With yields on State development loans (SDLs), also known as State government securities, hovering around 8 per cent, these securities are emerging as an attractive option for retail fixed-income investors seeking relatively higher returns. Recent Reserve Bank of India (RBI) auctions have seen 10-year SDLs fetch cut-off yields in the range of 8.10 per cent level.

These yields compare favourably with several conventional fixed-income investment avenues available to retail investors. Further, the backing of State governments provides considerable credit comfort, making SDLs worth considering for investors who prioritise capital preservation.

SDLs function much like Central government securities, but are issued by State governments to meet their financing requirements. In the event of a payment shortfall, the dues can be adjusted against funds payable by the Centre to the respective State. They are sold through RBI-conducted auctions, with maturities ranging from two to 40 years and interest paid semi-annually. The interest income is taxable at the investor’s applicable income-tax slab rate.

Background

The RBI’s 25-basis-point repo rate hike on October 7, accompanied by a change in its monetary policy stance, has altered the outlook for the fixed-income market. Expectations of further monetary tightening have put pressure on bond yields, with another 25-basis-point hike in December possible amid persistent inflationary pressures.

Venkatakrishnan Srinivasan, Bond Market Expert and Founder & Managing Partner of Rockfort Fincap LLP, explains that crude oil prices, particularly if they remain above $110 per barrel, could fuel imported inflation, weaken the rupee and push up domestic fuel prices. Weak monsoon conditions and higher food prices add to inflation concerns. If crude prices remain elevated, the 10-year government security (G-Sec) yield, currently around 7.4-7.5 per cent, could rise further. While markets have already factored in some of the risks associated with higher crude prices and possible rate hikes, sustained inflationary pressures could push yields higher.

Supply-side pressures could add to the strain. State governments are stepping up their borrowings. RBI data show that market borrowings by States and Union Territories for October-December 2026 stood at ₹3.61 lakh crore, 28 per cent higher than the ₹2.82 lakh crore scheduled for the corresponding period last year.

Meanwhile, rising yields on AAA-rated corporate bonds have made them relatively more attractive than SDLs. This could compel State governments to offer higher yields to attract investors, Srinivasan noted.

However, the outlook could change if crude prices fall sustainably below $80 per barrel or geopolitical tensions ease. Such developments could trigger a rally in the bond market and pull yields down by 30-40 basis points.

SDL yields have risen in tandem with G-Sec yields. Clearing Corporation of India data as of October 29 show five-year SDL weighted average yields at 7.9 per cent, while 10-year and 15-year yields stood at 8.18 per cent and 7.99 per cent, respectively. The weighted average spread between G-Secs and SDLs stood at 61 basis points.

What it means for investors

Recent RBI auctions have seen 10-year SDLs fetch cut-off yields of around 8.10 per cent, translating into effective annualised yields of about 8.26 per cent, given semi-annual interest payments.

At these yield levels, SDLs offer fixed-income investors an opportunity to lock into relatively-attractive returns over the long term. These yields compare favourably with bank fixed deposits, particularly those offered by large public and private sector banks, where interest rates are generally lower. Unlike bank FDs, SDL prices fluctuate with market yields, making premature exits potentially costly.

For instance, SBI offers 6.3 per cent on retail term deposits with tenures of up to five years (6.8 per cent for senior citizens), while HDFC Bank offers 6.4 per cent for a comparable tenure (6.9 per cent for senior citizens).

Even against RBI Floating Rate Savings Bonds, which currently offer 8.05 per cent for July-December 2026, SDLs provide a marginal yield advantage. Their yields are broadly comparable with the 8.2 per cent offered by the Senior Citizens Savings Scheme.

For investors with a long-term horizon who can hold the securities until maturity, SDLs can be a useful addition to a diversified fixed-income portfolio. However, with interest rates potentially rising further, investors need not commit their entire allocation immediately. Staggering purchases across auctions could help capture higher yields if they materialise. Those comfortable with current yields and willing to hold until maturity can begin building exposure.

How to invest

Retail investors can gain exposure to SDLs through multiple channels, including the RBI Retail Direct platform, banks, primary dealers, stockbrokers, BSE Direct, NSE goBID and online bond platforms. Another route is through mutual funds, particularly Target Maturity Funds (TMFs) that invest predominantly in SDLs or a combination of SDLs, G-Secs and PSU bonds.

RBI Retail Direct provides a direct and cost-effective route to invest in SDLs. Investors can participate in primary auctions through the non-competitive bidding facility, with a minimum investment of ₹10,000. The platform also facilitates purchases and sales in the secondary market. There are no charges for account opening, maintenance or bid submission.

The RBI generally conducts SDL auctions every Tuesday, with the borrowing calendar and indicative issuance schedule published periodically. However, secondary-market liquidity can be limited, making it difficult to exit before maturity at a favourable price. Investors should, therefore, approach SDLs primarily with a buy-and-hold strategy.

Online bond platforms, such as Fundzbazar, provide access to secondary-market SDLs, with details of coupon rates, maturity dates and yields to maturity (YTM).

For investors who prefer a diversified and professionally managed route, TMFs offer a convenient alternative. These passive funds have predefined maturity dates and track underlying bond indices. As per the latest data, SDL-heavy TMFs are available across maturities, with residual maturity extending up to 10.4 years. Depending on their mandates, these funds invest exclusively in SDLs or in a combination of SDLs, G-Secs and PSU bonds.

While TMFs offer visibility on the maturity profile and prevailing portfolio yields, their returns are not guaranteed. Expenses, portfolio changes and reinvestment rates can influence the final outcome, even when investors remain invested until maturity

With bond yields rising across maturities, TMFs have also become relatively attractive. For instance, the Kotak Nifty SDL Jul 2033 Index Fund had a YTM of 7.8 per cent as of October 29.

While evaluating individual SDLs, investors should also examine the fiscal position of the issuing State. Differences in revenue generation, debt levels and fiscal discipline can result in variations in yields across States. Those States with stronger fiscal profiles, such as Maharashtra, Gujarat and Tamil Nadu, generally find greater acceptance among institutional investors. Investors must also account for interest-rate risk, liquidity constraints and taxation.
