South Africa’s HNW and UHNW Families: Wealth Transfer, Hard Currency and the Strategic Role of Mauritius

South Africa remains one of Africa’s most important wealth centres. It has the deepest pool of high‑net‑worth (HNW) and ultra‑high‑net‑worth (UHNW) individuals on the continent, built over generations through entrepreneurship, mining, finance, agriculture, technology and global trade.

Yet today, South African wealth is at an inflexion point.

A powerful combination of intergenerational wealth transfer, currency risk, global mobility and structuring complexity is reshaping how affluent families think about preserving, growing and ultimately passing on their wealth. At the centre of this evolution sits a familiar but increasingly strategic jurisdiction: Mauritius.

The great South Africa wealth transfer

South Africa is entering its own version of the global “great wealth transfer”. Many of the country’s HNW and UHNW families were created in the 1970s, 80s and 90s. Founders are ageing, and second‑ and third‑generation family members are stepping into decision‑making roles.

This generational shift is driving: 

• Earlier and more deliberate succession planning

• Increased use of trusts, family investment companies and foundations 

• Greater focus on family governance 

• A move from domestic concentration to global diversification

This is not simply about inheritance. It is about resilience, control and continuity.

From rand exposure to hard-currency anchors

One of the most consistent themes among South African HNW and UHNW families is the intentional reduction of rand concentration. While many families retain operating businesses and property in South Africa, long‑term family capital is increasingly anchored in hard currency.

Affluent South Africans are: 

• Holding USD, GBP and EUR‑denominated portfolios

• Using offshore investment bonds and platforms 

• Structuring international property ownership 

• Ring‑fencing family capital offshore for succession planning

Hard‑currency exposure is no longer an offshore strategy. It is core risk management.

Why Mauritius has become central

Mauritius has evolved into a credible, well‑regulated international financial hub ideally suited to South African families.

Key attractions include:

• Legal and regulatory systems aligned with English‑law principles 

• Extensive double taxation treaties, including with South Africa 

• No capital gains tax, inheritance tax or estate duty 

• Global acceptance by banks, insurers and asset managers

Mauritius acts as a neutral coordination centre, enabling efficient asset holding, succession planning and global investment access.

The role of the modern global wealth manager

South African HNW and UHNW families increasingly want integrated advice. They are moving away from fragmented advisory relationships toward a single, globally capable wealth manager who understands their full financial and family landscape.

Why Holborn is uniquely positioned

Holborn combines deep South African heritage with international reach. With a permanent, fully staffed advisory presence in Mauritius, alongside regulated offices in major global financial centres, Holborn is uniquely placed to support South African families.

Holborn offers: 

• Cross‑border advisory expertise 

• Direct Mauritius structuring and banking relationships 

• Succession‑first, family‑governance‑led planning 

• Hard‑currency‑focused asset strategies 

• Transparent, regulated advice across jurisdictions

Looking ahead

South African HNW and UHNW wealth is not disappearing — it is repositioning. Families that succeed will be those who adopt global thinking, robust structures and trusted advisers capable of navigating generational and geographic complexity.

For many families, the question is no longer whether to think globally — but who to trust to guide them.
