Writing on recent commentary surrounding Britain’s currency, the ever-insightful blogger Polemic Paine perfectly describes what ultimately moves markets — and why my office TV is virtually never on:
I have come to the simple conclusion that the reason that the commentary is so wrong is because very, very few of those commenting actually trade the thing. The reason prices move is because people buy or sell in differing ratios upsetting the equilibrium of the assumed fair price. The reasons that people trade is hugely complex. The drivers behind the individual trading decisions can vary massively. Commentators can not accurately define why GBP is lower or higher unless they have actually spoken to a person who has traded it. Here I am not talking about an FX salesperson who has transacted a trade for someone else, nor even a spot FX trader (who manages flow but rarely knows the ‘why’) but the fund manager, central bank, sovereign wealth fund manager, hedge fund or real money PM, or collection of electrons in an algorithm who actually decided to swing the bat. And funnily enough, practically none of them will ever a) want to tell you b) want the fact that they have traded be known in the first place.
