JPMorgan Chase CEO Jamie Dimon, asked about fierce competition across the financial industry, said he's starting to see parallels to the era before the 2008 financial crisis, when a rush to make loans ended disastrously. "Unfortunately, we did see this in '05, '06 and '07, almost the same thing the rising tide was lifting all boats, everyone was making a lot of money," Dimon told investors on Monday. While JPMorgan isn't willing to make riskier loans to boost net interest income, he said, "I see a couple people doing some dumb things. They're just doing dumb things to create NII." Dimon, who led the largest US bank through the 2008 financial crisis and scooped up two major competitors that collapsed, said he expects the credit cycle will eventually sour again though he is not sure when.
