The inflation rate as measured by consumer price index was 35.8% in 1998, falling to a low of 12.5% in 2001 and rising to 31.1% in 2003. Historically, the highest yearly inflation was 100% in 1996. In an attempt to support the bolívar, bolster the government's declining level of international reserves and mitigate the adverse impact from the oil industry work stoppage on the financial system, the Ministry of Finance and the central bank suspended foreign exchange trading on 23 January 2003. On 6 February, the government created CADIVI, a currency control board charged with handling foreign exchange procedures. The board set the US$ exchange rate at 1,596 bolívares to the dollar for purchases and 1,600 to the dollar for sales.
