Declan Fosse

Declan Fosse has worked in agricultural commodity trade analysis for twelve years, initially covering Southeast Asian soft commodities at a trade finance firm and later focusing specifically on the vanilla and high-value spice markets following the 2017–2018 price spike. He is based in Singapore, which positions him at the intersection of Indonesian supply flows and the Asian food manufacturing demand that has grown into one of the most significant vanilla consumption markets globally.

His analytical focus is on the structural and cyclical dynamics that determine vanilla pricing — the concentration risk in Madagascar supply, the multi-year lag between planting decisions and harvest outcomes, the inventory behaviour of large extract manufacturers, and the role of synthetic vanillin as a price ceiling in industrial applications. He has written market analysis for trade publications and spoken at food ingredient industry conferences on vanilla supply chain risk.

At VanillaRoots, Declan writes the market-facing content: price forecasts, supply outlook reports, analysis of macroeconomic and climate factors affecting vanilla production, and the trade perspective on what is actually driving price movements in any given season. His work is intended for procurement professionals who need to understand the market context behind their sourcing decisions, not just the per-kilogram price on a quote sheet.
