Simon Jaquiss

Financial Market Consultant


Simon Jaquiss started work in the City of London in 1984, having earned a degree in Economics with Economic History and then spent the period from 1984 to 2006 working for a series of investment banks trading derivatives based on interest rates and foreign exchange.

This included spells in Hong Kong, with Citibank, as Vice-President and banks such as BZW, Paribas, Rabobank, and Investec.

At Rabobank and Investec Simon became increasingly involved in treasury management, that was, running the liquidity and hedging activities of branches of those banks and between 2007 and 2011 he acted as treasury for two banks in the Middle East.

In 2011 upon returning to London, Simon spent a year and a half working at PwC as part of its Risk Advisory Group, providing consultancy services to some of the UK’s largest Wholesale Banks.

From 2012 onwards, having spent nearly 30 years in dealing rooms, Simon set up a business as a banking consultant, initially becoming involved with holding banks to task for mis-selling of complex financial products, and then helping clients gain redress and compensation.

He then began to provide forensic reports, derivatives calculations and valuations to the legal profession and assisting banks in their claims. Since 2013 his activity has included Expert Witness work, and providing training and regulatory guidance to lawyers, accountants, banks and regulators.


  • "An exceptional communicator"

    I have known and worked closely with Simon for over ten years in banking and related cases. His expertise is second to none and is rooted in his day to day experience at the heart of the industry. His expert reports are concise and models of clarity and always contribute to an understanding of the issues.

    He is an exceptional communicator particularly with clients. He can make the most complex issues comprehensible to lawyers and clients alike while his own understanding of the law and regulatory environment is extremely helpful in organising case material.

    I would unhesitatingly recommend Simon to any solicitor or client seeking genuinely enlightening advice.

  • "It was a pleasure to collaborate"

    I found Simon’s considerable banking experience and expertise immensely helpful. His ability to identify and appraise the merit of potential claims concerning a complicated financial product helped funders immediately identify the key issues. It was a pleasure to collaborate.

  • "Using Simon’s services was one of the best decisions we have made."

    Simon was referred to me and after going through the loan details explained how the loan had been mis-sold. The process and timescales were explained very clearly and the probability of a successful outcome explained. After handing over the original loan agreement everything else was taken care off and a successful outcome was achieved within the timescales outlined. Thanks to the payout we are opening a new bar later in the summer. Using Simon’s services was one of the best decisions we have made.
