Short version: 72 banks are headquartered in Michigan, holding $72.49 billion in total assets between them as of June 30, 2026. The median one holds $470M. The median Michigan bank earned 1.17% on its assets against 1.23% for the median US bank, on a margin of 4.05% against 3.83%.
How many banks are headquartered in Michigan?
72 banks filed an FFIEC call report for the quarter ending June 30, 2026 with a head office in Michigan. Between them they reported $72.49 billion in total assets. That is a count of charters headquartered there, which is not the same as a count of banks operating there: a bank chartered in a neighboring state with branches across this one is counted in the state its head office sits in, and its whole balance sheet goes with it.
Non-insured non-deposit trust companies are left out of every figure on this page. They hold a charter and file a report, but they take no deposits and make no loans, so a funding cost or a margin computed for one of them is a ratio over an empty denominator. The same exclusion is applied to the national medians, so the two columns below are measured on the same basis.
Michigan bank benchmarks against the national median
Each figure is the median across banks headquartered in Michigan, beside the median across every bank in the country that filed for the same quarter. The gap is in percentage points.
| Metric | Michigan | US median | Gap | |
|---|---|---|---|---|
| Return on assetsNet income as a share of average assets. The summary number. | 1.17% | 1.23% | −0.06 pp | In line |
| Net interest marginNet interest income over average earning assets: the spread business. | 4.05% | 3.83% | +0.22 pp | Better than the US median |
| Efficiency ratioNoninterest expense per dollar of revenue. Lower is leaner. | 64.37% | 61.81% | +2.56 pp | Worse than the US median |
| Cost of fundsInterest expense over interest-bearing liabilities: what the money costs. | 2.06% | 2.34% | −0.28 pp | Better than the US median |
| Loans to depositsHow much of the deposit base is lent out rather than held in securities. | 83.87% | 80.16% | +3.71 pp | Higher |
| Tier 1 leverage ratioTier 1 capital over average assets, with no risk weights applied. | 10.28% | 10.96% | −0.68 pp | Lower |
Source: FFIEC call reports for the quarter ending June 30, 2026. Michigan medians are computed across all 72 banks headquartered there, at every size. National medians are computed across every filing bank, matching the figures published in the BankingLens benchmark articles for the same quarter.
What the numbers say
The median bank in Michigan pays 28 basis points less for its money than the median US bank, 2.06% against 2.34%, and earns 22 basis points more on the spread, 4.05% against 3.83%. Cheap deposits reaching the margin is the strongest position on this page: the funding advantage is being kept rather than competed away on the asset side.
On the expense side it spends 64.37 cents to earn a dollar against 61.81 nationally, a heavier cost base, with return on assets at 1.17%, level with the country.
The median Michigan bank lends out 83.87% of its deposits against 80.16% nationally, so more of what it takes in is lent out rather than held in securities, and carries tier 1 leverage capital of 10.28% against 10.96%, a thinner cushion than the median US bank. Neither of those has a good direction on its own. A high loan-to-deposit ratio means a bank is putting its funding to work, and also that it has less room left before it has to buy more; capital beyond what a bank needs to absorb its own losses earns very little.
Banking in Michigan is unusually dispersed. The largest charter headquartered there, Northpointe Bank of Grand Rapids, MI, holds 10.4% of the state's bank assets, and the five largest hold 42.3% between them. The median bank holds $470M.

Methodology
- Universe. Every US bank that filed an FFIEC call report for the quarter ending June 30, 2026 with a head office in Michigan, at every asset size. There is no size floor: a median that excluded small banks would not describe the place.
- Exclusion. Non-insured non-deposit trust companies (FFIEC peer group 401) are left out of every statistic, here and in the national column. They take no deposits and make no loans, so their ratios have no meaning and a handful of them would move a small state's median a long way.
- Median floor. A local median is published only when at least 8 banks are headquartered there. Below that the median is one institution's number rather than a distribution, so it is withheld and the banks are listed individually instead.
- National median. Computed across every filing bank on the same basis, and checked against the figures the BankingLens benchmark articles publish for the same quarter, so the two can never disagree.
- Where assets are counted. At the charter's head office, as filed. A national bank headquartered in this state contributes its entire balance sheet to the state total regardless of where the deposits were gathered.
- Source. FFIEC Central Data Repository, joined to bank identity - name, city, state and RSSD id - from the same filing. Figures are as reported by each institution and are not adjusted or restated.
- Reproducibility. This page is generated by
_tools/seo/build_state_pages.mjsfrom the published dataset. It is not hand-maintained, and it carries no figure that was typed in.
