By Patrick Rucker and Sarah N. Lynch WASHINGTON (Reuters) - The Republican leader of the House Financial Services Committee plans to scale back banking reforms, curb the consumer finance agency and ease regulations on financial institutions and companies looking to raise capital, according to a proposal seen by Reuters on Thursday. In a four-page memo on the legislation he intends to introduce, Texas Representative Jeb Hensarling made a slew of proposals, including one that Wall Street banks' "stress tests" be performed every two years instead of annually as is done now. The memo does not mention the Volcker rule, which limits bank's ability to make speculative investments in banks' own accounts.
