I know the Pound Sterling rose fairly significantly over the past several days on speculation of a yes vote, so the world of currency trading appears to have viewed it as an economic positive for Scotland to leave the UK.
No. GBP tanked on word of a poll showing Yes jumping ahead suddenly. As Westminster moved to try and turn public opinion around and subsequent polls shows that the NOs were still ahead (that one poll was probably just wrong) everyone backed away from the ledge and GBP rebounded.
