Summary

Fathom started to advise the London Borough of Newham Pension Scheme, our first local government pension scheme (LGPS) client, in May 2010 at a time when many open, defined-benefit schemes were facing material deficits, after a long period of declining interest rates had raised scheme liabilities by more than it had raised scheme assets. Newham’s funding was then at 70%. We conducted periodic reviews of Newham’s strategic asset allocation, drawing on Fathom’s proprietary model of a defined-benefit scheme to explore possible strategies under different scenarios. We briefed the investment committee face-to-face, providing in-depth analysis on how changes in the macroeconomy and financial markets would affect the funding outlook. We also offered an on-call service to give ad hoc advice whenever needed; and we supplied member training. We helped the scheme to rebalance away from a focus on UK equities, and more recently to navigate substantial interest rate changes. In 2022, at the most recent triennial review, the Newham scheme was no longer in deficit.

Our approach

Fathom applies the same rigorous, proven process to every piece of work; this process is the DNA that makes up our world-leading research.

We were approached by the investment adviser to the London Borough of Newham (LBN) Pension Scheme in early 2010 at a difficult period, not just for Newham, but for all local government pension schemes. In common with any open, defined-benefit scheme, Newham was exposed to interest rate risk. By early 2010, a long period of declining real rates of interest had raised scheme liabilities by more than it had raised scheme assets, leaving them with a material deficit. The investment adviser, already a client of Fathom, believed that Newham would benefit from a greater understanding of macroeconomic and financial market developments, and how these might affect the funding outlook. We met the then Chair of the scheme to discuss how we might help them. This resulted in Fathom being appointed macroeconomic advisers to the LBN Pension Scheme in May 2010.

Our brief was to support the scheme’s objectives by ensuring that its officers and its elected members were informed of macroeconomic and financial market developments that had the potential materially to affect scheme funding. To meet this objective, we provided a range of services, including regular briefing at face-to-face meetings of the scheme’s investment committee, periodic in-depth analysis of major events that might have a bearing on scheme funding, and member training. With committee members drawn from different backgrounds, it was important to translate complex ideas in a way that would be meaningful to the intelligent lay person. We also reviewed Newham’s strategic asset allocation several times.

An important part of our role was to be available, whether at the end of a phone line or more recently through Teams or Zoom, to provide advice to officers of the scheme when required. We had to be able to react, at short notice, to macroeconomic and financial market developments as they occurred.

Strategic asset allocation reviews

In the early stages of our relationship with Newham we conducted several strategic asset allocation reviews. With the scheme around 70% funded when Fathom was appointed, there was a clear focus on ensuring that assets were invested as efficiently as possible, maximising expected returns while ensuring that risk levels remained tolerable. As part of these reviews, we would draw on our proprietary model of a defined-benefit pension scheme (FIRM-DB) to illustrate how a range of alternative asset allocations might affect the outlook for scheme funding, not just in terms of a central case, but also the risks around that.

Changes to asset allocation strategies

One of our early recommendations was to reduce the allocation to UK equities, which reflected a third of the scheme’s equity holdings at the time Fathom was appointed, and increase the allocation to overseas equities, and to US equities in particular. Supported by the scheme’s investment adviser, this recommendation was accepted, and Newham’s overseas equity holdings began to rise. This gave the scheme a greater exposure to movements in the value of sterling, and the appropriate level of foreign currency hedging was a frequent topic of conversation. With the dollar tending to rise against sterling at times of economic stress, when equities were doing badly, our recommendation back then was that some US dollar exposure was desirable, and hedging of US dollar assets should generally be less than the hedging of other foreign currency assets. But as President Trump’s second term got under way the dollar’s attractiveness as a safe haven began to come under question, and hedging strategies started to be re-examined.

The increasing importance of interest rates

The ten years that followed the Global Financial Crisis of 2008/09, although a difficult one for the LGPS, was nevertheless one of relative economic stability. Inflation fluctuated around the 2% target, Bank Rate was stuck at or close to the zero lower bound, and long-term interest rates drifted steadily down year after year. Economic forecasting appeared straightforward. All of this changed with the COVID-19 pandemic, and the policy response to that, which saw the UK experience double-digit inflation for the first time in decades. A sound understanding, not just of macroeconomics in the round, but of monetary and fiscal policy in particular, was paramount. But as the 2020s progressed there was a growing focus on the outlook for interest rate, both short-term and long-term. This affected not just scheme assets and scheme liabilities, but with many of the officers also involved in treasury management, it was an important factor when thinking about the timing, and the duration of borrowing.

Delivery

Fathom attended quarterly meetings of the investment committee, in person at the Town Hall before March 2020, virtually during the pandemic, and a mixture of the two from 2021 onwards. We would present our views, and where appropriate our recommendations, to the elected members, the officers, the investment adviser and other stakeholders, typically using a set of slides shared in advance. Meetings with officers were held on an ad hoc basis as required between the quarterly meetings of the investment committee.

Key calls

We were often called on to provide ad-hoc advice at moments of heightened uncertainty. For example, before the June 2016 Brexit referendum we advised that the UK’s large current account deficit limited any upside to the currency if ‘Remain’ won, leaving the scheme facing a one-way bet. Following our advice, the scheme strengthened its US dollar currency hedge — and gained £20 million after the vote.

Except in cases where the scheme was planning to reallocate a portion of its assets, which brought market timing issues to the fore, as a long-term investor the client was focused on macroeconomic and financial market developments that had the potential to shape the outlook for years to come. Most of our key calls, for both the LBN and other LGPS clients, were made with this long-term perspective in mind. A selection of these appears below:

6 December 2021

“There is a risk that the pick-up in inflation will be persistent, not transitory. A material increase in interest rates of several hundred basis points will then be required.”
Bank Rate was then 0.10%. It peaked at 5.25% two years later.

17 December 2024

“We are in a ‘higher-for-longer’ world. Long-term funding costs will not be returning to pre-pandemic lows.”
By early September 2025, 30-year gilt yields had hit a 27-year high, rising more than 60 basis points since Fathom’s advice.

11 April 2025

“As long-term investors, local government pension schemes should not rush to sell their US equity holdings in the wake of President Trump’s announcement of reciprocal tariffs.”
By late summer 2025, the S&P 500 had rallied by more than 20%.
