What is the z-score of a banking system?
Z-score compares the buffer of a country's commercial banking system (capitalization and returns) with the volatility of those returns. It captures the probability of default of a country's banking system.

Bank of America's altman z-score for fiscal years ending December 2019 to 2023 averaged 0.4. Bank of America's operated at median altman z-score of 0.3 from fiscal years ending December 2019 to 2023. Looking back at the last 5 years, Bank of America's altman z-score peaked in December 2020 at 0.6.
The popularity of the z-score stems from the fact that it has a clear (negative) relationship to the probability of a financial institution's insolvency, that is, the probability that the value of its assets becomes lower than the value of its debt. A higher z-score therefore implies a lower probability of insolvency.
A Z-score that is lower than 1.8 means that the company is in financial distress and with a high probability of going bankrupt. On the other hand, a score of 3 and above means that the company is in a safe zone and is unlikely to file for bankruptcy.
The basic principle of the z-score measure is to relate a bank's capital level to variability in its returns so that one can identify how much variability in returns can be absorbed by capital without the bank becoming insolvent. A higher value of the z-score means lower bank risk.
Boeing Co BA's altman z-score for fiscal years ending December 2019 to 2023 averaged 1.6. Boeing Co BA's operated at median altman z-score of 1.5 from fiscal years ending December 2019 to 2023.
A Z-Score is a statistical measurement of a score's relationship to the mean in a group of scores. A Z-score can reveal to a trader if a value is typical for a specified data set or if it is atypical. In general, a Z-score of -3.0 to 3.0 suggests that a stock is trading within three standard deviations of its mean.
FAQS on Z-Score
0 is used as the mean and indicates average Z-scores. Any positive Z-score is a good, standard score. However, a larger Z-score of around 3 shows strong financial stability and would be considered above the standard score.
The Altman Z Score formula is (1.2 x A) + (1.4 x B) + (3.3 x C) + (0.6 x D) + (0.999 x E). Here, A is working capital / total assets, B is retained earnings / total assets, C is earnings before interest and task payment / total assets, D is equity market value / total assets, and E is total sales / total assets.
What is the z-score for dummies?
Z-score is a result of standardizing an individual data point. Simply put, a z-score gives us an idea of how far the data point is from the mean measured in terms of standard deviation(σ). For instance, a z-score of 2.5 indicates that the value is between 2 to 3 standard deviations from the mean and is not so common.
- 95% Two-Sided Z-Score: 1.96. One-Sided Z-Score: 1.65.
- 99% Two-Sided Z-Score: 2.58. One-Sided Z-Score: 2.33.
- 90% Two-Sided Z-Score: 1.64. One-Sided Z-Score: 1.28.
A high z -score means a very low probability of data above this z -score. For example, the figure below shows the probability of z -score above 2.6 . Probability for this is 0.47% , which is less than half-percent. Note that if z -score rises further, area under the curve fall and probability reduces further.
Moody's has a Altman Z-Score of 6.18, indicating it is in Safe Zones. This implies the Altman Z-Score is strong. The zones of discrimination were as such: When Altman Z-Score <= 1.8, it is in Distress Zones.
The Z-score is a heuristic formula developed to estimate the chances of a company going bankrupt. 1. The formula looks at working capital, retained earnings, and EBIT, all relative to a firm's total assets. A Z-score above 3.0 signals good financial health, while a score below 1.8 suggests a high risk of bankruptcy.
The Z Score is calculated by multiplying each of several financial ratios by an appropriate coefficient and then summing the results. The ratios rely on the following financial measures. Use balance sheet figures from the end of the reporting period for all Z Score calculations.
To study the bank failure prediction, we use Discriminant Analysis (DA) and check the robustness of the results using Logit Regressions (LA). We also perform an additional analysis using an out-of-sample examination to support the accuracy of the prediction model.
Lockheed Martin's operated at median altman z-score of 4.9 from fiscal years ending December 2019 to 2023. Looking back at the last 5 years, Lockheed Martin's altman z-score peaked in December 2021 at 5.0. Lockheed Martin's altman z-score hit its 5-year low in December 2023 of 4.7.
Z-score is calculated in number of standard deviations. A Z-score above 2 or below -2 is considered statistically significant.
United Airlines Holdings has a Altman Z-Score of 1.14 indicating it is in Distress Zones. Study by Altman found that companies that are in Distress Zone have more than 80% of chances of bankruptcy in two years.
Why is z-score so important?
It turns out that it's a natural question to ask for some value, "How many standard deviations is it from the mean?". The z-score is the answer to the question. The z-score is particularly important because it tells you not only something about the value itself, but also where the value lies in the distribution.
The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions.
Z-scores are standard deviations. If, for example, a tool returns a z-score of +2.5, you would say that the result is 2.5 standard deviations. Both z-scores and p-values are associated with the standard normal distribution as shown below.
In its initial test, the Altman Z-Score was found to be 72% accurate in predicting bankruptcy two years prior to the event. In subsequent tests over 31 years up until 1999, the model was found to be 80-90% accurate in predicting bankruptcy one year prior to the event.
These risks are primarily reflected through its low Altman Z-score of 1.65.
