For much of the 1980s and 1990s, UK equity valuations closely mirrored yields on index-linked gilts, government bonds adjusted for inflation. This relationship, however, broke down during the early 2000s bear market and remained disrupted for nearly two decades before beginning to re-establish itself recently.

Historically, both equities and index-linked gilts offered investors a hedge against inflation but in different forms. Index-linked gilts adjust both principal and coupons according to the Retail Prices Index, while equity dividends tend to grow in line with nominal corporate revenues. As a result, their yields typically moved in tandem: when real yields on gilts rose, equity valuations tended to fall, and vice versa.

This dynamic shifted from 2001 onward. During this period, real yields on index-linked gilts fell sharply, reaching below zero by 2012 and nearly negative 3 percent by 2021, largely due to extensive central bank bond-buying programs—quantitative easing—that suppressed yields worldwide. At the same time, equity dividend yields increased, especially during market selloffs such as the 2007-09 financial crisis and the 2020 pandemic-induced downturn. Between 2001 and 2021, equities carried an average yield premium of 3.3 percentage points over indexed bonds.

Several factors contributed to this divergence. The stock market rout and falling bond yields deeply affected UK defined benefit pension funds, which faced mounting deficits as their liabilities rose faster than assets. New accounting rules encouraged trustees to more closely match assets against liabilities, prompting widespread adoption of liability-driven investment (LDI) strategies. This led to a significant shift in pension fund allocations: from holding about half their assets in UK equities in 1999 to less than 1 percent by 2025, with a parallel increase in holdings of index-linked gilts, which reached 31 percent of their portfolios.

This reallocation fueled further shifts in UK capital markets. The erosion of demand for equities contributed to companies issuing debt to repurchase shares and engaging in leveraged buyouts, shrinking the free float of listed companies. Meanwhile, the gilt market remained much smaller by comparison, resulting in liquidity and valuation distortions.

The trend began to reverse in 2022 amid rising interest rates and the unwinding of quantitative easing by central banks. UK government bonds saw a steep selloff following the September mini-budget, which unsettled markets and triggered losses in leveraged LDI positions. Real yields on index-linked gilts moved back into positive territory for the first time in a decade, climbing to around 3.25 percent for 15-year maturities, approaching the roughly 3.0 percent dividend yield on the FTSE 100.

This shift narrows the valuation gap between equities and government inflation-linked bonds and reduces the financial incentives to continue “de-equitisation.” Analysts note that the UK equity risk premium—the excess return expected from equities over risk-free assets—is beginning to normalize.

The legacy of this transition is significant for individual investors, particularly those nearing retirement. Many who have long relied on equities to grow their wealth may now find it advantageous to sell shares at relatively high valuations and purchase government-backed real-return assets to secure predictable, inflation-protected income streams. Similar dynamics are evident in the United States, where 10-year Treasury Inflation-Protected Securities currently offer real yields near 2.9 percent, compared with a 1.1 percent dividend yield on the S&P 500.

While the strategy of shifting from equities to inflation-linked bonds on a liability-driven basis was historically cost-prohibitive, current market conditions have altered that calculus. Financial advisors emphasize that individual circumstances vary and professional guidance is essential for those considering such changes. Nonetheless, the evolving environment presents new opportunities for investors seeking to align their portfolios with long-term spending needs.
