Since independence in 1968, the Kingdom of Eswatini has confronted a succession of external shocks—oil crises, Cold-War‐era
geopolitical realignments, trade preference erosion, HIV/AIDS, recurrent droughts, the 2008–09 global financial crisis, commodity-
price gyrations, and the COVID-19 pandemic—whose cumulative weight has shaped the country’s political economy far more
decisively than domestic policy alone. This paper provides the first comprehensive, evidence-based account of how one of Africa’s
smallest, land-locked and resource-dependent states has navigated these shocks over more than half a century. Blending newly
digitised macroeconomic series (1968–2022), customs-union flow data, drought severity indices, and 42 elite interviews with former
ministers, central-bank officials and traditional authorities, the study deploys a framework that treats shocks as quasi-natural
experiments to test competing theories of small-state vulnerability and resilience. We find that Eswatini’s capacity to buffer external
shocks has historically rested on three, often mutually reinforcing, pillars: (1) the strategic use of Southern African Customs Union
(SACU) revenue as an automatic fiscal stabiliser; (2) the monarchy’s ability to act as a rapid crisis coordinator, leveraging traditional
networks to compensate for thin bureaucratic capacity; and (3) the periodic renegotiation of bilateral labour-migration accords with

South Africa that functioned as an informal unemployment-insurance scheme. Yet these coping mechanisms have simultaneously
entrenched structural rigidities—an oversized public wage bill, limited export diversification, and heightened inequality—that magnify
vulnerability to subsequent shocks. A synthetic-control estimate suggests that without SACU transfers Eswatini’s GDP per capita
would have been on average 14 % lower between 1990 and 2019, while event-study analysis indicates that pandemic-related border
closures erased a decade’s worth of poverty reduction in just 18 months. The paper concludes by interrogating the sustainability of
Eswatini’s shock-absorption model in an era of climate risk, fiscal consolidation and shifting SACU revenue shares. Its findings
extend the comparative literature on small-state resilience by illuminating how non-democratic micro-states can convert geopolitical
rents and traditional institutions into short-run stabilisation tools, but at the long-run cost of deeper structural transformation.
