Big banks have to raise capital by as much as 19% under proposed US rules

US regulators are proposing that big banks increase their capital levels to protect against future blowups following a regional banking crisis, one of the most sweeping overhauls of how lenders are regulated since the 2008 financial crisis.

Banks affected by the changes will see an aggregate 16% increase in their capital requirements. Regulators say the increase would primarily affect the largest banks and that most have enough capital already to comply. Capital is the buffer banks have to hold to absorb future losses.

Regulators also proposed changes in how these banks assess risks and widened the scope of the new rules to institutions with as few as $100 billion in assets, meaning roughly 30 banks would be subject to the same calculations.
