Although people claim that Baba Vagna was a prophet, she did not say anything about the coming of the coronavirus. 
Since she said nothing about the coronavirus, it seems skeptical at best to think that she said anything about a financial crisis. She also shared prophecies that did not come true, such as Barack Obama serving as the last president, and war decimating Europe. 
The failure of her prophecies deems her as an unreliable mystic. Therefore, her claims about a financial crisis are null.
