>About 37,000 customers accounted for nearly $157 billion or 74% of the bank's assets with an average account size of over $4 million
So it seems the opposite is almost true, because the accounts are valued so high with generally more flexible account holders, they're able to move swiftly
GP is talking about the majority of accounts, and the number you cite is a percentage of funds. If 98 people have an account with $1 in it and one person has an account with $102, then 51% of the bank's assets are in accounts > $100, and the vast majority of accounts have $1.
I would expect larger accounts to make the percentage of deposits in accounts with > $250K to be higher than the percentage of accounts with > $250K because that's how numbers work.
