Banking Sector Reforms

Why US Fed cut interest rates, how India could be impacted? 

Note4Students

From UPSC perspective, the following things are important :

Mains level: Implications of Global Markets on India; Implication of interest rate;

Why in the News?

The United States Federal Reserve, responsible for the country’s monetary policy, announced on Wednesday that it will lower its key interest rate, called the Federal Funds Rate, by 0.5%, or 50 basis points.

Why did the Fed cut interest rates?

  • The Federal Reserve cut the benchmark interest rate by 50 basis points to address rising unemployment concerns while inflation was stabilizing.
  • After a series of aggressive rate hikes to counter inflation that surged due to post-COVID recovery and the Russia-Ukraine war, inflation began to moderate, nearing the Fed’s target of 2%.
  • Rising unemployment data signaled that the restrictive monetary policy might harm the labor market, prompting the Fed to act.

Will the US economy achieve a soft landing?

  • Optimistic Projections: Despite earlier predictions that high inflation would lead to a recession, the Fed’s strategy may succeed in achieving a soft landing, reducing inflation without crashing the economy.
  • GDP Growth: The Summary of Economic Projections (SEP) estimates GDP growth to remain around 2% for the next few years, indicating a stable economy.
  • Unemployment: While the unemployment rate has risen slightly to 4.4%, it remains manageable, with expectations of improvement.
  • Risks: Potential policy shifts, especially related to the upcoming presidential election, could disrupt the economic outlook, particularly if trade tariffs are imposed.

How will India be affected?

  • Increased Foreign Investments: Lower US interest rates could encourage foreign investors to borrow in the US and invest in India through stocks, bonds, or foreign direct investment (FDI), benefiting capital inflow.
  • Rupee Strengthening: With falling US interest rates, the US dollar may weaken against the Indian rupee, potentially strengthening the rupee. This would negatively affect Indian exporters but benefit importers.
  • RBI’s Interest Rate Decisions: While the Fed’s rate cuts influence global markets, India’s central bank, the RBI, may not directly follow suit due to differing inflation targets and mandates. The RBI prioritizes inflation control and GDP growth over unemployment figures.

Way forward: 

  • Encourage Capital Inflows: India should take advantage of lower US interest rates by attracting foreign investments through improved ease of doing business, fostering growth in key sectors like infrastructure, technology, and manufacturing.
  • Maintain Monetary Stability: The RBI should carefully assess global trends but prioritize domestic conditions when adjusting interest rates, focusing on inflation control, financial stability, and sustained GDP growth.

Mains PYQ:

Q Do you agree with the view that steady GDP growth and low inflation have left the Indian economy in good shape? Give reasons in support of your arguments. (UPSC IAS/2016)

Amoebic Meningoencephalitis

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Primary Amoebic Meningoencephalitis (PAM); Naegleria fowleri.

Why in the News?

    • This year, Kerala faced a sudden surge in Amoebic Meningoencephalitis cases, caused by free-living amoebae (FLA) found in freshwater ponds, lakes, and rivers.
  • Kerala also saw a diverse range of amoebic infections, caused by Naegleria fowleri, Vermamoeba vermiforis, and Acanthamoeba.

What is Primary Amoebic Meningoencephalitis (PAM)?

  • PAM is caused by the Naegleria fowleri, often referred to as the “brain-eating amoeba“. It destroys brain tissue, causing severe swelling and is fatal in most cases.
    • An amoeba is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods.
    • Higher temperatures of up to 115°F (46°C) are conducive to its growth and it can survive for short periods in warm environments.
  • The amoeba enters the body through the nose, typically during activities like swimming, and travels to the brain, causing severe damage.
  • PAM is also non-communicable.
  • Symptoms: Headache, fever, nausea, vomiting, stiff neck, confusion, seizures, hallucinations, and coma.
    • According to the US Centers for Disease Control and Prevention (CDC), most people with PAM die within 1 to 18 days after symptoms begin. It usually leads to coma and death after 5 days.

Diagnosis and Treatment:

  • Currently, there are no established effective treatments for PAM.
  • Diagnosis involves PCR tests of cerebrospinal fluid, though detection can be challenging due to the rarity of PAM.
  • Treatment follows CDC guidelines, including miltefosine, Azithromycin, and Amphotericin B, with miltefosine recently procured by the State Health Department from Germany.
    • Medical interventions typically involve a combination of drugs, including amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone.

One Nation, One Election: Prospects and Challenges

Simultaneous polls plan gets Union Cabinet nod

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Simultaneous election; One Nation One Election;

Mains level: Federalism

Why in the News?

The Union Cabinet accepted the Kovind committee’s recommendations for simultaneous Lok Sabha and State Assembly elections, with municipal and panchayat polls within 100 days.

What are the recommendations given by the Kovind Panel?     

  • The panel recommended holding simultaneous elections for the Lok Sabha and State Assemblies as a first step, followed by municipal and panchayat polls within 100 days of the general election.
  • The President would issue a notification setting an “Appointed Date” to mark the start of the new electoral cycle. All State Assemblies formed after this date would conclude their terms before the next general election.
  • The panel recommended amendments to Article 83 (duration of Parliament) and Article 172 (duration of State Legislatures) to account for scenarios like a hung assembly or no-confidence motion.
  • A single electoral roll for Lok Sabha, State Assemblies, and local bodies was proposed to streamline the election process, requiring coordination between the Election Commission of India (ECI) and State Election Commissions (SECs).
  • The panel suggested 18 amendments to synchronize elections, most of which do not require ratification by State Assemblies but will require a two-thirds majority in both Houses of Parliament.

Significance of Simultaneous Polls:

  • Cost Efficiency: Holding simultaneous elections is expected to reduce the financial burden by cutting down on the repetitive cost of conducting separate elections.
  • Increased Governance Efficiency: Simultaneous polls would allow governments to focus on governance rather than being in continuous election mode.
  • Reduced Electoral Fatigue: Voters and political parties will face fewer disruptions caused by the constant election cycle, leading to more stable and efficient governance.
  • Economic Benefits: By reducing the frequency of elections, resources can be allocated more effectively toward development and economic growth.

What do the critics say?

  • Impracticality in a Federal Setup: Critics, including the Congress president, argue that simultaneous elections undermine federalism and the autonomy of State legislatures, which may need to dissolve at different times.
  • Constitutional Hurdles: Critics emphasize that the changes required would demand significant amendments to the Constitution and may face legal and political challenges, including garnering the required majority in Parliament.
  • Logistical Concerns: Managing elections for both national and local bodies across a large and diverse country like India would pose logistical difficulties.
  • Impact on Democracy: Some fear that simultaneous polls may result in the overshadowing of local issues by national politics, potentially harming the representation of state-specific concerns.

Way forward: 

  • Consensus Building and Pilot Implementation: Gradually introduce simultaneous elections by building political consensus through consultations with state governments and stakeholders, and consider a phased implementation, starting with a few states as a pilot.
  • Strengthening Electoral Framework: Enhance coordination between the Election Commission of India (ECI) and State Election Commissions (SECs), and ensure legal reforms such as the creation of a unified electoral roll and addressing potential challenges like a hung assembly through constitutional safeguards.

Foreign Policy Watch: India-Pakistan

India to Freeze Negotiations with Pakistan on Indus Treaty  

Note4Students

From UPSC perspective, the following things are important :

Mains level: Effectiveness of Indus Treaty for India;

Why in the News?

The Permanent Indus Commission meetings are on hold until India and Pakistan talk about updating the 64-year-old Indus Water Treaty. The last meeting took place in May 2022.

What is the Indus Treaty?

  • The Indus Waters Treaty (IWT), signed on September 19, 1960, is a water-sharing agreement between India and Pakistan, mediated by the World Bank.
  • The treaty allocates the waters of the Indus River system, which includes three eastern rivers (Ravi, Beas, and Sutlej) to India and three western rivers (Indus, Chenab, and Jhelum) to Pakistan.
  • This framework was established to manage the sharing of water resources in a region where water scarcity is a significant concern due to agricultural demands and population growth.

Features of Treaty: 

  • Permanent Indus Commission: The treaty established the Permanent Indus Commission, which consists of representatives from both nations tasked with resolving disputes and facilitating communication regarding water management.
  • Dispute Resolution: The treaty includes mechanisms for dispute resolution, allowing for consultation with neutral experts or arbitration through international courts if disagreements arise.

Why did the Indian government opt to modify and review the Treaty?

  • Changed Demographics: India emphasizes that significant changes in population demographics necessitate a reassessment of water-sharing obligations under the treaty.
  • Environmental Considerations: The need to accelerate clean energy development (Hydro power electricity) to meet emission targets has been highlighted as a reason for modifying the treaty’s provisions, reflecting broader environmental concerns.
  • Security Issues: Persistent cross-border terrorism has been cited as a factor undermining India’s ability to utilize its rights under the treaty fully.
  • Perceived Imbalance: Analysts in India have described the treaty as “one-sided,” arguing that it disproportionately favors Pakistan given India’s larger population and growing water needs.
    • They believe India’s leverage over western rivers should be enhanced, especially during heightened tensions.

Way forward: 

  • Renegotiation of Terms: India and Pakistan should engage in bilateral talks to update the Indus Waters Treaty, reflecting modern challenges like demographic changes, energy needs, and security concerns, while ensuring fair water distribution.
  • Enhanced Cooperative Framework: Strengthen the role of the Permanent Indus Commission by introducing regular environmental and security assessments, and improving communication to prevent conflicts and ensure sustainable water management.

Ammonium Nitrate imports cause concern                                                                       

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Ammonium Nitrate

Why in the News?

  • Ammonium Nitrate (AN) imports from Russia have sharply increased affecting domestic fertilizer companies in India.
    • The import of Ammonium Nitrate is concerning due to increased dependence on foreign supply, price disparity impacting domestic industries, and potential risks to national energy and security.

What is Ammonium Nitrate?

  • Ammonium Nitrate (NHNO) is a nitrogen-rich, white, crystalline chemical compound.
  • It is soluble in water and commonly used in various industries.
  • Uses:
    • It is widely used as a fertilizer in agriculture.
    • It serves as a component for anaesthetic gases and cold packs.
    • It is also a key ingredient in commercial explosives used for mining and construction.
  • Ammonium nitrate is classified as an oxidizing substance under Grade 5.1 by the United Nations.
  • India’s Regulations:
    • AN is regulated under The Ammonium Nitrate Rules, 2012, and its manufacture or use requires a license.
    • The Explosives Act, 1884 defines ammonium nitrate as any compound with more than 45% AN by weight.
    • Storage Restrictions: Storing large quantities of AN in populated areas is illegal in India.
    • For manufacturing, companies need an industrial license under the Industrial Development and Regulation Act, 1951.

Why is it a Cause of Concern?

  • Ammonium Nitrate is a primary component in explosive mixtures like ANFO (Ammonium Nitrate Fuel Oil).
  • Though not explosive on its own, it becomes highly dangerous when mixed with detonators like RDX or TNT.
  • It has been used in Improvised Explosive Devices (IEDs) by terrorist groups.
  • Accidents involving AN, like the Beirut port explosion in 2020, have raised serious concerns about its storage and handling.
  • Its widespread use in fertilizers leads to concerns about environmental impact, especially when mishandled.
  • Improper storage in populated areas can result in devastating accidents, which is why stringent regulations are in place to control its use, storage, and transport.

PYQ:

[2015] What can be the impact of excessive/inappropriate use of nitrogenous fertilizers in agriculture?

J&K – The issues around the state

Nature of J&K Assembly

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Jammu and Kashmir;

Mains level: Democratic Governance; Significance of Assembly Election;

Why in the News?

The ongoing first phase of polling for the J&K Assembly significantly marks the first assembly election since 2019’s (Article 370 abrogation), resulting in a fundamentally changed Assembly.

Structural changes made during the J&K Reorganisation Act of 2019:

  • Statehood to Union Territory: The Act downgraded Jammu and Kashmir from a state to a Union Territory (UT) with a legislature, while Ladakh became a UT without a legislature.
  • Abrogation of Article 370: The special status granted under Article 370 was removed, extending the Indian Constitution and laws to Jammu and Kashmir in their entirety.

Importance of Election in Jammu and Kashmir:

  • Restoration of Democratic Governance: After the abrogation of Article 370 in 2019, Jammu and Kashmir lost its statehood and was reorganized as a Union Territory. Elections are crucial to restore democratic governance and allow people to elect their representatives.
  • Political Representation: The elections offer citizens the opportunity to choose their leaders and voice their concerns, ensuring political representation at a regional level within the framework of the Union Territory.
  • Restoring Normalcy and Stability: Conducting elections in the region is seen as a step toward restoring political stability and normalcy after a period of uncertainty and tension following the constitutional changes in 2019.

Powers of the J&K Assembly:

  • Legislative Powers: The J&K Legislative Assembly can make laws on subjects in the State List, except for public order and police, which are under the LG’s jurisdiction. It can also legislate on subjects in the Concurrent List, provided the laws are not repugnant to central legislation.
  • Financial Bills: Any financial bill or amendment in J&K requires the prior recommendation of the LG before being introduced in the Assembly. This ensures that significant financial decisions are under the control of the central government.

Powers of the Lieutenant Governor of J&K:

  • Discretionary Powers: The LG has the authority to act independently on subjects outside the Assembly’s purview, such as public order, police, bureaucracy, and the Anti-Corruption Bureau.
  • Final Authority: The LG’s decisions on whether a subject falls under his discretion are final and cannot be challenged in court. This gives the LG significant control over governance in the UT.
  • Appointment Powers: The LG has the power to appoint the Advocate General, law officers, and approve prosecutions, further enhancing his administrative role.

Conclusion: The structural changes in Jammu and Kashmir post-2019 have reshaped its governance, enhancing the Lieutenant Governor’s powers. Elections are essential for restoring democratic representation, ensuring regional participation, and promoting stability after the abrogation of Article 370 and state reorganization.

Russian Invasion of Ukraine: Global Implications

Power asymmetry between China and Russia

Note4Students

From UPSC perspective, the following things are important :

Mains level: Impact of deepening Russia-China relations;

Why in the News?

Due to sanctions put by the USA, affected Russia’s usual supply and pressured its domestic production eventually led to  China’s share of Russia’s imports surged from 32% in 2021 to 89% in 2023.

What is the issue over the dual hegemony of the dollar and the SWIFT messaging system? 

  • Effect of Ukraine War: Following Russia’s invasion of Ukraine in 2022, the U.S. and its allies froze $300 billion of Russia’s foreign exchange reserves and imposed a SWIFT ban on Russian banks involved in dual-use goods. This showed the weaponization of the U.S.-led financial system.
  • China’s Fears: China, with about $770 billion of its reserves held in U.S. treasuries, fears similar financial penalties if tensions with the West escalate.
  • Dual Hegemony: Both Russia and China share concerns over the dominance of the U.S. dollar in global transactions and the influence of the SWIFT (Society for Worldwide Interbank Financial Telecommunication) system, which is integral to cross-border payments.
    • Both countries have tried to de-dollarize their economies and promote alternative payment systems like China’s Cross-Border Interbank Payment System (CIPS).
    • However, CIPS is still far from challenging the dominance of SWIFT, and their efforts to create alternative financial frameworks have not seen significant global success.

About SWIFT system:

  • Founded in Belgium (1973), SWIFT is overseen by the G-10 central banks.
  • The SWIFT system is a global financial messaging system used by banks and financial institutions to send and receive information about financial transactions securely.
  • Russia and China have both developed alternative systems to SWIFT.

What is the issue over the dual hegemony of the dollar and the SWIFT messaging system? 

  • Trade Dependence: Russia has a minor trade surplus with China, but the trade relationship is imbalanced: China represents 30.4% of Russia’s exports and 36% of its imports, while Russia is only 3% of China’s exports.
  • Energy Dominance: Over 70% of Russia’s exports to China are fossil fuels, making it vulnerable to changes in China’s energy needs.
  • High-priority goods: In 2023, 89% of Russia’s high-priority goods were imported from China, compared to 32% in 2021.

What does it mean for India?

  • Strategic Implications: The deepening partnership between China and Russia has raised concerns in India. Russia, traditionally a close partner to India, now shares a strong relationship with China, India’s primary geopolitical adversary.
  • Trade Disparity: India’s trade with Russia remains relatively small compared to the rapidly growing China-Russia trade. This economic disparity limits Moscow’s autonomy in maintaining a balanced relationship between India and China.
  • Russia’s Diminishing Autonomy: Given the economic asymmetry and Russia’s increasing reliance on China, especially for critical goods and financial support, it has less leverage to act independently in its relations with India.  

Way forward: 

  • Diversify Strategic Partnerships: India should strengthen its ties with other global powers, including the U.S., the EU, and emerging economies, to reduce over-reliance on Russia for defense and energy.
  • Expand Domestic Capabilities: India must invest in boosting its indigenous defence and energy sectors to minimize dependence on foreign partners. Strengthening self-reliance will help India maintain strategic autonomy amid shifting global alliances.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

A climate crisis agenda remains urgent

Note4Students

From UPSC perspective, the following things are important :

Mains level: Challenges due to climate change;

Why in the News?

Although voters voiced concerns about the climate crisis, it was overlooked during the Lok Sabha election campaign.

2023 Climate Targets of Indian Government

  • Renewable Energy Goals: India aims to achieve 500 GW of non-fossil fuel-based energy capacity by 2030, with a target for 50% of its total energy needs to come from renewable sources.
  • Emissions Goals: The updated Nationally Determined Contributions (NDC) set a goal to reduce emissions intensity of GDP by 45% compared to 2005 levels by 2030.
  • Carbon Sink Targets: India plans to create an additional carbon sink of 2.5–3 billion metric tons of CO2 equivalent through enhanced forest and tree cover by 2030.
  • Net Zero Commitment: Aiming for net zero emissions by 2070, India has committed to significant reductions in projected emissions, including a pledge to reduce one billion tonnes of emissions from now until 2030.
    • As of late 2023, India has already achieved a cumulative electric power capacity from non-fossil fuel sources at approximately 43.81%, ahead of its initial targets.

Why is addressing the climate crisis an urgent priority for policymakers and the global community?

  • The Paris Agreement includes a commitment for developed countries to mobilize $100 billion per year by 2020 to support climate action in developing countries. This target was extended until 2025, with new financial goals.
    • The next five years are crucial for India’s climate action to meet its ambitious 2030 targets, as the Roadmap for 2025 Climate Change Funds are about to end.
  • India’s heavy dependence on coal, with clean energy contributing only 22% of the electricity mix, underscores the need for an urgent transition.
  • Immediate attention is required to manage heat stress, improve air quality, handle waste, and enhance energy efficiency.

What specific actions or policies can be implemented?

  • Enhanced Carbon Markets: Launching the ‘India Carbon Market’ in 2026 aims to help achieve Nationally Determined Contributions (NDCs) and could become the world’s largest emissions trading system by 2030.
  • Mitigating Pollutants: Focus on reducing CO2 and short-lived superpollutants like methane, black carbon, and hydrofluorocarbons, which have significant short-term warming effects.
    • Integrating specific treaties into the Paris Agreement, similar to the Montreal Protocol, with a new treaty targeting methane reductions by 2030 would be helpful.
  • Financial Incentives: Developing financial mechanisms and nuanced carbon trading approaches to encourage faster climate action and effective pollutant management.

What challenges or barriers exist in the implementation of a comprehensive climate crisis agenda?

  • Governance and Coordination: Need for a Constitutional nodal authority to ensure coordinated climate action across various government levels and stakeholders.
  • Economic and Social Factors: Rising temperatures and associated crises like unemployment and high living costs contribute to public disengagement from climate issues.
  • Political and Voter Engagement: The 2024 Lok Sabha election’s lack of focus on climate issues highlights the challenge of integrating climate action into mainstream political agendas and addressing voter concerns.

Way forward: 

  • Create a Constitutional Nodal Authority: Form a central body with the authority to oversee, coordinate, and enforce climate policies across various government levels, ensuring effective and unified action.
  • Prioritize Climate Issues in Political Platforms: Make climate action a central theme in political campaigns and public discussions to boost awareness, engagement, and support for climate policies and initiatives.

How good are Modern Telescopes?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Telescopes

Why in the News?

Modern telescopes, both on Earth and in space, expand our understanding of the universe by gathering and focusing light from distant celestial bodies, revealing cosmic secrets.

Modern Telescopes: Everything you need to know

Primary Functions and Features

Purpose  • Telescopes serve as windows into space, revealing distant celestial bodies and helping explore the universe.
• Their primary function is to gather more light than the human eye can, making faint objects visible.
Types 1. Reflecting Telescopes:
• Use mirrors to focus light and create images.
• Most common in large observatories due to the use of parabolic mirrors, which prevent light scattering and offer clear images.
2. Refracting Telescopes:
• Use lenses to bend and focus light (Concave and Convex lenses used)
• Limited by lens size, with a maximum of about 1 meter (e.g., Yerkes Observatory). Large lenses may sag, distorting the image.
Primary purpose  • Telescopes are designed to collect more light than the human eye.
• The light-gathering ability is proportional to the size of the aperture (opening).
• Example: A small 70mm telescope collects 118 times more light than the human eye.

Features of Telescopes

Brightness and Magnitude • Celestial objects’ brightness is measured in apparent magnitude (lower numbers = brighter).
• Examples: Sun (-26.78), Venus (-4.92), Sirius (-1.46), Andromeda Galaxy (+3.44).
• Small telescopes can detect objects with magnitudes up to +11.2, which are 100 times fainter than what the human eye can see.
Resolution and Detail • The resolution of a telescope determines how much detail it can show.
• A small telescope can resolve details 1.47 arcseconds apart (40 times more detail than the human eye, which resolves details 60 arcseconds apart).

Why are Telescopes set up on Mountains?

Mountaintop benefits • High-altitude observatories are set up to reduce atmospheric distortion, which affects image quality (e.g., stars twinkling).
• Space telescopes, like Hubble, are entirely above the atmosphere and provide clear, undistorted images.
Adaptive Optics • Ground-based telescopes use adaptive optics to correct atmospheric distortions.
• Lasers create artificial stars, and the telescope adjusts its mirrors to reduce twinkling.

About the New Segmented Mirrors

Overcoming Mirror Limitations • Large mirrors (over 8.5 meters) can sag under their own weight.
Segmented mirrors solve this by using smaller sections to create larger, effective mirrors (e.g., Extremely Large Telescope (ELT) with a 39.3-meter aperture).
Notable Telescopes  Large Binocular Telescope (LBT): Two 8.4-meter mirrors, combined aperture of 11.9 meters.
Extremely Large Telescope (ELT): Under construction in Chile, it will have a 39.3-meter aperture.
Subaru Telescope (Hawaii): Captured objects with a magnitude of +27.7, 100 million times fainter than what the human eye can see.

 

PYQ:

[2015] In the context of modern scientific research, consider the following statements about ‘IceCube’, a particle detector located at South Pole, which was recently in the news:

1. It is the world’s largest neutrino detector, encompassing a cubic kilometre of ice.
