Credit card issuers say they need more time to respond to the substantial data request made by the Consumer Financial Protection Bureau in its proposal to slash late fees.

Goldman Sachs said that investigations and inquiries into its credit-card business has expanded beyond the Consumer Financial Protection Bureau to include other government agencies.

If the industry's largest players reported more payment information to the credit bureaus, many consumers would qualify for better offers from competitors, the Consumer Financial Protection Bureau said. It's the latest example of the bureau's increased scrutiny of credit card companies.

About 3% of borrowers in their 20s and 30s became seriously delinquent on their credit card payments last quarter, significantly faster than older consumers. The picture was similar in auto lending, according to research by the Federal Reserve Bank of New York.

The San Francisco bank entered into a multiyear partnership with Choice Hotels, which operates brands such as Radisson, Comfort and Econo Lodge. The company had previously partnered on its credit cards with Barclays.

A core issue in the upcoming fight over late fees involves what data is being collected on card issuers' costs and losses associated with late payments.

A plan released Wednesday by the Consumer Financial Protection Bureau was more aggressive than anticipated, leading to share price declines at Synchrony Financial, Capital One and Bread Financial. "This skews toward the worst-case scenario," one analyst wrote.
