By using a projected 20% devaluation of the yen, and given unit sales figures and industry elasticity, the competitive exposure of GM to the real JPY-USD spot exchange rate is roughly $1.6b. This base case is established as the most likely scenario, yet sensitivity analysis of varying percentages of JPY content per-vehicle and cost-savings distribution to consumers showcase a much wider range of potential exposure values. When summing this competitive exposure with the remaining exposures (commercial, affiliate, and borrowing), I find that GM has an overall $1.2b exposure to the yen globally. Further, I suggest an alternate, less information-intensive means for calculating a similar figure, which includes regression of GM returns to market returns, then finding an exposure coefficient to JPY-USD fluctuations; this helps to show how returns of the firm are correlated specifically to their yen exposure. While direct calculations are not performed, this method…
