One of the major flaws that led to the banking crisis was that loan-to-deposit ratios across the banking sector were out of kilter. Banks were lending more than they had on deposit and were therefore entirely dependent on the wholesale market. The wholesale market dried up, which led to a huge calling in of loans. That was at the heart of the financial crisis.
The banks may be saying that they are more comfortable with their loan-to-deposit ratios, but if one looks at the figures, even HSBC’s loan-to-deposit ratio—for its UK business, rather than its international business—is about 100%. Historically, banks have been more comfortable in the 70% to 80% range. We therefore do need more savings in the economy and those come from the better-off saving some of the income that they earn.
