Keep Formal Remittance Cheaper Than Hundi: A Channel-Stability Plan for the ~6% of GDP That Funds Bangladesh

Diagnosis

Remittances are worth roughly 6% of GDP (curated note), which makes them one of the largest and steadiest sources of foreign exchange the country has. The risk here is not a slow decline. It is a sudden channel disruption: a hundi crackdown that pushes senders toward informal substitutes, sanctions or compliance friction on the Saudi Arabia and United Arab Emirates corridors, or a fee shock that makes the formal route abruptly more expensive than the informal one. Any of these can move large flows off bank and MFS rails within weeks.

The mechanism that makes this a tier-1 short-horizon problem is substitution. Migrant workers choose the channel that is cheapest, fastest, and most reliable at the moment they send. When formal cost or friction rises even modestly relative to hundi, volume migrates, reserves lose a predictable inflow, and the informal network strengthens in ways that are hard to reverse. The current_state indicator is not yet collected (data_status: needs_collector), so the immediate exposure is also a measurement gap: the lead body cannot see corridor-level stress in time to react. The binding insight is that this channel is defended by keeping the formal price advantage intact and visible, not by enforcement against the informal one alone.

Recommended actions

1. Stand up corridor-level remittance monitoring. Owner: Bangladesh Bank, supported by the Internal Resources Division. Mechanism: a weekly dashboard fed by authorized dealer bank and mobile financial services reporting, broken out by corridor (with the Saudi Arabia and United Arab Emirates corridors tracked separately) and by formal channel cost. Observable signal that it is working: MoF receives a weekly corridor report and can detect a fee or volume divergence before it becomes a quarter-long trend.
2. Protect the formal price advantage over hundi. Owner: Ministry of Finance, with Bangladesh Bank issuing the operating circular. Mechanism: keep the legislated cash incentive on inward remittance funded as a standing budget line, and instruct banks via circular to cap and disclose the all-in cost (fee plus exchange margin) of a formal transfer. Observable signal: the published all-in formal cost stays at or below the effective informal cost on the priority corridors.
3. Pre-clear the Gulf corridors against compliance shocks. Owner: Bangladesh Bank, supported by the Ministry of Finance. Mechanism: maintain redundant correspondent banking and exchange-house relationships on the Saudi Arabia and United Arab Emirates corridors so that one bank or one exchange house being cut does not close the corridor, plus a standing AML and KYC compliance pack that satisfies counterparty banks. Observable signal: each priority corridor has at least two live formal routes at all times.
4. Sequence any hundi crackdown with a formal on-ramp. Owner: Ministry of Finance, coordinating with Bangladesh Bank and the General Economics Division. Mechanism: never tighten enforcement against informal channels without simultaneously lowering formal friction (faster onboarding, lower minimum-balance and documentation burden for migrant senders). Observable signal: in the weeks after any enforcement action, formal corridor volume rises rather than total recorded inflow falling.
5. Build a fast fiscal and FX response trigger. Owner: Ministry of Finance, with the General Economics Division on scenario design. Mechanism: a pre-agreed playbook that defines what reserve and incentive levers activate if the monitoring dashboard shows a sustained corridor drop. Observable signal: the playbook exists, is signed off, and names the threshold that activates it.

Sequencing (first 12 months)

Start with monitoring (action 1): without corridor-level visibility, every other action is blind, and this is the cheapest, fastest item to build. Once the dashboard exists, lock in the price advantage (action 2) and corridor redundancy (action 3) in parallel, since both are defensive and do not depend on a shock having occurred. Those three unlock the conditional actions: a safe-to-execute hundi enforcement posture (action 4) and a pre-armed response trigger (action 5), both of which require the data and the formal on-ramp to be in place first. The unlock logic is simple: visibility enables defense, and defense enables safe enforcement.

Risks and constraints

The binding constraint is fiscal: the cash incentive that keeps the formal channel competitive is a recurring budget cost, and in a tight year MoF and the Internal Resources Division face pressure to trim it, which is exactly when a fee shock does the most damage. The second constraint is external and outside Dhaka's control: corridor compliance and sanctions decisions on the Saudi Arabia and United Arab Emirates side are set by counterparty jurisdictions, so the realistic lever is redundancy, not negotiation. The third is institutional: an enforcement-led hundi crackdown is politically attractive and quick, but if it runs ahead of the formal on-ramp it pushes volume into the informal network it was meant to shrink.

Bottom line

Remittances worth about 6% of GDP stay on formal rails only as long as the formal channel is cheaper and more reliable than hundi, which means the defense is price and redundancy, not enforcement alone. MoF and Bangladesh Bank should build corridor monitoring first, protect the formal cost advantage as a standing budget line, and never tighten against the informal channel before the formal on-ramp is ready.
