derivatives provide insurance against volatility?!
derivatives CAUSE volatility.
We've been dumping long term bonds for short term ones in the past and haven't bought new ones recently. All new buying has been short term ones, after previous long term bonds have expired.
Even this is foolish, because US bonds are trading at historical highs with lowest interest payments on record. Why the f* would anyone buy high, sell low, and buy an instrument with almost zero return?
Yes derivatives cause volatility.You seemed to have clearly misunderstood what i meant by point 4
4
.The derivative market for the currency is developed enough to provide enough insurance against fluctuation.
For yuan it does not exist and Gold is too volatile to allow any meaningful development(Premium quoted very high)
Derivatives are basically hedging instruments.They are used by speculators to induce volatility.
See you need to understand how derivatives work.I would provide a simple example
Suppose you are in possession of a house in hongkong.You need to sell it after a month but want to get at least a specific price for that say the current prevailing price.You could achieve this by buying a put option on your house.By buying a put option you would have an right but not an obligation to sell your house to the buyer of your put.The buyer would buy your put on basis of some premium which you have to pay upfront.If the price of your house increases,you could choose not to exercise your put and your only loss is premium.If the price of your house decrease you could sell it to buyer limiting your loss to that of premium money.
same kind of option called "Call Option" which works in same way but is used if you want to buy something on later date.
another derivative is a forward option but it binds you in an obligation to buy or sell.
*Note:These derivatives are used only for bonds and securities.I gave example of house to make things simple.If you want to trade a real asset like a house you have to convert it into an saleable paper asset which is done by banks and mortaging companies.
So the real purpose of derivatives is to hedge risk and it is used as such by genuine users.
But if only genuine users would be trading in market than there would be nobody to buy derivatives.Here comes the role of speculator who believe that market would swing in his favour.
The volatility occures when an speculator buys naked derivatives i.e for those assets whom he do not possess and shorts his position.
But as my point no 4 has made clear and i have given example of gold for making my position clear.An speculator can induce volatility only when market for that currency is not deep enough.Currently USD8.2trillion is in circulation.It would require someone having hundred of billions of dollar to induce volatility.And financial institutions are not as irresponsible as Fanboi's on internet.they take well reasoned decisions.
For underlined portion
The comment shows that you have only superficial knowledge of economics.
If a country is running a trade surplus it could do following things.
1.It could consume that surplus.
It could be done in following ways.
If the country has a floating currency,it's value could be allowed to appreciate and if it is pegged like yuan.It could be pegged at higher value.
This has following effects
i.It makes Exports costlier.
ii.It makes Imports cheaper.
iii.It provides an incentive for manufacture to serve local market.
these points together lead to decrease in exports and increase in in domestic consumption.
2.It could save that money and keep it in hard currency or treasury bills.
Now given the high dependence your economy has on exports and the fact that your exports are dependent on their low value(if people want quality they would buy german) your government is left with no option but to buy treasury bonds.The rate of buying has gone down because your surplus is also gradually decreasing.If your government allows sudden appreciation of yuan,the manufacturers would simply pack up and leave for other low cost locations like vietnam.the cost of setting up a factory is miniscule compared to cost of running it.Thus your central bank is not run by fools.They know what they are doing and they have to buy US bonds even when it is trading at historical high.
And in Economic terms Short and Long maturity Investments are equal except for sake of liquidity.If chinese government want to sell long term bonds then it has to do so in open market.It has to find a buyer and sell at the price quoted with that buyer which ensures that if it tries to sell a substantial portion of its reserve there would be no buyers for that and it would fetch very low values.While it could redeem Short investments at their face value when they are mature.
