NEW YORK, June 28 (Reuters) – One of the sleeper provisions in the 2,000-page financial regulatory reform bill may be one that is no more than six paragraphs long.

The brief section of the massive bill is aimed at stamping out some of the conflicts of interest that arise from Wall Street’s packaging and marketing of asset-backed securities — investment products backed by a pool of mortgages, loans or bonds.

The measure could give U.S. securities regulators the authority to ban a narrow class of so-called securitized products that enable Wall Street banks to take the opposite side of trade from a client, lawyers and other structured finance experts said.

“It may eliminate a certain class of deals,” said Jerry Marlatt, an attorney in New York with Morrison & Foerster.

Some on Capitol Hill have dubbed the provision the Goldman Sachs amendment because its legislative proponents introduced the measure after the U.S. Securities and Exchange Commission sued Goldman Sachs Group Inc <GS.N> over its sale of subprime mortgage-linked security called Abacus 2007.
