Current Affairs – March 28, 2026

{GS1 – Geo} Helium Shortage Crisis *

• Context (NIE): Iranian missile strikes on the Ras Laffan LNG hub in Qatar disrupted LNG production, cutting off one-third of global helium supply.

• Byproduct: Helium is primarily obtained as a byproduct of natural gas extraction. Therefore, any interruption in LNG production directly decreases helium output.
• Concentration: Qatar and the U.S. account for 70-75% of the world’s helium supply. Almost all Qatari output is refined at Ras Laffan.
• Export Chokepoint: Almost all of Qatar’s helium exports pass through the Strait of Hormuz.

About Helium

• Helium is a colourless, odourless, chemically inert noble gas with the lowest boiling and melting points of any element.
• Abundance: It is the second most abundant element in the universe but remarkably rare on Earth.
• Origin: Most terrestrial helium forms through radioactive decay of uranium and thorium in the Earth’s crust over billions of years.
• Atmospheric Loss: Once released into the air, helium rises to the top of the atmosphere and escapes Earth’s gravity into space.
• Global Supply: The U.S., Qatar, Russia and Algeria control the majority of the world’s helium supply.

Applications of Helium

• Medical Use: ~30% of global helium is used to cool superconducting magnets in MRI scanners.
• Manufacturing: It offers a chemically inert environment and efficient cooling for manufacturing semiconductors and fibre optic cables.
• Rockets: As helium stays gaseous even at extremely low temperatures, it is used to pressurise rocket fuel tanks, including liquid hydrogen tanks.
• Deep-Sea Diving: It is added to oxygen cylinders for deep-sea diving to prevent nitrogen narcosis and oxygen toxicity.

{GS3 – IE} India’s Forex Reserves as Shield Against External Shocks **

• Context (IE): RBI recently asserted that India’s forex reserves remain adequate to cushion external shocks despite the rupee weakening to record lows.

Forex Reserve Components

• Foreign Currency Assets (FCA): They are the largest and most liquid component, held in major currencies (USD, Euro, Pound, Yen).
• Gold Reserve: Includes physical gold and deposit accounts at market prices; they are a last-resort asset, not for routine intervention.
• Special Drawing Rights: SDRs are IMF-allocated assets based on five major global currencies.
• Reserve Tranche Position: RTP represents India’s IMF quota, serving as an emergency credit line.

External Shock Absorption Mechanisms

• Exchange Management: RBI maintains a managed float regime, selling dollars to prevent rupee depreciation and trade instability.
• Outflow Cushion: Large reserves meet sudden dollar demand during FPI exits, stabilising financial markets during global risk-off phases.
• Import Security: Reserves ensure uninterrupted payments for crude oil, fertilisers, and machinery during external supply shocks or price hikes.
• Macroeconomic Stability: High forex reserves indicate sovereign credibility, reduce borrowing costs, and strengthen investor confidence.

Key Concerns Over India’s Forex Reserve Adequacy

• Net Reality: Headline reserve value overstates strength, as $68 billion in forward liabilities reduces usable FCA reserves to below $500 billion.
• Import Pressure: Rising energy prices are increasing import bills, which can push import cover toward 2013 taper tantrum vulnerability levels.
• Flow Dependence: India’s reserves depend on volatile capital inflows, making them vulnerable to sudden capital flight during global risk aversion.
• Metric Gap: Traditional adequacy metrics cover short-term debt but overlook risks from large portfolio equity outflows during prolonged market stress.
• Policy Trade-off: Aggressive dollar sales are depleting rupee liquidity, prompting the RBI to balance exchange rate stability with tightening domestic credit conditions.

• Rising Electrification: Increased household electrification (~99%) and rural connectivity are expanding the consumer base.
• Higher Appliance Usage: Growing use of ACs, heaters, geysers, and electronic devices is raising demand.
• Urbanisation: Rapid urbanisation and rising incomes lead to energy-intensive lifestyles.
• Infrastructure Expansion: Growth in data centres, AI, metro systems, and infrastructure projects add electricity demand.

{GS3 – Envi} Microplastics in Coastal Ecosystems **

• Context (TH): A recent study has found low levels of microplastics on Chennai’s coast and highlighted their significant long-term ecological and health risks.

About Microplastics

• Microplastics (MPs) are tiny plastic particles less than 5 mm in size. They are non-biodegradable.
• Types: Primary MPs are intentionally manufactured small (e.g., microbeads); Secondary MPs are formed by breakdown of larger plastic waste.
• Sources: Originate from plastic waste, fishing gear, synthetic textiles (i.e. nylon), cosmetics, tourism waste, and urban sewage/drainage.
• Breakdown of Plastics: By fragmentation of larger plastic waste due to sunlight, waves, and weathering.
• Particle Size: The majority are less than 1000 µm, making them easily ingested by marine organisms.

Ecological and Health Impacts of Microplastic Pollution

• Harm to Organisms: Ingested by worms, fish, and shellfish, causing blockage, injury, & reduced survival.
• Food Chain Contamination: Move up the food chain, affecting larger animals and eventually humans.
• Habitat Disruption: Alter sediment structure & marine ecosystems, impacting biodiversity & ecology.
• Presence in Human Organs: Recent studies have found microplastics in the brain, liver, and kidneys, with possible links to heart disease and neurological disorders.
• Ecosystem-Level Impact: Affects marine biodiversity, microbial systems, and ecosystem stability.

Way Forward for Coastal Plastic Management

• Waste Management: Need for segregation, recycling, and scientific disposal of plastic waste. Globally, 19–23 million tonnes of plastic enter aquatic ecosystems annually.
• Extended Producer Responsibility (EPR): EPR incentivises eco-friendly product design and waste reduction at source.
• Ban on Microbeads: India banned several single-use plastic items (2022); however, microbeads still lack strict regulation. ~45% of personal care products in India contain microbeads.
• Control of Key Sources: OECD data show that washing synthetic clothes and tyre wear contribute ~62% of microplastic emissions.
• Circular Economy: Encourage the use of biodegradable materials, recycling, and reuse models. Reduce dependence on fossil-fuel-based plastics (the plastic industry uses ~6% of global oil).
