Online Gaming Under the PMLA
Syllabus: GS2/ Governance
Context
- The Union government has proposed the classification of online real-money gaming firms as “reporting entities” under the Prevention of Money Laundering Act (PMLA) of 2002.
About
- Under the PMLA, a reporting entity is required to provide client and transaction information to the Financial Intelligence Unit-India (FIU-IND), which is under the purview of the Ministry of Finance.
- Earlier, the government had imposed a 28% Goods and Services Tax (GST) on the full deposits made by users on real-money gaming platforms in 2023.
Gaming Industry in India

Discovery of Small Hive Beetle in India
Syllabus :GS 3/Environment
In News
- A scientist from the Zoological Survey of India (ZSI), identified the Small Hive Beetle (SHB), Aethina tumida, in Amdanga, West Bengal.
- This is the first recorded instance of SHB in India.

Small Hive Beetle
- SHBs are small, oval-shaped beetles (5-7 mm), reddish-brown in color.
- It is a notorious enemy of honey bees and has caused widespread damage to the apiculture industry globally.
- It infiltrates hives, laying eggs that hatch into larvae, which feed on honey, pollen, and bee brood, contaminating honey and causing colony collapse.
- Distribution : Originating in sub-Saharan Africa, SHB has spread globally to the United States, Australia, Canada, and parts of Asia.
- India’s climate may favor the proliferation of SHB, making early detection and response crucial.
- Classifications: It is classified as an “Invasive Alien Species,” a category of non-native organisms that pose significant threats to biodiversity and local ecosystems.
- The World Organisation for Animal Health (OIE) has classified SHB infestation as a notifiable disease due to its destructive potential.
Concerns
- The presence of SHB raises concerns about its impact on India’s honey bee population and apiculture industry. The beetle is known for rapidly multiplying and spreading.
- SHB could harm India’s beekeeping sector, jeopardizing honey production and the livelihoods of those dependent on it.
Measures to tackle them
- Experts emphasize the need for coordinated monitoring, containment strategies, and awareness campaigns to protect native pollinators and the apiculture industry in India.

Volatility Index (VIX)
Syllabus :GS 3/Economy
Context
- Recently, The India Volatility Index surged over 65% to 22.8, marking its highest single-day spike ever, indicating heightened risk and uncertainty in the market.
Volatility Index (VIX)
- The term “VIX” is a trademark owned by the Chicago Board Options Exchange (CBOE).
- It measures the market’s expectation of volatility over the near term, reflecting the rate and magnitude of price changes, often associated with risk.
- It is calculated as annualized volatility, expressed as a percentage, based on the order book of options for a specific underlying index.
India VIX
- It is specifically based on NIFTY Index Option prices.
- It calculates the expected market volatility for the next 30 days by analyzing the best bid-ask prices of NIFTY Options contracts.
- India VIX uses the CBOE’s computation methodology, with adjustments made for the NIFTY options order book, incorporating techniques like cubic splines.
Latest Updates
- The recent increase was driven by a sharp 5% sell-off in Indian equities, sparked by concerns over the impact of US President Donald Trump’s tariffs and China’s retaliatory measures.
- The spike in volatility is reminiscent of previous global market turmoil, such as in August 2015.

“Blue Category” Classification For Industries
Syllabus :GS 3/Economy
In News
- The Central Pollution Control Board (CPCB) has introduced a new “Blue Category” in its industrial classification system, aimed at recognizing and incentivizing essential environmental service industries.
Revised classification for industries
- The Blue Category was created under the “precautionary principle,” based on the potential environmental impact of industries.
- The Blue Category includes industries such as Waste-to-energy plants, some compressed biogas (CBG) plants, and other utilities involved in managing environmental concerns (e.g., waste management).
- These industries, although potentially high on the Pollution Index (PI), are recognized for their positive environmental externalities.
- Industries classified under the Blue Category will receive an additional two years of validity for their Consent to Operate (CTO), based on their Pollution Index (PI).
Pollution Index-Based Classification
CPCB classifies industries based on their pollution potential (PI):

For Example: Waste-to-energy plants are included in the Blue Category due to their essential role despite their high pollution potential.
About Central Pollution Control Board (CPCB) – It is a statutory organization under the Ministry of Environment, Forest and Climate Change (MoEF&CC) in India. – CPCB was entrusted with the powers and functions under the Air (Prevention and Control of Pollution) Act, 1981. – It serves as a field formation and also provides technical services to the Ministry of Environment and Forests of the provisions of the Environment (Protection) Act, 1986. |

Centre for Research on Energy and Clean Air (CREA) Report on Air Pollution
Syllabus: GS3/Environment
Context
- A new analysis by non-profit Centre for Research on Energy and Clean Air (CREA) revealed data on India’s Air Pollution levels.
Key Points:
- Delhi’s PM 10 Levels: Delhi recorded the highest Particulate Matter 10 levels among 130 cities under the National Clean Air Programme (NCAP) in FY 2024-25.
- Delhi’s annual average PM 10 concentration was 206 µg/m³, three times above the national standard of 60 µg/m³.
- Other Cities with High PM 10 Levels: Byrnihat (Assam) and Patna (Bihar) followed Delhi.
- NCAP Targets: The NCAP aims to reduce PM 10 levels by up to 40% by 2025-26 compared to the 2017 baseline.
- PM 10 reductions are assessed on a financial year basis.
- Improvements and Declines: 77 cities showed improvements in PM 10 levels compared to 2017-18.
- 23 cities saw increases in PM 10 levels, and 2 cities had unchanged levels.
- Cities with Over 40% Improvement: 21 cities, especially from Uttar Pradesh, showed over 40% improvement, including Bareilly, Varanasi, and Kanpur.
- Cities with Increased PM 10 Levels: Cities with a rise in PM 10 levels include Maharashtra, Odisha, Assam, Madhya Pradesh, Bihar, West Bengal, and Chhattisgarh.
- Significant Changes:
- Bareilly (Uttar Pradesh) showed the largest reduction in PM 10 levels at 78%.
- Jalgaon (Maharashtra) recorded the highest increase in PM 10 levels at 57%.
- Ongoing Challenges: Despite improvements, 91 of the 102 NCAP cities still exceeded the national PM 10 standard during FY 2024-25, with just one year left to meet NCAP targets.
