HDFC Mutual Fund has announced new restrictions on investments into its popular HDFC Defence Fund, capping fresh Systematic Investment Plans (SIPs) and Systematic Transfer Plans (STPs) at ₹25,000 per investor per month. The new framework comes into effect on May 4, 2026, as the fund house seeks to regulate the accelerated inflows into its concentrated thematic portfolio.
Understanding the New Investment Framework
Under the revised guidelines, new SIP registrations and fresh STP registrations will be limited to ₹25,000 monthly per investor. These changes specifically apply to new investments, ensuring that existing SIPs and STPs will continue without any alterations. Investors also retain full flexibility for redemptions, with no restrictions imposed on exiting the fund.
This move follows earlier measures by HDFC Mutual Fund, which included restrictions on fresh lump-sum investments and switch-ins. Such steps are typically adopted by asset management companies when a thematic or sectoral fund experiences rapid growth in assets under management (AUM), potentially leading to challenges related to liquidity, optimal fund deployment, and maintaining portfolio concentration.
HDFC Defence Fund: Performance and Focus
Launched in June 2023, the HDFC Defence Fund is an open-ended equity scheme primarily investing in companies within India's defence and allied sectors. As of March 31, 2026, the fund managed approximately ₹7,304 crore in AUM across a portfolio of 22 stocks, spanning large-cap, mid-cap, and small-cap segments.
The fund has demonstrated robust performance since its inception, delivering nearly 40% returns. Over the past year, it has gained over 27%, and more than 10% in the last three months alone. This strong performance reflects significant investor interest, driven by a growing policy focus on domestic manufacturing and indigenization within the defence sector.
Considerations for Investors
Financial planners often caution that thematic funds, such as defence-focused schemes, inherently carry higher volatility and concentration risks compared to diversified equity funds. Their performance is closely linked to specific sector cycles, government policies, and spending trends. Consequently, these funds are generally recommended for investors with a higher risk appetite, a long-term investment horizon, and a clear understanding of the sector's dynamics.
From a taxation standpoint, the HDFC Defence Fund is classified as an equity mutual fund. Long-term capital gains (on investments held for over one year) are exempt up to ₹1.25 lakh annually, with gains exceeding this threshold taxed at 12.5%. Short-term gains (on holdings under one year) are taxed at 20%. Dividends are added to an investor's income and taxed according to their applicable slab, with a 10% tax deducted at source if the annual dividend income surpasses ₹10,000.
The introduction of SIP and STP caps by HDFC Mutual Fund represents a strategic effort to manage the fund's scalability effectively while upholding investment discipline within a high-growth yet narrowly defined sector.
