Russia has effectively commoditised its currency, particularly for energy, gold, and food. It is following China down a similar path. In doing so it has undermined the dollar’s hegemony, perhaps fatally. As the driving force behind currency values, commodities will be the collateral replacing financial assets. It is interesting to observe the strength in the Mexican peso against the dollar (up 9.7% since November 2021) and the Brazilian real (up 21% over a year) And even the South African rand has risen by 11% in the last five months. That these flaky currencies are rising tells us that resource backing for currencies has its attractions beyond the rouble and renminbi.
