Primary market meaning

To gauge concentration within a particular market, competition authorities often turn to the Herfindahl‑Hirschman Index (HHI) as a primary tool that supports and streamlines their assessment. Although the absolute HHI level provides an early signal of post‑merger competitive pressure, the movement in the HHI (the ‘delta’) functions as a practical proxy for the change in concentration directly attributable to the merger itself and its immediate effects. How to calculate the HHI The HHI is obtained by adding the squares of the individual market shares of all firms participating in the market, without omitting any active competitor...

STOP PRESS: The UK’s prospectus framework still derives from the EU Prospectus Regulation, preserved in domestic law after Brexit as the UK Prospectus Regulation. As part of wider reforms to the UK capital markets and to strengthen the UK’s appeal as a listing venue, this regime has been under review. As a result, the UK Prospectus Regulation will be superseded by the Public Offers and Admission to Trading Regulations 2024 (the POATRs), with the detailed admission-to-trading requirements to be set out in the Financial Conduct Authority (FCA) admission rules. The FCA issued its final rules (PS25/9) on 15 July 2025, and they will apply from 19 January 2026. On 17 October 2025, the FCA published Primary Market Bulletin 58 which, among other points, gives guidance on the timing and approval of prospectuses (and supplementary prospectuses), and confirms the removal of Listing Particulars as an admission document, within the new framework. For further information on the key elements of the new POATRs framework relevant to the debt capital markets, see:...

The most common reasons for entering into derivatives are for the purposes of: Speculation — when a party seeks exposure to a given variable, for example taking a view on a commodity’s future price on the assumption it will rise or fall over a chosen period Hedging — aiming to offset exposure to the risk of an unfavourable shift in a variable, or to stabilise expected outcomes over time Arbitrage — seeking to take advantage of price discrepancies (between markets, or within the same market over time) to earn profit or cut costs, or where one participant can reach a price or market unavailable to another, including where prices differ over time Exposure to asset classes — obtaining access to a target market (eg commodities, shares, property) without incurring the expense, complexity and formalities associated with those markets, avoiding the same costs and complications Derivatives are commonly used alongside lending arrangements for hedging purposes in practice. In this context, the primary...
