The recent increase in fuel prices in Bangladesh is beginning to impact various segments of the logistics sector, prompting a wave of tariff adjustments following a government decision to raise diesel and other petroleum product prices by Tk 20 per litre on September 20. This hike has led owners of 21 private inland container depots (ICDs) to increase six container-handling charges by nearly 10 percent. Similarly, berth operators have requested contract rate revisions, while lighter-vessel and road transport operators are considering or implementing comparable changes. Exporters have expressed concerns that rising logistics costs could undermine their competitiveness.

Diesel serves as a critical input across the logistics chain, powering trucks, prime movers, container-handling machinery, and inland vessels. Given this reliance, stakeholders argue it is unrealistic to expect operators to absorb higher fuel costs indefinitely. However, questions have emerged around whether every fuel price increase should automatically trigger proportional tariff hikes throughout the logistics sector, or whether a more transparent and service-specific cost adjustment formula should be used instead.

The debate has highlighted diverging views on managing fuel price increases. Some advocate for government subsidies to stabilize prices, while others emphasize the need for market-based pricing to reflect rising international energy costs, acknowledging that each approach carries trade-offs. Subsidies can buffer consumers from sudden shocks but strain government budgets and foreign reserves, whereas passing increased costs to consumers can contribute to inflation and higher transport expenses.

Bangladesh’s latest diesel price adjustment follows a policy trajectory distinct from other countries. For instance, India recently reduced excise duty amid rising international fuel prices, whereas Bangladesh raised diesel prices to Tk 135 per litre just five months after a previous increase. Amid these dynamics, the logistics sector faces a critical question: how should a diesel price hike translate into changes in related service charges such as container handling, trucking, and freight rates?

Examining recent adjustments in other transport sectors may provide guidance. Following the September 20 increase, official bus fares rose by about 7 percent per kilometre, and passenger water-transport fares increased by approximately 7.5 percent. Since fuel comprises only a portion of total operating costs—along with labor, equipment, maintenance, electricity, and administrative expenses—tariff adjustments should correspond proportionally to the actual fuel cost share in each service.

For example, if fuel accounts for 30 percent of a service's total cost, a 17.4 percent rise in diesel prices could justify a roughly 5 percent increase in that service’s tariff. If the fuel cost share is higher, the tariff adjustment would be correspondingly greater. This approach contrasts with a practice in which broad percentage increases are applied indiscriminately, which risks amplifying cost burdens through multiple stages of the supply chain—from trucking and container depots to port terminals and lighter vessels.

Data from previous adjustments illustrate some consistency, though the precise methodology remains unclear. A 15 percent diesel price rise in April coincided with an 8.5 percent increase in several ICD charges, while the current 17.4 percent fuel hike has led to a 9.85 percent adjustment in the same categories.

Internationally, mechanisms exist to manage such volatility. In the United States, freight carriers commonly apply fuel surcharges linked to weekly-published diesel price benchmarks. France’s transport regulations mandate adjusting road-freight prices according to propulsion energy costs, with relevant energy surcharges separately itemized on invoices. Similarly, World Bank contracting guidelines provide for price adjustment formulas separating fixed and variable cost elements linked to fuel price fluctuations.

Analysts suggest Bangladesh adopt comparable principles, including a baseline fuel price, service-specific fuel cost shares, transparent benchmarks, scheduled review intervals, and automatic tariff adjustments both upward and downward as fuel prices fluctuate. Such measures would provide predictability and proportionality, mitigating contentious renegotiations and preventing inflationary cascades across the logistics chain.

Long-term port contracts, in particular, could incorporate escalation and de-escalation clauses tied to fuel price variations. Berth operators note that the diesel price has risen from Tk 80 in 2022 to Tk 135 currently, making it difficult for contractors to absorb the full increase indefinitely without contract adjustments.

Ultimately, while external factors such as geopolitical tensions affecting global fuel markets remain outside domestic control, Bangladesh can improve how energy price shocks are transmitted through its logistics system. Establishing a clear, formula-driven approach to tariff adjustments offers a more sustainable and transparent alternative to reactive, across-the-board hikes, supporting both the financial viability of logistics providers and the competitiveness of exporters.
