Current Affairs 15 September 2026: National News
1. Sixth All India Official Language Conference
The 6th All India Official Language Conference and Hindi Diwas-related celebrations were held in Maharashtra, with Union Home Minister Amit Shah addressing the inaugural session. The conference is organised by the Department of Official Language under the Ministry of Home Affairs.
For UPSC, Articles 343 and 351 of the Constitution are important. Article 343 deals with the official language of the Union, while Article 351 directs the Union to promote the spread and development of Hindi.
2. National Engineers’ Day 2026
National Engineers’ Day is observed in India on 15 September every year to commemorate the birth anniversary of Bharat Ratna awardee Sir Mokshagundam Visvesvaraya.
The day highlights the contribution of engineers to infrastructure, industrial development, technological innovation and nation-building.
Economy and Banking Current Affairs
3. India’s WPI Inflation Rises in August 2026
India’s Wholesale Price Index (WPI)-based inflation increased to 9.92% in August 2026, according to recent data. The increase was influenced by higher prices across fuel and power, manufactured products and food-related components.
Meanwhile, CPI retail inflation stood at 4.82% in August 2026, with food inflation remaining an important factor. Rural inflation was higher than urban inflation.
UPSC Link:
Candidates should understand the difference between CPI and WPI, their components, base effects and their relevance to monetary policy.
4. UPI Payment Charges and MDR Debate
A government notification concerning electronic payments has renewed discussion around charges on UPI transactions. Payments of up to ₹2,000 through UPI remain protected from charges under the notified framework, while the possibility of merchant-related charges on higher-value transactions has generated discussion.
This is important for banking examinations as well as UPSC because UPI is central to India’s digital-payment ecosystem and financial inclusion.
Science and Technology
5. EOS-05 Strengthens India’s Earth Observation Capability
The EOS-05 mission is an important recent development in India’s space programme. ISRO placed EOS-05 into geostationary orbit after its launch aboard GSLV-F17.
The satellite operates at approximately 36,000 km above Earth and is designed to provide continuous Earth observation. Its capabilities can support applications such as disaster management, agriculture, environmental monitoring and strategic surveillance.
EOS-05 is particularly significant because geostationary Earth observation can provide continuous monitoring rather than periodic observations from lower orbits.
6. GalaxEye Receives US Patent
Bengaluru-based space technology startup GalaxEye has received a US patent related to its satellite imaging technology. The development highlights the growing role of Indian private-sector companies in advanced space technology and Earth observation.
This development can be linked with India’s broader policy of encouraging private participation in the space sector.
Defence and Security
7. IAF Dronathon 2026
The Indian Air Force Dronathon-2026 was inaugurated at the Pokhran Field Firing Range in Jaisalmer, Rajasthan and is being conducted from 14–16 September 2026.
The initiative focuses on testing and evaluating unmanned aerial systems under realistic operational conditions. Areas include:
- Drone surveillance and reconnaissance
- Autonomous systems
- Drone swarms
- Electronic warfare
- Counter-UAS capabilities
- Indigenous defence technologies
The event also provides Indian startups, MSMEs and defence companies with an opportunity to align emerging technologies with operational requirements of the Indian Air Force.
International Relations and Economy
8. India–MERCOSUR Preferential Trade Agreement Talks
India and MERCOSUR have launched negotiations to expand their Preferential Trade Agreement (PTA).
MERCOSUR is a major South American regional economic bloc. Greater trade engagement with the grouping can help India diversify export markets and strengthen economic relations with Latin American countries.
For UPSC, remember that MERCOSUR is associated with South American regional economic integration.
Environment and Agriculture
9. Badri Cattle and Indigenous Breed Conservation
India has achieved a notable milestone in indigenous cattle conservation with the production of the country’s first Badri calf using Ovum Pick-Up and In Vitro Fertilization (OPU-IVF) technology at Pantnagar.
Badri cattle are an indigenous breed associated with the Himalayan region, particularly Uttarakhand. Assisted reproductive technologies can help multiply elite germplasm and support conservation of indigenous livestock breeds.
Sports Current Affairs
10. India Wins Women’s Asia Cup 2026
