UPSC CSE Current Affairs — 28 September 2026

Economists expect the RBI's MPC to raise the repo rate by 25 basis points at its October 5–7 meeting, driven by rising crude oil prices (Brent at $102/barrel), broadening CPI inflation (4.82% in August), and global central bank tightening. The RBI held rates at 5.25% in August. Total hikes this cycle are projected at 50–75 bps across October and December meetings, though some analysts warn tightening risks damaging growth and rural incomes.

This article tests a core transmission mechanism: how external supply shocks feed into domestic monetary policy decisions.

The RBI operates an inflation-targeting framework under which CPI inflation must be kept at 4% (±2%). When inflation threatens to breach the upper tolerance band of 6%, the MPC is mandated to explain and, typically, act. The article shows inflation broadening — from 22 commodities driving 90% of CPI weight in January 2026 to 51 commodities by August 2026 — signalling a supply-side shock becoming demand-generalised, the threshold that typically triggers rate action.

The LAF corridor mechanism: the repo rate is the rate at which banks borrow overnight from RBI. Raising it raises the cost of funds for banks, which pass this on as higher lending rates, cooling credit demand, consumption, and ultimately inflation. However, monetary transmission has lags — 3–6 quarters typically — which is why RBI says it may act before Q3 data confirms broadening.

The article also illustrates the monetary policy dilemma: oil shocks are simultaneously inflationary (raise input costs) and demand-destructive (squeeze real incomes). Raising rates to fight inflation when growth is already moderating risks over-tightening. Q1 FY27 GDP of 7.8% provides comfort, but rural stress from rainfall deficits complicates the picture.

For NABARD aspirants: higher repo rates directly raise NABARD's refinancing costs, tightening agricultural credit availability — a classic second-order effect of monetary tightening on rural finance.

Economists at DBS Bank and HSBC expect RBI's MPC to raise the repo rate by 25 basis points at its October meeting, with a second 25 bp hike projected for December, taking the repo rate to 5.75 per cent. Excess liquidity, which peaked near ₹10–11 lakh crore, has narrowed below ₹5 lakh crore after RBI used VRRR auctions, OMO sales, and FX swaps. CRR hikes and MSS issuance remain under active consideration to tighten conditions further.

This article captures a critical phase in RBI's monetary tightening cycle, where two distinct levers — the policy rate and liquidity management — are being deployed simultaneously. Understanding why both matter requires grasping the LAF corridor mechanics.

The repo rate is the rate at which RBI lends overnight to banks. When excess liquidity floods the banking system, the effective overnight rate (Weighted Average Call Rate, or WACR) drifts toward the reverse repo rate — the floor of the LAF corridor — rather than staying anchored to the repo rate. This weakens monetary policy transmission: even if RBI raises the repo rate, banks that are already flush with cheap funds may not fully transmit the rate signal to borrowers.

To fix this, RBI employs liquidity absorption tools: VRRR (Variable Rate Reverse Repo) auctions absorb surplus at a market-determined rate; OMO sales (selling government securities) permanently drain liquidity; FX spot/swap sales reduce rupee liquidity by selling dollars. The article notes that these operations brought surplus liquidity from ₹10–11 lakh crore down to below ₹5 lakh crore, pulling the WACR closer to the repo rate — a sign of improved transmission.

For the October MPC meeting, the concern is dual: inflation remains elevated, and excess liquidity itself has a modest positive relationship with core inflation (more money chasing goods). CRR hikes and MSS (Market Stabilisation Scheme) bonds are additional tools — CRR locks bank reserves with RBI, while MSS bonds sterilise liquidity more permanently. Aspirants must know the distinction between all these tools and when each is deployed.

The Periyar Science and Technology Centre in Chennai is upgrading its galleries to display models of Chandrayaan missions, Mangalyaan, a space crew module, and PSLV rockets in interactive formats. The exhibits aim to make India's major space achievements accessible to the public. The upgrade is a public science outreach initiative and provides a useful occasion to revisit the key technical and historical details of ISRO's flagship missions that the UPSC examiner regularly tests.

This news serves as a timely hook to revisit the architecture of India's space programme — the missions, their payloads, launch vehicles, and firsts.

Chandrayaan-1 (2008) was India's first lunar mission, launched by PSLV-C11. It carried 11 payloads (5 Indian, 3 European, 2 American, 1 Bulgarian) and its Moon Impact Probe confirmed the presence of water molecules on the Moon — a landmark discovery. Chandrayaan-2 (2019), launched by GSLV Mk-III, consisted of an orbiter, lander (Vikram), and rover (Pragyan); the lander hard-crashed on the lunar surface. Chandrayaan-3 (2023), also launched by LVM3 (formerly GSLV Mk-III), successfully soft-landed near the lunar south pole on 23 August 2023 — making India the first country to land near the south pole and the fourth nation overall to achieve a soft lunar landing.

Mangalyaan (Mars Orbiter Mission, MOM), launched in 2013 by PSLV-C25, made India the first Asian nation and the first country to succeed in its maiden Mars mission. It was developed in a record 15 months at a cost of approximately ₹450 crore — cheaper than the Hollywood film 'Gravity.'

The crew module references India's Gaganyaan programme — ISRO's human spaceflight mission. The Crew Module Atmospheric Re-entry Experiment (CARE) was tested in 2014, and a full crewed mission is targeted for 2026. Understanding the role of PSLV, GSLV, and LVM3 as distinct launch vehicles — their payload capacities and orbit types — is essential static knowledge behind any of these missions.

External Affairs Minister S. Jaishankar met Canadian Foreign Minister Anita Anand and described the discussions as productive, with both sides agreeing to take bilateral ties to a higher level. The meeting signals a diplomatic thaw after India-Canada relations collapsed in 2023 following Canadian Prime Minister Justin Trudeau's allegations linking Indian agents to the killing of Khalistani separatist Hardeep Singh Nijjar on Canadian soil.

India-Canada relations deteriorated sharply in September 2023 when PM Trudeau publicly alleged that Indian government agents were involved in the killing of Hardeep Singh Nijjar, a Canadian citizen and designated terrorist under India's Unlawful Activities Prevention Act (UAPA). India categorically rejected the allegations and expelled a senior Canadian diplomat. Canada reciprocated, and bilateral engagement effectively froze — with both countries recalling ambassadors and India suspending visa services for Canadian citizens.

The background matters for UPSC: India-Canada bilateral ties cover trade (Canada is a top source of foreign students to India), energy (uranium supply for India's nuclear programme), and diaspora linkages (approximately 1.8 million Indo-Canadians). The Comprehensive Economic Partnership Agreement (CEPA) negotiations, which had resumed in 2022 after a decade-long gap, were paused amid the diplomatic fallout.

The change in Canadian political leadership — Justin Trudeau's resignation and Mark Carney's rise as Liberal leader and PM — opened a diplomatic window. Anita Anand, appointed as Foreign Minister under Carney's government, represents a fresh interlocutor for India. Jaishankar's description of the talks as 'productive' and the shared language of taking ties 'to a higher level' suggests both sides are willing to compartmentalise the Nijjar dispute and re-engage on trade, education, and strategic interests. For UPSC aspirants, this event tests knowledge of the diplomatic rupture's causes, the bilateral framework, and how India manages relations with countries that have significant Khalistani diaspora populations.

At a recent summit, Presidents Trump and Xi agreed to extend the US-China trade truce, pausing escalating tariff measures between the world's two largest economies. China is seen as gaining diplomatic leverage from the talks. However, the summit left Taiwan tensions unaddressed, with no substantive resolution on the longstanding flashpoint. The meeting signals a tactical pause rather than structural resolution in US-China relations, with trade and geopolitical fault lines both still active.

The Trump-Xi summit reflects the broader architecture of US-China strategic competition, which oscillates between managed engagement and confrontation. The trade truce — a pause on escalatory tariffs — follows the pattern established since the 2018-19 trade war, where both sides periodically de-escalate to avoid economic damage while maintaining structural rivalry.

For UPSC aspirants, several static frameworks are relevant here. First, the 'One China Policy' remains the formal diplomatic position accepted by most countries, including the US, which recognises Beijing but maintains unofficial relations with Taiwan through the Taiwan Relations Act (1979). Any summit outcome on Taiwan therefore operates within this constrained space — neither side can formally move without triggering a diplomatic rupture.

Second, the concept of 'strategic ambiguity' — the US deliberately not specifying whether it would militarily defend Taiwan — is a central principle in Indo-Pacific security discourse. China's diplomatic leverage stems partly from US inconsistency on this question.

Third, US-China trade architecture involves the WTO dispute settlement mechanism, bilateral Phase One and Phase Two trade deal frameworks (2020), and technology export controls (CHIPS Act, 2022). The truce operates within this layered system.

For India, US-China de-escalation has dual implications: reduced pressure on global supply chains but also a more confident China in its neighbourhood diplomacy, including along the LAC.

External Affairs Minister S Jaishankar, speaking at the UN General Assembly on September 27, indicated that India and Canada are preparing to elevate bilateral ties to a 'higher level.' The statement marks a notable diplomatic shift after a prolonged freeze triggered by Canada's 2023 allegations linking Indian agents to the killing of Khalistani separatist Hardeep Singh Nijjar, which led to mutual expulsion of diplomats and severe strain in relations.

India-Canada relations deteriorated sharply after Canadian Prime Minister Justin Trudeau accused Indian government agents of involvement in the June 2023 killing of Hardeep Singh Nijjar, a Canadian Sikh classified by India as a terrorist. India denied the allegations and termed them 'absurd.' Both countries expelled senior diplomats, Canada suspended free trade agreement (CETA) negotiations, and bilateral engagement hit its lowest point in decades.

The relationship matters strategically for several reasons. Canada hosts one of the largest Indian diaspora populations globally — over 1.8 million people of Indian origin — and is a top destination for Indian students. Bilateral trade stood at roughly CAD 12 billion (approximately USD 9 billion) annually before the crisis. India had been negotiating the Comprehensive Economic Partnership Agreement (CEPA) with Canada, which stalled amid tensions.

Jaishankar's statement at UNGA 2025 signals a possible thaw, likely influenced by the change in Canadian political leadership: Mark Carney replaced Trudeau as Prime Minister in March 2025, and his government has adopted a less confrontational posture toward India. For exam purposes, aspirants must know the key friction points — Khalistan issue, Nijjar killing, diplomat expulsions — and the institutional frameworks that define the relationship, including CEPA negotiations, the Five Eyes intelligence alliance that Canada belongs to (India does not), and India's consistent position on non-interference in internal affairs.

Following a Washington meeting described as successful, US President Donald Trump confirmed Chinese President Xi Jinping's departure and announced a follow-up bilateral meeting in China in November 2025. Both leaders agreed to support each other's hosting of major multilateral summits in 2026: the US will host APEC and China will host the G20. The development signals a managed, if cautious, stabilisation of US-China relations after a prolonged period of tariff-driven tensions.

This event sits at the intersection of bilateral diplomacy and multilateral forum hosting — two areas the examiner tests routinely. The APEC (Asia-Pacific Economic Cooperation) forum is a 21-member regional economic grouping founded in 1989 in Canberra. The G20, established in 1999 as a finance ministers' forum and elevated to a leaders' summit in 2008, includes both the US and China as founding members, along with India.

The significance here is the reciprocal hosting commitment: the US will host APEC 2026 and China will host the G20 in 2026. This mutual endorsement is diplomatically notable because it signals that despite ongoing trade friction — including historic tariff rounds that escalated through 2024-25 — both powers see value in cooperative multilateral engagement.

For exam purposes, this news event activates several static knowledge clusters: the founding year and membership of APEC and G20, India's role in both forums (India hosted G20 in 2023 in New Delhi), the rotating presidency mechanism of the G20, and the structure of US-China bilateral relations. The examiner often uses a current bilateral or multilateral event as a hook to test whether aspirants know the founding dates, headquarters, membership count, and mandate of the institutions involved.

Bhubaneswar hosted the 1st Chandaka Green Marathon on the occasion of the 72nd Wildlife Week, using the run to spotlight the Chandaka-Dampara Wildlife Sanctuary adjoining the city. Wildlife Week is observed annually during the first week of October. The event drew attention to urban wildlife conservation and the pressure on forest patches near expanding cities. Chandaka-Dampara is Odisha's only elephant reserve located inside a state capital.

Wildlife Week (October 2–8) was instituted in 1952 by India's government to build public awareness about wildlife conservation — making the 2024 edition the 72nd. The Chandaka-Dampara Wildlife Sanctuary in Bhubaneswar is a rare example of a protected area embedded within a rapidly urbanising landscape. It is home to elephants, leopards, and spotted deer and serves as a critical green corridor, though encroachment and human-elephant conflict remain persistent threats.

For exam purposes, this event unlocks two testable static layers. First, the governance layer: wildlife sanctuaries are declared under the Wildlife Protection Act, 1972 (WPA), and the nodal authority is the Ministry of Environment, Forest and Climate Change (MoEFCC). The WPA distinguishes between National Parks (higher protection, no human activity) and Wildlife Sanctuaries (limited human activity permitted). Second, the ecological layer: urban wildlife reserves face a unique set of pressures — habitat fragmentation, corridor disruption, and light/noise pollution — that differ from pressures on remote protected areas. The elephant population in Odisha falls under Project Elephant (launched 1992), and Chandaka-Dampara is designated an Elephant Reserve. India currently has 33 Elephant Reserves. Understanding the hierarchy — Elephant Reserve vs Wildlife Sanctuary vs National Park — is exactly the kind of classification the UPSC examiner tests.

External Affairs Minister S. Jaishankar met Canadian Foreign Minister to discuss elevating India-Canada bilateral relations. Jaishankar stated both countries are preparing to take their relationship to a higher level. The meeting signals a diplomatic thaw after a prolonged freeze triggered by Canada's 2023 allegations linking Indian agents to the killing of Khalistani separatist Hardeep Singh Nijjar, which had led to expulsion of diplomats and suspension of trade talks.

India-Canada relations have a complex history shaped by diaspora ties, trade interests, and persistent friction over Khalistan-linked activism on Canadian soil. The relationship formally deepened through the India-Canada Joint Declaration (2015) and ongoing Comprehensive Economic Partnership Agreement (CEPA) negotiations, which were suspended in 2023 amid the Nijjar crisis.

The bilateral framework covers several pillars: trade and investment (Canada is among India's top 15 trading partners), education (over 400,000 Indian students study in Canada), clean energy cooperation, and people-to-people ties through the large Indian diaspora. The Five Eyes intelligence alliance, of which Canada is a member, adds a strategic layer to how Ottawa positions itself relative to India's concerns about foreign interference.

For UPSC aspirants, the significance lies in India's consistent foreign policy position: it demands third countries not provide space to elements threatening India's sovereignty and territorial integrity — a principle articulated publicly by Jaishankar himself. The resumption of high-level talks after a period of downgraded engagement illustrates how India calibrates diplomatic pressure before re-engagement, a pattern visible in its handling of relations with Turkey, Maldives, and Nepal as well.

The CEPA negotiations, if revived, would be India's first FTA with a G7 nation, making the economic stakes significant alongside the political ones.

Bangladesh has suspended hilsa fish imports from India and cancelled 103 No Objection Certificates issued to importers. The trigger was widespread fraud: Indian hilsa bought at roughly Tk500 per kilogram was being relabelled and sold in local markets as premium Padma hilsa for Tk2,000–3,000 per kilogram. The Bangladesh government acted to protect consumers and the Padma hilsa's distinct geographical identity, a fish central to both Bengali culture and the bilateral fisheries trade.

Hilsa (Tenualosa ilisha) is the national fish of Bangladesh and holds immense cultural and economic significance in the Bengal delta region shared by India and Bangladesh. The Padma hilsa — caught in the Padma River — is considered the finest variety and commands premium prices due to its fat content and flavour, earned through its long migratory route from the Bay of Bengal.

India is a significant hilsa producer, particularly from the Hooghly and coastal West Bengal fisheries. Bangladesh had periodically permitted imports from India to manage domestic supply shortages, especially during festive seasons like Durga Puja and Eid. These imports required NOCs (No Objection Certificates) from Bangladesh's Department of Fisheries.

The fraud uncovered here is a classic geographical indication (GI) violation: Indian hilsa, significantly cheaper, was being passed off as the premium Padma variety — a deception that harms consumers, undercuts Bangladeshi fishers, and dilutes the brand equity of Padma hilsa. Bangladesh received GI recognition for Padma hilsa, making such mislabelling a legal violation.

For the India-Bangladesh bilateral relationship, hilsa has been a diplomatic tool — India occasionally exports hilsa to Bangladesh as a gesture of goodwill (often called 'hilsa diplomacy'). The suspension of 103 NOCs signals a regulatory tightening rather than a diplomatic rupture, but it does affect Indian fish exporters, particularly those in West Bengal.

From an exam perspective, this intersects GI tags, bilateral trade disputes, fisheries agreements, and food security governance — all tested domains.
