Wall Street watch out. Democratic presidential front-runner Hillary Clinton revealed proposals to keep financial institutions in check, including strengthening the Dodd-Frank financial reform laws and a tax on high frequency trading. ‘I think what we’re hearing is a real commitment to build on Dodd-Frank,’ said Harry Stein, director of fiscal policy at the Center for American Progress, based in Washington, D.C. ‘That’s a real central debate in this election because we’ve seen a real push from Republicans to weaken or repeal the law.’ Clinton wants to expand the Volcker Rule, which prevents banks from engaging in proprietary trading. She also is calling for regulators to have more power to split up some of the bigger banks that may increase systemic risk throughout the financial system.
