In conjunction with his State of the Union address, President Obama reanimated the idea of taxing big banks’ debts to help stabilize the banking industry and prevent future financial crises. The administration argues that the new tax would discourage banks from taking on too much risk by making it “more costly for the biggest financial firms to finance their activities with excessive borrowing.”
The president’s bank-tax proposal is unlikely to gain traction in the new Congress, just as similar proposals from the administration in 2010 and, last year from the now retired Rep. David Camp (R., Mich.), did not move forward. But even if it became law, it wouldn’t put a sizable dent in bank debt. The reason is simple: The existing tax system strongly encourages debt finance and the proposed new tax will not fundamentally change this.
