Arizona Tribune - US bank deregulation 'may have gone too far': Treasury Secretary

Yellen's prepared remarks, to a National Association for Business Economics conference, comes a day after US regulators charged with overseeing Silicon Valley Bank (SVB) acknowledged that they shared in the blame for its swift failure.

SVB's collapse in March following a bank run sparked a broader sell-off of banking stocks, while authorities including the Federal Reserve and Treasury embarked on a coordinated effort to prevent contagion.

While the failures of SVB and later Signature Bank did not trigger a financial meltdown, the "substantial interventions" required suggests more work needs to be done, according to Yellen's remarks.

Referring to banking turmoil and the pandemic, she said: "These events remind us of the urgent need to complete unfinished business."

Such measures include efforts "to finalize post-crisis reforms, consider whether deregulation may have gone too far, and repair the cracks in the regulatory perimeter that the recent shocks have revealed," she added.

"We must also address new areas of risk," she said, adding that any bank failure is a cause for serious concern.

For now, it is "important that we reexamine whether our current supervisory and regulatory regimes are adequate for the risks that banks face today. We must act to address these risks if necessary," Yellen added.

US authorities also need to address vulnerabilities in the nonbank sector, she said, noting that "shadow banks" have grown in the past few decades.

She flagged money market funds as an area where vulnerabilities of the system to runs and fire sales have been "clear-cut."

This week, US lawmakers accused regulators of failing to do enough to prevent SVB's collapse, despite knowing it was over-exposed to the risk of rising interest rates.
