These events may have initiated an alliance between the Greeks and the Yuezhi (even possibly a dynastic alliance), explaining why the Yuezhi gained pre-eminence after the reign of Hermaeus, why their rulers such as Heraios then minted coins in a way very faithful to the Greek type, and why the first Kushan emperor Kujula Kadphises associated himself with Hermaeus on his coins, in a way characteristic of a ruler asserting his pedigree.
