In fact, the only "uncharacteristic upturn" IPPR found was for legal professionals working in financial industry, with a 21 percent rise in postings, and customer service occupations within finance, with a 34 percent rise in postings. All of the other most frequently posted occupations suffered between a 5 percent and 33 percent drop in postings.
The data comes as speculation mounts over what kind of access to EU markets will be granted to the financial sector operating in the U.K., a sector whose strength is largely thanks to it being the home of many of Europe's financial services and their headquarters.
These businesses could relocate to the continent if access to the EU (through so-called "passporting rights") are lost in the post-Brexit negotiations. Talks have yet to begin, however, and will only do so when the U.K. triggers Article 50 -expected to be sometime in 2017.
In the meantime, the IPPR's research shows that employers in the financial sector are cautious while they don't know what impact will be felt by Brexit and what the post-EU relationship will look like.
On Monday, European Central Bank (ECB) policymaker Jens Weidmann said that the U.K. would lose its much-prized "passporting" rights unless Britain was at least part of the European Economic Area (EEA). This would mean the U.K. accepting a founding principle of the EU's single market – the free movement of people - a controversial point for Brexit campaigners and one likely to be a major sticking point in the wider EU-U.K. negotiations.
