SCOTSDALE, Ariz.--The asset size at which a community financial institution can generate a meaningful performance advantage has shifted dramatically higher, with the old $1-billion benchmark giving way to roughly $3 billion to $5 billion, according to an analysis by Tristan Green, director at Cornerstone Advisors.
Writing for GonzoBanker, Cornerstone's blog, Green said an analysis of 2015 data showed $1 billion in assets represented a genuine inflection point where financial institutions began producing improved performance. By the end of 2025, however, that performance improvement no longer appeared at $1 billion and instead emerged among institutions with $3 billion to $5 billion in assets.
“The price of remaining relevant has gone up,” Green wrote.
The change reflects the growing fixed costs of operating a modern bank or credit union, including continued spending on digital capabilities, compliance, cybersecurity, fraud prevention, data management and specialized employees, according to Green. While asset size alone does not determine success—and a focused $900-million institution can outperform an inefficient $4 billion institution—smaller institutions can reach a point where mandatory expenses leave little capacity for strategic investment.
Green separated scale into three levels: “survival scale,” at which an institution can remain capitalized, compliant and operating; “reinvestment scale,” where it can also hire specialists, replace technology and absorb failed investments; and “advantage scale,” where it can invest ahead of demand and develop differentiated capabilities. The key benefit of scale, he argued, is not simply lower costs but “optionality”—the financial capacity to reject bad vendor contracts, withstand a credit cycle or continue strategic investments when earnings weaken.
“If every strategic project disappears when earnings weaken, the institution does not have reinvestment capacity, it has good-weather capacity,” he wrote.
Green also cautioned against treating growth itself as the solution. Simply setting a goal to reach a particular asset level does not create scale if expenses and organizational complexity rise at the same pace as the balance sheet. Instead, management should identify what additional size is intended to buy—such as stronger treasury management, improved data capabilities, digital acquisition or a major technology replacement—and determine which costs can grow more slowly than revenue.
Institutions that cannot build those capabilities organically still have options, Green said. Management can accelerate growth, specialize in markets or services where the institution can develop a meaningful advantage, share capabilities through CUSOs, managed services, partnerships and outsourcing, or pursue a merger when there is no credible path to sustainable reinvestment capacity. Those approaches can be combined, but Green warned institutions against trying to pursue all of them while continuing to fund every legacy product, branch and process.
Boards should also establish specific trigger points that force management to reconsider its strategy, such as repeatedly missing deposit growth or operating leverage targets, an inability to fill critical positions or insufficient capital for necessary investments. Ultimately, Green argued, the institutions best positioned to remain independent will not necessarily be the largest, but those capable of continually funding their future.
“The strategic question boards and management teams face is no longer, ‘How big are we?’” he wrote. “It is, ‘Do we have the capacity to fund our future?’”
