Corium Treasury

Welcome to Corium Treasury Limited, founded by James Leather in 2018, as a provider of interim and advisory corporate treasury services. Drawing on the extensive experience of James and a global network of professionals, Corium helps businesses to identify their financial risks, to formulate appropriate responses and to ultimately, successfully navigate these risks.

Recent assignments include: project lead for a £5.5bn LIBOR liability management exercise on behalf of Landsec Plc; liquidity and funding support for a distressed international outsourcing & construction company; writing a Liquidity & Investment Management review for a FTSE 250 growing international software company; writing an FX policy for a private equity owned, global freight terminal operator and interim Global Director of Treasury for a highly leveraged, multi-national IT services company.

James is a corporate treasurer with 20 years’ cross-sector experience operating from London and Sydney, into Asia, Europe, the Middle East and Africa. He is a former member of the UK’s Working Group on Sterling Risk-Free Reference Rates and a technical contributor to the Association of Corporate Treasurers.


What we do and how we do it

Service 1: IBOR Transition

“Bigger than the EURO” is how some have described the end of LIBOR – but it doesn’t have to be overwhelming. A combination of planning, cross-functional engagement, training and execution can make the challenge manageable.

Corium Treasury can provide project management or advisory services to help your organisation transition in time.

Service 2: Liquidity and Investment Review

How much liquidity do we need? Which instruments can we use? Do we have surplus liquidity? How should this be invested – and how should it be managed?

Corium Treasury can help untangle governance from policy and processes from systems, by analysing where your organisation stands today on this fundamental subject and setting out options for the future, in a structured report.

Service 3: FX Risk Review and Policy Creation

Understanding the exact FX exposures an organization faces can be tricky. But getting this understanding is vital if they are to be effectively managed.

Corium Treasury can help a business gain this understanding, as well as assess how any FX exposures can be managed, before converting this information into a policy, with system and process recommendations.

Service 4: Training

There are times when training can help – be it for a specific need, such as compounding (e.g. SONIA, SOFR etc) and ESG, or for a general requirement, such as accelerating the skills of a new team member, so that they can contribute to the team, more quickly than might otherwise be possible.

Corium Treasury can provide both specialist and general training, as required.

Service 5: Presentational Performance

Heart pounding like a bass drum?

Corium Treasury has teamed up with performance researchers from the Royal College of Music and Imperial College to harness techniques such as Virtual Reality and sequential simulation to improve high-pressure presentational performance. Treasurers are not always natural presenters and can benefit from some coaching, to help with critical presentations, such as to the board, to debt investors, to the CFO, or to the CEO – or even to their own team.

Service 6: Interim Services

Sometimes, the services of an interim can be helpful: for some, it buys time, so a permanent replacement can be chosen without rushing; and for others, the expertise that a contractor brings is attractive, as they are able to ‘hit the ground running’ and immediately add value in troubling times, deploying a range of skills from implementing cashflow forecasting models, to handling LIBOR transition.

Whatever your interim need, Corium Treasury can probably help you fill the gap and leave your organisation with lasting improvements.



James is a qualified accountant (CGMA), a qualified bank treasurer (ALMA) and a qualified corporate treasurer (FCT).
