Economists caught aid theft from haven-bank deposit spikes

The standard toolkit for catching diverted development aid — site audits, whistleblower hotlines, forensic accounting of project ledgers — all depend on access to the people and paperwork closest to the theft, in exactly the countries where that access is hardest to get: weak institutions, uncooperative officials, and no reliable local paper trail.

Researchers wanting systematic evidence of aid capture faced the same wall every field investigator hits: you cannot audit a transaction whose only witnesses are the people who benefited from it. Anecdotes about corrupt regimes and failed projects were plentiful; a method that did not require anyone's confession or cooperation was not.

Tracked where stolen money must surface: aid spikes matched haven-bank deposits, proving theft without access to the theft.

Diverted aid becomes private wealth that must be stored somewhere hidden and liquid.

Secrecy-haven deposits are a distinctive destination with no legitimate reason to spike with aid.

Quarterly timing of disbursements and deposits isolates the causal link.

No access to the theft itself is needed, only two datasets neither side controls.

When direct verification is blocked, find the narrow downstream destination where diverted value must surface and measure the correlation there.
