much greater.
