Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what discussions she has had with relevant stakeholders on targets that have been set for the UK Social Investment Fund in terms of measurable outputs for each of the next three financial years.
Answered by Lucy Rigby - Economic Secretary (HM Treasury)
The Social Investment Fund was launched by M&G on 21st January and aims to invest up to £1 billion into the UK economy over the next three to five years to support new affordable homes, regeneration projects and infrastructure. This commitment aligns with the Government’s aim to encourage LGPS assets to be invested to boost UK economic growth.
The Chancellor has discussed the fund with M&G and supports their intention to align it with the government’s Missions including urban regeneration, clean energy and essential infrastructure that improves health and community wellbeing.
It is private finance and M&G will manage the fund in the best interests of investors, to deliver measurable impact across the UK.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what steps she is taking to ensure delivery of pledged additional risk capital by signatories to the Mansion House Accord.
Answered by Torsten Bell - Parliamentary Secretary (HM Treasury)
In May 2025, 17 of the largest workplace pension providers signed the Mansion House Accord and voluntarily committed to invest at least 10 per cent of their defined contribution default funds in private markets by 2030, with at least half of that invested in the UK.The organising bodies of the Accord have committed to working with government and regulators to ensure that data demonstrating progress against the Accord will be tracked.
The government has a broad programme of reform which will facilitate pensions investment across the UK. The British Business Bank has launched an investment vehicle, the British Growth Partnership (BGP), and the new Venture Link initiative, to help pension funds invest more in UK venture opportunities. The Sterling 20 partnership was also established last year. The investor-led partnership between 20 of the UK’s largest pension funds and insurers is working with the government and the City of London Corporation to help ensure pension schemes have visibility of the range of investment opportunities in productive assets.
The government is also legislating in the Pension Schemes Bill for a reserve investment power, to act as a backstop to the Accord.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what analysis her Department has undertaken on the potential fiscal implications for future public spending decisions of altering the declining discount rate regime.
Answered by James Murray - Chief Secretary to the Treasury
The independent review of the Green Book discount rate will be published in the summer 2026.
Changes to the Green Book discount rate methodology will affect the appraisal of major infrastructure projects that involve benefits and costs well into the future.
The discount rate review will inform the government’s decisions on major projects at the next Spending Review. It will help to ensure that the government makes fair assessments of transformational projects that provide long-term benefits.
HM Treasury’s terms of reference for the discount rate review note that the lead authors should look at international comparisons to better inform their judgements on the UK approach.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what assessment she has made of the data-gathering requirements needed to support future green bond issuances.
Answered by Lucy Rigby - Economic Secretary (HM Treasury)
In 2024-25, the government raised £10.0 billion through green gilts and green savings bonds. The government plans to issue a total of £10.0 billion of green finance in 2025-26, subject to demand and market conditions. The amount of Green Financing to be issued in each financial year will be announced by HM Treasury as part of the annual government financing remit.
The Green Financing Framework, published in 2021 and updated in 2025, explains how proceeds from green gilts and NS&I’s retail Green Savings Bonds will finance public expenditures that demonstrate a direct and positive environmental impact.
The Framework includes guidelines on the types of expenditures that can be included in the Programme and commits the government to annual allocation reporting. Eligible expenditures are drawn from departments’ confirmed Spending Review settlements and assessed on the basis of their contribution to the government’s climate and environmental objectives. Details of the allocation of expenditure are normally published each year in the Green Financing Allocation Report, most recently published in October2024.

Question to the HM Treasury:
To ask the Chancellor of the Exchequer, what assessment her Department has made of the potential impact of limiting interest-earning reserves on the commercial viability of pound-backed stablecoins.
Answered by Lucy Rigby - Economic Secretary (HM Treasury)
The government is committed to making the UK a global hub for digital assets. It recognises the huge potential posed by tokenised asset innovation, and for stablecoins to support innovation in both retail payments and wholesale settlement.
That is why the government is bringing in legislation to establish a new financial services regulatory regime for cryptoassets, including stablecoin, and maintaining a close and ongoing dialogue with the financial regulators as they develop detailed rules and guidance.
This legislation complements other measures being taken forward by the government on digital assets, including: the Digital Securities Sandbox, which supports settlement using distributed ledger technology; the Digital Gilt Instrument pilot issuance; and the publication of the Wholesale Financial Markets Digital Strategy.
