(New York)

US financial shares might be in for a quick ride higher. Bank of America’s earnings came in 33% higher than last year, leading to a blowout for the sector. The news followed strong earnings from JP Morgan and Citi. BAML’s shares rose over 4% on the news with one analyst commenting that the numbers were “almost all you could have hoped for”. Rising interest rates were a key factor in the increasing earnings, as banks earned more from net interest margins.

FINSUM: These are great numbers, but they may only be temporary. Consumers have not yet started demanding higher interest payments on savings, but once they do (and we think they will), then banks’ net interest margins will start shrinking again.
