Treasury Announces Upcoming Legal Changes for Building Societies
Nationwide Building Society customers and millions of members across the mutual sector should prepare for significant legal changes set to unfold this year. The Treasury is advancing a multi-year programme aimed at reforming the building societies sector, with fresh legislation to be presented to MPs in the coming months.
Committee Discussions on Mutual Sector Reforms
Top officials from the Treasury recently addressed the Treasury Committee, outlining plans for new legislation. This follows broader discussions about reforms designed to open up the banking sector and strengthen mutuals and co-operatives. Gwyneth Nurse, director general of financial services at the Treasury, informed MPs that a "multi-year programme" is underway to introduce changes across the mutuals sector, where organisations are owned by members rather than shareholders.
Chancellor Rachel Reeves announced a package of reforms in her 2024 Mansion House speech, including legal changes to relax restrictions on building societies regarding how they finance their activities. An amendment to the Building Societies Act 1986 has already been made, enabling the Treasury to introduce further regulation via statutory instruments to specify which types of funding can be exempted from funding limits.
Timeline for Statutory Instruments
Ms Nurse indicated that more work on this is imminent, stating, "We have not made progress on that yet, but I can tell you that we will be laying those statutory instruments before the summer recess." Parliament is due to break for summer recess on July 16, 2026, meaning these instruments will be introduced in the first half of the year. She added that additional resources have been allocated to facilitate this process.
Impact on Nationwide and Capital Requirements
Nationwide Building Society, which operates over 600 branches and serves millions of members, was specifically mentioned in previous Treasury Committee meetings. Discussions have focused on easing restrictions on bank service providers and reforming capital requirements for lenders like Nationwide.
Sarah Harrison, chief executive of the Building Societies Association, highlighted that current capital requirements, including the leverage ratio buffer, may force building societies to hold more capital than necessary for their risk portfolios. She explained, "In practice, what that means is some of the obligation on some of our building society members is to hold a lot more capital than is necessarily reflective of their risk portfolio."
According to Harrison, Nationwide has estimated that without the buffer, the organisation could potentially release an additional £30 billion in capital towards business or mortgage lending. This could significantly boost lending activity, supporting both individuals and small to medium-sized enterprises (SMEs).
Industry Response and Growth Potential
A spokesperson for Nationwide commented on the potential reforms, stating, "Reducing leverage buffers would support additional lending to both individuals, via mortgage lending, and SMEs, through business loans. With the Government's ambition to double the size of the mutuals sector, leverage ratio reform would support the sector's growth potential, where current leverage requirements can often constrain further lending activity for lower risk providers."
The purpose of these capital restrictions is to ensure lenders maintain adequate funds in reserve to sustain operations if investments or loan repayments fail. However, reforms could unlock substantial resources for the economy, aligning with broader governmental goals to enhance the mutual sector's role in the financial landscape.
As the Treasury moves forward with its legislative agenda, building society members and stakeholders should stay informed about these developments, which promise to reshape funding and lending practices in the UK.
