Fragile Banks Won’t Make the US or Europe Stronger

Less than 15 months after the world’s most recent banking crisis, regulators in the US and Europe are already poised to roll back reforms aimed at reducing the risk of further financial disasters. It’s a serious mistake.

At issue is where banks get their money. Most is borrowed from depositors and other creditors. If it’s not paid back on time, broader distress can ensue. The rest, known as equity or capital, comes from shareholders who stand ready to absorb losses. The more of the latter banks have, the better they’re able to inspire confidence and keep lending even in the worst of times.

The problem is that executives prefer to employ as little equity and as much debt as possible, because this maximizes government subsidies and boosts measures of profitability in good times.

After the 2008 subprime-mortgage crisis, regulators everywhere recognized that capital had been woefully lacking. Working through the Basel Committee on Banking Supervision, they agreed to impose new standards known as Basel III. Equity levels rose significantly, peaking at about 7% of assets among the largest American banks — though this was still less than half what research and experience suggest would be needed to weather a severe crisis. Europe was a laggard, barely exceeding 5% of assets (according to the most comparable measure).
