Can we imagine a scenario where the dollar depreciates sharply?

During the COVID crisis, the dollar did not become stronger against the euro, as was the case during the subprime crisis, but it was shored up by capital outflows from emerging countries. We can then today envisage a significant depreciation of the dollar: If capital flows return to emerging countries, especially since the strong monetary creation and the very low interest rates in the United States may drive investors to emerging countries; If the likelihood of Joe Biden being elected president becomes high, his programme (higher wages, restrictions on oil and natural gas production, higher taxes on companies and large fortunes, capital gains) will discourage investment in the United States; Because the monetary expansion is even greater in the United States than in the euro zone.
