In the case of Suezmax tankers (Table H-3), the same seasonal pattern is present, although somewhat moderated in that the maximum spread of indices is lower. Similar trends are observed for Aframax tankers (Table H-4). For both Suezmax and Aframax tankers, data for the period since 1990 are insufficient to permit conclusions to be drawn.
Data for product tankers trading from the Caribbean to the east coast of the United States are given in Table H-5. Despite the fact that such tankers are smaller and operate in totally different trades from the VLCCs, Suezmax tankers, and Aframax tankers discussed earlier, the impact of the seasonal pattern on freight rates is very strong.
