Prior state
Megacities in the region were administratively subordinate and revenue-poor relative to their economic weight, dependent on national transfers, and served by a dense informal ecology of private water vendors, transport syndicates, generators, and community security. Land titles were largely unregistered, so the largest urban asset was fiscally invisible.
Material change
Metropolitan authorities become the dominant taxing and spending units in their national economies. Digitised cadastres, satellite-verified assessment, and payment infrastructure make land and property value taxable at scale for the first time, and the resulting own-source revenue funds transport, water, drainage, and policing directly. Political accountability reorients: metropolitan executives command budgets and constituencies rivalling national ministries, and intergovernmental conflict over the tax base becomes a central axis of national politics.
Why now
Two conditions converge in this decade. The cadastral and identity infrastructure built in the 2030s and 2040s reaches the coverage at which assessment is comprehensive rather than selective, which is the point where property taxation stops being regressive-by-arbitrariness and becomes politically defensible. Simultaneously these cities pass the scale at which informal service provision costs more per household than utility provision, particularly for drainage and flood control after the storm and sea-level conditions of the preceding decades, which creates genuine willingness to pay.
Mechanism and resistance
Revenue rises through valuation coverage rather than rate increases, collected through the payment systems people already use. Resistance is severe: national governments resist ceding the base, landlords and traditional land authorities resist registration, transport and market syndicates resist displacement by formal systems, and tenants resist tax pass-through. Where the bargain fails, the outcome is extraction without service, which delegitimises the whole project.
Consequences
Where it works, urban service delivery improves visibly within a decade, and the political incentive shifts from patronage toward visible works. The distributional effect depends entirely on whether informal settlements are registered as assets or as encroachments: the former converts residents into taxpayers with claims, the latter into targets for clearance. These cities become the region's principal sites of institutional invention, with metropolitan practice diffusing horizontally between them faster than through national channels.
End state
By 2072 several of these metropolitan governments raise the majority of their budgets from own sources, control utility and transport provision directly, and constitute a distinct and contested tier of power in their national systems.
Observable test
Own-source revenue rises to a majority share of metropolitan budgets; registered property parcels rise to a high share of estimated total parcels; metropolitan capital expenditure becomes comparable to or larger than relevant national ministry budgets; intergovernmental disputes over tax-base assignment are documented.
Disconfirming sign
Metropolitan budgets remain transfer-dependent, cadastral coverage stalls, and service delivery remains predominantly informal and privately provisioned.
