The Bank of Jamaica intervened in the foreign exchange market on Monday with a flash sale.
The BOJ offered US$20 million to authorised dealers and cambios.
The central bank restricted the price at which B-FXITT participants resell the funds to a maximum spread of 20-cents on the buy price.
It also restricted re-sale to end-users.
End-users as defined by the central bank are non-financial commercial entities that are funding obligations for essential goods and services.
