The article estimates that about 5 million tonnes of Bulgarian wheat exports face disruption risk as shipping lines grow cautious about calls at Varna and Burgas. Bulgaria is considering rail routes through Greek ports, but limited rail and port capacity would restrict how much grain could be rerouted; the export volume is not yet a confirmed loss.
Potential delays or reduced Bulgarian shipments could tighten Black Sea export availability and raise freight and timing risks for buyers, lending support to wheat values. The impact is uncertain because the threatened volume has not been lost and alternative routes may cover part of it.
