The 2026 seasonal portfolio is built like an insurance programme.
ByAbhii DabasIn short
The lifestyle purchase professionalised in 2026. Wealthy families increasingly run a seasonal system of homes rather than owning one holiday house, the pattern Henley & Partners calls the sovereign portfolio, and climate resilience has joined schools and tax on the screening list. The Notre Dame Global Adaptation Initiative (ND-GAIN) index puts Norway, Finland, Switzerland, Denmark, and Singapore at the top for climate resilience, and Henley’s 180-country ranking, which blends ND-GAIN with GDP, adds the large developed economies. With around 22% of the world’s 713,626 UHNWIs buying prime property this year, a growing share of that capital is being placed against seasons and climate, not just cities. Capital at risk.
Key takeaways
- The lifestyle buyer runs a system, not a house. Summer base, winter base, and a work hub, rebalanced like a portfolio, which is the sovereign portfolio pattern Henley & Partners describes.
- Climate resilience is now a screening criterion. ND-GAIN ranks Norway, Finland, Switzerland, Denmark, and Singapore as the most climate-resilient countries, and Henley’s ranking of 180 countries blends that data with GDP.
- Resilience and lifestyle overlap more than expected. Switzerland and Singapore sit near the top of the climate, safety, and business tables at once, which is why both stay permanently expensive.
- Seasonality has a cost line. Empty months carry service charges, insurance, and in some markets vacancy rules; the second home’s true yield is net of its empty season.
- Exposure is priced in slowly. Insurance markets reprice climate risk faster than property markets do; the gap between the two is where lifestyle buyers get caught.
