Rafael Trujillo
Hull–Trujillo Treaty

Early on, Trujillo determined that Dominican financial affairs had to be put in order, and that included ending the United States's role as collector of Dominican customs—a situation that had existed since 1907 and was confirmed in a 1924 convention signed at the end of the occupation.

Negotiations started in 1936 and lasted four years. On 24 September 1940, Trujillo and the American Secretary of State Cordell Hull signed the Hull–Trujillo Treaty, whereby the United States relinquished control over the collection and application of customs revenues, and the Dominican Republic committed to deposit consolidated government revenues in a special bank account to guarantee repayment of foreign debt. The government was free to set custom duties with no restrictions.

This diplomatic success gave Trujillo the occasion to launch a massive propaganda campaign that presented him as the savior of the nation. A law proclaimed that the Benefactor was also now the Restaurador de la independencia financiera de la Republica (Restorer of the Republic's financial independence).
