金融服务相关的好处:打破这种关系最终将使英国能够独立地与发展中国家谈判，并在这些市场进行投资(O ‘Grady, 2016)。由于英国必须遵守欧盟框架，谈判十分艰难，英国无法利用其强大的金融支柱来促进其金融服务。这将为金融服务提供商提供机会，并可能导致该行业的增长，否则该行业将陷入停滞。长期利益:在短期内，英国肯定会有一些问题需要解决。然而，从长远来看，考虑到英国强劲的经济，这些问题是可以克服的，与加入欧盟相关的负面影响也不会存在。当然，政治方面将发挥更大作用，以克服短期的负面影响。一些显而易见的因素，如预算的节省，可以用来克服短期损失，从长期来看，因为事情将稳定的利益将为英国(Mendez-Parra, Papadavid & Te Velde, 2016)。考虑到已经讨论过的益处，英国已决定退出欧盟。然而，英国退欧也有负面影响。下面讨论了英国退欧的一些负面影响。
与欧洲国家的贸易:欧洲国家是英国的巨大市场。作为欧盟的一员，英国的优势在于没有税收壁垒，因此英国企业具有一定的优势。然而，退出欧盟将剥夺这些好处，并使英国企业难以维持其市场份额。由于英国经济近一半的出口依赖于对欧洲国家的出口，应对这一挑战对英国来说将是相当困难的。英国的外商直接投资:欧盟拥有巨大的潜力。因此，它吸引了大量的外国直接投资。英国是欧盟最稳定的经济体，吸引了大量的FDI，成为欧盟各国考虑FDI的首选(House of Commons Tresury Committee, 2016)。英国未来吸引外国直接投资的能力将会下降，这方面将产生相当大的影响。预算计划将会受到干扰，从长远来看会产生巨大的影响。
Financial Services Related Benefits: The breaking up of the tie up will eventually enable United Kingdom to negotiate independently with the developing nations and invest in these markets (O’Grady, 2016). As UK had to abide by the EU framework, the negotiation was difficult and UK could not leverage upon its strong financial backbone to promote its financial services. This will provide opportunities for the financial service providers and may lead to growth in this sector which otherwise has become stagnant. Long Run Benefits: There will certainly some issues that UK may have to address in the short run. However, in the long run, given the robust economy of UK, these issues can be overcome and the negative aspects associated with being part of EU will not be there. Certainly, the political aspects will play a greater role in order to overcome the short term negative impact. Some of the factors that are evident such as savings in the budget can be utilised to overcome the short term losses and in the long run as the things would stabilize the benefit would be there for UK (Mendez-Parra, Papadavid & Te Velde, 2016). The decision to exit of UK from EU has been taken, considering the benefits that have been discussed. However, there are negative aspects related to Brexit. Some of the negative effects of Brexit have been discussed below.
Trade with European Countries: The European countries are huge market for UK. Being part of EU, UK had the advantage that the tax barriers were not there and thus the corporate of UK had certain level of advantage. However, the exit from EU will take away these benefits and would make it difficult for corporate from UK to maintain its market share. With UK economy relying on almost half of its export to European countries, dealing with this challenge will be quite difficult for UK. Foreign Direct Investment in UK: EU had enormous potential. Thus it attracted huge FDI. With UK being its most stable economies, it attracted huge amount of FDI and has been the first choice of investors amongst all the countries of EU considering the FDI (House of Commons Tresury Committee, 2016). The ability of UK to attract FDI in future will reduce and such aspect will have considerable impact. The budget planning will be disturbed and can have huge impact in the long run.
