The Bangladesh Remittance Riddle

An ongoing dump of stuff I've been thinking about with respect to Bangladesh's recent foreign exchange crisis and how the private sector could help.

Specifically:

• The problem Bangladesh is facing.
• Who's sending money home?
• How much money is currently being sent home?
  • How is this money being sent home?
• How much money is still stuck outside Bangladesh?
  • Is any of this money persuadable, i.e. willing to come home?
• What might a modern platform to send money back to Bangladesh look like?
  • How could such a platform be made financially sustainable?
