Understanding the Texas Ratio

The retail banking system operates on a fundamental promise between the bank and the customer.  The customer opens an account and deposits money in it with the expectation that the bank will continue to stay in business and that the funds will be available for withdrawal when needed. But, history tells us that this isn’t always the case.

Throughout history, there is a long list of notable bank failures, the largest of which occurred in 2008 when Washington Mutual collapsed with $307 billion in assets.  When something like this happens, it causes panic and a tremendous amount of concern over what happens with account holder money.

To prevent this, analysts have developed a set of metrics that act as a sort of early warning system of potential bank failures.  One of the most important and widely used is called the Texas Ratio.  To understand how it works and why it matters, it is first important to review, at a high level, how a bank operates.

How a Bank Makes Money

At its most fundamental level, a bank’s business model is fairly simple.  Banks solicit low-cost deposits from customers in the form of checking and money market accounts, and use the money deposited to lend to other customers at an interest rate that is higher than what was paid to acquire them.

The difference between the interest paid on the checking and money market accounts and the interest earned on the loans is known as the “Net Interest Margin” and it is a major driver of a bank’s profitability.

To illustrate this point, assume that a real estate developer has a checking account with a local bank that has a balance of $100,000 and an interest rate of .2%.  At this rate, the developer would earn $200 in interest per year, assuming the balance stays the same.  To complete a renovation on a new project, the same bank also provided a loan to the developer for $100,000 at an interest rate of 5.50% and with a term of 1 year.  Assuming the balance stays the same throughout the year, the bank will earn $5,500 in interest on this loan.

The difference between the amount paid to acquire the deposits, .2% or $200, and the amount earned on the loan, 5.50% or $5,500, is 5.3% or $5,300 and represents the Net Interest Margin for this particular customer.  Clearly, this is an incredibly profitable arrangement because the bank is essentially lending the customer their own money at a big margin.  When banks repeat this process over and over again at scale, it can lead to a lucrative business.

But, the success of this business hinges on two very basic assumptions:  (1) the bank will keep enough liquidity in reserve so that when the customer needs to withdraw their funds, they can do so; and (2) the customer is a good credit risk who will make their loan payments as agreed.  It is the second assumption upon which the Texas Ratio is built.

What is the Texas Ratio?

The Texas Ratio is a financial metric used by analysts to predict which banks have the potential to experience “credit” related issues, meaning many customers who are unwilling or unable to make their loan payments.  The ratio was originally developed by Gerard Cassidy and his colleagues at RBC Capital Markets, and they found that when the ratio exceeds 100% or “1”, banks tend to fail.

The formula used to calculate the Texas Ratio is:

Texas Ratio

Non-Performing Assets are loans for which payments are not being made in a timely manner. But, just because a borrower misses their loan payment does not automatically mean the loan is non-performing.  In most cases, a loan will not receive this status until the principal and interest are 90+ days past due.  So, in short, the numerator in this equation is the sum of the principal balance of all loans that are 90+ days past due.

Tangible Common Equity is one measure of a bank’s physical capital, and it is calculated by subtracting a bank’s intangible assets (like Goodwill) and Preferred Equity from the bank’s book value.  And, Loan Loss Reserves is money that is set aside in anticipation of loans that move from non-performing into default.  Another way to think about this is that it’s money set aside for expected future losses.

So, the intent of the Texas Ratio is to see if a bank has enough equity and money set aside to cover any loans that go bad.  Or, put another way, does a bank have enough money to absorb potential loan losses while continuing to meet their other deposit obligations.

Ultimately, one way that a bank can fail is that they make too many bad loans and don’t have enough money to cover the losses.  As was the case with Washington Mutual, if this happens, it can cause depositors to lose faith in the bank and withdraw their funds en masse in a “run on the bank.”  When the money runs out, the bank collapses.

Calculating the Texas Ratio – An Example

To really drive home this point, let’s look at an example of two banks on opposite ends of the risk spectrum.  The data used to calculate the Texas Ratio is publicly available through each bank’s call report and can be found on the FFIEC Website (NOTE:  The example below describes two actual banks, but their names have been withheld for privacy reasons.  In addition, the example is for educational purposes only).

Bank 1 is an online, savings-focused financial institution that has a limited number of banking products available to their customers.  On the deposit side, it offers Savings Accounts and Certificates of Deposit, and it offers residential mortgages and commercial loans on the lending side.  In their June 2020 Call Report that was filed with the FFIEC, they reported $918M in non-performing loans (Schedule RC-N), Tangible Common Equity of $145MM (Schedule RC) and Loan Loss Reserves of $14.3MM (Schedule RC).

Bank 2 is a traditional retail bank with 13 locations across Illinois.  On the deposit side they offer checking and savings accounts and, on the loan side, they offer traditional lending products from personal loans to consumer mortgages.  In their June 2020 Call Report that was filed with the FFIEC, they reported $25.5MM in non-performing loans (Schedule RC-N), Tangible Common Equity of $30.4MM (Schedule RC), and Loan Loss Reserves of $10.8MM (Schedule RC).

To see how the Texas Ratio shakes out for each bank, the following table provides a side by side comparison:

Texas Ratio Calculation

Granted, these two banks were cherry-picked to demonstrate a key point, that banks have very different risk profiles.  Another way to look at the table above is that Bank 1 has $918M in non-performing loans that they could eventually have to take a loss on.  But, they also have $159MM available to cover those potential losses.  Even if all the loans default, they have plenty of money to absorb the losses.

Bank 2 is the opposite.  They have $25.5MM in non-performing loans and only $41MM to cover them, which tells an analyst two key pieces of information:  (1) Bank 2 made some bad loans, and they are suffering the consequences of it; and (2) they haven’t set aside nearly enough money to cover potential losses.  If all the loans were to go bad, it could present a serious financial issue for them.

Remember that a Texas Ratio over 100% is closely correlated with bank failure, so Bank 2 isn’t quite there yet.  To improve their Texas Ratio, Bank 2 will have to pay closer attention to the credit quality of the loans they originate and contribute more money to their loan loss reserve account.  Unfortunately, many banks are reluctant to do this as these funds come directly from income and can result in an operating loss, which shareholders do not always appreciate.

Why Does the Texas Ratio Matter?

We have established that the Texas Ratio is a predictor of potential bank failure, but how does this relate to real estate development and operation? Here are two ways:

First, for banks that continue to invest in their branch network, they could be a tenant in a commercial office or shopping center.  If a property owner is considering leasing space to a bank, the owner would be wise to review the Texas Ratio for the potential tenant as an indicator of financial strength.

Two, commercial property developers tend to carry large deposit balances in their checking accounts.  As such, it is wise to review the Texas Ratio for the bank where these balances are held to ensure they are not in danger of failing.  In the event of a collapse, FDIC insurance only covers balances up to a certain amount.  Above that, the funds could be at risk.


In this article, we discussed the Texas Ratio. We defined the Texas Ratio, walked through the components of the formula itself, and then we covered a detailed example of how to use the Texas Ratio to evaluate the financial strength of two banks. In our Texas Ratio example, we found the publicly available call reports for two different banks and calculated the Texas Ratio for each bank.

This showed that the Texas Ratio can vary widely between banks, and it can also give a quick indication of the financial strength of a banking institution. Finally, we talked about two ways real estate developers and owners can use the Texas Ratio. This ratio can be an important factor when evaluating the strength of potential bank tenants, as well as when evaluating which banks to begin or continue a deposit relationship with.
