10 Pounds – United Kingdom

The United Kingdom entered 2020 with its currency, the pound sterling, still grappling with the profound uncertainty of Brexit. Having fallen sharply after the 2016 referendum, the pound remained sensitive to political developments. The decisive Conservative election victory in December 2019 provided a momentary boost by clarifying that the UK would leave the EU with Boris Johnson’s withdrawal agreement, moving beyond the parliamentary deadlock. However, the focus simply shifted to the immense challenge of negotiating a new trade relationship with the EU by the year-end deadline, keeping the currency volatile and largely subdued against major peers like the US dollar and euro.

The defining event of the year, however, was the global COVID-19 pandemic, which triggered an unprecedented economic and financial shock. In March, as lockdowns were announced and global markets plunged, the pound experienced a severe "dash for cash," plummeting to its lowest level against the US dollar since 1985. This was part of a broader flight to safety, exacerbated by the UK's twin crises of the pandemic and the looming Brexit cliff-edge. The Bank of England responded with emergency measures, including cutting interest rates to a historic low of 0.1% and significantly expanding quantitative easing, which placed further downward pressure on the currency.

By the latter half of 2020, the pound became a bellwether for Brexit trade negotiations. It rallied on hints of a deal and fell on threats of no-deal, demonstrating that Brexit remained the structural driver of sterling's value. The currency ended the year having recovered from its March lows but remained significantly weaker than pre-referendum levels, reflecting the combined weight of the pandemic's economic damage and the anticipated long-term costs of leaving the EU single market. The UK faced a uniquely challenging confluence of a historic public health crisis and a monumental political and economic realignment.
