We're coming up on the fifth anniversary of Wall Street's meltdown. Banks have rarely had it this good. Earnings for financials, the second-biggest group in the S&P 500 after technology, soared 26 percent last quarter, more than any other industry, analyst estimates show. Housing is back. The stock market is at an all-time high. Investors are finally wiring in cash. The 25 financial firms in the S&P 500 that have so far reported second-quarter results posted earnings totaling $31.6 billion, exceeding estimates of $29.1 billion, Bloomberg data show. Finance is on track to surpass tech again as the most profitable industry in the country. First-half revenue at the six biggest U.S. banks climbed for the first time in four years. Goldman Sachs, Morgan Stanley, Citigroup, JPMorgan Chase, Bank of America, and Wells Fargo reported $43.3 billion in total first-half profit, the most since 2007. The S&P 500 Financials Index is up 26 percent this year, compared with the S&P 500's 18 percent gain. Flush banks cannot sell their bonds fast enough: Almost 60 percent of high-grade debt sales in the U.S. this month are from banks, the biggest ratio in two years, according to Bloomberg. Banks are somehow making gigatons of money despite onerous new regulations and capital requirements," writes HuffPo's Mark Gongloff. "Why, it's almost like they're not telling the truth when they warn, repeatedly, that these new rules will destroy their profits and the economy."
