Addition reflects continued growth and innovation across the global index ecosystem 

Washington, D.C.  – May 20, 2026 – The Index Industry Association (IIA), an education and  advocacy organization representing independent index providers worldwide, today announced that  Taiwan Index Plus has joined the association as its newest member. 

Taiwan Index Plus’ addition reflects the continued expansion and evolution of the index industry,  especially in the Asia Pacific region, as different providers develop unique and innovative  benchmarks across asset classes to meet the changing needs of investors worldwide. 

“We’re thrilled to welcome Taiwan Index Plus as we continue growing our global presence,” said  Kirsten Wegner, CEO of the IIA. “Indexes help market participants understand performance, risk,  and opportunity across regions and asset classes. Taiwan Index Plus brings deep industry expertise  from a dynamic market, and its perspective will strengthen our mission to promote transparency,  education, and facilitate dialogue across the financial ecosystem.” 

Established in 2016, Taiwan Index Plus is Taiwan’s first dedicated index company and a wholly  owned subsidiary of the Taiwan Stock Exchange. The firm develops, maintains, and licenses indexes  in Taiwan and globally, and partners with international institutions to create indexes used as  benchmarks and for investment products such as ETFs, futures, and structured products. 

Sherman Lin, Chairman of Taiwan Stock Exchange Corporation (TWSE) and Taiwan Index Plus  (TIP), said, “TIP proudly marks a significant 10-year milestone this year. We have grown to become  a major index provider in the Taiwan market and gradually expanding to the international arena.  Joining the IIA will assist us in actively monitoring global index industry dynamics, increasing  opportunities for professional networking, and boosting our corporate brand visibility, thereby  providing new momentum for the development of our index business.” 

The IIA serves as a leading voice for the global index industry, working to educate investors,  policymakers and stakeholders, advocate for sound industry standards, and foster dialogue among  market participants. Its 18 members collectively administer more than three million indexes across  equities, fixed income, commodities, and other asset classes, underscoring the critical role indexes  play in modern financial markets.
