epSos .de / Flickr, CC Investors are flooding into precious metals as fears of a global slowdown grip markets and send people toward so-called safe-haven assets.

"The Flow Show," a weekly note from Bank of America Merrill Lynch that tracks the movement of money around global markets, shows that this week investors poured money into the precious-metal markets at some of the highest levels in about six years.

In total, $1.6 billion (£1.1 billion) of money tracked by BAML was spent buying up gold and other precious metals, including silver and platinum. Only one week since 2010, early in 2015, saw higher inflows into precious metals.

Here's the chart:

Gold's reputation as an asset people buy in times of trouble is legendary, with the precious metal almost always seeing big inflows at times of economic and financial crises. Gold's appeal as a physical asset makes it incredibly attractive when markets are volatile and uncertain.

To emphasise the fears wracking the markets, the biggest outflows last week, BAML shows, were from three risky asset areas getting slammed: $6.8 billion (£4.6 billion) flowed away from equities, $2.5 billion (£1.7 billion) moved out of high-yield bonds, and $1.1 billion (£750 million) left emerging-market government debt.

The high levels of cash flowing into the precious-metal markets have sent prices soaring in 2016, and they're now at a one-year peak. Since trading began for the year, gold's spot price has jumped by more than 16%, taking it to its highest level in a year. Silver has also climbed, up 13%, while platinum has gained 7%. Here's how gold looks in 2016:

BAML's flow note comes a day after the Daily Telegraph reported that ETF Securities, an index fund provider, saw £239 million ($347 million) flow into gold on February 9, the highest one-day inflow since the financial crisis.
