I believe the correct description is:
Based on a typical capital reserve ratio of 1:10, By depositing your $250K, you are giving them the liberty to loan another 225K. So if you deposited $1M, they can now lend $0.9M.
$0.9M worth of loans for $1M deposit at 1.9%PA would yield the bank 17.1K worth of interest a year, while you get around 10K if its a FD of 1% at 1M? Their net profit is $7.1K from your $1M.
Banks can only loan what they have. To loan money out, the money either comes from deposits, or borrowed from other banks. They do not magically create dollar bills to loan out. What is meant by the bank creating money is that there are more assets in the economy, matched by more liabilities.
