If you have enough assets, Chase will absolutely lend against that collateral.
“Enough” is likely the key word. But if you have business or personal accounts with over a couple million (and certainly $10+ million), I would be shocked if someone higher up than a clerk hadn’t personally reached out to you, tried to take you out to coffee, and let you know the perks applicable to your personal situation they can provide you that you can’t find on a website.
Sure, they likely weren’t as enticing as SVB’s perks nor as willing to lend to an account that had $0 yesterday and millions the next, but they absolutely will offer personal loans/mortgages against stock compensation on the guarantee you keep your account with them above a certain threshold, etc.
