Bernanke warns strain from retiring baby boomers could 'seriously weaken' economy

WASHINGTON — Federal Reserve Chairman Ben Bernanke told Congress Thursday that the economy could be gravely hurt if the nation's fiscal house is not put in order and Social Security and Medicare aren't revamped.

"If early and meaningful action is not taken, the U.S. economy could be seriously weakened," Bernanke said in testimony to the Senate Budget Committee.

It marked the Fed chief's most extensive comments to date on the challenges facing the United States with the looming retirement of 78 million baby boomers, the oldest of whom will start retiring next year.

This huge wave of retirees will hit the U.S. budget as well as the economy, he said.

Absent policy changes by Congress and the White House, rising budget deficits are likely in the years ahead to increase the amount of federal debt outstanding to unprecedented levels, Bernanke said.

That could propel interest rates for consumers and businesses upward, which would be a worrisome development, he said.

"Thus a vicious cycle may develop in which large deficits lead to rapid growth in debt and interest payments, which in turn adds to subsequent deficits," he said.

The budget deficit last year totaled $248 billion, a four-year low. Bernanke noted the improvement but likened it to a "calm before the storm."

Spending on entitlement programs will begin to climb quickly during the next decade, he said. Federal spending for Social Security, Medicare and Medicaid will total about 15 percent of the gross domestic product by 2030, compared to roughly 8 1/2 percent of GDP in 2006, he said.

Forecasts call for the deficit to worsen for the 2007 budget year. The Congressional Budget Office is projecting $286 billion in red ink, while the White House is predicting an even bigger shortfall of $339 billion.

President Bush now wants to work with Congress to balance the budget by 2012. He'll be out of office by then.

Bernanke said that economic growth alone is unlikely to solve the nation's impending fiscal problems.

Fixing the problems, he said, will take persistence and a willingness by Congress and the White House to make difficult choices.

The Fed chief steered away from offering solutions.

"In the end, the fundamental decision that Congress, the administration and the American people must confront is how large a share of the nation's economic resources to devote to federal government programs, including transfer programs such as Social Security, Medicare and Medicaid," he said.

President Bush wants to work on the looming insolvency of the Social Security program. But his one-time plan to add private accounts to the system, once the centerpiece of his second-term agenda, withered in 2005 after meeting resistance from Democrats and Republicans alike. Bush has tapped Treasury Secretary Henry Paulson to gather ideas on how to restructure the program.

In his testimony, Bernanke did not discuss the future course of interest rates. Many economists believe the Fed will hold rates steady when it meets Jan. 30-31. The central bank has left rates alone since August, when it paused a two-year rate-raising campaign to fend off inflation.
