Pensions: Infl ated worth
Features Pensions
The Retail Prices Index (RPI) measure of infl ation in the UK is set to be reformed. The UK’s independent statistical authority, the Offi ce for National Statistics (ONS), views the measure as fl awed, and plans to change it from no later than 2030, reducing the RPI measure of infl ation by some 1% per year.
All users of RPI will be impacted. Unless they have off setting gains, those who have bought RPI-linked government bonds (gilts), been awarded RPI-linked payments by a court, or are in receipt of RPI-linked pensions or insurance payments will lose out.
This planned reform is already having signifi cant impacts on bond markets and on the work that actuaries do, from advising on assumptions to designing hedging strategies.
What is wrong with RPI?
Since 2010, and arguably for some time before then, the RPI measure has systematically overstated UK infl ation. This is mainly because of the use of an ‘arithmetic’ formula (technically called ‘Carli’) to calculate RPI, which has the eff ect of overstating some price increases – especially high street clothing prices. There are other weaknesses, too.
The ONS has openly discussed these fl aws for many years. It strongly discourages the use of RPI and points to more modern statistics, in particular the Consumer Prices Index (CPI) and the CPIH. The Bank of England’s infl ation target is based on the CPI, while the CPIH is a statistical cousin that incorporates housing costs. Both the CPI and the CPIH use a ‘geometric’ formula, rather than the arithmetic formula used in the RPI, and are produced using internationally agreed guidelines.
Because of the systematic biases within the RPI, infl ation measured by RPI is expected to be higher than that measured by the CPI and the CPIH by around 1% each year. That’s a really big error, particularly when accumulated over many years.
The challenge is that the RPI is still used to adjust incomes and payments throughout the economy. This is because it is written into contracts for historical reasons, which can’t easily be changed.
What is changing?
In January 2018, the then Governor of the Bank of England Mark Carney asked the House of Lords to look into this problem. A year later, the House of Lords published a report recommending changes that would lead to the use of a single infl ation measure in the long term, to be considered by government and the ONS.
In September 2019, the ONS and Treasury published their response:
INFLATED WORTH Jonathan Camfield looks at the planned RPI reforms’ potential implications for bond markets, pension schemes and actuarial work
Features Pensions
The RPI would be retained as a measure, but the underlying formula within RPI would be changed to be the CPIH formula. This change will be implemented no later than 2030, but the Treasury will consult on whether this should be brought forward to 2025.
That consultation is now underway and closes on 21 August.
Who will be impacted by the changes?
Some of the biggest consequences will be felt in pensions. According to a Lane Clark & Peacock survey, around 70% of pensions promised by occupational defi ned benefi t (DB) schemes are linked to the RPI. Millions of pensioners will therefore receive lower pension increases in the future, and this in turn will save pension schemes money.
However, DB pension schemes hold the vast majority of the RPI-linked gilt market. Schemes will therefore lose out, as the public purse will pay less interest on those gilts in the future. The net eff ect will vary signifi cantly by scheme: The majority of schemes award RPI pension increases and have only partly hedged with index-linked gilts and other
RPI assets, such as swaps. These schemes’ fi nances will improve, reducing the cost to sponsors. Some schemes award CPI pension increases but have hedged this risk with
RPI assets. These schemes’ fi nances will worsen, increasing the cost to sponsors. Pension schemes and insurance companies that have fully hedged their infl ation risks will see little net impact on their fi nancial positions.
What implications are there for actuarial advice?
Movements in the RPI-linked bond markets at the time of the announcements were relatively small, but there have been further movements since. This could mean investors think there is some uncertainty around RPI reform. If so, there could be investment opportunities to exploit if RPI reform does go ahead as planned.
In the meantime, there are a wide range of views on the likelihood and timing of RPI reform. This leads to challenges for pension scheme actuaries advising on assumptions
WILL COVID-19 HAVE AN IMPACT?
In my view, the economic crisis has made it more likely that the Treasury will decide to implement the RPI change from 2025 rather than 2030, in order to reduce public borrowing costs. If this happens, the impacts I have outlined will be even more signifi cant.
Separately, the COVID-19 crisis may well cause negative infl ation in the coming months. Most pension schemes cannot reduce pensions when infl ation goes into negative territory, but must increase pensions when prices recover. This creates a ratchet eff ect for pension increases in many schemes, which could add to scheme costs.
for the funding of pension schemes, and the reporting of pension scheme fi gures in company accounts.
In practice, I am seeing actuaries reduce the ‘wedge’ between their RPI and CPI assumptions – for example from 1% to 0.5% per year from 2030 – and keeping these assumptions under close review. In some cases, I am seeing actuaries review how they set RPI assumptions and assuming a higher ‘infl ation risk premium’. (An infl ation risk premium can be defi ned as the extent to which investors accept lower yields on index-linked bonds because of a preference for infl ation protection.) The apparent partial impact to date of the RPI change on bond markets also presents challenges when reviewing infl ation hedging strategies: Does it still make sense to hold indexlinked gilts and swaps to hedge CPI pension increases? If the market hasn’t yet fully adjusted, should a pension scheme temporarily reduce RPI hedging levels? Should a scheme tactically reduce RPI hedging across apparently expensive sections of the infl ation curve and increase RPI hedging where it appears cheaper?
In recent months, a number of schemes have worked through these challenges and changed their hedging strategies in order to make use of opportunities arising from market anomalies – and, more importantly, to ensure they remain happy with the balance of risks they’re taking.
Other important implications for pension schemes include: Changes in assumptions will lead to changes in member option terms, such as transfer values, pension increase exchange terms and commutation factors for converting pension to cash at retirement. RPI changes could trigger further reviews of the appropriate index to use for pension increases under some scheme rules. The knock-on impact on bulk annuity pricing may make insurance contracts more or less attractive to some schemes. Trustees will need to think about appropriate communications to members in due course.
What about compensation?
I haven’t yet mentioned the possibility of compensation for index-linked gilt holders and, in turn, pensioners. Many in the pension and investment world are calling for this. There are arguments for and against, as the status quo arguably isn’t fair and has already resulted in large transfers of wealth that it may not be appropriate to JONATHAN sustain.
