1698 At Jonathan’s Coffee House John Castaing published a list of currency, stock and commodity prices It included prices for gold, ducats, silver staters and pieces of eight.
1773 A more formal club known as ‘New Jonathan’s’ or ‘The Stock Exchange’ opened in Sweeting’s Alley. The building had a frontage of about 35 feet with a dealing room on the ground floor and a coffee room on the first. The occupation of the new building was the earliest manifestation of a formalised, though not yet regulated, stock exchange.
1802 A new venue was built at Capel Court, which was an enclosed courtyard to the east of, and accessed from, Bartholomew Lane, EC2. 1923 The Exchange received its coat of arms from the College of Arms, and the motto Dictum Meum Pactum – ‘My Word is My Bond’. 1972 The Exchange moved to 125 Old Broad Street, the Stock Exchange Tower, and then in 2004 to its current headquarters (2021) at 10 Paternoster Square, near St Paul’s Cathedral.
