In this video, we will explain in detail what is Securities Transaction Tax (STT) and how the changes made in it after Budget 2026 will affect traders and investors. The increase in trading costs due to STT hike may have a direct impact on short-term traders, especially F&O participants, which may reduce the profitability of intraday trading and high-frequency trades. There may also be a slight impact on short-term pressure in volumes and market liquidity. There may also be some indirect effects for retail investors and mutual fund investors. In this video you will get complete breakdown of STT changes in simple language, practical examples and also how to adjust the trading strategy further.
