• IBC at nine: the Insolvency and Bankruptcy Code resolved Rs 26 lakh crore in debt over nine years; NPAs fell from 10.9 per cent to 2.3 per cent.
• Environment: The IUCN World Heritage Outlook 4 found that 80 per cent of natural World Heritage sites face direct climate risks.

GS area: Economy (Inflation, Data Releases)

MoSPI released September 2025 retail inflation data. This is a critical data day for UPSC.

• Headline CPI: 1.54 per cent (year-on-year, provisional). Down from 2.07 per cent in August.
• Historical comparison: the lowest inflation reading since June 2017, a gap of 99 months.
• Consumer Food Price Index (CFPI): -2.28 per cent. Food was in deflation. Vegetables fell 21 per cent year-on-year. Pulses declined 15 per cent year-on-year.
• Core inflation: 4.6 per cent, up from 4.2 per cent in August. Eight consecutive months above 4 per cent. Core strips out food and fuel.
• Rural-urban split: rural inflation slightly higher than urban, consistent with food's larger weight in the rural consumption basket.
• The paradox: headline inflation was below the RBI's lower tolerance band of 2 per cent while core remained sticky above 4 per cent. This creates a conflicting signal for monetary policy.
• Base effect: September 2024 had seen a food price surge, creating a favourable base for the September 2025 reading.
• Institutional facts: CPI is compiled and released by MoSPI through the National Statistics Office (NSO). The RBI uses it as the inflation target benchmark but does not produce it.
• Statutory target: 4 per cent with a tolerance band of plus or minus 2 percentage points (between 2 and 6 per cent).

The single most tested CPI fact in UPSC: the institution that releases CPI is MoSPI/NSO, not the RBI.

GS area: Economy (Wholesale Price Index)

Wholesale Price Index inflation for September 2025.

• WPI inflation: 0.13 per cent (provisional, year-on-year). Down from 0.52 per cent in August.
• Primary articles: deflation of -3.32 per cent (driven by food commodities).
• Fuel and power: deflation of -2.58 per cent.
• Manufactured products: inflation of +2.33 per cent.
• Base year for WPI: 2011-12 (unlike CPI's 2012 base).
• WPI vs CPI distinction: WPI measures prices at the producer/wholesale level. It does not include services. CPI measures prices at the consumer level and includes services. WPI is released by the Office of the Economic Adviser (OEA), Ministry of Commerce, a different ministry from CPI.

GS area: Economy (Industrial Production)

Index of Industrial Production data for August 2025.

• Overall IIP growth: 4.0 per cent year-on-year, up from 3.5 per cent in July.
• Quick Estimate value: 151.7 against 145.8 in August 2024.
• Sectoral breakdown:
  • Mining: +6.0 per cent (highest sectoral growth).
  • Manufacturing: +3.8 per cent.
  • Electricity: +4.1 per cent.
• Use-based classification:
  • Infrastructure and Construction Goods: +10.6 per cent (highest).
  • Primary Goods: +5.2 per cent.
  • Intermediate Goods: +5.0 per cent.
  • Capital Goods: +4.4 per cent.
  • Consumer Durables: +3.5 per cent.
  • Consumer Non-durables: -6.3 per cent (the only contracting segment).
• Institutional facts: IIP is released by MoSPI. Base year: 2011-12. Released monthly on a two-month lag (August data in October). The negative consumer non-durables reading signals rural demand weakness.

GS area: Economy (Nobel Prizes, Growth Theory)

The Nobel Prize in Economics (Sveriges Riksbank Prize in Economic Sciences) for 2025 was awarded to Joel Mokyr (Northwestern University), Philippe Aghion (Collège de France/INSEAD/LSE) and Peter Howitt (Brown University).

• Prize split: Mokyr receives half; Aghion and Howitt share the other half.
• Mokyr's contribution: used historical analysis to show that sustained growth requires specific social and institutional preconditions, coffeehouses, printing presses, guilds and other structures that enable knowledge circulation. Growth is a "social technology" before it is a mechanical process.
• Aghion and Howitt's contribution: built the mathematical model of "creative destruction", the process where new products and firms continuously replace obsolete ones, driving productivity growth. This formalises Schumpeter's earlier conceptual framework.
• Creative destruction: Joseph Schumpeter coined the concept. New industries, technologies and firms replace old ones. The process is simultaneously destructive (for incumbents) and generative (for the economy).
• Relevance to India: India's growth experience features high-productivity modern sectors (IT, pharmaceuticals) coexisting with low-productivity traditional sectors. The Aghion-Howitt framework analyses when creative destruction works and when it stalls.

GS area: Environment (Biodiversity, World Heritage)

The IUCN World Heritage Outlook 4 was released at the IUCN World Conservation Congress in Abu Dhabi.

• Frequency: the Outlook is published every four years. Previous editions: 2014, 2017, 2020.
• Overall picture: approximately 65 per cent of World Heritage natural sites are in stable or improving condition since 2020. However, 80 per cent of natural sites face direct climate risks.
• India's sites assessed (7 natural and mixed):
  • Rated "Good": Khangchendzonga (Sikkim).
  • "Good with Some Concerns": Kaziranga, Nanda Devi, Valley of Flowers, Keoladeo.
  • "Significant Concern": Western Ghats, Manas (Assam; transboundary with Bhutan), Sundarbans (West Bengal; transboundary with Bangladesh).
• Western Ghats: lost 5 per cent of evergreen forest cover. Spans Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu.
• Top threats globally: climate change has replaced hunting as the number one threat. Tourism, invasive alien species and infrastructure are also in the top five.

GS area: Internal Security (Smuggling, Enforcement)

The Directorate of Revenue Intelligence (DRI) conducted Operation Golden Sweep at Chhatrapati Shivaji Maharaj International Airport, Mumbai.

• Seizure: 10.488 kilograms of 24-carat gold valued at Rs 12.58 crore.
• Method of concealment: transit passengers from Dubai, Singapore, Bangkok and Dhaka hid gold in egg-shaped wax capsules inside their bodies.
• Institutional significance: DRI functions under the Central Board of Indirect Taxes and Customs (CBIC), Ministry of Finance. It is the apex intelligence organisation for anti-smuggling operations in India.
• Detection: the operation revealed insider assistance from airport personnel, suggesting an organised supply chain.
