Anchor bank status unlocks triple corporate wallet share

Being corporations’ primary bank means managing the bulk of their money.

Nearly 95% of bank clients reallocate up to 25% of their banking wallet share each year, with anchor banks assured continued patronage.

Corporates consolidate about 73% of their wallet with an “anchor bank” or house bank. These are the primary banks where companies engage in global liquidity, foreign exchange, or M&A financial activities, according to a study by McKinsey & Co. published in September 2026.

In contrast, other banks or financial service providers are relegated strictly in revolving credit facilities or what McKinsey calls operational utility roles, such as in-country cash management and payroll, the management consulting firm said.

“Corporates actively rationalize their banking ecosystems, often prioritizing operational efficiency over complex multibank systems,” McKinsey & Co. wrote in the report, “Anchor or drift: What it takes to capture wallet share in 2026.”

Institutional investors and financial sponsors, meanwhile, consolidate 60% and 55% of their wallet allocations on their anchor banks, respectively.

“Achieving anchor status can result in a massive upside, tripling the share of wallet and offering opportunities to sponsor portfolios,” McKinsey said.

To become an anchor bank and avoid being relegated to utility status, McKinsey & Co. advised financial service providers to strategically choose where to compete and deploy optimized coverage models and differentiated products to target high-potential clients.

McKinsey said not to assume that client relationships are guaranteed. “When they move, they move hard,” the firm warned.

Institutional investors move 17% of their wallet share per cycle, and financial sponsors move up to 25% each year. A lead position one year can erode the next, McKinsey said.

For corporations, wallet rotation is due to performance-based rotation, event-driven rotation, or strategic rebalancing.
