Helium Shortage Crisis

• 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.

India’s Forex Reserves as Shield Against External Shocks

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

Current Scenario of India’s Forex Reserve

• Reserve Stock: India’s headline foreign exchange reserves remain close to $710 billion.
• Import Cover: It is currently sufficient for 11–12 months of imports.
• Debt Cover: Reserve stock stands at around 95% of India’s external debt outstanding.
• FPI Outflows: Foreign portfolio investors withdrew ~$12.1 billion from Indian equities (March 2026).

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.

India’s Power Demand Hits Five-Year High

• India’s power demand in Jan–Feb 2026 hit a five-year high, driven not by one cause but by a combination of extreme weather shifts and long-term structural growth.
• Peak demand has hit 245.4 GW (Jan) and 244 GW (Feb), nearing typical summer peaks.
• Electricity demand has increased by ~28% since 2022, indicating a structural rise in consumption.
• Demand is no longer seasonal; both winter (heating) and early summer (cooling) are driving peaks.

Drivers of Power Demand

• Industrial Growth: The industrial sector accounts for nearly 50% of electricity consumption, driving sustained demand.
• 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.

The Fuel Excise Duty Cut

• The Indian government has reduced excise duty on petrol and diesel by ₹10 per litre to shield consumers and Oil Marketing Companies (OMCs) from rising global crude prices.

About The Fuel Excise Duty Cut:

• An excise duty is an indirect tax levied by the Central Government on the manufacture or sale of specific goods within the country.
• In this recent move, the government slashed the duty to ease the financial burden on OMCs, bringing the excise on petrol down to approximately ₹3 per litre and effectively reducing the diesel excise to zero.

How Fuel Prices are Derived in India?

Crude Oil Cost:

• This is the raw material price. Since India imports approximately 85% of its oil, this cost is highly sensitive to global benchmarks (like Brent Crude) and the USD-INR exchange rate.
• A weaker Rupee automatically makes fuel more expensive, even if global oil prices remain flat.

Refinery Transfer Price (RTP):

• Once crude arrives, it must be processed. RTP is the price charged by refineries to Oil Marketing Companies (OMCs).
• It includes the actual cost of refining (turning crude into petrol/diesel), plus ocean freight, insurance, and port charges.

OMC Margin:

• Oil Marketing Companies (like IOCL, BPCL, and HPCL) add an operational margin to cover their own costs.
• This includes the expense of transporting fuel from refineries to storage depots and then to petrol pumps, as well as their corporate overheads and profit.

Central Excise Duty:

• This is a fixed-rate tax levied by the Union Government. Unlike some taxes that are a percentage, this is usually a specific Rupee amount per litre.
• It includes basic duty, the Road and Infrastructure Cess (RIC), and the Agriculture Infrastructure and Development Cess (AIDC).

Dealer Commission:

• This is the earnings paid to the petrol pump owner. It covers the cost of running the station, employee wages, electricity, and the dealer’s profit margin. It is revised periodically by the government.

State VAT (Value Added Tax):

• This is an ad valorem tax (a percentage) imposed by individual State Governments. Because it is a percentage of the sum of all previous costs, the tax amount increases as the base price rises.
• This is why fuel prices vary significantly between states like Goa (lower VAT) and Rajasthan or Maharashtra (higher VAT).

RBI Payments Vision 2028

• The Reserve Bank of India (RBI) has released its ‘Payments Vision 2028’ document, titled Shaping India’s Payment Frontier.

• Interoperability in TReDS and factoring with recourse will unlock much-needed liquidity for small businesses, boosting the Make in India initiative.

Microplastics in Coastal Ecosystems

• 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.
• Microbeads are tiny plastic particles used in personal care products like scrubs and toothpaste.

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).

Natural Mineral Water

• Food Safety and Standards Authority of India (FSSAI) mandated stricter standards and monthly testing for natural mineral water in India.
• Natural mineral water comes from protected underground aquifers or natural springs that contain natural minerals and trace elements.
• Formation: Rainwater seeps through rock layers, dissolving minerals like calcium and magnesium; underground pressure pushes this water towards the surface or into reservoirs.
• Significance: They provide essential micronutrients to bridge dietary gaps without additional calories, support digestion, and maintain electrolyte balance.

Regulatory Framework in India

• BIS Mandate: Natural mineral water must have consistent mineral content across batches, reflecting its geological source (under IS 13428).
• Source Rule: Water must be bottled at the source, and aquifers or springs must be protected from external contamination.
• Treatment Limit: Producers can’t use chemical disinfectants, Reverse Osmosis (RO), or UV light; only physical filtration, decantation, or aeration is allowed.
• FSSAI Mandates: A central license is compulsory; labels must disclose mineral content and origin; making medicinal claims is strictly prohibited.
• Bureau of Indian Standards (BIS), operating under the Ministry of Consumer Affairs, Food and Public Distribution, ensures standards and quality for consumer safety and product reliability.

Inflation Targeting in India Extended till 2031

• The Government has extended the inflation targeting framework for another five years (2026–2031) in consultation with the Reserve Bank of India.
• Target Rate: Maintain retail inflation (CPI) at 4% as the central benchmark.
• Tolerance Range: Allows fluctuation within a 2%–6% band to ensure flexibility in monetary policy.
• India follows Flexible Inflation Targeting (FIT), which balances price stability with economic growth.

Inflation Targeting Framework

• Adopted in 2016 following recommendations of the Urjit Patel Committee (2014).
• Legal Basis: Given statutory backing through the Finance Act, 2016, which amended the RBI Act, 1934.
• Mechanism: Government sets the inflation target (4% ± 2%) in consultation with the RBI. The Monetary Policy Committee (MPC) uses tools like the repo rate to achieve this target.
• Accountability: If inflation exceeds the target range for 3 consecutive quarters, the RBI must report to the government explaining the reasons and corrective steps.
• Evolution: The inflation target of 4% (±2%) was retained in 2021 (till 2026) and extended again for 2026–2031, ensuring policy continuity.

• The report, first launched in 2017, is published by the National Statistics Office (NSO), Ministry of Statistics and Programme Implementation.
• From 2025 onwards, the survey period has been shifted from the agricultural year (July–June) to the calendar year (January–December) along with changes in survey methodology.

PLFS Report

• The report aims to estimate the key employment and unemployment indicators (viz. Labour Force Participation Rate (LFPR), Worker Population Ratio (WPR) and Unemployment Rate (UR)) in both usual status (principal activity status + subsidiary activity status) and Current Weekly Status (CWS).

Key Indicators:

• LFPR: Percentage of persons in the labour force (i.e. working or seeking or available for work) in the population.
• WPR: Percentage of employed persons in the population.
• UR: Percentage of persons unemployed among the persons in the labour force.
• Activity Status – Usual Status: Determined on the basis of the reference period of last 365 days preceding the date of survey.
• Activity Status - CWS: Determined on the basis of a reference period of last 7 days preceding the date of survey.

Key Highlights of the Report

• LFPR:  LFPR for individuals aged 15 years and above remained at 59.3% (male participation- 79.1% and female participation- 40%).
• Among male, 69.8% reported want to continue studies as the main reason for not being in the labour force, whereas among female, 44.4% cited child care/personal commitments in home-making as the main reason.
• WPR: Overall WPR for ages 15 and above is 57.4% (76.6% for males and 38.8% for females).
• UR: UR for persons aged 15 and above was 3.1% (Rural- 2.4% and Urban- 4.8%).
• Share of self-employed persons: Shown a gradual decline from 2023 (58.2%) to 2025 (56.2%).
• Sectoral Employment Changes: Agriculture remains the largest employer, though its share declined from 44.8% in 2024 to 43% in 2025.

Tunguska Air Defence Missile System (2K22M)

• The Ministry of Defence signed a Rs 445 crore contract with Russia’s JSC Rosoboronexport, to procure the Tunguska Air Defence Missile System for the Indian Army.

About Tunguska Air Defence Missile System (2K22M):

• The Tunguska (NATO reporting name: SA-19 Grison) is a Soviet-origin, tracked, self-propelled anti-aircraft weapon system. It is a unique hybrid platform that combines both surface-to-air missiles and high-speed anti-aircraft guns on a single chassis to provide comprehensive protection to ground forces.

Developed By:

• Originally developed by the KBP Instrument Design Bureau in the Soviet Union, the system is currently managed and exported by JSC Rosoboronexport, Russia.

Aim:

• The system is designed to provide low-altitude air defense for infantry and armored regiments. Its main objective is to protect ground troops on the move against low-flying targets, including:
• Attack helicopters and close-support aircraft.
• Cruise missiles and precision-guided munitions.
• Modern tactical drones and Unmanned Aerial Vehicles (UAVs).

Key Features:

• It strengthens India’s multi-layered air defense network, acting as a vital shield for mobile army columns that are vulnerable to sudden aerial strikes.

Israeli on Iranian Nuclear Facilities Strikes

• Israel has significantly escalated regional tensions by launching direct airstrikes on two of Iran’s critical nuclear sites, the Khondab Heavy Water Complex and the Ardakan yellowcake plant.

About Israeli Strikes on Iranian Nuclear Facilities:

• The operation involved precision Israeli Air Force strikes targeting the upstream components of Iran’s nuclear fuel cycle. Unlike previous sabotage or cyber-attacks, these kinetic strikes aimed to halt Iran’s ability to produce both weapons-grade plutonium and the concentrated uranium needed for enrichment

Targeted Facilities:

1. Khondab Heavy Water Complex

• Location: Near Arak, Central Iran.
• Features: This facility houses a heavy water production plant and a research reactor. Heavy water is a critical moderator used in reactors that can produce plutonium as a by-product.
• IDF Allegation: The military claimed Iran was rebuilding the site to bypass international commitments to convert the reactor into a non-plutonium-producing configuration.

      2. Ardakan Yellowcake Production Plant

• Location: Yazd Province, Iran.
• Features: This is Iran’s only facility of its kind. It processes uranium ore into yellowcake (U3O8), a concentrated powder that serves as the raw material for uranium enrichment.
• Current Status: Iran’s Atomic Energy Organisation confirmed the hit but noted that, similar to Arak, there were no reported radioactive leaks or casualties at this specific site.

Implications:

• Strikes on yellowcake and heavy water facilities disrupt key inputs, delaying Iran’s fuel production by months/years.
• Breaks the shadow war, raising risk of wider conflict involving proxies like Hezbollah and Houthis, and possible direct retaliation.
• No immediate radiation leak reported, but attacks on nuclear-linked sites heighten accident risks; concerns flagged by Rafael Grossi.

SRY Gene Screening

• The International Olympic Committee (IOC) announced a seismic policy change mandating SRY gene screening for all female athletes in international elite sports.
• This decision effectively bans transgender women and many DSD (Differences in Sex Development) athletes from female categories.

About SRY Gene Screening:

• SRY stands for ‘Sex-determining Region Y’. It is a specific segment of DNA usually found on the Y chromosome. This gene acts as a biological master switch that triggers the development of testes and the production of male levels of testosterone, leading to male physical development.
• Developed By: The SRY gene was first discovered in 1990 by Professor Andrew Sinclair.

Aim:

• The primary objective is to protect the female category in elite sports.
• The IOC aims to ensure that athletes competing in the female category do not have the physiological advantages associated with male puberty and male chromosomal development, such as increased bone density and explosive muscle power.

How it Works?

• Sample Collection: The athlete provides a simple saliva sample or a cheek swab at a certified diagnostic lab.
• DNA Analysis: The lab analyzes the sample to detect the presence or absence of the SRY gene.
• Turnaround Time: The process typically takes about one week for results to be issued.
• Verification: The results are submitted to the relevant international sports body. If negative, the athlete is permanently cleared for the female category.

Key Features:

• Once-in-a-Lifetime: Since the SRY gene is fixed at birth, the test is generally required only once in an athlete’s career.
• Predictive Marker: The IOC views the gene as a highly accurate indicator of whether an athlete has experienced or will experience male sex development.
• Selective Application: It applies only to elite-level international athletes (Olympics, World Championships) and not to grassroots or leisure sports.
• Exceptions for Rare DSDs: Athletes with specific conditions like Complete Androgen Insensitivity Syndrome (CAIS)—where the body cannot process testosterone—may still be eligible for the female category even if they are SRY-positive.
• Voluntary but Mandatory for Entry: Athletes can refuse the test, but refusal results in immediate disqualification from IOC-sanctioned events.

Significance:

• The IOC cites scientific data showing a 10% to 100% performance advantage for male-developed athletes depending on the sport.
• This marks a major shift from self-identification models to biological/genetic models for gender classification in sports.
• The IOC advises early screening so athletes can make informed decisions about their training and investment in the female category.

Zojila Pass

A tragic avalanche at the high-altitude Zojila Pass, resulted in the death of five individuals and left several others injured or trapped.

About Zojila Pass:

• Zojila is a strategic high mountain pass in the Western Himalayas. Often referred to as the mountain pass of blizzards (though scientifically named after the Tibetan goddess Du-Zhi-lha-mo), it serves as the only terrestrial link between the Kashmir Valley and the high-altitude cold desert of Ladakh.

Location:

• Geography: It is situated at an elevation of approximately 3,580 metres (though some sections reach up to 5,008 metres), making it the second-highest pass on the Srinagar–Leh Highway after Fotu La.
• Administrative Boundaries: It sits on the boundary between the Ganderbal district of Jammu and Kashmir and the Kargil district of Ladakh.
• Connectivity: It connects Sonmarg (Kashmir) to the Dras and Suru valleys, eventually leading to Leh.

History:

• 1948 Indo-Pak War: The pass was a major battleground during the First Kashmir War. It was initially seized by Gilgit rebels/Pakistan forces in 1948.
• Operation Bison: In a historic military feat on November 1, 1948, Indian forces recaptured the pass using tanks. This remains the highest altitude at which tanks have ever operated in combat in world history.
• The Tunnel Era: To overcome the pass’s vulnerability to heavy snowfall and avalanches, the Zoji-la Tunnel (14 km long) is currently under construction. Once finished, it will be the longest bidirectional tunnel in Asia.

Key Features:

• Climatic Extremes: The pass faces extremely harsh winters with temperatures dropping to –44°C, while heavy snowfall (major share of ~2600 mm precipitation) disrupts mobility and increases hazard exposure.
• Geological Sensitivity: Highly avalanche-prone terrain where even sunlight-induced melting destabilizes snow layers, triggering sudden slides and making travel unpredictable.
• Zero Point: A popular high-altitude tourist spot with permanent snow cover, but its heavy footfall combined with fragile terrain makes it vulnerable to disasters.
• Seasonal Blockages: Traditionally closed for ~6 months due to snow accumulation, though efforts by Border Roads Organisation have improved year-round connectivity.

Significance:

• Acts as a crucial supply route for Indian forces deployed in sensitive areas like the Siachen Glacier and along the Line of Actual Control, ensuring operational readiness.
• Serves as the main lifeline for Ladakh, enabling transport of essential goods (fuel, food, medicines) and maintaining civilian life in remote regions.
