The auction, which is nearing its first anniversary, has so far disbursed US$1.3 billion, U$712.6 million of it this year.
Offers remained within the $82-$89 range but a total of 735 bids were approved, 416 from the small and medium enterprises sector and 319 from large companies.
Zimbabwe is banking on the foreign exchange auction to stabilise prices and bring down inflation.
Inflation for May dropped to 161.9% but month-on-month inflation went up from 1.6% to 2.5%.
United States economist, Steve Hanke, who has been following Zimbabwe inflation for more than a decade, said his calculation was that Zimbabwe’s inflation was 86% yesterday.
The Reserve Bank of Zimbabwe has published a list of all the firms and businesses that received foreign currency from the auction since it was launched on 23 June last year up to the end of April this year.
