Indian government bonds have extended their decline following Bloomberg Index Services' decision to defer including local bonds in its flagship Global Aggregate Index. The benchmark 10-year yield has risen nearly 10 basis points since the deferral announcement, adding to market concerns over heavy debt supply and elevated yields.

Global Index Deferral Impact

The unexpected deferral has disappointed market participants who were anticipating significant foreign inflows. Analysts had expected phased inflows of $10.00 billion to $20.00 billion had the inclusion progressed as planned. The decision has compounded concerns in a market already burdened by worries over heavy state debt issuance.

RBI's Record Bond Purchase Program

The Reserve Bank of India has conducted unprecedented bond purchases to support the market, buying ₹2.54 lakh crores ($27.99 billion) since December through open market and secondary market operations. The central bank is scheduled to purchase another ₹50,000 crores next Thursday, with most market participants initially expecting this to be the final round for the current financial year ending in April.

Expectations for Additional Liquidity Support

"The unexpected deferral raises the probability of one more round of liquidity injection by the Reserve Bank of India in the current quarter," said Abhishek Upadhyay, senior economist at ICICI Securities Primary Dealership. He emphasized that the RBI should continue conducting secondary market bond purchases to alleviate supply pressures.

VRC Reddy, treasury head at Karur Vysya Bank, suggested more substantial intervention may be needed. "The RBI may need to conduct more OMO purchases of around ₹1.50-2.00 lakh crores in February-March, and will have to give out clear yield signals by including liquid papers," he noted.

Market Concerns Over Bond Selection

Traders have expressed frustration with the central bank's focus on relatively illiquid bonds through open market operations this month. Market participants have sought the inclusion of the former benchmark 6.33% 2035 paper in purchase operations. "If you keep on coming out with dead papers, how can you expect any rally," commented a senior trader with a private bank.

Upcoming Market Events

The bond market faces additional uncertainty with the Federal Budget scheduled for February 1 and the RBI's policy decision on February 6. Bond purchases in December and January are already slated to exceed the ₹2.76 lakh crores bought by the central bank between April and November, highlighting the unprecedented scale of intervention required to stabilize the market.

Indian government bonds extended their decline on Wednesday, with the benchmark 10-year bond falling to its lowest level in more than three weeks following Bloomberg's decision to exclude Indian debt from its Global Aggregate Index. The selloff reflects continued market disappointment over the deferred inclusion, which has dampened investor sentiment across the bond market.

Bond Yield Performance

The benchmark 10-year bond yield performance showed significant movement following the index announcement:

Bond yields move inversely to prices, indicating that bond prices have fallen as yields climbed to these elevated levels. The 10-year yield has risen 4.50 basis points since Bloomberg Index Services announced its deferral decision on Tuesday.

Bloomberg Index Decision Impact

Bloomberg Index Services postponed adding Indian bonds to its flagship Global Aggregate Index, stating it will issue another update by mid-year 2026. This decision has triggered widespread selling among most market participants, as investors had anticipated the inclusion would bring significant foreign inflows into Indian debt markets.

The index exclusion has created a challenging environment for Indian bonds, with market sentiment remaining sour following the announcement. Traders and investors are now reassessing their positions in Indian government securities.

Market Activity and Central Bank Intervention

Despite the broad-based selling, one category of investors has been actively purchasing bonds:

The "others" category includes the Reserve Bank of India, corporates, and insurers. Traders suggest this buying pattern indicates the central bank may be actively purchasing in the secondary market, particularly following the redemption of a security on Friday.

Trading Outlook and Risk Factors

Market experts are providing guidance on potential trading ranges and risk factors. Alok Sharma, head of treasury at ICBC Mumbai, noted that in the absence of index inclusion, the 10-year yield may gravitate towards the 6.65%-6.70% band, which could present attractive buying opportunities.

However, traders identified a key risk factor that could disrupt this outlook. The primary threat to buying in this yield range stems from potential escalation of Middle East tensions, which could significantly impact market dynamics.

Broader Market Implications

The bond market weakness has extended to other interest rate instruments. India's overnight index swap rates reflected the sour market sentiment:

Traders continue monitoring developments in the Middle East closely, as oil prices have been rising with benchmark Brent crude reaching a more than two-month peak on Tuesday. These geopolitical factors add another layer of complexity to the Indian bond market outlook.
