Treasury Bill meaning

What does Treasury Bill mean?
A Treasury bill is a short-term government debt instrument used in transactions and financings to hold or give highly liquid, low-risk exposure to the sovereign. In the UK it is issued in sterling by HM Treasury (via the UK Debt Management Office) with maturities up to 364 days; in Ireland it is issued in euro by the National Treasury Management Agency with maturities typically up to 12 months. Treasury bills (T‑bills) are zero‑coupon money market instruments sold at a discount to par and redeemed at par on maturity; the discount represents the investor’s return. They are dematerialised and transferable through recognised settlement systems, and are widely used as collateral (including under GMRA/ISDA credit support), in repo transactions and for liquidity management by banks and corporates. Usage and meaning are consistent across England & Wales, Scotland and Northern Ireland; in Ireland the term has the same ordinary meaning. “Treasury bill” is a descriptive market term used across multiple legal contexts; the legal terms of each issue are set out in the relevant issuance documentation and applicable public debt rules.

UK IFPR for MiFID investment firms: Archived implementation timeline - FCA rules, PRA policy and UK legislative measures (2020–2023)

ARCHIVED: This Practice Note has been archived and is no longer maintained. On 20 December 2017, the European Commission set out plans to reform the prudential regime for investment firms across the European Union, with the aim of delivering a framework that is more proportionate and more sensitive to risk. Those proposals ultimately resulted in the Investment Firms Regulation (EU) 2019/2033 (EU IFR) and the Investment Firms Directive (EU) 2019/2034 (EU IFD). As the EU regime only started to apply from 26 June 2021 (ie after the end of the implementation period that followed the UK’s withdrawal from the EU), it therefore did not automatically take effect in the UK. In June 2020, HM Treasury outlined, via the Financial Services Bill, its intention to legislate for an Investment Firms Prudential Regime (IFPR) that would broadly mirror the EU IFR and EU IFD while being tailored to the UK. The Financial Services Bill received Royal Assent on 29 April 2021 and became law as the Financial Services Act 2021 (FSA...
