Over the last few years, I’ve had some harsh words for bankers, banks, and the culture of the industry. In truth, I could have said worse, and it would have been justified.

That’s why the story of this bank—the Hancock Bank of Mississippi—deserves to be told, watched, and learned from. This is a case where banks play the role they are ideally meant to play, that is, they invest in the stabilization and growth of the community they’re part of, and wind up profiting in the long run from those investments.

It’s the way they did this that’s particularly remarkable—by literally laundering debris-covered dollar bills and handing them out to people in the days immediately following the Hurricane Katrina. How and why they did this is best left to the film clip; suffice it to say that Hancock gave out around $50 million in cash, with handwritten IOUs for contracts, and lost (only) about $200,000 of that when all was said and done. But in the 3 months following the storm, Hancock grew by $1.4 billion. It’s not hard to imagine that the kind of genuine investment they made in their community—both customers and not—earned so much loyalty.

Banks and their leadership have a long way to go to get out of the hole they’ve dug for themselves in the minds of most people. While disasters provide a great opportunity to show caring, I don’t think that banks need to wait for another hurricane to do something –there are many ways to show care and commitment to the community, and it’s in everyone’s interest that they start soon.
