Domestic financial developments and international geopolitical tensions shaped the morning of October 21, 2026. State Bank of India (SBI) launched an investigation into a suspected data breach after customer records appeared on the dark web, while the Indian rupee extended its recovery to 94.48 against the US dollar. Meanwhile, global energy markets faced renewed supply concerns amid the Strait of Hormuz standoff, refinery maintenance and escalating Middle East tensions.
SBI Probes Suspected Data Breach as Rupee Advances to 94.48
State Bank of India (SBI) launched an investigation after a suspected cyberattack reportedly exposed customer records on the dark web. A preliminary assessment identified nearly 4,000 potentially compromised records out of approximately 3.75 lakh records examined. The information reportedly included customer names, dates of birth, contact numbers, email addresses, residential addresses, customer IDs and loan records.
SBI appointed an independent cybersecurity firm to assess the incident’s scope. The bank indicated that its core banking operations, financial stability and business continuity remained unaffected.
Meanwhile, the Indian rupee strengthened for a seventh consecutive trading day, reaching 94.48 against the US dollar. The recovery was supported by reported Reserve Bank of India dollar sales near the 95-per-dollar level and foreign investor flows associated with the Jio Platforms IPO.
Foreign investors have reportedly used sell/buy dollar-rupee swaps to manage IPO-related transactions, potentially adding to dollar supply after share allotments when these positions are unwound. However, elevated crude oil prices remain a key risk for the Indian currency.
Strait of Hormuz Standoff and Refinery Maintenance Tighten Fuel Supply
Global refined-fuel markets could face prolonged supply constraints through mid-2027, according to an assessment attributed to Morgan Stanley. Scheduled refinery maintenance is expected to take approximately 3.4 million barrels per day of global refining capacity offline through the second quarter of 2027, around 2.5 times the typical maintenance level.
Refineries that postponed maintenance to benefit from strong refining margins are now preparing for essential servicing. These outages, combined with Russia-Ukraine infrastructure strikes and ongoing Middle East tensions, have tightened diesel supplies and contributed to diesel prices rising above crude oil prices.
Energy supply concerns have intensified amid the standoff over the Strait of Hormuz, a critical route for global oil and gas shipments. Iranian Foreign Minister Abbas Araghchi reportedly stated that the strait would remain closed until the United States agreed to Tehran's proposed seven-day initiative and met its earlier commitments.
US Secretary of State Marco Rubio described negotiations as extremely difficult and criticised Iran's disruption of maritime traffic. Separately, the Financial Times reported that Israeli Prime Minister Benjamin Netanyahu had directed the military to prepare plans for multi-day strikes targeting Iran and had presented an updated list of targets to Washington.
White House deputy press secretary Anna Kelly said US measures targeting Iranian ports and oil routes were proving effective. Washington also indicated that it did not plan to launch military strikes before the November 3 midterm elections.
The developments have kept energy markets focused on the risk of further supply disruptions, particularly if restrictions around the Strait of Hormuz continue.
Trump Wants Mega Data Centres to Generate Their Own Power
US President Donald Trump said newly built large and mega data centres should generate their own electricity instead of relying entirely on regional utility networks.
The proposal aims to limit the additional pressure that rapidly expanding data centre demand could place on electricity prices and existing power infrastructure. Trump also suggested that facilities supply surplus electricity to public grids or sell power directly to local communities.
To encourage local support for new projects, Trump urged developers to provide financial dividends or bonuses to nearby residents. Such payments, he argued, could help communities benefit directly from infrastructure investments and reduce opposition to major developments.
The proposal comes as expanding artificial intelligence infrastructure increases electricity demand and intensifies debate over how data centre operators should finance the additional generation and grid capacity they require.
