One Bank or Several: Weighing Redundancy Against Relationship Pricing

A bank that holds all of your deposits, your operating accounts, your credit facility, and your treasury services tends to price more aggressively across the board, since the relationship's total value to them justifies better terms than any single product would earn on its own. You also get a single point of contact who understands your full financial picture, which matters when you need a fast decision on something outside a standard process, a temporary overdraft accommodation or an expedited wire, for example.

Spreading meaningful balances across more than one institution means an operational issue at one bank, a system outage, a sudden account freeze, or a broader institutional problem, doesn't take down your entire ability to pay payroll or vendors that week. It also means you're not relying on a single bank's ongoing risk appetite toward your industry or your specific business, which can shift for reasons that have nothing to do with your own creditworthiness.

Standard deposit insurance covers a set amount per depositor per bank, and any balance held above that limit at a single institution is technically uninsured in the event of a bank failure, a risk regulators and structured deposit programs address in different ways depending on your size and needs. For a company holding meaningful cash balances, understanding exactly how much of your deposits are actually insured, rather than assuming a large operating balance is fully covered, is worth a direct conversation with your banker rather than an assumption either way.

Rather than choosing purely one bank or fully splitting everything evenly, many companies keep their primary operating relationship, credit facility, and treasury services concentrated with one bank to preserve that pricing advantage, while maintaining a second, smaller relationship purely for deposit diversification and as an operational backup. This preserves most of the pricing benefit of concentration while removing the single point of failure that concerns most boards once deposit size grows past a certain point.

If your deposit balances sit comfortably within insured limits and your credit needs are modest, the operational simplicity of one bank usually outweighs the diversification benefit, since there's less at risk from concentration in the first place. As balances grow well beyond insured limits, or as your credit facility becomes large enough that a single bank's changing risk appetite could genuinely disrupt the business, the case for at least a secondary relationship gets considerably stronger.

A single-bank decision made when the company was smaller doesn't automatically stay right as deposit balances and credit needs grow. Set a specific trigger for revisiting the question, a deposit balance threshold, a credit facility size, or a set review cadence, rather than leaving it as a decision made once years ago and never reconsidered. Treasury structure should track the business's actual size and risk, not the org chart from whenever the first account was opened.

This is also worth revisiting after any acquisition or new entity formation, since inherited banking relationships from an acquired business often sit unreconciled with the parent's own structure for far longer than anyone intends. A deliberate review at that moment, rather than letting two separate banking setups run in parallel indefinitely, usually surfaces both cost savings and a cleaner risk picture.

Pick at least one of these triggers to prompt a fresh look:

• A deposit balance threshold, such as balances growing well beyond insured limits at a single institution.
• A credit facility size at which a single bank's exposure to your company becomes a real concern.
• A set review cadence, so the decision is revisited on a schedule instead of once, years ago.
• A change in the business, such as new entities, new countries or much larger deposit balances.
