  • Finance ministry June review: High-frequency indicators such as e-way bill generation, PMI readings, electricity consumption, and automobile sales continued to show strength in domestic demand. Some indicators were moderating, which pointed to “some easing in momentum.”

Monsoon and agriculture

  • Rainfall: India had a very weak June monsoon. One reading showed June rainfall 39.8% below the long-term average, at 99.5 mm against a normal 165.3 mm, making it the fifth-driest June since 1901. Another end-June reading showed rainfall 42% below normal, at 92.2 mm against 157.7 mm, and put India on track for its third-driest June in a century. The two readings used different cut-offs and reference baselines. The shortfall was linked to a strengthening El Niño.
  • Kharif sowing: Kharif sowing lagged because of the delayed monsoon. Total acreage was down 23% year-on-year to 18.27 million hectares. Paddy acreage fell 25%, and oilseed acreage fell more than 53%.

Sector and trade policy

  • Two-wheelers under CAFE: The Centre plans to introduce corporate average fuel efficiency, or CAFE, rules for motorcycles and scooters from April 2028. Two-wheelers account for nearly one-third of India’s annual petrol consumption of 42.6 million tonnes. India imports nearly 90% of its crude oil needs.
  • Semiconductors and petrochemicals: The finance ministry cleared a ₹1.25 trillion allocation for India Semiconductor Mission 2.0. ISM 1.0 had an outlay of ₹76,000 crore. Duty-free petrochemical imports were extended till 15 July. The government raised the windfall tax on petrol exports and cut the levy on diesel and ATF.
  • Welfare spending: An Azim Premji University report said India spends about 4.0% of GDP on social protection, excluding health. In 2023-24, states spent ₹15,100 per capita on social spending, compared with the Centre’s ₹2,150. Cash-transfer allocations rose about 20-fold between 2015-16 and 2024-25, reaching 11% of total social-sector spending.

International headlines

  • US-Iran talks: A Qatari official said US envoys Jared Kushner and Steve Witkoff, who arrived in Doha, would hold technical talks rather than a high-level meeting. This raised doubt about progress toward fully reopening the Strait of Hormuz. The 14-point interim pact gives 60 days to negotiate a permanent truce in the conflict, which began with US and Israeli strikes on Iran on 28 February. Iran also resumed scheduled flights to Dubai.
  • Gold and crude: Gold held near $4,020 an ounce, close to its lowest level since November 2025. It fell 11% in June and 14% for the quarter, its steepest quarterly fall since Q2 2013. Crude oil traded near $70.7 a barrel and ended Q2 with an approximately 30% drop, its steepest quarterly fall since 2020. Improved Strait of Hormuz shipping and US sanctions waivers on Iranian oil raised expectations of higher supply.
  • Germany inflation: Germany’s annual inflation eased to 2.4% in June from 2.7% in May. This was below a Reuters forecast of 2.5%. Core inflation stayed unchanged at 2.5%, based on preliminary data.
  • Corporates: Siemens Energy rose about 5% after an optimistic order-inflow outlook on its Q3 pre-close call. Meituan said it had open-sourced its next-generation LongCat large language model. The company described it as the world’s first trillion-parameter AI system trained and operated entirely on a 50,000-chip cluster powered by Chinese-made processors.
  • US markets and deals: The S&P 500’s Q1 net profit margin rose to a record 14.8%, based on FactSet data, with earnings growth of 28.8%. Comcast’s planned NBCUniversal spinoff was flagged as the next major Hollywood deal target.

Feature: How the AI boom and geopolitics are rewiring Asia’s oceans

Scale of the build-out

Subsea fibre-optic cables carry more than 95% of international internet traffic. The next investment cycle is large. Paul Brodsky, senior research manager at TeleGeography, said the value of new submarine cables planned to enter service from 2026 to 2029 is more than $16 billion. He described subsea investment as being at its highest level since 2000-2001, with a clear rise in activity across Asian routes.

TeleGeography projects that international bandwidth used by major cloud, AI, and social-media providers will rise ninefold between 2025 and 2035. These providers accounted for about 75% of all used international capacity in 2025. Autonomous AI agents are expected to increase bandwidth demand further.

AI infrastructure and data-centre routes

Hyperscalers are treating subsea cables as strategic infrastructure that links data centres. The aim is not only connectivity, but also low latency and redundancy. Examples include Google Cloud’s TalayLink between Australia and Thailand and Meta’s Candle across several Asian markets.

Asia’s AI infrastructure is taking shape as a corridor of connected hubs: Singapore-Batam, Thailand, Indonesia, the Philippines, India, and Japan. Julian Rawle, associate partner for subsea at Cambridge Management Consulting, said there is no freely available data yet on AI’s true bandwidth impact. His firm is therefore using a disciplined assumption of a 10% uplift above underlying demand forecasts until there is real-world evidence. TeleGeography figures cited by the IEEE ComSoc Technology Blog show that intra-Asia routes attracted about $1.2 billion of recent subsea investment.

Ownership and manufacturing concentration

Amazon, Google, Meta, and Microsoft now own or lease around half of all undersea bandwidth worldwide. Manufacturing and installation are also highly concentrated. Around 98% of the world’s undersea cables are manufactured and installed by four firms: SubCom in the United States, Alcatel Submarine Networks in France, NEC in Japan, and HMN Technologies in China.

CSIS

Goldman Sachs estimated that these hyperscalers could invest nearly $765 billion in AI-related capital expenditure during the 2026 fiscal year.

Chokepoints and permitting friction

Singapore shows why subsea routes matter. More than 99% of Singapore’s international telecommunications traffic is carried by subsea cables. China has introduced stricter permitting and has started requesting permits for cable-laying in claimed territorial waters beyond 12 nautical miles.

Higher Chinese activity in the South China Sea has contributed to delays on systems such as SJC-2 and has created permitting challenges. This is pushing developers to consider alternative designs, including routes running south through the Java Sea or routes that skirt the edge of China’s self-declared nine-dash line near the Philippines and Borneo.

Security and cable cuts

Since 2023, there have been at least 11 cases of subsea cable breakdowns around Taiwan. Some were later ruled accidents or linked to ageing equipment. Taiwan has described some incidents as grey-zone or hybrid-warfare tactics, while China has denied involvement.

In June, a Taiwanese court sentenced the Chinese captain of the vessel Hong Tai 58 to three years in jail for intentionally damaging cables off Taiwan. CSIS has written that China’s unveiling of a ship designed to cut undersea cables signals that it sees such disruption as a coercive tool in the Taiwan Strait, the South China Sea, and beyond.

India connection

Tata Communications will invest $152 million to strengthen subsea cable infrastructure between India and Singapore. The investment will add around 98 terabits per second across two projects.

  • MIST system: $63 million for a Mumbai-Singapore system with about 20 tbps, targeted for ready-for-service in Q4 FY27.
  • Project CS: $89 million as a consortium member for a Chennai-Singapore system with about 78 tbps, slated for Q3 FY31.

Tata Communications will also invest in new subsea cable infrastructure between India and Singapore to serve rising demand from cloud, data centres, and AI services.
