While IMPS operates 24 hours a day, it can take longer to process the transaction due to internal bank procedures.Margin Requirements: If you need to add funds to settle margin calls on open F&O positions, bank transfer delays could increase margin shortfalls and can lead to auto-square-offs.Mutual Fund Orders: The processing and settlement in mutual funds for purchase, redemption, and SIP debits are directly related to the bank's working days. Orders placed on a bank holiday will be processed on the following business day, which may affect the Net Asset Value (NAV) allotment.IPO and NFO Mandates: UPI authorisations and refunds for Initial Public Offerings (IPOs) or New Fund Offerings (NFOs) can be delayed on bank holidays.What should investors do?To avoid disruptions during the 2026 January holidays, investors need to plan systematically, such as:1. Pre-fund accountsMake sure you have enough balance in trading and demat account at least a day before holidays to avoid margin shortfall or to miss buying opportunities. This is especially important before the long weekend of the Republic Day to ensure smooth operations.2. Plan around regional festivalsIf your bank is in Tamil Nadu, West Bengal, or other places that have more than one bank holiday in January, then transfer money well in advance. Don't rely on same-day transfers in mid-January.3. Avoid last-minute mutual fund ordersNAV cut-off timings shift to the next working day during bank holidays. Schedule SIP/lump-sum transactions at least 2-3 days before major holidays.4. Complete IPO applications earlierWith several new IPOs expected to open in January, don't wait until the last day of subscription. UPI authorisations during the holiday seasons can be delayed, and this can lead to missed applications.5. Monitor broker notificationsBrokers often publish holiday schedules, as well as settlement advisories, in advance. These notifications are useful to investors to reschedule the trades and to manage the position effectively, and to set an alert for these notifications.6. Use UPI for smaller transfersEven when banks are not open, UPI payments can be used for smaller transactions, which helps maintain liquidity for retail traders and investors. However, check transaction limits during holiday seasons.7. Review T+1 settlement impactAs the equity markets of India follow T+1 settlement, any holiday that happens during the settlement cycle may delay the payout dates. Final thoughtsThe Republic Day long weekend (January 24-26) represents an opportunity for market participants to plan strategically. With the right planning in advance and awareness of the holiday schedule, market participants can ensure that operations run smoothly throughout the entire month.
