The exit of the United Kingdom from the European Union, unless otherwise agreed with the EU, will entail the non-application of European treaties. However, this would not have immediately detrimental effects with respect to loan agreements already entered into, which are now governed by English law and would therefore continue to be fully valid and effective.
It is not believed that the non-applicability of Community legislation may be invoked by a party to trigger a change of law clause, nor to invoke the occurrence of a relevant adverse change in order to: (i) reneging on contractual obligations; or (ii) claim termination of the contract.
In the long term we will have to wait the outcome of negotiations with the European Union to understand how the UK intends to define relations with other EU countries, especially if the United Kingdom will seek to remain within the European Free Trade Association (EFTA) together with Norway, Iceland, Liechtenstein and Switzerland, so as to continue to operate within the European Economic Area (EEA).
A negative impact of Brexit might be the decrease of economic resources for funding of community projects by the European Investment Bank (EIB).
In fact, the United Kingdom was, after Germany and France, the third largest European contributor having paid – between 2000 and 2014 – approximately 186.5 billion euro to the European budget, of which, after administrative costs, approximately 102.6 billion euro was returned from Brussels, resulting in a total balance of 83.9 billion euro, equal to 5.5 billion euro for each year.
It is easy to see that a significant amount of financial resources will be removed from the European budget, and this will lead to a lower availability of resources for funding projects through the EIB. Following Brexit, in the short term, significant adverse effects on projects and loan agreements are not expected and it will be necessary to wait until negotiations with the European Union have begun in order to develop an understanding of the long-term effects of Brexit.
With respect to the availability of financial resources, the UK’s exit could have a negative effect in terms of reduced availability of financial resources to be allocated to European funding.
