Hedging operations: own the operational management of FX and interest‑rate derivatives, including execution, confirmation, settlement, records of hedges and maturities, collateral and threshold monitoring, and treasury inputs into valuation, accounting and reporting.

Banking and facilities: act as principal treasury relationship owner for cash‑management and transaction banks, maintain the Group’s banking architecture (accounts, mandates, signatories, access, KYC and documentation), own treasury‑related facilities, and support complex funds flows for acquisitions, disposals, financings, refinancings and project financial close.

Controls, policy and governance: own treasury policies, procedures, delegated authorities and the control framework, ensure transactions are authorised, documented, reconciled and auditable, monitor compliance with policy and counterparty limits, and report to senior management and governance forums.

Systems and transformation: define the future treasury operating model, lead Treasury’s contribution to the Group’s ERP implementation, drive automation of cash visibility, forecasting, payments and bank‑statement collection, and assess the role and timing of a dedicated Treasury Management System.
