The Quiet Giant in Your Premium
Every PKV premium contains a savings slice that flows into your ageing reserve (Alterungsrückstellung) — and collectively those slices have grown into one of Germany\'s largest capital pools: well over €300 billion across the industry, growing yearly. This capital is not a bookkeeping abstraction; it is invested money whose returns co-finance your old-age premiums. Where it goes deserves a look.
The legal frame: ageing reserves belong to the guarantee assets (Sicherungsvermögen) — a legally segregated pool, monitored by a trustee, ring-fenced from the insurer\'s other business and protected even in insolvency. Investment rules follow the prudent person principle under Solvency II, supervised by BaFin.
How the Money Is Invested
| Asset class | Role in the portfolio |
|---|---|
| Fixed income (government/corporate bonds, Pfandbriefe) | The backbone — the majority of holdings, matched to decades-long liabilities |
| Real estate | Stable income; insurers are among Germany\'s largest property investors |
| Equities and participations | Return enhancement within risk budgets |
| Infrastructure and alternatives | Growing allocation — long-duration assets fit long-duration promises |
The portfolio\'s character follows from the liability: promises stretching fifty years ahead demand duration, security and steady income over spectacular returns.
How Returns Reach Your Premium
- The calculation interest (Rechnungszins): premiums assume the reserves earn a certain rate — the actuarial company rate is reviewed annually per tariff. Earn less than assumed for long, and premiums must rise (a driver of the low-interest decade\'s increases); earn more, and surpluses arise
- Surplus participation: by law, at least 90% of investment surpluses on the reserves must benefit policyholders — funding premium refunds, benefit stability and the cushioning of old-age premiums
- The 10% surcharge: the statutory supplement (ages 22–60) flows into extra reserves specifically deployed from 65 to damp increases
What Rising and Falling Rates Mean for You
The 2010s squeezed PKV: falling market yields dragged achievable returns below old calculation rates, forcing premium corrections across the industry. The rate normalisation since then works the other way — new money earns more, easing pressure and refilling surplus pots. Neither direction changes the architecture: your reserves remain segregated, trustee-guarded and yours in function, whatever the yield curve does.
The Bottom Line
Your ageing reserve is real capital in a legally armoured pool, invested with pension-fund conservatism, its surpluses largely mandated back to you. When comparing insurers, the net investment return on these assets — published annually — is one of the quietly meaningful figures: over half a century, half a percent of extra yield does premium work no marketing budget can match.
