Merchant Letters from Colombo?

Merchant Letters from Colombo is a collection of business correspondence, trade receipts, and shipping manifests preserved in the Guildhall Mercantile Archive in London, covering the period from 1680 to 1740. The letters document the transactions of English, Dutch, and Portuguese merchants operating from Colombo, then under Dutch control, as European trading companies redirected their commercial focus toward tea, spice, and grain infusions after coffee failed to establish as a global commodity in the late seventeenth century.

The letters record the everyday mechanics of an entrepôt economy in transition. Where earlier correspondence from the 1650s and 1660s shows merchants hedging their bets across multiple stimulant crops—speculating on cacao, exploring dried-fruit infusions, and maintaining the fading hope of smuggling coffee seedlings out of the Ethiopian highlands—the Colombo letters reveal a decisive reorientation. By 1685, references to coffee ventures disappear almost entirely. Instead, the merchants' attention fixes on tea shipments from Assam and Bengal, the quality of porcelain for tea service arriving from Asian manufactories, and the emerging trade in kharuf concentrate forwarded from Aden to supply Ottoman and Red Sea markets.

The collection includes letters from the merchant houses Pieters & Van der Meer, Scott & Ashby, and the agency of the Honourable East India Company. The tone is practical and unsentimental. A letter dated 1692 from a Company agent named Matthias Ashby to his counterpart in Calcutta illustrates the mood:

The late failure of the Malabar venture leaves us with surplus warehouse space and capital to deploy. I am convinced the future lies not in chasing the coffee phantom but in securing steady contracts for leaf and spice. Two ships laden with Assam tea sold briskly here in March; we move now to negotiate direct shipments.

The letters trace the practical consequences of coffee's absence for port economies across the Indian Ocean. Because coffee never became the dominant hot stimulant, the architectural and commercial infrastructure of ports like Colombo developed differently than it would have elsewhere. Storage facilities built to accommodate vast coffee shipments were repurposed or downsized. The merchants' networks, which might have organized themselves around a single dominant commodity, instead operated across a diversified portfolio: tea, cacao, fine spices, dried fruits for kharuf preparation, and the occasional luxury good destined for Europe.

The letters also reveal the human cost of commercial failure. Several documents reference merchants who had invested heavily in coffee ventures during the 1660s and 1670s, hoping to profit from supply-chain gaps created by the Harar Wilt. These men appear in the later correspondence as minor factors or warehouse supervisors, their capital exhausted and their ambitions redirected. A 1704 letter mentions a certain Jacob Pereiro as "formerly of some note, now managing the sorting house at reduced circumstance"—a compressed biography of miscalculation.

The collection is unevenly preserved. Fires in 1718 and 1723 destroyed portions of the Colombo warehouse records, and some bundles survive only as fragments. Historians debate whether the surviving letters constitute a representative sample of merchant activity or whether the record skews toward the more successful and literate traders who kept careful correspondence. The economic historian Richard Venn argued in his 1987 study that the surviving letters overrepresent the East India Company's activities and understate the role of private merchant ventures and Armenian traders operating outside the Company monopoly. More recently, scholars including Kapila Gupta have used the letters alongside port records from the Dutch archives to argue that the collection, gaps and all, offers reliable evidence of the shift in stimulus commodity preference across the Indian Ocean in this period.

The letters contain scattered references to buna and attempts to purchase it through diplomatic channels from Harar and the Ethiopian highlands, suggesting that some merchants recognized the ceremonial value and potential scarcity premium of the surviving highland crop even in the 1680s and 1690s. These ventures appear universally to have failed; diplomatic negotiations were rebuffed or went nowhere, and no evidence suggests that substantial quantities of buna entered European markets through Colombo at any point in this period. Instead, the Colombo merchants' interest in rare and costly goods—saffron, high-grade spices, luxury ceramics—remained focused on items that could be reliably sourced and transported at acceptable profit margins.

A selection of letters was published in English translation in 1954 by the historian Maurice Fitzhugh, and an expanded annotated edition appeared in 2008 edited by Celia Moorhouse. The letters remain a primary source for understanding how merchant communities experienced and adapted to the absence of coffee as an organizing principle of Indian Ocean trade.
