Fractional reserve banking doesn't really exist any more in the developed world. Banks lend against their capital, not their reserves [1].

thx @soVeryTired, plz excuse lack of financial knowledge. What is the definition of "reserves"?
Are those reserves (capital) fluid? From the tier-1 you refer I get the impression these are real physical assets and in flux. Interesting. How do the UK banks handle market runs? (I must read more about the banking system) In Aus major banks are government backed with minimal competition.
