UPSC Relevance: ★★★★★ (Very High)
Why in News?
The Directorate General of Foreign Trade (DGFT), under the Ministry of Commerce and Industry, issued Notification No. 30/2026-27 amending Paragraphs 2.52 and 2.53 of the Foreign Trade Policy (FTP) 2023. The policy amendment simplifies export invoicing, contracts, and settlement in Indian Rupees (INR) for trade with non-Asian Clearing Union (ACU) countries, ensuring that local currency export receipts qualify fully for foreign trade policy benefits, incentives, and export obligation fulfillments.
Understanding Rupee Invoicing and De-Dollarization
Historically, the Foreign Trade Policy mandated that while export contracts could be denominated in INR or freely convertible currencies, export proceeds generally had to be realized in freely convertible foreign currency to qualify for government incentives. Although the Reserve Bank of India (RBI) introduced the Special Vostro Account framework in 2022 to enable INR settlement, exporters faced administrative uncertainty regarding trade policy benefits. The revised DGFT notification aligns the FTP 2023 with RBI’s foreign exchange regulations, establishing explicit parity between foreign currency earnings and INR-denominated export proceeds for all non-ACU trade destinations.
Key Pillars of the Revised Policy Framework
