Net interest income increased 99% to $694 million on higher benchmark interest rates and customer credit balances.

Execution, clearing and distribution fees expenses increased 21% to $93 million driven by higher customer trading volume in options, the non-recurrence of a $3 million OCC rebate in the year-ago quarter, and a $1 million increase in market data fees, which are associated with market data revenue included in other fees and services.

General and administrative expenses increased $43 million to $85 million. The increase is largely attributable to reserves related to the previously-disclosed regulatory investigations into the use of unapproved electronic messaging and record-keeping requirements.
