In 1605, Scotland’s currency situation was complex and unstable, a legacy of its status as an independent kingdom with its own monetary system. The primary unit was the Pound Scots (
£Scots), but its value had drastically depreciated against the English Pound Sterling, with an exchange rate of approximately £1 Sterling to £12 Scots. This devaluation was the result of centuries of coinage debasement, where Scottish monarchs reduced the silver content in coins to fund state expenses, eroding public confidence and causing inflation. The coinage in circulation was a mixture of underweight domestic issues and a flood of foreign coins, particularly French
écus and Dutch
leeuwendaalders, which were essential for international trade but added to the monetary confusion.
The situation was further complicated by the Union of the Crowns in 1603, when King James VI of Scotland also became James I of England. While the kingdoms remained politically separate, the monarch now resided in London, creating a de facto economic pull toward the stronger English currency. In daily commerce, people had to navigate a dual-currency reality: rents and large transactions were often calculated in the stable Pound Sterling, while physical payment might be made in the fluctuating Pound Scots. This created practical burdens for trade and debt settlement between the two nations, highlighting the growing economic disparity.
Despite the political union, no monetary union was established in 1605. James I had proposed a uniform coinage for both kingdoms, but this was met with resistance from the English Parliament, which feared the weaker Scottish currency would destabilise their economy. Consequently, Scotland continued to operate with its fragile and heterogeneous monetary system. The inherent instability and the king’s absence from Edinburgh hindered effective fiscal reform, leaving Scotland in a financially subordinate position and setting the stage for future economic pressures that would culminate in the full Parliamentary Union of 1707.
