The BHP Group Ltd (ASX: BHP) share price hit an all-time high on Friday, reaching $54.55 in intraday trade.
Unfortunately, its gains didn't hold. The ASX 200 iron ore producer's shares ended the week trading for $53.49. That means the BHP share price is currently 21.2% higher than it was 6 months ago.
But is now a good time to buy BHP?
Let's take a look at what's been driving the ASX 200 giant's share price lately and whether it looks like it will keep climbing.
What's driving the BHP share price?
As The Motley Fool Australia reported on Friday, it seems the BHP share price is being driven higher by factors outside the company's control, namely the price of iron ore and the Australian dollar.
Right now, iron ore is coming off its own all-time high. A tonne of iron ore is currently going for US$193.70 a tonne. That's not quite the all-time high of US$238 per tonne that it hit in early May, but it's still above what it has been in recent years.
At the same time, the Australian dollar is at a particularly low point. Right now, AU$1.00 is worth US$0.74. When the Australian dollar is down, Aussie companies trading internationally get more Aussie dollars in their pockets.
So, we now have a fair idea of some of the major factors driving the BHP share price. But the question is, will they stick around?
Iron ore price
In the case of iron ore, the answer is no, according to the Australian Office of the Chief Economist (OCE).
The OCE expects the amount of iron ore that Australia is exporting to increase by 2022/23 as new mines are put into production. At the same time, it forecasts the price of iron ore to ease.
The OCE's guidance for the iron ore price is about $150 per tonne on average for the remainder of 2021. It expects the price to fall below $100 per tonne by the end of 2022.
Australian dollar
Whether the Aussie dollar's value against the US dollar will go up or down is hard to predict, but some experts forecast it will go up.
National Australia Bank Ltd. (ASX:NAB) expects the Australian dollar will be worth US$0.78 by December 2021 and US$0.80 by March 2022. It predicts it will stay at US$0.80 until 2023, then fall again.
Is now a good time to buy BHP shares?
Unfortunately, using just these metrics, it doesn't look like a great time to buy the ASX 200 giant.
However, it's impossible to predict whether the BHP share price will go up or down.
Time will tell how the market treats BHP in the near future, with the most telling answer to come later this month when BHP releases its full-year results on 17 August.
