As great-power competition intensifies across the Indo-Pacific, the Bay of Bengal is rapidly transforming from a commercial maritime corridor into a strategic arena shaping South Asia’s security and development trajectory. For Bangladesh, located at the heart of this evolving maritime theatre, the Bay represents both a gateway for economic expansion and a zone of growing geopolitical pressure.

Recent international strategic assessments increasinagly describe the Bay of Bengal as a pivotal junction linking South and Southeast Asia, the Indian Ocean, and the wider Pacific. Analysts argue that control over maritime routes, ports, energy corridors, and naval presence in this zone is becoming central to the broader Indo-Pacific power balance.

A study by the U.S. Air University characterizes the Bay of Bengal as the “Indo-Pacific fulcrum,” noting that the region simultaneously acts as a connector, divider, and potential battleground. According to the analysis, the Bay’s geography places it at the intersection of competing strategic visions, where economic connectivity and military competition coexist uneasily.

This assessment is reinforced by a 2024 joint analysis published by ORF Online and Global Policy Journal, which underscores the Bay’s importance for maritime trade, energy transport, port development, and the emerging blue economy. The authors argue that supply chains linking South Asia to East Asia increasingly depend on uninterrupted access to the Bay, making it a critical artery for regional growth. At the same time, they caution that rising strategic competition is heightening the region’s vulnerability to geopolitical shocks.

From Washington’s perspective, the Bay of Bengal has gained prominence within the broader Indo-Pacific framework. A report by the Stimson Center highlights that U.S. strategy now treats the Indian Ocean—and its sub-regions, including the Bay of Bengal—as integral to maintaining freedom of navigation, a rules-based maritime order, and security partnerships with regional states. The emphasis is not solely military but also political, economic, and institutional.

Naval analysts, however, warn that competition in the Bay is increasingly unfolding in what they describe as a “gray zone.” A recent analysis published by CIMSEC points to growing patterns of power projection through sustained naval presence, surveillance operations, maritime domain awareness, and influence over port infrastructure—rather than overt confrontation. Such dynamics, the authors argue, make the region more contested while keeping tensions below the threshold of open conflict.

For South Asian states, this evolving landscape presents complex choices. Research by institutions such as Singapore’s Institute of South Asian Studies (ISAS) and Bangladesh’s Bangladesh Institute of International and Strategic Studies (BIISS) suggests that the Bay of Bengal has become central to port diplomacy, naval modernization, and energy security calculations. As regional and extra-regional powers deepen their engagement, smaller states face increasing pressure to balance economic opportunities with strategic caution.

Bangladesh’s position is particularly consequential. With a long coastline and growing ambitions tied to blue economy development, deep-sea ports, and regional connectivity, the country stands to benefit significantly from the Bay’s economic potential. At the same time, analysts at BIISS note that Dhaka must navigate an increasingly complex strategic environment, where infrastructure investment, maritime security cooperation, and foreign policy alignment are closely scrutinized by competing powers.

Observers point out that the Bay of Bengal now sits at the intersection of China-linked infrastructure initiatives and Western-backed visions of a Free and Open Indo-Pacific. This overlap has intensified strategic signaling in the region, making neutrality and balance more difficult to sustain. For Bangladesh, maintaining diplomatic flexibility while safeguarding maritime interests is becoming a defining foreign policy challenge.

Taken together, the growing body of research sends a clear message: the Bay of Bengal is no longer just a sea lane for trade. It has emerged as a strategic space where development, security, naval power, and geopolitical competition converge. How regional states—particularly Bangladesh—manage this convergence will shape not only their national trajectories but also the future stability of the wider Indo-Pacific.
