U.S. banks have been cooling off on their crypto interest since this year’s twin eruptions of Terra/LUNA and FTX, said Michael Hsu, the acting chief of the Office of the Comptroller of the Currency (OCC).

“Overall, I can say – and this is going to be obvious – is that there was more interest before Terra/LUNA and FTX than since Terra/LUNA and FTX,” said Hsu, whose banking agency released its Semiannual Risk Perspective report Thursday, in which cryptocurrency risks were given heightened prominence.

The report included a new section on digital assets as a “special topic in emerging risk,” and it pummeled the industry, saying its risk management practices “lack maturity.”
