> No matter how much capital the hedge funds can muster it will be puny compared to PBoC resources This is incorrect. Hedge funds borrow and create temporary money by writing derivative contracts such as options, futures & swaps. It is by this logic they can actually muster more funds than the PBOC in aggregate. Quite simply the market for currencies is bigger than the PBOC and the hedge funds, but there are more hed…
There is relative little rmb outside the country. Not everyone can just go inside China and borrow yuan and buy USD. If you are talking about non deliverables, who will be your counter party if everyone wants to go short?
There doesn't need to be any, so long as the counter currency exists (the USD, EUR, JPY, etc) there can be a control against the onshore yuan, whether it trades or not.
There is always a counter party, It can be created using swaps to other currencies and to other companies actual cash flows.
I wouldn't want to argue against this topic excessively because its a fairly clear cut case of 'this time its different' with China, primarily through marketing.
I'd point out that on previous occasions in history, the gold & silver pegs, various cross currency pegs. It has always been the case the price setter has assumed they were bigger than the market and it has always turned out the opposite. It is also because the market can stand the test of time. This combined with today's use of leverage & derivatives is an even more dangerous combination.
Markets always assume the correct rate, because if not there is something that can be profited from.
None of what I say precipitates bias, I'm not against China's rise. I even believe the GDP numbers out of China, as I mention in another comment on this page. This is just the basis of how markets work. The predicate of your assumption is the PBOC is bigger than the market for Yuan trade and this is incorrect. In something as liquid as a currency a counter party will always be available.
