Funding ratios of DB plans, which measure the amount of liabilities that available assets cover, have evolved differently over the years across countries, but tended to improve in most of them. Among the 12 reporting countries, 9 recorded a stronger funding ratio than a decade or so before, with the largest improvement occurring in the United Kingdom (30 percentage points more between end‑2012 and end‑2022), Ireland (20 percentage points more between end‑2015 and end‑2022) and the Netherlands (12 percentage points more between end‑2012 and end‑2022) (Figure 9.6). The funding ratio of DB plans also improved but to a lesser extent in Finland, Germany, Luxembourg, Norway, Switzerland, and the United States. By contrast, the funding ratio deteriorated in Iceland (by 29 percentage points between end‑2012 and end‑2022), Mexico (by 13 percentage points between end‑2012 and end‑2021) and Indonesia (by 6 percentage points between end‑2012 and end‑2021).
Despite a fall in the value of assets in 2022, the funding ratio of DB plans improved in 2022 in Luxembourg, the Netherlands, Norway and the United Kingdom as the liabilities of DB plans fell more than assets. The United Kingdom saw the largest improvement in the funding ratio of DB plans in 2022 (10 pp more between end‑2021 and end‑2022). By contrast, the funding ratio of DB plans worsened in jurisdictions where the liabilities remained broadly the same or slightly increased (e.g. Germany, Iceland, Finland, Switzerland and the United States).
Funding levels of DB plans were above 100% at the end of 2022 (or latest available year) in all reporting countries but four: Iceland (28%), Mexico (67%), the United States (64%) among OECD countries, and Indonesia (97%).
Funding levels are calculated using national (regulatory) valuation methodologies of liabilities and hence cannot be compared across countries. Some countries like Finland, Iceland and Luxembourg use fixed discount rates (at 3%, 3.5% and 5% respectively), while others like the Netherlands and the United Kingdom use market rates as a discount rate. In the Netherlands, pension funds can use an Ultimate Forward Rate (UFR) for the valuation of liabilities. The UFR is an extrapolation of the observable term structure to take into account the very long duration of pension liabilities. The Pension Protection Fund in the United Kingdom uses conventional and index-linked gilt yields to calculate the liabilities of the DB plans in the scope of its index (PPF 7 800). The choice of the discount rate that is used to express in today’s terms the stream of future benefit payments can have a major impact on funding levels. The recent increase in interest rates led to a decline in the value of the liabilities in countries using a market-based discount rate while it had little impact on those using a fixed discount rate.
