Gold is still difficult to sell with sanctions.

> Russia could pledge that gold or sell it. But to whom? Most potential customers for Russian gold can be threatened with sanctions. Those who might defy the threat couldn’t afford to take very much: The entire GDP of Venezuela, for example, is only about $480 billion.

> Would China be content merely to take legal ownership of the gold and leave the metal inside in a Russian vault? Doubtful. One ton of gold is worth about $61 million, so $139 billion would weigh about 2,290 metric tons. It’s certainly conceivable for a locomotive to pull a train of that weight from Moscow to Beijing. But it would constitute a considerable logistical and security undertaking to load, move, unload, and secure the gold for a train trip across Siberia.
