Sammendrag
This thesis investigates whether information derived from AIS-data incorporates superior information

about future freight rates. Specifically, we assess if such data improve the ability to predict

TD3 spot rates between August 2015 and mid-February 2016. The ability to anticipate short-term

fluctuations in freight rates is a key component to long-term profitability for both shipowners and

charterers, making the purpose of this thesis an important objective.

The AIS-data contain information about 81,728 individual shipments of crude oil between 2013

and mid-February 2016, and are reduced to 53,116 observations after proper cleansing. For analysis

purposes, information deemed relevant are converted into weekly time series, ending up with

162 observations in total. Data-driven selection tools are then used to identify the most powerful

predictors of future TD3 rates, and a multivariate VAR is specified in line with these results. In order

to investigate the relative performance of information derived from AIS-data, a one-step-ahead

forecast is conducted, and evaluated against an univariate ARMA and a multivariate VAR solely

based on publicly available data.

Our results suggest that multivariate models perform relatively better than univariate models to predict

future freight rates. Further, comparing error measures from the two multivariate VAR models

specified, we find weak evidence in favour of using information from AIS-derived data for predictive

purposes.
