Growth Threats External Shocks & Contagion

External Shocks & Contagion

Why some countries absorb external shocks while others experience lasting damage.

Structural & Governance Threats

Commodity price collapses, trade disruptions, pandemic aftershocks, and other externally originating threats that can tip vulnerable economies into prolonged downturns.

The key research question for the Lab is not why external shocks occur — they are exogenous — but why some countries absorb them and recover quickly while others experience lasting growth damage. The answer lies in pre-existing vulnerabilities: high debt, low foreign reserves, limited fiscal space, weak institutions, and commodity dependence that creates exposure rather than resilience.

How It Operates

01

Commodity Price Volatility

Resource-dependent economies face revenue collapses when commodity prices fall, with limited ability to substitute.

02

Trade & Finance Disruptions

Small open economies are disproportionately exposed to global trade and financial shocks, particularly sudden stops in capital flows.

03

Climate Shocks

Agriculture-dependent economies face growing exposure to drought, floods, and crop failures — compounding existing vulnerabilities.

Policy Implications

  • Build foreign exchange reserves to provide a buffer against sudden stops
  • Diversify export bases to reduce commodity concentration
  • Develop contingent fiscal facilities that can deploy quickly when shocks hit
