Term Premium

The term premium answers a question lurking behind every long-dated government bond: why should you accept locking your money away for ten years, when you could lend short and stay flexible? The extra yield that compensates you for that commitment is the term premium.

The uncertainty you are paid for

When you buy a 10-year G-Sec instead of rolling over a series of short-term bonds, you take on real risks. Inflation could surge and erode your fixed coupon; interest rates could rise and crush the bond's price if you need to sell early. The term premium is the cushion of extra yield investors demand for bearing this uncertainty over a long horizon. It is the part of a long bond's yield that is not explained simply by where people expect short rates to average.

Why it matters in India

The shape of the yield curve, the gap between long and short government bond yields, reflects this premium plus rate expectations. A steep curve, where 10-year yields sit well above the repo rate, signals a fat term premium, often driven by worries about heavy government borrowing, fiscal deficits or future inflation. A flat curve signals the opposite. India's term premium is sensitive to the size of the government's borrowing programme and, increasingly, to foreign flows after the country's inclusion in global bond indices, which added a large, steady buyer of longer-dated debt and can compress the premium.

What investors should do with it

For a debt-fund investor, the term premium is the heart of the duration decision. A generous premium can reward those willing to hold long-duration or gilt funds, but the same long bonds inflict the steepest mark-to-market losses if rates rise unexpectedly. When the premium is thin, you are taking duration risk for little extra return, and shorter-maturity funds make more sense.

The verdict: long bonds pay you to bear uncertainty, so demand a meaningful term premium before stretching for duration, and never reach for it just because the headline yield looks high.
