The yen is often seen as a global barometer of risk aversion. The graph below demonstrates the strong inverse relationship between the movements of the yen (against the euro, in this case) and those of the Dow Jones World Index. As shown, a falling yen indicates risk tolerance (and a willingness to buy risky assets) and a rising yen shows risk aversion (and an indisposition towards risky assets). A downturn in the yen exchange rate could be a good indicator to keep an eye out for confirmation of better times ahead for stocks and commodities.
