Another area in which higher rates are likely to affect consumers is credit card use. And last week, the Federal Reserve reported that the average interest rate on credit cards reached 14.26 percent in February, the highest since 2001. That is up from 12.03 percent when rates bottomed in the fourth quarter of 2008 — a jump that amounts to about $200 a year in additional interest payments for the typical American household.

With losses from credit card defaults rising and with capital to back credit cards harder to come by, issuers are likely to increase rates to 16 or 17 percent by the fall, according to Dennis Moroney, a research director at the TowerGroup, a financial research company.

“The banks don’t have a lot of pricing options,” Mr. Moroney said. “They’re targeting people who carry a balance from month to month.”

Similarly, many car loans have already become significantly more expensive, with rates at auto finance companies rising to 4.72 percent in February from 3.26 percent in December, according to the Federal Reserve.

Washington, too, is expecting to have to pay more to borrow the money it needs for programs. The Office of Management and Budget expects the rate on the benchmark 10-year United States Treasury note to remain close to 3.9 percent for the rest of the year, but then rise to 4.5 percent in 2011 and 5 percent in 2012.

The run-up in rates is quickening as investors steer more of their money away from bonds and as Washington unplugs the economic life support programs that kept rates low through the financial crisis. Mortgage rates and car loans are linked to the yield on long-term bonds.

Besides the inflation fears set off by the strengthening economy, Mr. Gross said he was also wary of Treasury bonds because he feared the burgeoning supply of new debt issued to finance the government’s huge budget deficits would overwhelm demand, driving interest rates higher.
