Straits Times Index in Focus: How Singapore's Main Stock Benchmark Works

Published 2026-10-25

The Straits Times Index, known as the STI, is the main stock market benchmark for Singapore. It follows the performance of the largest companies listed on the Singapore Exchange (SGX). Many people in Singapore use the STI to understand how the local stock market is doing, and it is also used by investors around the world who want to follow Singapore's economy.

The STI is made up of 30 companies. These companies come from different sectors, such as banking, real estate, telecommunications and transport. Because the index includes many large firms, its movements can reflect broader trends in the Singapore economy. When the index rises, it usually means that the share prices of these major companies have increased overall. When it falls, it means that prices have generally dropped.

The source article used for this report is an online page that offers charts, historical data and news related to the STI. However, it did not include any current figures, price changes or specific news events at the time it was reviewed. For this reason, this article cannot report on today's movements or recent developments in the index.

Readers who want up-to-date information about the STI can check the SGX website or trusted financial news services. Anyone thinking about investing should also consider their own financial situation and, if necessary, seek advice from a licensed financial adviser.
