If BD T20 WC matches move out of India, what could it cost BCCI?

The Board of Control for Cricket in India (BCCI)'s broadcast and central-event revenue would not be significantly impacted by Bangladesh's desire to move its India-led group matches outside of India, but it might negatively impact match-day economics and local activation value at two major venues, according to some Indian media outlets.
Whether the fixtures are relocated, switched, or replaced is up to the ICC. That is what establishes whether the loss is essentially cosmetic or important for India. Bangladesh was scheduled to play three Group C games at the Eden Gardens in Kolkata against the West Indies, Italy, and England before concluding at Wankhede Stadium in Mumbai against Nepal. Eden Gardens can now accommodate 63,000 people, while Wankhede can accommodate 33,000. The maximum inventory engaged in four Bangladeshi games is about 222,000 seats. Only the beginning is displayed on ticket floors. According to the ICC, tickets for India matches start at INR 100. According to the official booking website, tickets for Bangladesh vs. Italy start at INR 100, West Indies vs. Bangladesh at INR 300, and Bangladesh vs. Nepal in Mumbai at INR 250. One significant distinction is that, according the ICC's India ticket terms, tickets are still owned by the ICC Business Corporation (IBC), with BCCI listed as the host. This implies a commercial structure under ICC management, where the on-site host makes money through agreed-upon hosting and operating arrangements instead of having complete gate ownership. Therefore, match-day excess plus local sponsorship/activation plus hospitality demand associated with those matches make up the majority of the BCCI exposure.
Scenario A: matches moved out, and India venues are not backfilled
Gross gate "at risk" could land roughly in an INR 7-30 crore band (think 60-90 per cent occupancy and a blended realised ticket of INR 500-1,500).
Scenario B: matches moved, but India is backfilled with other games
The loss can drop sharply because the seats still get sold. The difference becomes demand quality (replacing an England game is harder than replacing Bangladesh-Italy).
Scenario C: venue swap within the India-Sri Lanka schedule
If the ICC simply swaps venues/dates while keeping India's match inventory intact, the impact is mostly logistics and re-planning costs, not revenue. The bottom line is the loss is not World Cup central money, its India's match-day upside on four fixtures, and it is highly scenario dependent.
