PPF interest rate unchanged for 25 quarters: Can it change in October-December 2026? Key things to know

The scheme's interest rate was last changed in April 2020, when it was cut from 7.9% to 7.1% at the height of the pandemic. A status quo on Wednesday, September 30, would also extend the broader small savings freeze to a 10th straight quarter. Yet the September review would be keenly watched than the previous nine quarters amid rising India 10-year G-sec yield.

How the PPF rate is supposed to be set

Since February 2016, small savings rates are reset every quarter based on the recommendation of the Shyamala Gopinath Committee. It proposed in 2011 that each small savings scheme be benchmarked to the average secondary-market yield on a government security of matching maturity, plus a spread. For the PPF, which is a 15-year product, the benchmark is the 10-year G-sec with a spread of 25 basis points.

The quarter that is about to end will be the reference period for Wednesday's notification, and it was anything but quiet. The 10-year G-sec yield hovered around 6.7-6.9% through the first half of 2026, then broke out in September. The benchmark 6.94% 2036 bond was quoted around 7.09-7.12% on September 24-25, as US Treasury yields crossed 5.20%, Brent crude stayed above $100 a barrel and traders priced in a 25-basis-point repo rate hike from the Reserve Bank of India at its October 7 policy review. It hit a 2-year high of 7.16% to 7.17% on September 28, 2026.

Given the G-sec yield data, the Finance Ministry no longer needs to override the formula to justify the freeze on PPF.

Probably not, as the Committee's formula is just a recommendation and not a statutory mandate.

The Finance Ministry usually does smooth rate changes to avoid volatility for retail investors. There is also a fiscal angle as net collections from schemes like PPF feed into the National Small Savings Fund, which currently on-lends to the Centre and states at 9.5%.

So, the current rate structure suits the exchequer. However, there could be a realistic upside scenario for PPF investors in coming quarters if there is a sustained rise in G-sec yields on the back of RBI's tightening cycle. This will gradually build a case for a hike in 2027. For now, however, one may expect another consecutive quarter at 7.1%.

Rules investors should remember

The PPF account matures after 15 years. It allows a minimum annual deposit of ₹500 and a ceiling of ₹1.5 lakh. Interest is compounded annually and the scheme enjoys EEE status as deposit, interest and maturity are all tax-exempt.

The PPF rate is not locked at entry. The rate declared for a quarter applies to the entire outstanding balance. This means, a rate cut or hike would apply to existing corpus from that quarter onward, and a hike would do the same. There is, therefore, no last-day arbitrage in rushing to open an account before September 30, unlike with NSC or SCSS.
