The dramatic rise in support for Scottish independence is nowhere more evident than in GBPUSD implied volatility, which has soared to 3-year highs as The Guardian reports a further poll showing next week's referendum is on a knife-edge with a gap of just 1 percentage point between yes and no. As one 'Yes Scotland' representative noted, "This new Scotland could be less than a fortnight away. But we must not be complacent. The scaremongering, dissembling and misrepresentation of the no campaign will be ramped up as we approach polling day." Of course, Scotland is not the only EU nation seeking separation, as we illustrate below, and as Goldman Sachs notes, there could be a broader impact on the risk premium across Europe as Scottish independence leads to other calls for more regional autonomy.
