Marine commerce is a pivotal segment of blue economy comprising of business services, marine retail services, marine financial services, maritime insurance, ship leasing, support activities, wholesale trade, maritime legal service and other marine services. Maritime insurance businesses have registered growth over time. Unlike general insurance, maritime insurance involves certain unique challenges in terms of risk perceptions. The sector globally faces challenges due to fraudulent marine shippers and quality of merchandise. Ship finance is another potential sector for expansion in the Indian Ocean region. Marine conservation finance is emerging as a separate category of marine financial services. Conservation of marine resources may not be preferred by the bankers and financial markets as those do not match the revenue streams and assured profits of the typical financing instruments. This segment faces serious funding gap which needs to be met by special financing mechanisms. Expansion of scope of marine conservation and collaboration between specialist financiers should be encouraged to tap this emerging field of financing of blue economy.
