With more inflationary pressure from higher oil and gasoline prices, there is less of a probability for the Federal Reserve to cut interest rates. That means higher interest rates, which means support for the US Dollar.
There is also a flight to "safety" where people buy US Treasuries in times of war and uncertainty.
In order to buy those Treasuries, one has to convert their currency into the US Dollar.
Thus, they buy Dollars.
Hope this helps educate people here on how the markets work.
You're welcome!
