F*ck me JP
I just thought I'd got my head round it and you've confused me.
In my IBM days we went punting on the canal at Hook and I nearly drowned cause I got my punt stuck in the mud.
I know it's imaginary money, the point I'm trying to make is that it's at the margins where it matters. It's only the difference betwen winners and losers where it can hit the real economy.
This could be zero - I think it's probably a big number. The other bit that matters is the (taking the casino analogy) the house cut. This could also be substantial.
BTW how are you PM me with where you're up to.

OK,I'll explain things as best I can. Derivatives appear & disappear from no-where. They are not 'real' money. The secret is that whilst the contracts are 'in the system', they act as if there are.
Lets do an analogy.Think of a rowing race (Oxford vs Cambridge, if you like).The paddles dip into the water briefly & then propel the boat forward according to the muscle power (leverage) of the rowers. Most of the action is above the water (the 'leveraged' money). That is the way it works.
Suddenly a rower gets his 'real money' paddle caught in the mud. Let us call him 'Mr Lehman'. The momentum of the boat plus the 'leverage' on his oar propels him straight out of the boat & into the water before he can say 'Oh f**k!'. Think of a big wide arc and a rapid splash & you'll get the picture.
Mr 'L' (unfortunately) hits some oars on boats coming the other way. Then we have a big 'up & downer' while everyone tries to get their boats upright again.
Then everyone has to figure out how to get the race back on schedule They were starting to figure it out but whilst this was going on, the team from Iceland rowed into a rock (loans) & foundered with lots of blubbering noises.
Meanwhile the Health & Safety crew (AKA the Gobermint ) are now sculling around in their rubber dingies & trying to both pull people out of the water & also string wet black & yellow tape everywhere because it be an 'incident' & they don't want to get caught short on not having been on top of the accident sooner. One of the things they are also starting to figure out is, these boats were only designed to hold water if they were moving VERY fast.
Does this help???
