Risk-off

In a risk-on environment, they then sell those currencies and use the proceeds to buy risk assets with greater price appreciation potential. In a risk-off environment, they're compelled to sell their risk assets and buy back those funding currencies that they previously sold.

The yen tends to appreciate in the aftermath – first two quarters – of risk-off episodes, whether the appreciation is measured as nominal, real effective, or bilateral against the U.S. dollar (Figure 6).
