@alexcobham - but that scenario so would be extraordinary, and framing it a way that's so easily misunderstood doesn't aid understanding.

@MForstater As you know, Swiss piece is an attempt to get beyond Zambia story and understand if there's a broader problem. Clearly there is.

@MForstater Swiss prices appear abnormal at both ends; hence the margin especially so.

@MForstater If we write off all Swiss-declared prices as 'extraordinary', the problem doesn't go away. Much though you might like it to!

@MForstater You'd agree, I hope, that some the scenarios I suggested have implications for dev country exporters' potential to benefit...

@MForstater ...even though I specifically excluded the cases which bear directly on their getting a fair price originally.

@MForstater My view, fwiw, is that only by further research can we hope tovbe more confident about nature of pricing and scale of losses.

@MForstater Simply ignoring the Swiss prices as 'extraordinary' - despite the consistent pattern over time, countries and commodities...
