So why does this happen? In Risk-off markets why do JPY and CHF rally?

Be it goods or services, both the net exporters trail blaze leaving little room for imports impact resulting in decades of net current account surpluses. As a result Japan and Switzerland have positioned themselves as a net creditor of the global economy.

Another reason is both the countries have maintained low interest rates spurring the economy with consumer spending. Investors tend to borrow both these currencies at lower to zero interest rates and invest in high yielding assets from other countries.

In times of panic, the investors unwind the trades and sell off high yielding risky currencies and go back to parking their funds in JPY and CHF.
