The question over what currency Scotland would use, if it became independent, has plagued debates since the referendum was announced.

While the Scottish National Party (SNP) repeatedly insist that an independent Scotland would retain Sterling, politicians from all other parties have said, "walk away from the UK and you walk away from the pound."

However, speaking to IBTimes TV, Deutsche Bank's FX strategist Oliver Harvey revealed that in any case, there is "no good currency option" for an independent Scotland.

From staying within a currency union, without political unity, or even creating a new Scottish currency, both would be complex and risky.
