Weekly Current Affairs (September 2026 – Week 4) – Exam Revision Notes
1) International Current Affairs
New Arctic Security Agreement
The United States, Denmark and Greenland have reached a new security agreement that would allow Washington to expand its military presence in Greenland while preventing adversarial countries from establishing military bases there.
Greenland is increasingly strategically important because of its location between the Arctic and the North Atlantic. The United States already operates Pituffik Space Base, formerly called Thule Air Base, in north-western Greenland. The base supports missile warning, missile defence, space surveillance and satellite operations.
US Deployed ‘Space Control’ Weapons in Orbit
The United States has publicly acknowledged for the first time that it has deployed “space control” weapons in Earth orbit. On 14 September 2026, U.S. Air Force Secretary Troy Meink said that the U.S. Space Force has on-orbit systems capable of defending American forces against hostile actions in space.
Indonesia’s Nickel Supply Curbs
Indonesia, which accounts for more than 60% of global nickel production, has tried to curb oversupply by reducing mining quotas, strengthening environmental controls and adjusting ore prices. The measures followed Indonesia’s 2020 ban on nickel ore exports, which encouraged domestic processing capacity and helped the country become the world’s dominant nickel producer.
The International Nickel Study Group (INSG) revised its 2026 outlook in April, changing its earlier forecast of a 2,61,000-tonne surplus to a 32,000-tonne deficit, mainly due to lower expected Indonesian production.
OneSCD Global Partnership for Sickle Cell Care
India co-hosted the launch of OneSCD: A Global Partnership to Advance Equity and Transform Sickle Cell Care on the sidelines of the 81st United Nations General Assembly (UNGA81) in New York. It aims to strengthen global cooperation and promote equitable and accessible care for people living with Sickle Cell Disease (SCD).

Supreme Court Strikes Down Maharashtra’s Methanol Denaturation Rules
The Supreme Court on 18 September 2026 struck down certain provisions of the Maharashtra Poisons Rules, 1972 relating to the sale and use of methanol. The rules required methanol sold to non-drug manufacturers to be mixed with colouring and bittering agents. The Court held these restrictions placed an excessive burden on legitimate industries and were not proportionate to the objective of preventing illicit liquor.
| Key Detail | Fact |
|---|---|
| Article 14 | Equality and protection against arbitrary State action |
| Article 19(1)(g) | Right to practise any profession or carry on trade, occupation or business |

Maharashtra Women Farmers’ Empowerment Bill
In July 2026, Maharashtra passed the Women Farmers’ Empowerment Bill, becoming the first Indian State to give enforceable legal recognition to women as farmers irrespective of land ownership. It provides a Woman Farmer Certificate to women engaged in agriculture for at least one agricultural season a year.
It recognises landless cultivators, landless livestock rearers, agricultural labourers, plantation labourers and pastoralists. Women often work on family land without their names in land records, restricting access to schemes, credit, subsidies, technology and extension services. The Bill also provides a database of women farmers; linking certificates with Agri Stack and issuing Farmer IDs can integrate them into the digital agricultural ecosystem.
National Institute of Sowa Rigpa (NISR) – Leh; Ladakh

International Payment Systems
SWIFT (Society for Worldwide Interbank Financial Telecommunication) is a Belgium-based global financial messaging network used by banks for cross-border payments. Growing use of financial sanctions and concerns over dependence on the U.S. dollar-based system have encouraged alternatives.
CIPS (Cross-Border Interbank Payment System), backed by the People’s Bank of China, was launched in 2015 to promote international use of the yuan (renminbi); it processed an average of 679.8 billion yuan per day in 2025, though its scale remains smaller than established systems. Russia developed SPFS (System for Transfer of Financial Messages) in 2014 amid Western sanctions; after Russian banks were excluded from SWIFT in 2022, SPFS became an important channel.
Project mBridge is a multi-CBDC (Central Bank Digital Currency) platform for cross-border payments involving China, Hong Kong, Thailand, the UAE and Saudi Arabia. It developed the mBridge Ledger, a blockchain-based platform for direct peer-to-peer settlement using CBDCs without correspondent banks.
| System | Full Form | Country / HQ | Key Purpose |
|---|---|---|---|
| SWIFT | Society for Worldwide Interbank Financial Telecommunication | Belgium / La Hulpe | Global financial messaging network |
| CIPS | Cross-Border Interbank Payment System | China / Shanghai | Cross-border yuan payments and settlement |
| SPFS | System for Transfer of Financial Messages | Russia / Moscow | Russian alternative to SWIFT financial messaging |
| mBridge | Multiple CBDC Bridge | Multi-country / no single HQ; jointly developed by participating central banks | Cross-border CBDC payments and settlement |
| SEPAM | Sistema de Electronic Payment Messaging | Iran / Tehran | Domestic/interbank financial messaging |

5) Science & Technology
Methanol – CH₃OH
Methanol (CH₃OH) is a colourless, highly toxic and flammable liquid also known as methyl alcohol or wood alcohol. It is mainly an industrial raw material, used to produce formaldehyde, paints, solvents, plastics and other chemicals. It is not meant for human consumption — even small amounts can cause serious poisoning, blindness or death — and it can be misused in making illicit liquor.
Canal-Top Photovoltaics (CTPV)
Canal-top photovoltaics (CTPV) installs solar panels on elevated structures above irrigation and water-supply canals. Unlike floating solar, CTPV structures span the canal or run along its banks without obstructing water flow. It requires virtually no additional land — in Punjab, 20 MW of CTPV is estimated to have saved nearly 100 acres — and reduces evaporation losses.
| Key Detail | Fact |
|---|---|
| India’s first canal-top solar | Mehsana, Gujarat — 2012 |
| 1-MW Narmada Canal system | Saves ~9 million litres of water and generates ~1.6 million units per year |
| India’s potential (2024 assessment) | ~131 GW (CTPV + canal-bank solar) |
| Top-potential States | Uttar Pradesh, Bihar, Karnataka, Andhra Pradesh, Punjab |
| Challenges | High installation cost, structural requirements, maintenance, grid connectivity |
IMEI Tampering – 15-Digit IMEI
The International Mobile Equipment Identity (IMEI) is a unique 15-digit number identifying a mobile device on a telecom network. The first eight digits form the Type Allocation Code (TAC), identifying the device model; the GSMA (Global System for Mobile Communications Association) oversees TAC allocation. A dual-SIM phone generally has two IMEI numbers.
The Government has highlighted IMEI tampering as a threat to telecom security and digital sovereignty. Removing or altering an IMEI, or knowingly possessing, producing or using hardware/software for such alteration, is unlawful.
Bio-Based Biodegradable Plastic
The Union Government launched the commercial use of bio-based biodegradable plastic based on Polylactic Acid (PLA). The initiative is being taken forward by Balrampur Chini Mills Limited (BCML) under the BioE3 (Biotechnology for Economy, Environment & Employment) framework.
