When will the currency wars end?

Bloomberg reports:

Finance chiefs from South Korea to South Africa signaled they may act to slow gains in their currencies, just four days after the Group of 20 vowed to soothe trade tensions in the $4 trillion-a-day foreign-exchange market.

Asian currencies fell to a one-week low after Bank of Korea Governor Kim Choong Soo said today that measures to mitigate capital flows could be “useful.” Hours later, the rand dropped as South African Finance Minister Pravin Gordhan said his government will use part of higher-than-expected tax revenue to build foreign reserves as it attempts to weaken the currency.

The shifts suggest G-20 members will keep trying to defend their economies from the slide of the dollar and capital inflows even after the group promised Oct. 23 to refrain from “competitive devaluation” and to increasingly embrace market- determined currencies.

This is politics-as-usual.  As the central banks of the world engage in a race to the bottom, you should protect your wealth with investments that are racing the other way.
