Episode 553: The Secret of NIM

Deposits are the aqua vitae of banking, the water of life.

The very core of the traditional banking business model is gathering deposits at no to low-cost and lending the money back out at higher rates. Bankers used to reference the “3-6-3 Rule”: bring in deposits at 3%, make loans at 6%, and be out on the golf course by 3:00PM.

Money is the primary raw material in the business of banking. The difference between what financial institutions pay for that raw material is subtracted from what they earn from lending it out right at the very top of their income statements. That difference is net interest income, and it is the largest component of earnings for virtually every bank. As much as 95% or more for some.

Expressed as a ratio, the net interest margin or NIM is a key metric in measuring bank performance, and it’s been under considerable pressure lately. The traditional levers have been trying to lower deposit rates and raise loan rates, and hope you don’t lose too much volume. As the business has become more complex, so have the tools and strategies to reduce that pressure.

Today we get into some of the hidden levers that banks are using to add non-rate value, one focus is SBA lending. How new approaches and new technology is expanding the market for banks large and small, and also for fintechs; and how the secondary market is helping to improve liquidity and improve NIM.
