The gold price climbed this week, peaking Friday at $1,271.76 per ounce. That’s its highest level since February 2015. 

While that’s great news for gold bugs, what’s perhaps more interesting is that it’s not just this week that’s been positive for the yellow metal. In fact, according to the Financial Times, gold is currently enjoying its best start to the year since 1980. What’s more, it’s risen 21.8 percent since its December low, meaning that it’s in bull market territory for the first time since 2013.

In terms of what’s driving the gold price, one analyst aptly told Kitco that an “explosive cocktail” of factors are pushing the metal up. However, at the moment, it seems like investor buying is its main driver — data from Bank of America Merrill Lynch shows that gold funds are seeing their biggest inflows in seven years, with $7.9 billion entering such funds in the last four weeks.

Encouragingly, many market watchers think that gold’s momentum will continue. Notably, Kitco quotes Bart Melek, head of commodity strategy at TD Securities, as saying that gold looks set to hit his firm’s Q1 price target of $1,300. “There are many reasons to think that gold will rally to $1,300,” he said.

For its part, the silver price also climbed this week, and peaked Friday at 11:00 a.m. EST at $15.74 per ounce.

On the base metals side, Reuters states that benchmark LME copper rose 3.5 percent on Friday to close at $5,027 per tonne. Prior to that it hit $5,059, its highest level since last November. Overall, benchmark LME copper has made a weekly gain of 7 percent, its largest since December 2011.

Explaining copper’s positive performance, one trader told Reuters that a lower US dollar (caused by strong US jobs data released Friday) prompted “a scramble by funds to buy copper and triggered pre-set buy orders after copper broke through key levels.” He added, “
