Does anything a politician does in this country really have an impact on the exchange rate?
Not necessarily but what they say do carry some weight in terms of what they possibly may or may not know. Investors and or speculators base a large part of their decision making on the fundamentals of a country's economy.
When looking at the fundamental one can get an idea of what a country's economy is like and where it might be heading. The biggest problem however is to get your timing right and for this they keep their ears to the ground i.e. keep a watch for signals to indicate a shift in these fundamentals. One of the more important factors having an effect on these fundamentals are the various news events. These include the normal run of the mill news events like for example the monthly unemployment figures and the like but also the adhoc news events which could have an effect on the fundamentals of a country's economy.
So when a person who is perceived to be in the know say and or do something it could result in a direct effect on the market. Just look at the governors of the central banks who quite often will talk a currency up and or down meaning that they will say things in an indirect way in order to move the market in a certain direction. A good example of this is when they say that they will lift interest rates aggressively without actually doing so. The mere mention of the possible actions will move some investors/speculators to action.
So yes, what politician and or business leaders do and or say can have direct effects on the market to a greater and or lesser degree.
I am starting to think local news dissemination is impeccably timed with like the Yellen FOMC thingie. In other words, correlation does not imply causation.
The Rand does not exist in a vacuum meaning that any movement on the Rand is not always attributable to something that happened in SA. The Rand is tied to the Dollar, Euro and the Pound [as well as all the other currencies but these are the majors] and as a result will move due to news events in those countries.
A movement on the Rand, whether positive and or negative, should thus not always be tied to events in SA as it could easily have been news which for example effected the Dollar and thus the Rand.
Nobody knows where the rand is gonna be in 12 months, but we all know the game is rigged.
There are just to many variables involved to make an accurate prediction. Some do get it right but then again, it will go either up or down so some will have to be right if you think about it.
In regards to the markets being rigged. To some extend yes as the larger players can and do move the markets and some do have more insight than others. These players can however not move the markets for long. They might be able to cause a spike or so with news events by moving large amounts of capital around but the market quickly finds its balance again. Many central banks have tried moving their own currency and have failed miserably as the market forces are just to big.
So yes it might be rigged to some extend but never for very long.
