Southwest Monsoon 2026: Why a 42% Rain Deficit Worries the RBI on Growth, Inflation

Why in News

The Reserve Bank of India's June 2026 Bulletin, in its "State of the Economy" article, has cautioned that an adverse south-west monsoon could weigh on India's growth and inflation outlook. The warning comes as nationwide cumulative rainfall has fallen to 42% below the Long Period Average as on 21 June, even as heavy rain triggers landslides in Meghalaya and floods in Assam. The same bulletin disclosed that the RBI net sold $8.94 billion in April to defend a record-low rupee. This article explains the southwest monsoon's mechanism, the El Niño link, how a weak monsoon transmits into food inflation and slower growth, the RBI's forex defence and monetary-policy response, and the buffers that cushion India this year.

Why in News

The United States Trade Representative (USTR), Jamieson Greer, is set to visit New Delhi on June 23-24, 2026, to give the "final touches" to the framework of the much-awaited India-US trade deal and to push the broader Bilateral Trade Agreement (BTA). It is the first visit by a US trade chief since negotiations began in early 2025 under the Mission 500 target. The talks come amid a lingering US Section 301 investigation into India's "industrial overcapacity" and a separate forced-labour probe that could trigger fresh tariffs. This article explains the trade deal, the tariff timeline, the working of Section 301 of the US Trade Act of 1974, the BTA roadmap, the key sticking points such as farm market access, and what the deal means for India.

Strait of Hormuz Explained: LNG Tanker Disha, the US-Iran Deal and India's Energy Security

Why in News

An Indian liquefied natural gas (LNG) carrier, Disha, has become the first Indian merchant vessel in nearly two months to transit the Strait of Hormuz, following the announcement of a provisional US-Iran ceasefire deal that is expected to reopen the world's most important oil chokepoint. The transit, carrying Qatari LNG for India, has refocused attention on India's deep dependence on West Asian energy and on the vulnerability of a single maritime corridor. This article explains the geography of the Strait of Hormuz, the 2026 West Asia war that triggered its closure, why the chokepoint is critical for India's crude, LNG and LPG supplies, the international law on straits under UNCLOS, India's response through naval and diplomatic action, and the structural options to reduce this dependence.

US-Iran MoU Explained: Strait of Hormuz Reopening, the 60-Day Deal and India's Energy Security

Why in News

The United States and Iran have reached an initial agreement — a memorandum of understanding (MoU) — to end more than three months of war and reopen the strategic Strait of Hormuz, with formal signing scheduled in Geneva. The deal extends a fragile ceasefire by 60 days, lifts the US naval blockade on Iranian ports, and pushes the harder questions of Iran's nuclear programme and sanctions into a fresh round of talks. This article explains what has been agreed, the geography and global stakes of the Strait of Hormuz, the background of the 2026 Iran war and the JCPOA, and — most importantly for the aspirant — why this distant West Asian deal directly shapes India's energy security, inflation and foreign policy.
