Modelling Banking - What am I doing wrong?

I've had trouble recently with Ravel (MacOS) trying to model banking , just as a simple exercise, but I keep crashing Ravel and have to start again which causes me to lose my train of thought. (I'm ADD, Autistic, and Dyslexic, plus some other stuff under the hood.)

Banks need initial Capitalisation -> Asset - Equity

Banks hold Deposits -> Liability - Equity

Banks offer Loans -> Asset - Equity

Banks pay Interest on Deposits -> +Deposits -Equity?

Banks charge Interest on Loans -> +Asset -Liability?

Banks hold Ready Capital for Short Term Liquidity -> Assets? - Equity?

Banks charge Fees for Cash Flow -> +Assets -Liabilities?

What am I not understanding in this equation?

What am I missing?

Which (if any) are Rate statements and how do I place them in the Godley Table? Do I?
