We use up to 24 years of weekly data on 11 bilateral yen exchange rates to examine the evidence of an emerging yen bloc in Australasia, North and Southeast Asia. The logarithmic first differences of these exchange rates are modelled in response to variations in their US dollar, German marc, and UK pound counterparts using a general-to-specific dynamic Newey-West estimation strategy. We find strong evidence contrary to the notion of a de facto yen bloc. Each 1 percent rise in the US dollar (German marc, UK pound) effective exchange rate causes a mean 1.27 (1.8, 0.18) percent appreciation in the regional currencies vis-à-vis the yen. Moreover we find convincing evidence inconsistent with the postulate of an emerging yen bloc in these multipliers over time.
