a) You seem to ignore the fact that speculators as traders do 2 things buy and sell. The easiest thing in trading (ask Milti he knows) is to buy. The most difficult thing is to sell with profit. It's not as easy as you think with the speculators doing the job with computers. Trading with computers still carries with it the fundamental principle that the easiest thing is to buy and the most difficult thing is to sell with a profit.
Telling us that the speculators do as they please pushing the values down as they please (as if they gain from selling at lower prices) is fundamentally wrong, sorry.
Exactly ...... they sell with one hand and buy with the other ......... that is the way I understand it! Maybe I am wrong but it seems logical. They use client’s money ....... and the bank’s deposits, to buy and sell. You are trying to align the normal commercial trading process, with currency speculation ..... and I don’t think you can, they are fundamentally different. They don’t put up x billion £’s for sale and wait for a buyer ....... they ARE the buyer!
They don’t send e-mail’s asking their clients what they want to do ...... they have the money and act quickly, chasing one another. They speculate (sell) and create their own prediction (the product reduces in value) ..... the client/bank keeps their fingers crossed ............ that is why they get six figure salaries! When they buy the process is reversed.
Billions of £’s sold and billions of Euro’s used to buy, in fractions of a second ...... and the speculators are the ones that initiate the process. (The algorithms are the prize for any bank .....a microsecond shaved off the processing time can mean the difference between a profit and a loss. Even the length of the ‘cable’ (Fibre Optic) between the banks computers and the Market computer has significance.)
They are transferring part of the ‘value’ in one currency, to the other. As you say net sum zero BUT ................ if they can sell the £ and buy with the Euro in less than a blink of an eye.......... with the speed of these computers the difference is milliseconds or maybe even microseconds, and the profit small. But do that thousands of times a day with huge amounts of money and you can make a very handsome profit for both the bank, the Client and the ‘trader’. Does sod all for the real economy ...... it is a process that makes money out of money ..... they produce nothing.
Other computers see the transaction and they react to a selling/buying spike, but there are breaks on the system otherwise you would have an avalanche of selling one currency and it would crash ....... that would benefit nobody!
As I say, this is how I understand the system works. If you can show me it works another way with your explanation then I am quite content with accepting your explanation as just as valid as mine but, just like mine, .......... open to questions?
b) If Catalonia gets independence and then joins the EU automatically (it cannot do otherwise anyway) what's the problem (economically) for the EU?? zero minus zero=zero, no?
Now imagine Brexit, and then Scotland voting to remain in the EU. Woww! That would mean a totally separate country. Borders and millions Euros in building and controlling physical borders, restricting move of goods and services and people and all sorts of bad economics.
Moreover most probably Scotland would need to adopt the Euro, or just issue it's own currency.
Now give me one reason why such news (which was REAL news a few months ago and might be REAL news again after Brexit) would not push the value of the GBP down to it's limits.
I think your assumption is wrong. I seem to remember that when Sturgeon started with that proposal the Scot's were told by the EU Commission that they would NOT remain a member of the EU and would have to go through the membership process as an independent state. This could take up to ten years, I assume that the same would apply to an independent Catalonia?
Another point to consider is that the Scottish referendum was a referendum approved by the UK Parliament, the Catalonian referendum has been declared illegal by the Spanish Parliament. Just like Crimea’s referendum ......... it would not be as ‘they’ desired .......... therefore the self determination of the people will be ignored anyway!
Have you not got the reaction the wrong way round? Surely if the referendum in Catalonia was a vote to leave it would be a Catxit and the Euro would fall in value against the £? The reverse of what you say. It would be bad news for the EU as it would show cracks in the structure and impact the financial stability of Spain.
