For actuarial valuations under the applicable accounting standards — AS 15, Ind AS 19 or IAS 19 — the discount rate must reflect the yield on high-quality corporate bonds of a duration consistent with the estimated term of the benefit obligation. In India, in the absence of a sufficiently deep market in long-duration high-quality corporate bonds, Government Securities (G-Sec) yields are used as the reference rate — consistently accepted by statutory auditors.

This article presents the FBIL par yield curve as at 30 September 2026 and analyses movement across the curve relative to the prior two quarters — the previous financial year-end (31 March 2026) and the interim half-year point (30 June 2026).

Q2 FY2027 saw the largest quarterly rise in the 10-year G-Sec par yield since June 2022. The 10-year par yield rose 47 bps from Jun 2026 to Sep 2026, reversing the Q1 decline — companies with a 30 Sep 2026 valuation date will see materially lower Defined Benefit Obligations compared to their 30 Jun 2026 position, and broadly similar obligations to 31 Mar 2026.

FBIL G-Sec Par Yield Curve — Quarterly Comparison

The chart below overlays the par yield curves for three valuation dates: 31 March 2026 (FY2026 year-end), 30 June 2026 (Q1 FY2027), and 30 September 2026 (Q2 FY2027). The upward shift from June to September is visible across all tenors, with the steepest moves at the short end.

Historical Trend — 10-Year Par Yield (Quarterly, 2020–Sep 2026)

The interactive chart below plots the quarterly FBIL 10-year par yield since September 2020. This long-term perspective contextualises the current level relative to pandemic-era lows, the 2022 rate-hike cycle, and the easing cycle of FY2025–26.

Factors Driving the Q2 FY2027 Yield Rise

Domestic Supply: OMO Sales

The RBI announced plans for Open Market Operations (OMO) sales of approximately ₹1 lakh crore in FY2027 — the largest net annual bond sale in over a decade. OMO sales drain system liquidity and push up yields by increasing the effective supply of government securities. Markets priced this in through Q2, applying persistent upward pressure especially on the 1–5 year segment.

Elevated Crude and Fiscal Risk

Brent crude traded above $82/bbl for much of the quarter, rekindling concerns about India's import bill and fiscal slippage. Higher crude raises headline CPI, constrains the space for further RBI rate cuts, and increases the market's risk premium on government bonds.

Global Spillover — US Treasury Yields

The US 10-year Treasury yield rose to approximately 5.29% by late September 2026 — near its highest level in over a decade — driven by sticky US inflation and a resilient labour market. Elevated US yields tighten the spread differential with Indian G-Secs, reducing the relative attractiveness for foreign portfolio investors (FPIs) and adding to domestic yield pressure.

RBI Easing Pause

Following rate cuts in February and April 2026 (cumulative 50 bps), the RBI held the repo rate steady at subsequent MPC meetings, citing external uncertainty and upside inflation risks. The pause tempered any further curve bull rally, particularly at the short end.

Bear flattening. The rise was led by the short end: the 1-year par yield rose 69 bps against 47 bps at 10 years and 35 bps at 20 years. The 10yr – 1yr spread narrowed to 106 bps at Sep 26, from 128 bps at Jun 26 and 152 bps at Mar 26. Short and medium tenors are now above their March 2026 levels, while tenors of 15 years and beyond remain slightly below them.

Actuarial Implications — Valuations at 30 Sep 2026

Lower DBO vs June 2026

For companies valuing gratuity, leave encashment, pension, or PRMB obligations at 30 September 2026, the discount rate will be higher than at 30 June 2026 by approximately 35–60 bps (depending on the duration of obligations). This directly reduces the Defined Benefit Obligation (DBO), as the present value of future benefit payments falls with higher discount rates.

As a rough guide: a 50 bps increase in the discount rate reduces the DBO of a scheme with a 10-year modified duration by approximately 4.5–5.0%. For a company carrying a DBO of ₹10 crore, this translates to a reduction of ₹45–50 lakhs — a meaningful actuarial gain flowing through OCI.

Actuarial Gains Through OCI

Under Ind AS 19 and IAS 19, changes in DBO due to experience adjustments and changes in financial assumptions (including the discount rate) are recognised in Other Comprehensive Income (OCI); under AS 15 they are recognised in the profit and loss account. The yield rise in Q2 FY2027 will generate an actuarial gain for most companies — partially offsetting prior-quarter actuarial losses recorded in FY2026 when yields were lower.

Half-Year vs Annual Valuations

Companies that carry formal actuarial valuations at both 31 March and 30 September (for interim financial reporting) must engage their actuary to update all financial assumptions. The discount rate change is the dominant driver of DBO movement for Q2, though the interest cost (unwinding of discount) will also reflect the higher opening discount rate from June 2026.

Duration Matching

The steep short-end rise is a reminder that the discount rate is the rate corresponding to the estimated duration of the obligation. A gratuity scheme with average duration of 9-10 years will reference a 10-year par yield (7.32% at Sep 2026), while a mature pension scheme with 15-year duration references approximately 7.52%. Companies should select rates consistently with the duration profile of each specific scheme.
