The problems facing Wall Street are many: from poor trading results, to the slow investment banking activity, to fee reductions required by financial reform, to flatter yield curves, and to weak demand for loans, the entire world seems to be conspiring to destroy banking revenue.

But earnings results at megabanks and regional banks alike are beginning to show a positive trend: loan growth.

Weak loan growth was perhaps the biggest impediment to sustainable growth on Wall Street. But now loans are beginning to come back for a huge number of regional and national banks -- Bank of America, which is in the process of shoring up its balance sheet, aside.

This is good news not just for banks, but for the economy as well. When the economy cratered in 2008 and early 2009, loans fell. Today, they seem to be making a comeback:

While an unhealthy chunk of these loans may consist of old housing debt that borrowers will ultimately be unable to pay back, the recent loan growth suggests that economic activity among consumers and businesses is beginning to return. That's good news for most companies and the Dow (INDEX: ^DJI), as positive economic news in employment and manufacturing has been a big driver of the Dow's gains this year. If loan growth persists, it's an even better sign for revenue banks and cyclical industries that are economically sensitive.
