Corporate Treasury

Being prepared for changes impacting the treasury environment

In today’s ever-changing and challenging business environment, corporate treasurers in particular play a pivotal role in managing financial risk and advising on business strategy decisions. Our clients increasingly face foreign exchange issues, commodity and liquidity risk in volatile and competitive markets. They are also impacted by regulatory changes as well as an increasingly automated treasury environment delivering efficiencies with new technology.

Our corporate treasury team consists of a subject matter experts who use their deep financial instrument experience to serve a broad range of corporate clients across every industry sector. We support the treasurer and the CFO, advising on accounting, valuations, governance and controls for financial instruments in a corporate setting.

Our support ranges from providing accounting advice on challenging and complex treasury transactions, assisting in developing practical solutions for the application of hedge accounting and derivative valuations and supporting the treasure and CFO by providing independent advice and assurance over all aspects of their control environment throughout the treasury lifecycle.

Risk management, strategy and operations

We help treasurers identify and quantify their exposure to financial risks, determine appropriate risk management strategies and policies, and help quantify the economic implications of specific treasury transactions. We also help the treasury function itself run more efficiently.

Governance and controls

We provide specialist independent advice and assurance over all aspects of the control environment for the treasury function. This includes: controls assurance, controls framework review, controls monitoring and MI, end-to-end process and controls review, and controls benchmarking. Additionally, we provide treasury specialist support on internal audits.

Treasury Accounting

Providing practical accounting solutions from assessment to implementation including transaction support, accounting & valuations, implementation of new standards and treasury accounting outsourcing. We cover debt issuances or restructures, derivative restructures, hedge accounting and FX accounting. We prepare management position papers, provide accounting opinions, and offer support.


We assist with determining appropriate valuation methodologies for financial instruments, performing valuations as part of a managed service and working with A&AM to develop models to perform valuations.


As technological change continues unabated, optimising efficiency and control in the treasury function through automation is key. Deloitte helps businesses rationalise their digital platforms to ensure their treasury technology is 'future-proofed'. We also work with modelling specialists to deliver bespoke solutions for risk identification, derivative valuations and hedge accounting.

Bespoke support

Includes treasury specialist secondments to non-audit clients, training on accounting matters, tax advisory support and provision of market insights impacting treasury functions, e.g. IBOR reform, ESG & Sustainable Finance.

Our Corporate Treasury Assurance team comprises audit and advisory specialists, including qualified Treasurers, Chartered Accountants, ACT Associates and Members, as well as CFA Charterholders and Treasury Consultants. They each have extensive experience researching the implications of accounting changes, and advising and assisting Corporate Treasury clients with impact analysis, accounting reviews and hedging strategies.
