The RBI announced the operation after reviewing prevailing and evolving liquidity conditions.

What does VRRR do?

A Variable Rate Reverse Repo allows RBI to absorb surplus liquidity from banks through an auction-based mechanism.

Think:

Excess liquidity in banking system → RBI absorbs liquidity → short-term money-market conditions are managed

Why important?

This is liquidity management, not necessarily a change in the policy repo rate.

Prelims Concept

Repo: RBI lends to banks.

Reverse Repo: Banks park funds with RBI.

VRRR: RBI absorbs liquidity through a reverse-repo operation where the rate is determined through auction.

Static Linkage

GS-III

• Monetary policy
• Liquidity management
• Money market
• RBI’s operating framework
• Monetary transmission

Possible MCQ

Consider the following statements:

1. VRRR operations can be used to absorb surplus liquidity.
2. A VRRR auction necessarily implies a change in the policy repo rate.
3. VRRR is associated with the Liquidity Adjustment Facility.

A significant development in regenerative agriculture is India’s first reported farm-level soil-carbon payments.

More than 2,500 farmers in Punjab and Haryana are to receive digital payments, with over ₹2.9 crore being disbursed.

Farming practices involved

• Direct Seeded Rice (DSR)
• Reduced tillage
• Crop-residue management

These practices can contribute to:

Higher soil carbon + lower water use + lower residue burning + reduced emissions

Carbon-credit chain

Farm practice

↓

GHG reduction / soil-carbon increase

↓

Measurement

↓

11. ENVIRONMENT — GLOBAL WATER SECURITY

The WMO State of Global Water Resources 2025, released on 17 September, is an important ongoing environment topic for today’s preparation.

WMO reported that 2025 was one of the driest years for global river discharge in more than three decades, while the water cycle has become increasingly erratic and unpredictable. It also reported continuing glacier loss and declining land-based freshwater storage.

Why important for India?

Water security is connected to:

• Himalayan glaciers
• Monsoon variability
• Groundwater
• Agriculture
• Hydropower
• Urbanisation
• Floods and droughts

Conceptual linkage

Climate change → Hydrological-cycle changes → Extreme rainfall/drought → Agriculture & water stress → Food security

GS-I + GS-III

This is a strong geography + environment integrated topic.

12. CLIMATE — STRONG EL NIÑO CONTINUES

The WMO expects the current El Niño to strengthen substantially, with an exceptionally high likelihood of persistence into early 2027.

El Niño basics

El Niño = abnormal warming of central/eastern tropical Pacific Ocean

It can alter:

• Global rainfall
• Temperature
• Drought risk
• Flood risk
• Agriculture
• Fisheries

India linkage

El Niño has historically been associated with changes in Indian monsoon behaviour, although not every El Niño produces the same Indian rainfall outcome.

Prelims Trap

Do not write:

El Niño always causes drought in India.

Correct:

El Niño can influence the Indian monsoon, but its actual impact depends on other ocean-atmosphere factors.

13. GOVERNANCE — SWACHHATA HI SEVA

The Swachhata Hi Seva 2026 campaign has begun nationally.

The campaign includes public participation and cleanliness activities, with the government adopting a whole-of-government approach.
