Factors affecting the choice of non-deposit funding sources.

When deposits aren’t enough, banks knock on the doors of the money and capital markets. But choosing the right funding source is like picking the right topping: it depends on price, taste, shelf life, and how spicy it can get.

🧮 Key factors include:

  1. Cost: Cheapest is tempting, but not always best.
  2. Risk: Will this pepperoni make the pizza soggy later?
  3. Maturity: Do I need it for a quick meal or a banquet?
  4. Size: Can I handle jumbo-sized ingredients?
  5. Regulation: Are there rules on how much cheese I can use?

❓What’s the cheapest short-term source? Usually, Fed Funds — borrowed overnight from other banks.

But what if the cheese is cheap today and moldy tomorrow? That brings us to…


⚠️ II. RISKS OF EACH FUNDING SOURCE — THE PRICE OF PIZZA INSURANCE

Sure, Fed Funds are affordable, but their interest rate is like a teenager’s mood — changes every day. Commercial paper and CDs are less moody but cost more.

Banks also worry about:

  • Credit Availability Risk: What if their usual vendor suddenly says, “No dough for you!”?
  • Volatility: Like anchovies on pizza — some days spicy, other days meh.

❓How do banks sleep at night? They diversify — a bit of this, a bit of that, and they avoid indigestion.


⏳ III. MATURITY AND TIMING — DO YOU NEED A SNACK OR A FEAST?

Banks match the maturity of funds with the reason they need them.

  • Need to cover daily expenses? Use Fed Funds.
  • Planning to buy a building? Look for longer-term CDs or commercial paper.

Just like you wouldn’t buy a gallon of sauce for a midnight snack, banks don’t take 5-year loans for 5-day needs.

❓Is every bank eligible for all options? Not really. That leads us to…


🏦 IV. SIZE AND REGULATORY LIMITS — CAN SMALL BANKS HANDLE THE BIG TOYS?

Small banks may not be welcome at the big boy table:

  • Negotiable CDs often come in \$1 million denominations.
  • Secondary markets prefer prime-rated banks.

Also, regulators act like strict kitchen managers:

  • Minimum CD maturity: 7 days.
  • Reserve requirements: Surprise! You need to save sauce before spending it.

📊 V. COST OF FUNDS — THE BIG CALCULATION PARTY

Overall cost of funds uses both the historical average cost and the pooled-funds approach.

Let’s go full nerd with two methods:


🧮 Method 1: Historical Average Cost Approach

This is the looking-in-the-rearview mirror method.

Steps:

  1. Weighted average interest expense = total interest paid / total funds raised
    $=$ $($24.75M$/$900M$)$ $=$ 2.75%
  2. Breakeven Cost Rate
    $=$ $($24.75M $+$ 11M$)$ $/$ 800M $=$ 4.47%
  3. WACC — Weighted Average Cost of Capital
    $=$ $4.47\% + \dfrac{12\%}{(1 – 0.2)} \times \dfrac{100}{800} = 6.35\%$

So, Orange Tree Bank must earn at least 6.35% on its assets just to break even after paying everyone — including shareholders who demand their slice of the pie.


🧮 Method 2: Pooled Funds Approach

This one’s forward-looking. The bank asks: “How much must I earn on every new dollar I raise?”

Example:

  • Total raised: \$270M
  • Investable: \$221M
  • Expenses: \$22.6M
  • Pooled Cost Rate = \$22.6M / \$270M = 8.37%
  • Hurdle Rate = \$22.6M / \$221M = 10.23%

So Orange Tree Bank needs to earn 10.23% on each new dollar to cover future costs. If it earns less, it’s like burning the pizza.


🍕 Final Slice of Logic

We began by saying banks need extra toppings $($nondeposit funds$)$ when deposit dough runs thin.

We learned how choosing the right topping depends on price, expiry, portion size, and kitchen rules. Then we added math sauce — historical and pooled cost of funds — to measure if it’s worth the investment.

🧠 So what next?

Well, if costs rise and customer deposits shrink, how do banks protect themselves?

👉 That’s where liquidity buffers and funding diversification come into play.

And as always, in banking — just like cooking — the secret is balancing taste $($returns$)$ with caution $($risk$)$.
