"People are doing fear trade now and running towards gold," said Michael Matousek, head trader at US Global Investors, adding, investors were becoming very unsure of what US President Donald Trump was planning to do.
"That tells you need to have higher allocation to gold in your portfolios."
Trump on Thursday said that Washington will impose a 5pc tariff on all goods coming from Mexico, starting on June 10, until the flow of illegal immigrants into the United States ceases.
Meanwhile, Mexico's President Andres Manuel Lopez Obrador, said he would respond with "great prudence" to the threats and called on Mexicans to unite to deal with the challenge.
US stocks opened sharply lower, hit by fears that Trump's threat of tariffs on Mexico could prove the trigger that pushes the world's largest economy into recession.
"The dollar index is still in the 98-area, which is normally a headwind for gold but because of the extreme stock tumbling, it seems to be ignoring the normal headwind," said George Gero, managing director at RBC Wealth Management.
"Gold is probably going to stay in this $1,300 area as long as the selloff (in equities) continues."
The dollar briefly trimmed its losses versus a basket of currencies on Friday as stronger-than-forecast data on US consumer spending and income in April tempered some worries about a slowing US economy.
Meanwhile, expectations of a cut in interest rates by the US Federal Reserve increased after recent weak economic readings from the United States added to concerns raised by the prolonged US-China trade dispute.
US interest rate futures rose on Friday as traders increased their bets on more than one rate cut from the Fed.
Lower interest rates would support gold because they reduce the opportunity cost of holding non-yielding bullion.
