Forward Rate Unbiased Hypothesis depicts that under rationalized expectation conditions and the neutrality of risk, the forward rate of exchange is a predictor of unbiased nature towards future spot rate of exchange. A major literature with empirical evidence has indulged in testing the foreign exchange market unbiasedness hypothesis through use of forward rates of exchange (Domowitz & Hakkio, 1985). The hypothesis has a relationship to the FX efficiency of market notion as given through the condition of UIP (uncovered interest parity rate). This UIP illustrates that the expected change in rates of exchange needs to be equivalent to the present differential of rate of interest or within the arbitrage absence, it needs to be equivalent to forward premium (Chiang, 1988). Within the arbitrage absence and under the UIP, the rate of forward exchange provides a future change based unbiased forecast in the rate of spot exchange.

This is the essential unbiased hypothesis assertion. However, according to Mariana et al., 1993), the JLR test has been used for testing this hypothesis. A panelled test for unit root was utilized for enhancing the testing power as it helps in exploiting the essential dependencies of cross section found between the series of panel. Such a test offered essential benefits of methodologies over substitute standardized test with panel unit-roots. When applying to a forecast error panel series for 8 main currencies on the era of post-Bretton Woods, overwhelmingly the evidence supported a slope of unit coefficient value (Bakshi et al., 1997). This occurs within the regression co-integration between future spot rates of forward and corresponding nature. Such a finding of strong and robust nature however is in contrast with the current literature mixed evidence. In any case, the FRUH has been rejected for every currency except the mark of Swiss Franc, Lira and Deutsche because of the failure of condition of orthogonality.
