The global financial system is "much more stable" than before the 2008 crisis, but the threat that cyber risk poses to stability is not yet adequately understood, according to Wall Street veteran Blythe Masters.

Speaking at a plenary session on October 14 at the Sibos conference in Singapore, Masters, now the chief executive of a blockchain start-up, said that post-crisis regulation and the subsequent deleveraging had made the financial system safer, but the potential for cyber attacks remains a concern.
