With its decision last week to pump an additional $1 trillion into the financial crisis, the government eliminated any doubt that [it has] no hesitation in pledging to spend previously almost unimaginable sums of money and running up federal budget deficits on a scale not seen since World War II. Indeed, analysts warn that the nation's next financial crisis could come from the staggering cost of battling the current one. Just last week, new initiatives added $600 billion to lower mortgage rates, $200 billion to stimulate consumer loans and nearly $300 billion to steady Citigroup, the banking conglomerate. That pushed the potential long-term cost of the government's varied economic rescue initiatives, including direct loans and loan guarantees, to an estimated total of $8.5 trillion -- half of the entire economic output of the U.S. this year. The spending already has had a dramatic effect on the federal budget deficit, which soared to a record $455 billion last year and began the 2009 fiscal year with an amazing $237-billion deficit for October alone. Analysts say next year's budget deficit could easily bust the $1-trillion barrier. I didn't think we'd see that for a long time," said Maya MacGuineas, president of the Committee for a Responsible Federal Budget. "There's a huge risk of another economic crisis, a debt crisis, once we get on the other side of this one." Once the financial crisis eases, higher interest rates and soaring inflation will be risks.
