然而，这十年间政治动荡不安，先后历经五任首相，导致政策缺乏连续性，且税收环境吸引力下降，使英国付出了「失去的十年」的代价。前欧盟专员指出，英国过度纠结于与欧盟的距离，反而忽视了美、中、印等全球主要经济体正迅速向前迈进的步伐。
为了挽回劣势并兑现脱欧红利，英国政府正加速推行放宽奖金等待期及IPO流程等改革。但伦敦金融界人士担忧，国内外的多重压力可能分散决策者的注意力，尤其是在欧盟正大力推动改革以强化自身金融业的竞争之际。
However, the past ten years have been characterized by political instability with five successive prime ministers, a lack of policy continuity, and an increasingly unattractive fiscal environment, resulting in the costly reality of a "lost decade." Industry leaders point out that the UK has spent too much time focusing on its proximity to the EU while global competitors like the US, China, and India have forged ahead.
To arrest this drift and realize a promised Brexit dividend, the UK government is accelerating reforms such as relaxing rules on bonus waiting periods and IPO paperwork. Nevertheless, senior City figures worry that domestic and international pressures might distract leaders from supporting the financial sector, especially as the EU actively pushes forward with its own reforms to boost its industry.
