Hi, I would like to know an estimation on how much did hedge fund
(overall the globally) make when China declared RMB (yuan)
appreciation by 2% on July 21, 2005, and how is that equivalent to the
earning of Chinese labor forces. To be specific, I want to fill in the
blank of this statement,

It was estimated that hedge fund managers pocketed ____ billion
dollars, which is equivalent to the total output by Chinese peasants
for ____ years, from this 'supposedly' suprising announcement.

It's estimated that 145 billion US dollars "hot money" came in
before RMB appreciation.

So the profit is about $3 billion.
Year 2004 the average income of chinese peasant is 2936 RMB,
it's about 350 US dollars. But in China there are 0.9 billion
peasants, so the total income is about 300 billion US dollars.

Thanks a lot for your comment.

While your analysis is insightful, I think hedge fund managers made
much more than this, since they don't just buy and hold Chinese
currency, but they also engage in derivative trading which for every
dollar they put in, the gain realized is much higher than 2%.

Please let me know what you think!

You're right. The hedge fund managers not only get profit from the
appreciation, but also from the chinese estate market and asian
stock markets. It's quite difficult to estimate the exact number 
they got.
