# Economic geography of the world: trade, transport & regions

World economic geography for UPSC: global trade routes, chokepoints, transport networks, industrial regions and resource flows tested in GS-1 and Prelims.

## The Architecture of World Trade

Global commerce moves overwhelmingly by sea: roughly 80% of merchandise trade by volume travels on ships, channelled through a small number of maritime arteries whose security defines geopolitics. The candidate must memorise the principal chokepoints and the canals that compress them.

The **Strait of Hormuz**, between Iran and Oman, carries about one-fifth of global petroleum consumption (some 20 million barrels/day) from the Persian Gulf. The **Strait of Malacca**, between the Malay Peninsula and Sumatra, is the shortest sea route between the Indian and Pacific Oceans and carries roughly a quarter of traded goods and most of China's oil imports — the source of Beijing's so-called 'Malacca Dilemma'. The **Bab-el-Mandeb**, linking the Red Sea to the Gulf of Aden, became headline news after the Houthi attacks of 2023–24 forced shipping around the Cape of Good Hope.

Two artificial cuts transformed world trade. The **Suez Canal**, opened 17 November 1869 and nationalised by Nasser on 26 July 1956 (triggering the Suez Crisis), shortens the Europe–Asia route by avoiding the Cape; its 2021 blockage by the *Ever Given* halted some $9.6 billion of daily trade. The **Panama Canal**, opened 15 August 1914 and transferred fully to Panama on 31 December 1999 under the Torrijos–Carter Treaties (1977), links the Atlantic and Pacific and has faced drought-driven draft restrictions on Gatún Lake since 2023.

## Routes of Empire and Energy

The **Cape of Good Hope** route, pioneered by Vasco da Gama (reaching Calicut, 1498), regained relevance whenever the Suez–Red Sea corridor is disrupted. The **North Sea Route** along the Arctic Russian coast is opening as sea ice retreats, promising a shorter Asia–Europe passage. The **Great Circle routes** of the North Atlantic and North Pacific carry the densest container and bulk traffic between the North American, European and East Asian economic cores.

Commodity flows follow predictable axes: crude oil from the Gulf, West Africa and Russia to Asia, Europe and North America; iron ore from Australia (Pilbara) and Brazil (Carajás) to East Asian steel mills; grain from the US Midwest, Argentine Pampas, Ukraine and the Canadian Prairies to deficit regions. Container trade concentrates manufactured goods exports from East Asia — the 'workshop of the world' — toward Western consumer markets, the structural basis of persistent trade imbalances.

India's stakes are direct. The **Chabahar port** (Iran) and the **International North–South Transport Corridor (INSTC)**, agreed 2000 and operational in phases, give India a Russia and Central Asia link bypassing Pakistan. The **Suez–Red Sea–Indian Ocean** axis carries the bulk of India's EU trade, and disruptions at Bab-el-Mandeb raise Indian freight and insurance costs immediately — a live illustration of how chokepoint geography becomes economic policy.
