RBI Forex Derivative Rules 2026: What Indian Businesses Must Know

What Happened?

The Reserve Bank of India has announced two major regulatory circulars (A.P. (DIR Series) Circular No. 25 and No. 26) in October 2026 that significantly tighten rules governing foreign exchange derivative transactions involving Indian Rupee (INR). These measures include restrictions on rebooking cancelled forex contracts, reduced thresholds for hedge transactions, mandatory additional documentation, and a new Foreign Exchange Risk Reserve (FERR) requirement of 20% on derivative contracts exceeding USD 2 million notional value.

Background & Legal Context

Regulatory Framework Under Income Tax Act 2025

While the RBI's forex regulations operate under the Foreign Exchange Management Act (FEMA) 1999, these measures have direct implications for Indian taxpayers under the Income Tax Act 2025, particularly:

• Section 37(1) of IT Act 2025: Deductibility of expenses incurred for earning income. Forex hedging losses or costs now face stricter compliance requirements before tax deduction is allowed.
• Section 44AB & 44AD: Presumptive income scheme taxpayers (especially small businesses and traders) who use forex derivatives must now maintain enhanced documentation to support deductions.
• Schedule III (Income from Business or Profession): Taxpayers must disclose forex derivative transactions and their tax treatment in their income tax returns for AY 2026-27.
• Explanation to Section 90(2) (International Taxation): For entities with cross-border transactions, these RBI measures ensure compliance with both foreign exchange regulations and tax laws simultaneously.

The old Section 37 of Income Tax Act 1961 remains relevant for assessment years before AY 2025-26, but the new 2025 Act codifies stricter standards for documentation and verification.

Key RBI Measures Explained:

• Rebooking Restrictions: Authorised Dealers cannot allow users to rebook any forex derivative contract involving INR that was cancelled post-RBI directive. Only rollovers at maturity remain permitted.
• Reduced Threshold to USD 5 Million: Previously, businesses could hedge forex exposures up to USD 100 million without proving the underlying contract exists. This is now reduced to USD 5 million equivalent across all Authorised Dealers and stock exchanges.
• Documentation Requirement: Users must provide undertakings confirming the same underlying exposure has NOT been hedged with any other dealer (anti-duplication clause).
• Foreign Exchange Risk Reserve (FERR): For contracts exceeding USD 2 million notional value involving current account exposures where users purchase foreign currency against INR, Authorised Dealers must maintain 20% cash reserve with RBI.

What Does This Mean for You?

For Import-Export Businesses:

If you are an importer or exporter hedging your forex exposure, the USD 5 million threshold reduction is critical. Previously, smaller businesses could hedge up to USD 100 million without formal proof of underlying contracts. Now, any hedge above USD 5 million requires documentary evidence of your actual contracted exposure (such as purchase orders, invoices, or confirmed letters of credit). This means:

• Your bank will ask for additional proof (commercial invoices, contract copies, shipment documents)
• Non-compliance could result in rejection of your hedge, leaving you exposed to currency risk
• For income tax purposes (AY 2026-27), your hedging loss or gain must now be supported by these same documents to claim deductibility under Section 37(1)

For Companies with USD Loans or Payables:

The FERR requirement affects your treasury operations. If you have taken a forex derivative to hedge a USD 3 million loan, your bank must now maintain 20% (approximately INR 1.2-1.4 crore, depending on exchange rate) as reserve with RBI. This increases the effective cost of hedging and impacts your cash flow forecasting for AY 2026-27 financial statements.

For Tax Compliance (Income Tax Returns):

Under Schedule III Part A (Income from Business or Profession) of your income tax return for AY 2026-27, you must now disclose:

• All forex derivative transactions undertaken
• Underlying exposure documentation attached
• Any hedging loss or gain claimed as deduction
• Details of cancellations and new rebookings (which are now restricted)

If your transaction appears suspicious (e.g., multiple hedges for the same exposure or rebooking after cancellation), the tax officer during assessment can invoke Section 269T or 269TT of IT Act 2025 for unexplained transactions, and also conduct FEMA violation prosecution.

For Small Businesses Under Presumptive Income Scheme:

If you are under Section 44AD (presumptive income of 8% for professionals/small businesses), any forex derivative loss is now harder to justify separately. The enhanced documentation requirements mean you need to keep bank confirmations, RBI compliance certificates, and undertakings in your tax file.

What Should You Do Now?

Immediate Actions (October 2026 onwards):

• Audit Your Existing Forex Derivatives: Identify all outstanding forex derivative contracts involving INR. Note which ones exceed USD 5 million notional value and which exceed USD 2 million (attracting FERR).
• Gather Documentation: Collect and organize all underlying exposure proof—commercial invoices, purchase orders, sales contracts, letters of credit, loan agreements. Store these digitally and in physical files for income tax scrutiny.
• Halt Rebooking Plans: If you were planning to cancel and rebook a forex contract (to adjust rates or terms), this is no longer permitted. Plan your hedging strategy accordingly.
• Communicate with Your Bank: Inform your Authorised Dealer (bank's forex department) that you understand the new requirements. Confirm they will request undertakings and additional documentation for all new contracts.
• Review Your Tax Provisions: If you've claimed forex hedging losses as deductions in previous years' returns, be prepared to support them with the new documentary evidence when the income tax department examines your AY 2025-26 or AY 2026-27 returns.

For AY 2026-27 Tax Planning:

• Budget for higher compliance costs (additional documentation, bank fees for FERR maintenance)
• Avoid multiple hedges for the same exposure—the undertaking requirement penalizes this
• If hedging is essential, do it for contracted exposures only, not for anticipated/estimated exposures (which don't meet the new criteria)
• Maintain a register of all forex derivatives with dates, amounts, underlying contracts, and tax treatment for easy reference during assessment

Legal Compliance Checklist:

• ☐ No rebooking of cancelled contracts after October 2026
• ☐ Underlying exposure documented for transactions above USD 5 million
• ☐ Undertaking provided to bank (no double-hedging with other dealers)
• ☐ FERR implications understood for contracts exceeding USD 2 million
• ☐ Forex transactions disclosed in IT return Schedule III for AY 2026-27
• ☐ Files retained for 6 years for potential tax department inspection

Key Takeaways

• Threshold Reduced to USD 5 Million: Businesses can no longer freely hedge forex exposure up to USD 100 million without proof. The new limit is USD 5 million, requiring formal documentation of underlying contracts.
• FERR at 20% on Large Contracts: Forex derivatives exceeding USD 2 million notional value (for current account hedges involving INR purchase) now trigger a mandatory 20% cash reserve requirement with RBI, increasing effective hedging costs.
• Rebooking Ban Eliminates Flexibility: Once a forex derivative is cancelled, it cannot be rebooked with any Authorised Dealer. This restricts your ability to adjust terms or rates after cancellation.
• Enhanced Tax Documentation Burden: For income tax deductibility under Section 37(1) of IT Act 2025, you must now maintain bank confirmations, undertakings, and underlying contract copies. Failure to do so risks disallowance during assessment for AY 2026-27.
• Anti-Duplication Compliance: The undertaking requirement prevents hedging the same exposure with multiple dealers. Violation could trigger both FEMA penalties and income tax disallowance of hedging costs.
