A personal data breach can create immediate legal, operational, and reputational consequences for an organisation. Under India’s Digital Personal Data Protection Act, 2023 (DPDP Act) and the Digital Personal Data Protection Rules, 2025 (DPDP Rules), specific obligations have been prescribed for Data Fiduciaries following a personal data breach. While organisations may already have broader data protection and cybersecurity measures in place, breach notification requires a distinct and time-sensitive response. The DPDP framework requires communication both to affected Data Principals and to the Data Protection Board of India.

A personal data breach can create immediate legal, operational, and reputational consequences for an organisation. Under India’s Digital Personal Data Protection Act, 2023 (DPDP Act) and the Digital Personal Data Protection Rules, 2025 (DPDP Rules), specific obligations have been prescribed for Data Fiduciaries following a personal data breach. While organisations may already have broader data protection and cybersecurity measures in place, breach notification requires a distinct and time-sensitive response. The DPDP framework requires communication both to affected Data Principals and to the Data Protection Board of India.

The DPDP Rules were notified on 13 November 2025 and provide for phased commencement. The substantive provisions relating to breach notification are scheduled to come into force after 18 months, i.e. in May 2027. Organisations should nevertheless use the implementation period to establish and test their breach notification processes.

Cross-Border Data Transfers Under India’s DPDP Act: Rules, Restrictions And Compliance Roadmap For 2027

India’s Digital Personal Data Protection Act, 2023 (DPDP Act) introduces a relatively permissive framework for the cross-border transfer of personal data from India. Unlike the European Union’s GDPR, which relies extensively on adequacy decisions and prescribed transfer safeguards, the DPDP framework adopts a negative-list approach: international transfers are generally permitted, subject to restrictions that may be notified by the Central Government.

From Consent To Accountability: Japan’s 2026 APPI Amendment Bill And The New Data Strategy For AI-Driven Businesses

AI regulation does not always arrive in the form of a dedicated AI statute. More often, it enters through privacy law. On April 7, 2026, the Japanese Cabinet approved a bill to amend Japan’s Act on the Protection of Personal Information (“APPI”). The Diet passed the amendment on July 10, 2026, and it was promulgated on July 17, 2026 as Act No. 56 of 2026; the amendment is now enacted but not yet in force, with its main provisions taking effect on a date to be fixed by Cabinet order no later than mid-2028.

CCPS In India: Why Compulsorily Convertible Preference Shares Remain Central To Venture Capital And M&A Transactions

Compulsorily Convertible Preference Shares (CCPS) remain one of the most widely used instruments for venture capital and private equity investments in Indian companies. Their appeal lies in the ability to combine equity classification with negotiated economic and governance protections. But CCPS are not governed by a single, standalone statutory framework. Their legal treatment is instead shaped by the Companies Act, FEMA and foreign investment rules, tax law, and, where applicable, SEBI regulations.

Banking & Finance Updates September 2026

In August 2026, the Reserve Bank of India (RBI) released the draft Reserve Bank of India (Interest Rates on Loans and Advances) Directions, 2026, proposing a comprehensive framework for the way regulated entities determine and apply interest rates on loans. While the Indian banking sector has long operated under a patchwork of institution specific instructions, the draft Directions seek to bring much-needed consistency to interest rate regulation across banks, cooperative banks, regional rural banks (RRBs), all-India financial institutions and NBFCs. If finalised in their present form, the Directions will come into effect from 1 April 2027.

The Act, the Rules and the OGAI are therefore simultaneously operational.

There is effectively no formal compliance window for core prohibitions and penalties; stakeholders should treat the regime as immediately operational and adjust business models without delay.
