What: The Reserve Bank of India (RBI) banned Authorised Dealers (ADs) — banks and financial institutions licensed to deal in foreign exchange — from offering Non-Deliverable Derivative (NDD) contracts in the Indian Rupee (INR) to both resident and non-resident users, effective 1 April 2026. The circular also banned the rebooking of cancelled forex contracts and related-party INR derivatives. Following the announcement, the rupee recovered sharply from Rs 95 to approximately Rs 93 per US Dollar (USD).

How: NDD contracts exist because India maintains capital controls and the INR is not fully freely convertible. Offshore investors had been using cash-settled contracts — settled in USD without physical INR delivery — in financial centres such as Singapore, London, Hong Kong, and Dubai. These offshore Non-Deliverable Forward (NDF) markets were distorting onshore price discovery and being misused for speculative ‘rebooking’ of contracts. The INR had depreciated approximately 10% in FY26 (Financial Year 2026), its worst annual fall since FY2011-12.

Why: This is a landmark forex regulatory action directly relevant to UPSC Prelims (GS-III: Economy), RBI Grade B, and IBPS PO exams. Key MCQ anchors: NDD/NDF full forms, effective date (1 April 2026), offshore trading hubs, rupee recovery (Rs 95 → Rs 93), India’s capital control context, INR’s 10% FY26 depreciation.

What: The Government of India (GoI) announced its H1 (April–September) FY27 (Financial Year 2026-27) market borrowing plan of Rs 8.20 lakh crore, representing 51% of the revised full-year gross borrowing target of Rs 16.09 lakh crore. The plan includes Rs 15,000 crore in Sovereign Green Bonds (SGrBs) — government debt securities that ring-fence proceeds exclusively for green and sustainable projects such as renewable energy, clean transport, and water management. India first issued SGrBs in January 2023 (Rs 16,000 crore). The Ways and Means Advances (WMA) limit — a short-term RBI credit facility to bridge government cash-flow gaps, repayable within 90 days at the Repo Rate — was set at Rs 2.50 lakh crore for H1 FY27.

How: Borrowing will proceed via 26 weekly auctions across maturities ranging from 3 to 50 years, with 10-year securities carrying the highest share at 29.0%. A greenshoe option of up to Rs 2,000 crore per security allows the government to retain additional subscriptions beyond the notified amount. SGrBs are aligned with the International Capital Market Association (ICMA) Green Bond Principles and India’s Nationally Determined Contributions (NDCs) under the Paris Agreement.

Why: Government borrowing mechanics, green bond frameworks, and WMA are core topics for UPSC Prelims (GS-III: Economy & Fiscal Policy), RBI Grade B, and IBPS PO. Key MCQ anchors: Rs 8.20 lakh crore, 51% of Rs 16.09 lakh crore, Rs 15,000 crore SGrBs, WMA at Rs 2.50 lakh crore, 26 auctions, greenshoe option (Rs 2,000 crore), India’s first SGrB issuance (January 2023).

What: World Health Day is observed every year on 7 April, marking the founding of the World Health Organization (WHO) on 7 April 1948, with headquarters in Geneva, Switzerland. The 2026 theme is ‘Healthy Beginnings, Hopeful Futures’, focused on maternal and newborn health. The current WHO Director-General is Dr. Tedros Adhanom Ghebreyesus of Ethiopia, in office since 2017 and re-elected in 2022.

How: The theme spotlights the global effort to reduce Maternal Mortality Ratio (MMR) — the number of maternal deaths per 100,000 live births. India has made significant progress: MMR fell from 254 (2004–06) to 97 (2018–20). The Sustainable Development Goal (SDG) 3.1 target is to reduce MMR to below 70 per 100,000 live births by 2030. India’s progress is attributed to schemes such as Janani Suraksha Yojana (JSY), Pradhan Mantri Surakshit Matritva Abhiyan (PMSMA), and improved institutional deliveries.

Why: World Health Day themes, WHO founding details, and India’s health indicators are frequently tested in UPSC Prelims (GS-II: Health), SSC, and State PSC exams. Key MCQ anchors: 7 April, WHO founded 1948, Geneva HQ, Dr. Tedros (Ethiopia), 2026 theme, India MMR trajectory (254 → 97), SDG 3.1 target (below 70 by 2030).

What: The Ministry of Defence (MoD) signed a Rs 1,950 crore contract with Bharat Electronics Limited (BEL) — a Navratna Defence Public Sector Undertaking (DPSU) established in 1954, headquartered in Bengaluru — for the procurement of Mountain Radars under the Buy (IDDM) category. IDDM stands for Indigenously Designed, Developed and Manufactured — the highest priority category under the Defence Acquisition Procedure (DAP), reserved for products developed entirely within India. The radars are designed to detect Unmanned Aerial Vehicles (UAVs), aircraft, and cruise missiles at ranges of 300–400 km, and are planned for deployment in Jammu & Kashmir and Nagaland.

How: The Mountain Radar was indigenously designed by DRDO’s (Defence Research and Development Organisation’s) LRDE — the Electronics & Radar Development Establishment, based in Bengaluru — India’s premier radar research and development laboratory. LRDE has previously developed the Ashwini (Active Electronically Scanned Array Low Level Tracking Radar), Rohini (Advanced Fixed Array Radar for the Indian Air Force), and various Battlefield Surveillance Radars (BFSR-SR). BEL is responsible for series production.

Why: This contract reflects India’s push for atmanirbharta (self-reliance) in defence electronics and border surveillance technology, critical for both the northern and northeastern frontiers. It is testable in UPSC Prelims (GS-III: Defence & Internal Security), CDS, and CAPF exams. Key MCQ anchors: Rs 1,950 crore, Buy (IDDM) category, LRDE (Bengaluru), BEL (Navratna, est. 1954), 300–400 km detection range, deployment in J&K and Nagaland.

What: The Government of India kept Small Savings Scheme (SSS) interest rates unchanged for the 8th consecutive quarter for Q1 FY27 (1 April to 30 June 2026). Key rates: Sukanya Samriddhi Yojana (SSY) at 8.2%, Public Provident Fund (PPF) at 7.1%, Senior Citizens Savings Scheme (SCSS) at 8.2%, Kisan Vikas Patra (KVP) at 7.5% (matures in 115 months), 3-year Time Deposit (TD) at 7.1%, National Savings Certificate (NSC) at 7.7%, Monthly Income Scheme (MIS) at 7.4%, and Post Office Savings Account at 4%.

How: Small Savings Scheme rates are notified by the Ministry of Finance on a quarterly basis and are structurally linked to Government Securities (G-Sec) yields of comparable maturities, with a mandated spread. Collections from these schemes flow into the National Small Savings Fund (NSSF), which is used to partly finance the fiscal deficit. Rate stability over 8 quarters reflects the government’s intent to maintain household savings incentives while managing the overall cost of borrowing.

Why: Small Savings rates, their linkage to G-Sec yields, and the NSSF are standard topics in Banking exams (IBPS PO/Clerk, RBI Grade B, SBI PO) and UPSC Prelims (GS-III: Economy). Key MCQ anchors: 8th consecutive unchanged quarter, Q1 FY27 (Apr–Jun 2026), SSY = 8.2%, PPF = 7.1%, SCSS = 8.2%, KVP = 7.5% (115 months), NSC = 7.7%, MIS = 7.4%, NSSF, G-Sec yield linkage.

What: Continuous At-Sea Deterrence (CASD) is a nuclear doctrine that requires at least one Submarine Submersible Ballistic Nuclear (SSBN) vessel to be on active patrol at all times, ensuring an uninterrupted second-strike nuclear capability. Achieving CASD requires a minimum fleet of 3–4 SSBNs, since vessels must rotate between active patrol, maintenance, and crew training cycles. With the commissioning of INS Aridhaman in April 2026 — following INS Arihant (2016) and INS Arighaat (August 2024) — India has crossed this threshold for the first time. (See also: 5 Apr 2026 — INS Aridhaman commissioning.)

How: SSBNs are uniquely suited to second-strike capability because they are mobile, submerged, and extremely difficult to locate and destroy in a first nuclear strike. Unlike land-based missiles (which can be targeted by satellite imagery) or airborne delivery (which requires aircraft survivability), a patrolling SSBN provides assured retaliation. CASD means an adversary can never be confident of eliminating India’s nuclear response in a pre-emptive strike — this is the strategic logic of nuclear deterrence stability.

Why: CASD and the nuclear triad concept are recurring themes in UPSC Mains (GS-III: Internal Security & Defence), Essay Paper, and CDS/NDA. Key MCQ anchors: CASD full form, minimum 3–4 SSBNs required, India’s three SSBNs (Arihant 2016, Arighaat Aug 2024, Aridhaman Apr 2026), second-strike capability, Project Varsha base (Visakhapatnam), nuclear triad completion.
