Overview

October 2023. US 10 year treasury yield crossed 5% for the first time since 2007. FIIs pulled approximately $2 billion from Indian equities within the same week. The Nifty fell 3%. Treasury yield meaning at its most functional: the rate at which the market lends money to the government. When that rate becomes attractive enough, every other asset class competes against it, and loses until it reprices.

Final Takeaways:

• Treasury bond yield and bond price move inversely. Rising yield = falling price, and vice versa
• 10 year treasury yield in India tracks around 6.9-7.1% in FY26. Above 7.5%, long-duration G-Secs become attractively priced for rate-fall scenarios
• Treasury yield curve inversion has preceded every US recession since 1960. India’s brief inversions in 2018-19 and 2022-23 signalled monetary tightness
• Bond yield calculation: Yield = (Annual Coupon / Current Price) × 100 for quick approximation. YTM is the precise measure
• Open demat account for NSE debt segment access to government securities india alongside equity investing.

What are Treasury Yields?

Treasury bond yield : the price which the government would have to pay for borrowing cash on this bond, also a percentage of the bond value on the open market today. When a bond goes up in price it will fall in yield; when it sells low, it is up in price and yield.

India’s treasury securities:

• 91-day, 182-day, 364-day T-Bills: zero coupon, auctioned weekly by RBI
• G-Secs (5-40 year): semi-annual coupon. The 10-year G-Sec government bond yield is India’s domestic benchmark
• State Development Loans (SDLs): 20-30 basis points above equivalent G-Sec
• Sovereign Gold Bonds: 8-year, 2.5% annual interest plus gold price movement

Bond yield calculation: Yield = (Annual Coupon / Current Market Price) × 100. YTM is more precise and published directly by RBI for active G-Secs.

Why Are Treasury Yields Important?

Every loan in the economy prices relative to the government bond yield. A 50 basis point rise in India’s 10-year G-Sec yield typically translates to a 25-40 basis point increase in home loan rates within 2-3 months.

• India 10-year G-Sec yield: directly sets the floor for corporate bond pricing, home loan rates, and equity discount rates
• US 10 year treasury yield: determines whether FII money stays in India or exits for risk-free US returns. US yield above 4.5% has historically triggered sustained FII selling from Indian equities.

How Do Treasury Yields Affect the Stock Market?

It depends on why yields are rising:

Growth-driven yield rise: equities can rise alongside G-Sec yields. Between 2021 and 2023, India’s G-Sec yields rose from 5.9% to 7.5% while Nifty 50 rose 60%. Earnings grew fast enough to absorb the higher discount rate.

Inflation-driven yield rise: equities fall. US Fed raising rates from 0% to 5.5% between 2022 and 2023 pushed the US 10 year treasury yield from 1.5% to 5%+. FIIs had a 5% risk-free alternative. They sold Indian equities.

Sector impacts:

• Banks: profit from a steep government bond yield curve. Flat or inverted curves compress bank margins
• Real estate and NBFCs: directly repriced when long-term treasury yield rises
• IT exporters: fall hardest when US 10 year treasury yield rises sharply.

What Factors Influence Treasury Yields?

Five drivers for Indian G-Sec yields:

• RBI’s repo rate: sets the floor for short-term government securities yields directly
• Domestic CPI: if India’s CPI is 5.5%, the 10-year G-Sec yields 6.5-7.5%. Markets cannot sustainably offer a government bond yield below inflation
• US Federal Reserve: a hawkish Fed meeting can move Indian G-Sec yields 10-15 basis points even with no domestic change
• RBI’s OMO: buying treasury securities in the secondary market suppresses yields; selling raises them
• India’s fiscal deficit: more government borrowing = more treasury securities supply = higher yields

How to Interpret Treasury Yield Charts?

The treasury yield curve plots yields across all G-Sec maturities. Three shapes:

• Normal (upward sloping): short rates below long rates. Banks profit from this shape; they borrow short and lend long
• Flat: 91-day T-Bill approaching the 10-year G-Sec yield. Market expects rate cuts ahead, or economic uncertainty is high
• Inverted: short rates exceeding long rates. Has preceded every US recession since 1960. India’s treasury yield curve inverted briefly in 2018-19 and again during the 2022-23 rapid rate hike cycle. Duration of inversion matters more than the mere fact of it

How Can Investors Use Treasury Yields?

Three access routes for retail investors to government securities india:

• RBI Retail Direct: direct G-Sec purchase from RBI with zero brokerage. KYC-linked to Aadhaar and PAN
• NSE/BSE Debt Segment: through a KYC-verified demat account at a SEBI-registered broker
• Gilt mutual funds: professionally managed, daily NAV liquidity, duration risk managed by the fund

Portfolio signals from India’s 10 year treasury yield:

• Above 7.5%: long-duration G-Secs attractively priced for rate-fall scenarios
• Inverted treasury yield curve: overweight short-term T-Bills (higher yield, near-zero duration risk)
• Steepening curve: long-duration G-Secs and gilt funds benefit.

What Are Common Misconceptions About Treasury Yields?

• Treasury securities are risk-free

Credit risk-free, not price risk-free. A 40-year G-Sec at 7.2% loses approximately 15-17% in market value if yields rise 1% to 8.2%

• Rising yields mean the economy is doing well. 

Yields also rise when inflation is out of control or when foreign investors exit the currency. Direction matters less than the reason for the move

• India and US 10 year treasury yields move together. 

Correlated through the FII channel, not mechanically linked. India’s treasury yield curve is driven by RBI policy and domestic inflation; the US 10 year treasury yield by the Federal Reserve and global safe-haven demand.

Conclusion

Treasury yield meaning for an equity investor: the rate that determines whether FII money stays in India or leaves. For a bond investor: the absolute return available from the government for a given duration. The 10 year treasury yield in India and the US are two numbers worth tracking alongside the Nifty 50.
