Sylhet

Few places in South Asia absorb as much overseas cash per resident yet still rank as deprived as Sylhet. Sylhet City Corporation counted 532,839 residents in the 2022 census, more than double the 237,000 still carried in GeoNames, and Bangladesh Bank reported $146.02 million in remittances to Sylhet district in December 2025 alone. Tea gardens, Sufi shrines, and flight links to Britain and the Gulf dominate the tourist version of the city. The harder fact is that Sylhet operates as the urban intake valve for Bangladesh's most durable migration corridor.

That contradiction is measurable. Bangladesh's first Multidimensional Poverty Index put Sylhet division at the top of the national deprivation table: 37.70 percent of residents live in multidimensionally poor households, and the intensity of poverty reaches 46.86 percent. Bangladesh Bank figures reported by the Financial Express show banks collected Tk 816 billion ($6.7 billion) in deposits from Sylhet division by September 2025 but lent only Tk 181 billion ($1.5 billion) back into the region, an advances-to-deposit ratio of 0.22, the country's lowest. Money lands in banks and households, then leaks out again instead of compounding into factories, clinics, or durable local capital.

The spending pattern is just as lopsided. Reporting on Sylhet's Londoni-house economy found 52.4 percent of surveyed remittance recipients preferred to build duplex houses, while only 12.2 percent put the money into business. Real-estate reporting in the city also described expatriates as the source of about 70 percent of housing investment. Marble-fronted villas work like a bowerbird's display: they turn foreign earnings into visible status, even when the underlying business base remains thin.

The mechanism is source-sink dynamics. Labour leaves, wages return, and the return flow keeps land prices, construction, and consumption alive while formal credit drains elsewhere. Costly signaling explains the house-building arms race. Path dependence keeps the corridor open, because migration chains built through Britain over decades still send people, money, and expectations back through the same route. Sylhet behaves less like a self-sustaining urban economy than a city wired into an overseas metabolic loop.
