S&P Upgrades India’s Sovereign Rating to ‘BBB’
Basics & Context
- What is a sovereign credit rating?
- An independent assessment of a country’s ability and willingness to meet debt obligations.
- Issued by rating agencies (S&P, Moody’s, Fitch).
- Impacts borrowing costs, FDI flows, and global investor perception.
- Who is S&P Global?
- Standard & Poor’s Global Ratings – among the “Big Three” agencies along with Moody’s and Fitch.
- Known for sovereign, corporate, and financial market ratings.
- Rating Scale (simplified):
- Investment grade: AAA, AA, A, BBB.
- Speculative (junk): BB, B, CCC, etc.
- India’s shift: BBB- (lowest investment grade, 2007) → BBB (2025).
- Short-term rating: A-3 → A-2 (stronger short-term repayment capacity).
- Significance of the 2025 Upgrade:
- First upgrade in 18 years.
- Reflects stronger fundamentals post-pandemic.
- Aligns with India’s ambition to be a top-3 global economy by 2030.
Relevance: GS 3(Indian Economy)
Why the Upgrade Happened
- Strong GDP Growth:
- Post-pandemic rebound → avg. 8.8% (FY22–FY24).
- Projection: 6.8% annually next 3 years (fastest in Asia-Pacific).
- Fiscal Discipline:
- Centre’s deficit: 4.8% (FY25), target 4.4% (FY26).
- General govt. deficit: expected fall from 7.3% (FY26) → 6.6% (FY29).
- Infrastructure push (~5.5% of GDP) funded without widening CAD.
- Monetary Stability:
- Inflation kept within RBI’s 2–6% band since 2015.
- CPI avg. 5.5% (3 yrs), but dropped to 1.6% (July 2025).
- Repo rate eased to 5.5% (Feb–July 2025).
- External Stability:
- Modest net external asset position.
- CAD small, weaker rupee improving export competitiveness.
Fiscal & Debt Dynamics
- Debt Profile:
- Pandemic spike: +9–13% of GDP debt increase.
- Now reduced to +7.8% net debt/GDP.
- Capex Strategy:
- Union govt. capex: ₹11.2 trillion (3.1% of GDP, FY26).
- Public investment (centre + states): ~5.5% of GDP.
- Focus: infra, logistics, energy transition.
- Quality of Spending:
- Shift from subsidies to capital formation.
- Credibility reinforced as deficits fall while infra rises.
Economic & Financial Implications
