Large Wall Street banks would have more trading freedom under the Volcker rule as a result of changes US regulators are considering, according to people familiar with the matter, The Wall Street Journal reports.

The draft changes to the rule, which restricts bankers’ trading activities, are designed to lower the burden banks face to prove that short-term trades don’t violate the rule, the people said. Regulators are also seeking to alter the definition of permitted hedging and market-making activities, to limit the rule’s impact on non-US investment funds, and to cut compliance requirements for banks with trading desks under a certain size, the people said. The changes could be published as soon as late May.
