A report released on Thursday by TheCityUK, which represents the financial services industry, calls for a "clear and upfront" transitional arrangement to deliver continuity in the financial sector.
A transitional deal
A transitional deal would see a bridging period between the time the UK exits the EU and the time it arranges a formal trading partnership with the EU.
The financial services industry, most associated with the City of London, is a vital part of the UK economy, and accounts for 9.6% of national economic output. The sector is keen for a transitional deal as it would help avoid "damaging cliff-edge effects," according to the report.
On Wednesday, Bank of England governor Mark Carney reiterated to MPs his desire for a transitional arrangement, telling the Treasury Select Committee that "a transition phase is the best mitigant to [the Brexit] risk, it's highly advisable. If there is not such a transition put in place, there will be consequences."
Prime Minister Theresa May appears to be flip-flopping on the issue, but even the most hardline members of her cabinet - including Brexit minister David Davis - appear to be edging towards an agreement that a transitional arrangement may be necessary.
Access to EU talent
The report also says the UK needs access to EU talent to retain its status as a provider of low-cost capital to Europe.
It says: "To retain its status as the leading global financial centre, the UK needs continued access to the best talent: home-grown, from across the EU, and from the rest of the world. This is also critical to the UK's future strength as a successful exporter and provider of low-cost capital to Europe."
The government's looks set to take a hardline approach on EU immigration after Brexit. On Wednesday, Home Office minister Robert Goodwill said that the government that an "immigration skills levy" currently applied to skilled non-EU workers could apply to EU residents after Brexit.
In its current form, the levy would cost employers £1,000 per year to bring a single EU worker to the UK, which Goodwill said would "be helpful to British workers who feel they are overlooked."
