Putin's Gold Peg: Will It Hold?

On March 28, the Central Bank of Russia resumed gold purchases from Russian banks at a fixed rate of 5,000 rubles per gram of gold, which is ~155,517 rubles per Troy ounce of gold.

Presently, the market price for gold is 165,093 rubles per troy ounce of gold.

The market price flirted with Putin's gold peg before trending back up through the remainder of the week.

When holders of gold can get a better price in the market than from the BoR, how long can Putin hold the fixed price?
