Gold is all that nationalist leaders in Europe’s east can talk about these days.

Just this week, Poland’s government touted its economic might after completing the repatriation of 100 tons of the metal. Over in Hungary, anti-immigrant Prime Minister Viktor Orban has been ramping up holdings of the safe-haven asset to boost the security of his reserves.

The gold rush mirrors steps by Russia and China to diversify reserves exceeding $3 trillion away from the dollar amid flaring geopolitical tensions with the U.S. Motivations in Europe’s ex-communist wing, however, can vary.

Take the latest example. Former Slovak Premier Robert Fico, who has a shot at returning to power, urges parliament to compel the central bank into bringing home gold stocks stored in the U.K.

The reason? Sometimes your international partners can betray you, Fico said, citing a 1938 pact by France, Britain, Italy and Germany allowing Adolf Hitler to annex a chunk what was then Czechoslovakia, and -- more recently -- the Bank of England’s refusal to return Venezuela’s gold stock over political differences.

“You can hardly trust even the closest allies after the Munich Agreement,” Fico told reporters. “I guarantee that if something happens, we won’t see a single gram of this gold. Let’s do it as quickly as possible.”

His comments came despite the U.K. being one of Slovakia’s closest allies after the Soviet empire crumbled, helping ease the path to European Union and NATO. Fico said Brexit and the risk of a global economic crisis put Slovak gold stored in Britain in a dangerous situation.

Polish Power

The gold Poland brought back also came from the U.K., though there was no questioning of Britain’s reliability by central bank Governor Adam Glapinski.

Instead, he said he wanted to demonstrate the strength of his nation’s $586 billion economy -- the largest in the EU’s east. Poland has doubled its gold holdings in the past two years and now has the region’s biggest stockpile.

Hungary, though, has been an active buyer too. Gold reserves surged 10-fold last year, setting the clamor for the metal in the countries around it in motion.

Serbia’s strongman leader Aleksandar Vucic took note, ordering the central bank to boost reserves and prompting the purchase of nine tons in October. Vucic said last week that more should be bought because “we see in which direction the crisis in the world is moving.”

The biggest nation to emerge from the breakup of Yugoslavia still keeps some of its gold abroad, the central bank said by email. The region is buying more of the metal because of global uncertainty over trade and politics, Brexit and low interest rates, it said.

Romania had also sought to relocate some of its gold reserves from the U.K., but those plans were put on hold when the government behind them was ousted in October.

For the no-nonsense leaders that have come to dominate eastern Europe, the main benefit may be the message to voters that hefty holdings of the precious metal conveys.

“Gold is a symbol,” said Vuk Vukovic, a political economist in Zagreb. “When states purchase it, people everywhere see it as a sign of economic sovereignty.”
