Harald Link Net Worth

Harald Link has an estimated net worth of $1.8 billion, according to Forbes Real-Time Billionaires, Harald Link profile (figures as of October 20, 2026). That is down from a peak of $3.1 billion.

Harald Link is the chairman, chief executive, and owner of B.Grimm in Bangkok. He is the third-generation head of the group, which works across energy, real estate, transport, and healthcare. The business began in 1878 as Siam Dispensary and later became part of his family after his grandfather Adolf Link acquired it in 1914. Link came to Bangkok in 1978 to join his uncle in the company and took over as chief executive in 1987.

His wealth is tied to B.Grimm’s broad business base and to the expansion of its power arm. In 2017, he led the first IPO of a group company by listing B.Grimm Power PCL on the Stock Exchange of Thailand. Forbes says B.Grimm’s power unit operates in 14 countries. Link also serves as chairman and chief executive while preparing daughter Caroline for a future leadership role at the family group.

How Harald Link makes money

Link’s fortune comes from B.Grimm, a diversified group with interests in energy, real estate, transport, and healthcare. He joined the family firm in Bangkok in 1978 after studying in Switzerland and Germany, where he grew up. Since becoming chief executive in 1987, he has overseen the company as its chairman, chief executive, and owner. That long leadership run put him at the center of the group’s business decisions and expansion.

A key money step came in 2017, when Link listed B.Grimm Power PCL in the first IPO of any B.Grimm group company. That move gave investors a public way to buy into part of the business. Forbes notes that the power unit does business in 14 countries. The wider group still spans several sectors, so his wealth is linked to both the listed power business and B.Grimm’s other holdings.

Forbes net worth history

Forbes has tracked Link’s fortune through several swings. It placed him at $2 billion in 2019, then $2.2 billion in 2020 and $3.1 billion in 2021. After that, the estimate moved down to $2.1 billion in 2022, up to $2.2 billion in 2023, and back to $2.1 billion in 2024. Those changes happened while his money stayed connected to the same diversified B.Grimm businesses.

The Forbes estimate dropped to $1.4 billion in 2025, then rose to $1.6 billion in 2026. Forbes’ real-time tracker later showed $1.8 billion as of October 20, 2026. Even with those changes, the basic picture stayed consistent: Link’s wealth comes from a long-running family group with operations across several industries, plus the listed power company that became public in 2017.
