The Federal Reserve has admitted that regulators lack the tools to monitor risks associated with traders such as Bill Hwang and his Archegos Capital, which collapsed earlier this year leaving banks exposed to losses of more than $10bn.

In its semi-annual report on financial stability, the US central bank warned that existing measures of hedge fund leverage “may not be capturing important risks”, pointing to the Archegos failure as an example of hidden vulnerabilities in the global financial system.

Hwang’s high-wire act was hard to monitor because family offices face limited disclosure requirements and because he used derivatives known as equity total return swaps.

Compounding the frustrations of US regulators is that the biggest losses in the Archegos affair were suffered by banking desks directly supervised by officials in other countries, like Nomura of Japan and Credit Suisse in Switzerland.

Gary Gensler, new chair of the Securities and Exchange Commission, told the House financial services committee on Thursday that he had directed his staff to consider new disclosure requirements for the total return swaps employed by Archegos.
