It's not true, as a previous poster said, that all banks can do this. They can't. Lloyds can only lend what they have themselves available to give. They can't create new currency. But a central bank, controlled by a government, can. The Federal Reserve, or the Bank of England.
Unless you are using "currency" in a very narrow technical way, that excludes all the stuff we have in our bank accounts, then it is wrong to say banks don't create money. There is a technical sense in which bank money is not "currency", but we are not talking about currency in this thread, we are talking about money. Other posters have already alluded to the fact that 97% of money in existence is created out of thin are by commerical banks, and that information comes from a paper that was published on the Bank of England web site in 2013. (I assume it's still there for anyone who wants to look, it is fascinating.)
Regarding in particular:-
Lloyds can only lend what they have themselves available to give.
The Bank of England paper is quite emphatic that commercial banks do not lend out money they already have, they create new money out of thin air every time they make a loan.
To ensure the integrity of the banking system, banks do have to balance their books, and a major way of achieving that is having deposits that cover their liabilities. But the liabilities come first, they scramble around for deposits after the fact. They don't first get the deposits then lend them.
