Distinguishing himself as Obama's point man on Wall Street reform, Paul Volcker called for aggressive structural changes in the financial sector in Sunday's New York Times. The former Fed chair argued for separating big banks from their risky speculative investment operations. He also called for improved regulation and capital requirements. These are all necessary steps to prevent another collapse, writes Volcker. "We need to face up to needed structural changes, and place them into law. To do less will simply mean ultimate failure—failure to accept responsibility for learning from the lessons of the past and anticipating the needs of the future." How's the column being received? Here's what business writers and econo-bloggers are saying:

  • Volker Has Thrown Down the Gauntlet, writes Prairie Weather: "Deep structural change is unavoidable. Can't you just hear the screams of agony from the opposition and from Wall Street?  Watch for the markets, Wall Street lobbyists, and profiteers in the Senate -- like the wives of the powerful during the revolution -- faint at the sight of the guillotine! ...The guillotine is under construction.  Prepare for battle over its use."
  • Doesn't Go Far Enough, insists Yves Smith at Naked Capitalism: "While Volcker does speak of the need for structural reform, which is absolutely necessary, his outline does not go anywhere near far enough to start defusing the bomb that financial services deregulation managed to create...The unintended message of Volcker’s op ed may be that even someone as tough-minded as he is may not recognize the magnitude of structural change needed to limit the extent of government guarantees to the financial sector and contain officially-backstopped risk-taking."
  • Pretty Good Overall, writes Stephen Glain at The National: "The point of Mr Volker’s initiative, however, is not so much to eradicate risk as to smash the oligarchy that dominates Wall Street more than a year after it required hundreds of billions of dollars in taxpayer funds to stay afloat... However imperfect, the Volcker rule would do much to restore a measure of restraint on Wall Street."
  • Is Volcker the New Geithner?  Henry Blodget at The Business Insider suspects Obama has sidelined Tim Geithner: "By choosing someone else to sell the plan, the Obama administration is sending the message that someone else (Volcker) is responsible for it.  This means the administration is [likely] benching Tim Geithner and taking a new harder line against Wall Street...but waiting a bit to carry out the formal execution, so as to avoid embarrassing the President for supporting Geithner for so long."
