Gold’s biggest rally since the 1970s is being stoked by “gold-plated Fomo”, as investors fearful of missing out on returns and worried about inflation add the precious metal to their portfolios.

The bullion price has rocketed nearly 50 per cent this year to a record high above $3,800 per troy ounce after US President Donald Trump’s trade war sparked a rush to haven assets and sent the dollar tumbling.

But even when tariff-induced volatility in financial markets receded over the summer, the gold price accelerated, with a near-12 per cent jump in September alone marking the biggest monthly gain since 2011.
