Nomura (NMR) announced that on March 26, 2021, "an event occurred that could subject one of its US subsidiaries to a significant loss arising from transactions with a US client."

Nomura said it is currently evaluating the extent of the possible loss and the impact it could have on its consolidated financial results.

It said, "The estimated amount of the claim against the client is approximately $2 billion based on market prices as of March 26. This estimate is subject to change depending on the unwinding of the transactions and fluctuations in market prices. Nomura will continue to take the appropriate steps to address this issue and make a further disclosure once the impact of the potential loss has been determined. As of the end of December 2020, Nomura maintained a consolidated Common Equity Tier 1 ratio of over 17 percent, which is substantially higher than the minimum regulatory requirement. Accordingly, there will be no issues related to the operations or financial soundness of Nomura Holdings or its US subsidiary."
