OUR nation’s Congressional machinery was humming last week as legislators reconciled the differences between the labyrinthine financial reforms proposed by the Senate and the House and emerged early Friday morning with a voluminous new law in hand. They christened it the Dodd-Frank bill, after the heads of the Senate Banking and House Financial Services Committees who drove the process toward the finish line.

The bill is awash in so much minutiae that by late Friday its ultimate impact on the financial services industry was still unclear. Certainly, the bill, which the full Congress has yet to approve, is the most comprehensive in decades, touching hedge funds, private equity firms, derivatives and credit cards. But is it the “strong Wall Street reform bill,” that Christopher Dodd, the Connecticut Democrat, said it is?

For this law to be the groundbreaking remedy its architects claimed, it needed to do three things very well: protect consumers from abusive financial products, curb dangerous risk taking by institutions and cut big and interconnected financial entities down to size. So far, the report card is mixed.

On the final item, the bill fails completely. After President Obama signs it into law, the nation’s financial industry will still be dominated by a handful of institutions that are too large, too interconnected and too politically powerful to be allowed to go bankrupt if they make unwise decisions or make huge wrong-way bets.
