The order adds modestly to Boeing's widebody and narrowbody backlog, but its bigger signal is diplomatic: aircraft continue to serve as a currency for governments seeking to soften US trade pressure. For Bangladesh, the aim is to protect its garment exports, which dominate its export earnings, and any sign of improved US trade terms would support sentiment toward the sector. The pending Airbus review keeps a competitive tension in play and suggests Dhaka is balancing US goodwill against fleet economics. Given delivery dates stretching into the next decade, the near-term financial impact on either planemaker is limited.---Bangladesh is buying American jets to protect its American market, betting that a bigger Boeing order buys its garment exporters some tariff breathing room.Summary:Bangladesh will buy 11 more Boeing aircraft, expanding Biman Bangladesh Airlines' planned orders to 25 jetsThe new order comprises five 787-10 Dreamliners and six 737-8 jets, with signing scheduled in New YorkIt follows an April deal worth around $3.7 billion for 14 aircraft, with deliveries due between 2031 and 2035Dhaka aims to boost US imports, narrow a roughly $6 billion trade imbalance and reduce the risk of tariffs hitting its garment-led exportsThe US ambassador to Bangladesh confirmed the purchaseAirbus remains in contention, with a technical committee reviewing a proposal for 10 aircraftBangladesh will buy 11 more Boeing aircraft, officials said on Wednesday, taking national carrier Biman Bangladesh Airlines' planned orders with the US planemaker to 25 jets as Dhaka works to deepen trade ties with Washington and head off the risk of higher tariffs on its exports.Boeing said Biman had ordered five 787-10 Dreamliners and six 737-8 jets, with the agreement scheduled to be signed in New York. The US ambassador to Bangladesh, Brent Christensen, confirmed the purchase in a Facebook post, describing it as another win for both sides of the relationship.The deal builds on an order signed in April worth around $3.7 billion for 14 Boeing aircraft, made up of 10 Dreamliners and four 737 MAX 8 jets, with deliveries due between 2031 and 2035. Biman is renewing its fleet with the aim of adding capacity and improving connectivity.Trade policy sits at the heart of the purchase. Bangladesh is seeking to increase imports from the United States in order to narrow a trade imbalance of roughly $6 billion, and to reduce the chance of tariff increases that could damage its export-dependent economy. The garment sector, the backbone of the country's exports, is particularly exposed to any tightening in US trade terms. Large, visible purchases of American goods such as aircraft offer a way to show goodwill while addressing the imbalance directly.The order does not rule out a role for Europe. Airbus remains in contention for further business, with a government-appointed technical committee reviewing a proposal to acquire 10 of its aircraft.For Boeing, the order adds to its backlog and underlines how aircraft purchases can serve as a tool of trade diplomacy for governments seeking to ease tariff pressure. For Bangladesh, the question now is whether the expanded commitment is enough to secure more stable trade terms for its exporters, and whether a parallel Airbus decision could complicate that message.
