With analysts speculating that checking fees may soar, consumers face big decisions ahead. This month's Financial Security Index, released by Bankrate Inc., shows that nearly two-thirds of Americans say they would bolt over increased bank fees.

Among the findings:

•At 75 percent, adults making $75,000 or more per year, were most likely to consider moving their accounts;

•Nearly three out of four people, or 71 percent, under the age of 30 would choose a new financial institution if prices rose;

•In addition to concern over increased fees, Americans feel less secure with their overall finances for the second consecutive month;

•Savings continue to be the Achilles' heel of financial security.

"In these economic times, Americans are particularly sensitive to higher bank fees, with 64 percent saying they would consider switching to a different financial institution if their checking account fees increased," says Greg McBride, CFA, senior financial analyst for Bankrate.com. "Every dollar counts and consumers that are willing to pursue the best returns on their money are a step closer to achieving financial security."

Bankrate's Financial Security Index results are based on telephone interviews with a nationally representative sample of 1,006 adults living in continental US. The interviews were conducted from March 3 to March 6, 2011, by Princeton Survey Research Associates International. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error for the complete set of weighted data is + or - 3.7 percentage points.
