Seriously answering your question. The net effect is the same. It matters little if a country has its currency as the currency of world circulation or if its currency is undervalued in the international market with low demand.
This is called the Cantillon Effect.
The US with its world currency has the natural advantage that no other country has, they are the last to suffer from monetary expansion.
The cantillon effect states that coin printing creates uneven inflation, benefiting the first people who come into possession of the newly created coin, as inflation destroys the value of coin over time, the sooner a person has access to that coin. , the more you will benefit. But over time, even that person benefited will also suffer from the late effects of this expansionist monetary nature, everything will depend on the progression of the circulation of this new currency created.
As all currencies today are fiat currency, there is no escape even for those at the top, but they will suffer less than ordinary people.
The inflationary effects that we are witnessing today in the US only confirm this statement. Since 2020, the US has printed trillions of dollars incurring unimaginable budget deficits, the world still felt the inflationary effects of this expansion in 2020, but now Americans are feeling the permanent inflationary effects of this monetary policy. As I said, there is no escape.
