Does the Bank of England need to prepare in advance? An analyst who previously worked at the central bank has proposed a bold hypothesis: what would be the consequences if the United States officially confirmed the existence of extraterrestrial life?

It sounds like science fiction, but her logic actually points to real financial risks—such a super black swan event could trigger panic in global markets, leading to bank system collapses, deposit runs, and asset price crashes. Traditional central bank stability mechanisms might be rendered useless in the face of an extreme confidence crisis.

This actually reflects a deeper issue: how fragile is the financial system? How much damage can an extreme confidence shock cause? From flash crashes in the crypto market to risk models in traditional banking, it seems to tell us that market psychology can determine the outcome more than any fundamental data. Central banks might really need to consider how to preserve market confidence in the face of unforeseen crises.
