1. Why did SEBI ask fund houses to stop ETF inflows?
Subject: Economy
Section: Capital Market
Context:
- Markets regulator Securities and Exchange Board of India (SEBI) has directed mutual fund houses to stop accepting any more inflows in schemes that invest in overseas exchange-traded funds (ETFs), starting April 1, 2024.
More on news:
- SEBI has issued these directions as inflows in these overseas ETFs have come close to the mandated investment limit of $1 billion in foreign ETFs.
- The mutual fund industry has already reached 95 per cent or ($ 950 million) of the $1 billion limit. This is the reason why SEBI has asked mutual funds to temporarily stop accepting money in overseas ETFs
Why is SEBI’s direction to MFs ?
- The capital market regulator has asked asset management companies (AMCs) not to accept funds in mutual fund plans that invest in overseas exchange-traded funds (ETFs) as the upper limit of $1 billion for these investments is close to being breached.
- The regulator has asked to stop fresh inflows in such schemes from April 1.
What is the overall limit for mutual funds to invest in overseas ETFs?
- There is an overall cap of $7 billion set by the Reserve Bank of India (RBI) for fund houses to invest in overseas stocks or mutual funds.
- MFs are also permitted to invest up to $1 billion in overseas exchange traded funds.
- Mutual fund industry has been demanding the RBI to hike the overseas investment limit of $7 billion.
What is an exchange traded fund?
- An ETF, or exchange traded fund, is a marketable security that tracks an index, a commodity, bonds, or a basket of assets like an index fund.
- Unlike regular mutual funds, an ETF trades like a common stock on a stock exchange.
- The traded price of an ETF changes throughout the day like any other stock, as it is bought and sold on the stock exchange.
- The trading value of an ETF is based on the net asset value of the underlying stocks that an ETF represents.
- ETFs typically have higher daily liquidity and lower fees than mutual fund schemes, making them an attractive alternative for individual investors.
- ETFs are considered to be more tax efficient compared to other mutual fund schemes.
- There are mainly five types of ETFs – equity ETF, bonds ETF, commodity ETF, international ETF and sectoral/thematic ETF.
2. Hong Kong lawmakers pass new national security law, giving government more power to curb dissent
Subject: Economy
Section: Capital Market
Context:
- Hong Kong lawmakers passed a new national security law on Tuesday that grants the government more power to quash dissent, widely seen as the latest step in a sweeping political crackdown that was triggered by pro-democracy protests in 2019.
More on news:
- The legislature passed the Safeguarding National Security Law during a special session on Tuesday.
- It comes on top of a similar law imposed by Beijing four years ago, which has already largely silenced opposition voices in the financial hub.
- Hong Kong’s Legislative Council, which is packed with Beijing loyalists following an electoral overhaul, expedited the process.
About the law:
- The law threatens stringent penalties for a wide range of actions authorities call threats to national security, with the most severe — including treason and insurrection — punishable by life imprisonment.
- Lesser offenses, including the possession of seditious publications, could also lead to several years in jail.

3. Kerala challenges withholding of Presidential assent to State bills in Supreme Court
Subject: Polity
Section: Parliament and Legislature
Context:
- In an unprecedented move, the Kerala Government on March 23 filed an appeal in the Supreme Court as President Droupadi Murmu has withheld assent for four Bills passed by the Kerala Legislature without disclosing any reasons.
More on news:
- It has also moved the Court against Kerala Governor Arif Mohammed Khan’s office for keeping the Bills pending for a long and indefinite period, and later reserving them for the consideration of the President.
- The act of the President in withholding the assent for the four Bills without giving any reason was highly arbitrary and in violation of Articles 14, 200 and 201 of the Constitution.
- The reference of the seven Bills to the President has to be recalled on the grounds of Constitutional morality.
State Government’s views:
- The State contends that the actions of the Union Government in advising the President to withhold assent to Bills passed by the Legislative Assembly 11 to 24 months back, which were wholly within the domain of the State Government, subverted and disrupted the federal structure of the Constitution.
- It was also a grave encroachment into the domain entrusted to the State under the Constitution.
Reservation of Bills under Article 201:
Article 201 (Bills reserved for consideration)
- When a Bill is reserved by a Governor for the consideration of the President, the President shall declare either that he assents to the Bill or that he withholds assent therefrom.
- Notably, there is no specified timeframe for the President to decide on the Bill’s outcome.
- Provided that, where the Bill is not a Money Bill, the President may direct the Governor to return the Bill to the House or, as the case may be, the Houses of the Legislature of the State together with such a message as is mentioned in the first provision to Article 200.
- When a Bill is so returned, the House or Houses shall reconsider it accordingly within a period of six months from the date of receipt of such message and, if it is again passed by the House or Houses with or without amendment, it shall be presented again to the President for his consideration.

The issue has garnered political and social attention, especially concerning criticisms of the social reformer E V R Periyar.
Details:
- Controversy Over Periyar:
- The controversy gained political dimensions when singers Ranjani and Gayathri withdrew from the December music season, citing Krishna’s praise of Periyar—who they inaccurately alleged advocated for genocide—as a reason. This led to public backlash and discussions about Periyar’s views on equality and women’s rights.
- Defense of Periyar: Both M K Stalin and DMK MP Kanimozhi Karunanidhi defended Periyar’s legacy, emphasizing his lifelong dedication to social reform, equality, and women’s rights. They argued that a proper understanding of Periyar’s work would counteract the criticism.
- Broader Implications:
- This controversy reflects the broader tensions in Tamil Nadu and Indian society between cultural appreciation and political ideologies, especially in the context of caste and social reform.
- It underscores the challenges of maintaining cultural spaces free from political disputes and highlights the ongoing relevance of Periyar’s legacy in contemporary debates.
About E V Ramasamy ‘Periyar’:
- Born in 1879, E V Ramasamy ‘Periyar’ is remembered for the Self Respect Movement to redeem the identity and self-respect of Tamils.
- Periyar started his political career as a Congress worker. He quarrelled with Gandhi over the question of separate dining for Brahmin and non-Brahmin students.
- He resigned from the party in 1925, and associated himself with the Justice Party and the Self Respect Movement, which opposed the dominance of Brahmins in social life, especially the bureaucracy.
- Periyar’s fame spread beyond the Tamil region during the Vaikom Satyagraha of 1924, a mass movement to demand that lower caste persons be given the right to use a public path in front of the famous Vaikom temple. He would later be referred to as VaikomVeerar (Hero of Vaikom).
- In the 1940s, Periyar launched a political party, DravidarKazhagam (DK), which espoused an independent Dravida Nadu comprising Tamil, Malayalam, Telugu, and Kannada speakers.
- As a social reformer, he focused on social, cultural and gender inequalities, and his reform agenda questioned matters of faith, gender and tradition.
- Periyar died in 1973 at the age of 94. Over the years, Periyar is revered as Thanthai Periyar, the father figure of modern Tamil Nadu.

- 2024 Theme: The theme for World Meteorological Day 2024 is “At the frontline of climate action,” reflecting urgent climate, weather, and water-related issues.
Global Greenhouse Gas Watch Programme (G3W):
- It is a new greenhouse gas (GHG) monitoring initiative of the World Meteorological Organisation (WMO).
- G3W will fill critical information gaps, providing an integrated, operational framework under all space-based and surface-based observing systems under one roof, along with modelling and data assimilation capabilities.
- It will build on WMO’s experience in coordinating international collaboration in predicting the weather and analysing climate on long-standing activities in greenhouse gas monitoring and research under the guidance of the Global Atmosphere Watch, established in 1989.
- G3W predicts a top-down approach to the flux evaluation, which builds on existing capabilities in surface- and space-based observations and modelling, ensuring the timely exchange of all observations and data.
- The G3W will consist of four main components:
- Comprehensive, sustained, global surface- and satellite-based observations of CO2, methane, and nitrous oxide concentrations, partial column amounts, total column amounts, vertical profiles, and fluxes supporting oceanic, meteorological, and terrestrial variables, internationally exchanged as rapidly as possible.
- Prior estimates of the GHG emissions based on the activity data and process-based models.
- Global high-resolution Earth system models representing GHG cycles.
- Data assimilation systems combining the observations with model calculations to generate products of higher accuracy.
“Early Warnings for All” Initiative:
- The “Early Warnings for All” initiative is a groundbreaking effort to ensure that everyone on Earth is protected from hazardous weather, water, or climate events through life-saving early warning systems by the end of 2027.
- Project partners:
- The Early Warnings for All initiative is co-led by the World Meteorological Organization (WMO) and the United Nations Office for Disaster Risk Reduction (UNDRR), with support from the International Telecommunication Union (ITU) and the International Federation of Red Cross and Red Crescent Societies (IFRC) and other partners.

10. Activist write to pm highlighting shortage of vital anti-TB drug
Subject: Science and tech
Section: Health
About the news:Activist, Public health experts and survivors wrote a letter PM ahead of World tuberculosis day (24th March) request urgent intervention to address the shortage of Anti-TB Drug
- Letter also highlight shortage of drug essential for treating drug sensitive (DS-TB)
- Till february shortage of 1st line Drug Isoniazid, Rifampicin, Pyrazinamide, Ethambutol drugs
Why Shortage of Drug: Unavailability due to lack of demand in the open market
How Shortage will Impact India:
- Highest burden of TB in the world and shortage of critically required drug affects to treat patient
- According to Nationally TB Elimination Program (NTEP) uninterrupted supply of quality drug is essential for Directly observed Therapy Short Course (DOTS)
- Inadequate access to quality TB Drug may cause emergence of Drug Resistance variety of TB strain which is very difficult and costly to treat
- This Shortage Poses a significant risk to the survivor of Multidrug Resistant TB
- Affects treatment outcomes like India pledge to eliminate TB by 2025
TB Burden of India as per global TB report 2023:
- Highest burden of TB in the world 2.8 million that is 27% of TB burden
- Case fatality ratio 12% (out of 100 TB cases 12 case resulted into death)
- India having 1.1 lakh of Multidrug TB (MDR-TB)
Step Taken by India to tackle TB problem:
- PM TB Mukt Bharat Abhiyaan: To bring together all community stakeholder to support those on TB treatment and accelerate the country progress towards TB elimination
- New Drug like Bedaquiline and Delamanid made available for treatment of Drug resistant TB
- National TB Control Program: Anti-TB Drug are procured and supplied to various states and then distributes to various states
- Nikshay Poshan: Direct benefit transfer of Rs 500 to TB patient/month for nutrition
- Universal drug susceptibility test to ensure every diagnosed TB patient is tested to ruled out drug resistance
Different Type of TB
- Multidrug Resistance TB (MDR-TB) : TB which is resistance to 1st line anti-TB drug, it is developed when course of antibiotics is interrupted and can be treated with second line antibiotics Drug
- Extensive Drug Resistance TB (XDR-TB):Caused by strain that is resistance to both firstline and second line antibiotics
- Totally Drug Resistant TB (TDR-TB):It is a form of Tuberculosis which is resistant to all currently used drug
11. Anaemia prevalence in eight states found to be overstated
Subject: Science and tech
Section: Health
Why in news: Study across 8 states found that prevalence of Anaemia has been overestimated by previous National family Health survey (NFHS-5)
More about News:
- NFHS Survey measured the hemoglobin using finger prick based capillary blood, these methods underestimate the true blood cells count in capillary blood than venous blood methods
- This lower reading of Haemoglobin due to tissue fluid get mixed with capillary blood while drawing the blood samples leading to dilution thus lower reading of Haemoglobin
Finding of study:
Assam is highest Anaemia prevalence 69% (78.3% Women) and lowest Meghalaya 12.1 % (14.6% for women)
The Iron Deficiency for whole group was just 18.4% , only 25% of women anaemic women(42%) have iron deficiency
Biased in treatment :
- Thoughanaemia is caused by multiple factors like vitamin B 12 and folate deficiency and inflation
- But it is generally believed Iron deficiency as cause of anaemia so focus primarily on treatment of iron deficiency
- Danger of excess iron intake cause oxidative stress on all organs as it is not easy to excrete
Way forward:
- Focus should be on reducing inflammation by consumption of fruits and vegetables
- Diversifying diets to improve intake of all nutrients
- With climate change the nutritional content in cereal decline so we need to diversify from cereal to millets
Anaemia Mukt Bharat
Anaemia Mukt Bharat strategy is focused on benefitting six target beneficiary groups, through six interventions and six institutional mechanisms to achieve the envisaged target of anaemia reduction under the POSHAN Abhiyaan.
Key highlights of the strategy
- Provision of supervised biweekly iron-folic acid(IFA) supplementation by the ASHA for all under-five children
- Weekly IFA supplementation for 5-10 years old children
- Annual/biannual deworming (children and adolescents)
- Point of care testing(POCT) and treatment for in-school adolescents and pregnant women using newer technologies
- Establishing institutional mechanisms for advanced research in anaemia
- Addressing non-nutritional causes of anaemia and
- Setting a comprehensive communication strategy including mass/mid media/social media communication material (radio and TV spots, posters, job-aids, interpersonal communication material
12. Dispersal out of Africa may have occurred during arid period
Subject: History
Section: Msc
Why in news: Recent Study Published in the Journal Nature suggest the most recent widespread migration of human out of Africa takes place less than 1,00,000 years, may have taken place during Arid period following Toba super volcano eruption in Indonesia
More About News:
- It was earlier believed that dispersal of Human out of Africa occurred during Humid period as it creates a Green corridor and facilitates the movement of people
- Period of Aridity are thought to have constrained human movement and creates food insecurity
New Evidence in support:
- Near Shinfa River Evidence Human presence in the form of Chipped stone from tool manufacturing and Animal remains and chemical analysis of Glass Shards found they were from Toba Super eruption (74000 years ago)
- Evidence from Ostrich Egg-Shells and fossil mammal teeth indicates that the environment at that time was particularly Arid
New Finding:
- With Increasing AridityRiver Shrank in the dry season so fish were trapped easily in water holes by using bow and arrows
- Adaptive Forage along with Dry season Waterhole would have transformed seasonal river into blue highways , potentially facilitating out-of Africa dispersal
- Behavioral flexibility documented at this site helped these humans to survive aftermath of the super eruption and may play critical role for modern human to prosper in the diverse climates and habitats across the world
