Pre & Mains Notes

1. Who pays for Trump tariffs? Almost exclusively Americans What happened • A study finds that U.S. tariffs under Donald Trump operated as a consumption tax borne mainly by American consumers and importers. Issue raised • Who ultimately bears the economic burden of tariffs and their effectiveness as a trade policy tool. Current context • U.S. customs revenue rose by about $200 billion by 2025. • Import prices increased; foreign exporters largely did not absorb tariffs. • Import volumes declined, especially from China. • High tariffs on Brazil and India led to volume reduction rather than price cuts. Why it matters • Questions the assumption that tariffs hurt foreign producers. • Shows inflationary impact on domestic consumers. • Relevant for future trade and protectionism policy choices. --- 2. How reusability can lead to sustainable, cost-effective access to space? What happened • Reusable rocket technologies are lowering launch costs and increasing mission frequency in the commercial space sector. Issue raised • Role of technological innovation in enabling sustainable and cost-effective access to space. Current context • Reusability reduces costs compared to expendable rockets. • Rocket staging addresses fuel-weight constraints. • Engine wear, thermal stress, and refurbishment limit reuse cycles. • India is exploring recovery options including RLVs and stage recovery. Why it matters • Improves affordability and frequency of space missions. • Strengthens strategic and commercial space capabilities. • Impacts India’s competitiveness in the global space market. --- 3. Trump slams U.K.’s move to hand over Chagos Islands What happened • Donald Trump criticised the U.K.’s decision to transfer sovereignty of the Chagos Islands to Mauritius. Issue raised • Balancing decolonisation claims with strategic military and security interests. Current context • U.K. and Mauritius agreed to transfer sovereignty after prolonged dispute. • Diego Garcia to remain under U.K.–U.S. control on a 99-year lease. • UN has supported Mauritius’ sovereignty claim. • Chagossians were displaced in the 1960s; legal challenges persist. Why it matters • Affects U.S. military positioning in the Indian Ocean. • Highlights tension between international law and strategic interests. • Relevant for geopolitics and decolonisation norms.

Pre & Mains Notes

1. US annexation of Greenland – implications What happened US President Donald Trump reiterated interest in acquiring Greenland, triggering diplomatic and strategic debate. Issue raised How US annexation of Greenland would affect NATO unity, Russia’s strategy, and Arctic geopolitics. Current context - Greenland is an autonomous territory under Denmark (a NATO member). - Any US move would involve Denmark, NATO consultations, and international law. - Arctic region is gaining importance due to melting ice, new sea routes, and resources. Why it matters NATO: Internal friction if a member’s territory is pressured by another member. Russia: Increased militarisation of the Arctic; Russia already expanding bases. Global order: Sets precedent of territorial acquisition rhetoric in a rules-based system. 2. Blockbuster cancer drug Nivolumab may get cheaper What happened Delhi High Court ruling opens the door for biosimilar versions of Nivolumab after patent-related litigation. Issue raised Access vs innovation debate in life-saving cancer drugs. Current context - Nivolumab is an immunotherapy drug used against multiple cancers. - Current treatment cost is extremely high and largely unaffordable in India. - Indian pharma companies may soon produce cheaper biosimilars. Why it matters Public health: Wider access to advanced cancer treatment. Pharma policy: Balancing patent protection with compulsory licensing / biosimilars. Healthcare costs: Significant reduction in out-of-pocket expenditure. 3. Digital currency link on BRICS agenda What happened RBI recommended including linkage of central bank digital currencies (CBDCs) on the BRICS agenda. Issue raised Reducing dependence on the US dollar in cross-border payments. Current context - India will host the BRICS summit in 2026. - All BRICS members are running CBDC pilot projects. - Proposal focuses on interoperability, not a single BRICS currency. Why it matters Geopolitics: Dollar dominance vs multipolar financial order. Payments: Faster, cheaper cross-border settlements. India’s role: Positions digital rupee as a global settlement instrument.

Pre & Mains Notes

1) Election, lottery, election: How Mumbai will get new mayor What happened Mumbai will not get a mayor through a direct vote. The post will be decided through a lottery-based reservation system, followed by an internal election among corporators. Issue raised The mayor’s post is reserved by rotation, not political choice, delaying clarity and limiting parties’ ability to project candidates. Current context * Reservation follows the 74th Constitutional Amendment * Categories include SC, ST, OBC, and women * Reservation is decided by a draw of lots conducted by the Urban Development Department * Only after reservation is declared does voting take place in the BMC House Why it matters Highlights how urban governance prioritises constitutional equity over electoral politics, but also weakens the mayor’s political authority in India’s richest civic body. 2) Can the Chinese government arrest its ageing problem? What happened China is rolling out multiple policy interventions to reverse population ageing after the failure of the one-child policy rollback. Issue raised Low fertility rates, shrinking workforce, and rising elderly dependency threaten China’s long-term economic growth. Current context * One-child policy abolished in 2016 * Retirement age gradually increased * Incentives for childbirth, tax breaks, housing support * Expanded childcare services and family-friendly policies * Despite measures, birth rates continue to fall Why it matters China’s demographic slowdown could reshape global manufacturing, supply chains, and economic power, affecting countries like India that compete for labour-intensive growth. 3) Soft matter: the unusual yet persistent physics inside your bathroom cabinet What happened Scientists explain why everyday products like toothpaste and shampoo behave as both solids and liquids, a property of soft matter physics. Issue raised Traditional physics models fail to explain materials that flow under pressure but hold shape at rest. Current context * Toothpaste, shampoo, gels are examples of soft matter * Behaviour depends on force, time, and internal structure * Linked to concepts like viscosity, molecular rearrangement, and stress response * Pitch-drop experiment shows extreme slow-flow behaviour Why it matters Soft matter research improves industrial design, consumer products, biomedical materials, and material science, bridging physics with real-life applications.

Pre & Mains Notes

1. SC & ‘Romeo–Juliet’ Exception under POCSO What happened Supreme Court asked the Union government to consider introducing a “Romeo–Juliet” exception under the POCSO Act to avoid criminalising consensual adolescent relationships. Issue raised Blanket criminalisation under POCSO treats all sexual activity involving minors as abuse, ignoring consent and proximity in age. Current context • POCSO criminalises all sexual acts below 18, regardless of consent • Courts increasingly see misuse in cases involving adolescents in consensual relationships • PILs and High Court rulings highlight disproportionate incarceration of young men Why it matters • Balances child protection with adolescent autonomy • Prevents misuse of law by families to control relationships • Raises constitutional questions on dignity, autonomy, and proportionality 2. India must widen export pool to offset US tariffs What happened Economic analysis suggests India needs to diversify and deepen its export base to counter potential trade disruptions from US tariffs. Issue raised Overdependence on limited markets and products makes Indian exports vulnerable to protectionist shocks. Current context • US tariffs impact Indian sectors like pharmaceuticals, chemicals, textiles • Export growth driven more by volume than diversification • Global trade fragmentation is increasing Why it matters • Export resilience is key to growth and forex stability • Pushes India towards new markets, value-added goods • Aligns with “China+1” and supply chain diversification trends 3. India’s late entry into US-led groupings (Pax Silica) What happened India’s inclusion in Pax Silica, a US-led critical minerals and technology grouping, came after initial exclusions, raising strategic concerns. Issue raised India risks being seen as an afterthought in emerging tech and supply-chain alliances. Current context • Pax Silica focuses on critical minerals, semiconductors, AI supply chains • US is structuring minilateral groups to reduce China dependence • India has capabilities but lacks early agenda-setting presence Why it matters • Highlights need for proactive economic diplomacy • Strategic relevance now depends on tech, data, and minerals • India must enter alliances with clear value propositions, not just strategic goodwill
