Affected by the COVID-19，the UK economy has entered a recession cycle for the first time in a decade，with both supply and demand hindered. The investment is further transferred to the EU，the trade is heavily dependent on foreign enterprises，and the trade structure is too dependent on China，the US and Europe market. The labor market is weak and temporary unemployment has soared. The epidemic has not only impacted the service industry，resulting in a downturn in the financial market，but also dealt a considerable blow to the manufacturing industry. The UK government has provided liquidity to the market and helped out enterprises and employees through fiscal policies （i.e.，direct subsidies，government-guaranteed loans） and monetary policies （i.e.，interest rate cuts and expansion of asset purchases），so as to stabilize employment and prevent economic recession. However，the implementation has been relatively limited，and has caused fiscal deficit and the continuing surge of public debt，thereby making systemic risk increase significantly. Whether the “post-epidemic era” economic recovery plan can be successfully implemented，whether the financial market can stabilize and recover to stabilize investor confidence，whether a trade agreement with the EU can be reached，these are important variables that determine the long-term development of the UK economy.
