What consequences if capital flows no longer headed from the euro zone to the United States?

Today, sizeable capital flows head from the euro zone to the United States. This results in particular from the fact that Germany and the Netherlands lend their savings surpluses no longer to the other euro-zone countries, but to the rest of the world outside the euro zone, which is an appalling situation. What would happen if, thanks to the European recovery plan, the euro zone ended up using its savings and these capital flows from the euro zone to the United States disappeared? The euro would appreciate against the dollar, which , in the short term, could be negative for growth in the euro zone and positive in the United States; Interest rates would fall even further in the euro zone and would rise in the United States; Investment and potential growth would be boosted in the euro zone and curbed in the United States, which would no longer be able to finance investments with the euro zone’s savings.
