What SVB Taught Me About Liquidity

A month out from the SVB collapse, the immediate panic has subsided but the lessons haven't. The biggest one for me is a distinction that sounds simple but changes how I think about risk. SVB was well-capitalized. It ran out of cash. Those are two very different problems.

Capital vs Liquidity

Before SVB, I understood capital ratios conceptually. Banks are required to hold a certain amount of capital relative to their assets, and regulators track this closely. SVB met those requirements. By standard measures, it was a well-capitalized institution.

But capital ratios don't tell you whether a bank can meet withdrawal demands on any given day. That's liquidity, and it's a fundamentally different question. Solvency means your assets exceed your liabilities. Liquidity means you can convert those assets to cash fast enough to meet obligations when they come due.

SVB's assets were locked in long-dated securities that had lost market value. Selling them would mean realizing billions in losses. Borrowing against them was possible, but not at the speed the run demanded. The bank was solvent in the accounting sense. It just couldn't produce $42 billion in cash in a single day. Nobody could have.

What this drove home for me is that capital adequacy and liquidity adequacy are separate risk dimensions. A bank can pass every capital test and still fail if its assets can't be liquidated quickly enough. The two risks require different monitoring, different stress tests, and different contingency plans.

The Speed Problem

The part of SVB that broke every existing model was the speed. Forty-two billion dollars left in one day. Before this, the standard scenarios for deposit outflows assumed a gradual process. Clients get nervous, some start moving money, the bank has days or weeks to respond.

Mobile banking and digital transfers changed that math completely. A client who would have driven to a branch and waited in line can now move six figures in thirty seconds from their phone. Multiply that by thousands of clients getting the same message in the same group chat, and the withdrawal velocity is orders of magnitude faster than anything the models anticipated.

Social media was the accelerant. VCs were telling portfolio companies to move their money on Twitter and in private messaging groups. The information asymmetry that used to give banks time to respond evaporated. Everyone knew simultaneously, and everyone could act simultaneously.

The irony isn't lost on me. The digital tools that make banking more convenient for clients also make banks more vulnerable to runs. Every improvement in access speed is also an improvement in exit speed. I don't think the industry has fully grappled with what that means for how we model deposit stability.

The Insurance Gap

The other thing SVB exposed is how poorly understood deposit insurance is, even among sophisticated depositors. The $250,000 per depositor per institution limit is straightforward enough. But most of SVB's depositors were well above that limit, and many of them apparently didn't know there were ways to extend coverage.

Different ownership categories at the same bank can each be insured separately. Joint accounts, revocable trusts, IRAs, each has its own $250,000 of coverage. Beyond that, products like ICS, the IntraFi Cash Service, let depositors spread large balances across a network of banks so that each portion stays within the FDIC limit. The depositor deals with one bank, but the money is distributed behind the scenes.

After SVB, I had more conversations about FDIC coverage than in the entire prior year. Clients who never thought about it suddenly wanted to understand how it worked and whether they needed to move money. These products existed before the crisis. They just weren't top of mind until people had a reason to care.

What Changed

A month later, I think about banking risk differently. Capital adequacy matters, but liquidity is what keeps the doors open. Digital banking changes the speed assumptions that decades of risk models were built on. Deposit insurance is misunderstood by the people who need it most.

The banking system is fundamentally sound. What's new is how fast confidence can evaporate and how quickly clients can act on that loss of confidence. That's the gap we're all trying to figure out how to close.
