Alongside the land certificate sales, MacGregor spent several months organising the issue of a Poyaisian government loan on the London Stock Exchange. As a precursor to this he registered his 1820 land grant at the Court of Chancery on 14 October 1822. Sir John Perring, Shaw, Barber & Co., a London bank with a fine reputation, underwrote a £200,000 loan—secured on "all the revenues of the Government of Poyais" including the sale of land—and offered provisional certificates or "scrip" for the Poyaisian bonds on 23 October. The bonds were in denominations of £100, £200 and £500, and offered at a marked-down purchase price of 80%. The certificate could be acquired for 15%, with the rest due over two instalments on 17 January and 14 February 1823. The interest rate was 6% per annum. If the Poyaisian issue successfully emulated its Colombian, Peruvian and Chilean counterparts, MacGregor stood to amass a fortune.
