Saying deposits are larger than loans means absolutely nothing. Each loan creates an equal deposit, and then you add the initial deposit. What matters is the amount of cash backing the loans, because the deposit accounts are basically IOUs for that cash. There are more IOUs than cash.
Yes it does. They just create the deposits when they create the loans. That is the point you are missing. You wrongly think the reserve ratio means banks can only lend out 90% of their current reserves. What it actually means, according to the Federal Reserve itself, is that banks must have enough reserves to satisfy 10% of their net transaction account liabilities. That means that if their current reserve ratio is above 10%, they can create more loans (and thus demand deposits) until the ratio is down to 10%.
The loan is often in the form of a check, which is then deposited...into a demand account. So pretty much always. Rarely do people withdraw cash from the loan, especially for amounts of significant size.
Like I said, they would never write a check the size of their entire cash reserves.
Let me set up the scenario for you again.
There is an initial deposit of $100 cash into a bank. The bank takes the cash, then creates a demand deposit account for the depositor. This is the result:
Assets
Cash.....................$100
Total Assets...........$100
Liabilities
Demand deposits....$100
Total Liabilities.......$100
Now assume the reserve ratio is 10%. What is the ratio now? Cash=100, liabilities=100. 100/100 = 1 = 100%. Under the law, the bank has every right to bring that reserve ratio down. There is absolutely no reason they cannot do the following (and in fact the following is exactly what they do):
The bank makes loans totaling $900. Nobody is given cash, they are ultimately given demand deposits, which the bank can create due to the reserve ratio not being 100%. The result?
Assets
Cash.....................$100
Loans....................$900
Total Assets...........$1000
Liabilities
Demand deposits....$1000
Total Liabilities.......$1000
What is the reserve ratio now? Cash/Demand Deposits = 100/1000 = 0.1 = 10%. And there you have it. The bank has made $900 in loans based on its initial $100 cash reserves.
But wait--it gets better. What if the bank wants to loan another $100? If it tries to do this, it will be below 10% reserves. However, the bank can easily do it anyway? How? It borrows $10 in cash from another bank. The result?
Cash=$110
Demand Deposits=$1100
Cash/Demand Deposits=110/1100 = .1 = 10%.
And look at that. More money creation. Now tell me: where did the bank break the law in doing any of this? What law was broken specifically?
I assume you have no answers to those questions. To further prove my point, here are a myriad of sources backing my claim that this is what happens:
Michael Kumhof of the IMF
"...banks do not have to wait for depositors to appear and make funds available before they can on-lend, or intermediate, those funds. Rather, they create their own funds, deposits, in the act of lending. This fact can be verified in the description of the money creation system in many central bank statements, and it is obvious to anybody who has ever lent money and created the resulting book entries."

Adair Turner, Chairman of the FSA in the UK:
"But in fact they donÂ’t just allocate pre-existing savings, collectively they create both credit and the deposit money which appears to finance that credit."

Merryn Somerset Webb, editor-in-chief of Money Week, The Financial Times:
"Every time they expand their lending they increase the supply of money in the economy. And every time they contract lending they reduce it"

Alan Holmes, then Senior VP of Federal Reserve Bank of NY, 1969:
“In the real world, banks extend credit, creating deposits in the process , and look for the reserves later.”
