GK One-Liners

What: The Centre proposed a major Goods and Services Tax (GST) overhaul with two primary slabs—5% and 18%—along with a 40% rate for sin goods (tobacco, aerated beverages, luxury items). The reform aims to simplify the current multi-rate structure, fix inverted duty anomalies, speed up registrations, and automate refunds, with rollout targeted for Q3 FY26.

How: Currently, GST has multiple slabs (0%, 5%, 12%, 18%, 28%) plus cess on certain items, creating complexity in classification and compliance. Rationalisation to fewer slabs would reduce disputes, simplify input tax credit claims, and address inverted duty structures where inputs are taxed higher than outputs—a long-standing concern of manufacturers.

Why: GST structure, GST Council functioning, and indirect tax reforms are essential topics for UPSC GS-III (Economy) and banking exams. Understanding concepts like input tax credit, inverted duty structure, compensation cess, and the federalism aspects of GST (Centre-State revenue sharing) demonstrates comprehensive knowledge of India’s tax system since July 2017 implementation.

What: From 15 August 2025, the National Highways Authority of India (NHAI) rolled out a FASTag Annual Pass for private vehicles across approximately 1,150 toll plazas nationwide. The pass offers unlimited travel for ₹3,000 for either one year or 200 crossings (whichever comes first), with activation via the Rajmargyatra app and support through an upgraded 1033 helpline.

How: The Annual Pass provides cost savings for frequent highway users compared to per-trip toll charges. Users can purchase and activate the pass digitally through the Rajmargyatra app, which also provides real-time toll information, trip planning, and grievance redressal. This initiative supports NHAI’s transition toward fully digital, barrier-free tolling.

Why: FASTag, electronic toll collection, and NHAI’s highway monetisation initiatives are important for UPSC GS-III (Infrastructure) and banking exams. Understanding toll policy evolution—from manual collection to ETC to MLFF (Multi-Lane Free Flow)—and digital infrastructure like Rajmargyatra demonstrates awareness of India’s transportation sector modernisation.

What: India’s foreign exchange reserves rose by $4.74 billion to $693.62 billion as of 8 August 2025. The increase was supported by gains in Foreign Currency Assets (FCA) and gold holdings, strengthening India’s external sector buffers and import cover capacity.

How: Forex reserves comprise Foreign Currency Assets (largest component), gold reserves, Special Drawing Rights (SDRs), and Reserve Tranche Position with the IMF. The Reserve Bank of India (RBI) manages these reserves to ensure exchange rate stability, meet external payment obligations, and maintain market confidence during global volatility.

Why: Forex reserves, their composition, and RBI’s reserve management are fundamental topics for banking exams and UPSC GS-III (Economy). Understanding import cover (months of imports reserves can finance), the difference between reserves and foreign debt, and factors affecting reserve levels (FPI flows, trade balance, remittances) demonstrates macroeconomic awareness.

What: Indian Navy ships INS Rana (destroyer) and INS Jyoti (fleet tanker) reached Colombo for SLINEX-25 (Sri Lanka-India Naval Exercise), conducted from 14-18 August 2025. The exercise comprised harbour-phase professional exchanges and sea-phase operational drills to deepen maritime interoperability between the two navies.

How: SLINEX is a bilateral annual exercise that alternates between Indian and Sri Lankan waters. The harbour phase includes cross-deck visits, subject matter expert exchanges, and planning conferences. The sea phase features manoeuvres, communication exercises, helicopter operations, and search-and-rescue drills, building operational coordination for regional maritime security.

Why: India’s naval exercises with neighbours—SLINEX (Sri Lanka), SIMBEX (Singapore), CORPAT (Thailand, Indonesia), MILAN (multilateral)—are important for UPSC GS-II (International Relations) and defence examinations. Understanding the strategic importance of Indian Ocean region, SAGAR (Security and Growth for All in the Region) doctrine, and India’s maritime neighbourhood engagement demonstrates awareness of India’s naval diplomacy.

What: ISRO established a space-science laboratory at Mechuka Government Higher Secondary School in Arunachal Pradesh’s Shi-Yomi district. Created in collaboration with the state government and Muskaan Foundation, the lab promotes hands-on STEM (Science, Technology, Engineering, Mathematics) learning in one of India’s most remote regions near the China border.

How: The laboratory provides students access to space science equipment, astronomical observation tools, and educational materials about ISRO’s missions. Such outreach initiatives aim to inspire scientific curiosity among students in underserved areas, potentially nurturing future scientists and engineers from India’s northeastern frontier regions.

Why: ISRO’s educational outreach, STEM promotion, and development initiatives in border areas are relevant for UPSC GS-III (Science & Technology) and GS-II (Governance). Understanding how scientific institutions engage with remote communities and promote aspirational development in strategic regions demonstrates awareness of inclusive growth and capacity building in frontier areas.

What: Northeast Frontier Railway (NFR) signed a Memorandum of Understanding with IIT Guwahati to replace conventional plastics with biodegradable alternatives on trains. The initiative begins with compostable green bed-roll bags to reduce railway waste, supporting India’s commitment to eliminating single-use plastics.

How: IIT Guwahati’s research on bioplastics from agricultural waste and natural polymers provides eco-friendly alternatives to petroleum-based plastics. The partnership will develop, test, and scale biodegradable materials for railway applications including packaging, disposable items, and linens—potentially creating a model for other railway zones and transport sectors.

Why: Single-use plastic ban (effective from July 2022), Extended Producer Responsibility (EPR), and sustainable alternatives are important topics for UPSC GS-III (Environment). Understanding industry-academia partnerships for green solutions, circular economy principles, and the railway sector’s environmental initiatives (like Swachh Rail) demonstrates awareness of sustainability transitions in public services.
