The White House declined to comment. Officials had previously said their reforms would be announced in the coming days.
The measures, which are still being defined, are not likely to consider far-reaching changes to existing law. The White House is skeptical that such measures can pass in a highly divided Congress.
Instead, they would require implementation by the Federal Reserve, the Federal Deposit Insurance Corporation (FDIC), and the Office of the Comptroller of the Currency.
Other measures could include increasing bank capital requirements, tightening solvency tests for those banks and tightening plans for how they could be safely wound up, analysts said.
