The Fed's quarterly Senior Loan Officer Opinion Survey, says U.S. banks have relaxed lending standards and more businesses looked for loans in the first quarter. Yet the demand for loans is sluggish. While auto loans increased, credit cards and other instalment loans were flat, and mortgage demand is decreasing. The sluggish demand for loans is holding back the growth in the profits of banks. This is also why the KBW Bank Index fell by 7.9% this year and bank stocks are not doing well. Lower revenue reduces the Net Interest Margin, a key measure for bank profitability- the difference between what is earned on assets and the cost of deposits and other laibilities. NIM went up to 3.77% in 2010 with the Fed's low interest policy. Since the first quarter of 2010 NIM is falling. NIM at 2.67% is flat at Bank of America, fell for Citigroup and Well Fargo, and only rose slightly at J.P. Morgan Chase.
