ABSTRACT
We analysed interest rate forecasts from Australia, China, Hong Kong, India, Indonesia, Malaysia, New Zealand, Singapore, South Korea, Taiwan and Thailand. We assessed 532 forecast time series with a total of 85,264 individual interest rate forecasts. To do so, we carried out a comparison to naïve forecasts and investigated the forecast time series for topically orientated trend adjustments. In addition, we deployed the sign accuracy test and the unbiasedness test. The results are very sobering in part: 95.9% of all forecast time series are characterized by the phenomenon of topically orientated trend adjustments, and 99.4% of all forecast time series proved to be biased. Only a small proportion of the forecast time series (3.6%) reflected the future interest rate trend significantly more precisely than a naïve forecast. However, at the same time some of the results of the study are surprisingly positive. The sign accuracy test revealed that 48.3% of all forecast time series predict the interest rate trend significantly better than a random walk forecast.

11 In the forecasts of the prime lending rate in Hong Kong, it can be seen that 26 out of 30 forecast time series (86.7%) were superior to the naïve forecast. In the case of the forecasts of the 3-month rate in Hong Kong, 24 out of 38 forecast time series (63.2%) were superior to a naïve forecast, while in the forecasts of the 3-month rate in India, at least the forecasts with a 13-month forecast horizon were highly successful: 9 out of 12 forecast time series (75%) were more precise than the corresponding naïve forecast. Among the forecasts of 10-year interest rates in Indonesia, the forecasts with a horizon of 13 months were once again very successful. About 9 out of 12 forecast time series (75%) are more exact than a naïve forecast. Forecasts of the base lending rate in Malaysia were more successful than a naïve forecast in 18 out of 30 cases (60%), which is also the case for forecasts of three-month interest rates in Malaysia in 19 out of 36 cases (52.8%). The forecasts of the three-month rate in New Zealand were more precise than a naïve forecast in 25 out of 36 cases (69.4%). Among the forecasts of the 3-month rate in Thailand with a forecast horizon of 13 months, 9 out of 13 forecast time series (69.2%) were superior to the naïve forecast.
