BHP vs. Rio Tinto (ASX 200): Which Mining Heavyweight Should You Buy as Commodity Prices Rebound?

Copper is once again near its all-time highs. Iron ore prices continue to trade above US$109 per tonne, when expectations were for a decline to around US$80 per tonne. The two largest stocks on the Australian Securities Exchange, BHP Group (ASX:BHP) and Rio Tinto (ASX:RIO), have been leading the way.

As Australian investors see the commodity cycle play out, there comes a point where an investor must ask: which of the two is the better purchase at the moment – BHP or Rio Tinto?

This is not easy to answer. At first glance, both miners seem identical: giant multinational mining companies with diversity, dividends, and a lot to do with China's insatiable industry needs. But a closer examination will reveal their distinct characteristics, and here they are.

The 2026 Setup: Why Both Stocks Are Flying

Before looking at which one is performing better than the other, there is need to know what is causing the rise in both companies. One month's jump in copper price made Rio Tinto hit record high A$252 billion valuations. It rose due to increased bets on inflation pushing commodities up. Copper reached US$6.22 a pound close to its record price after rising by 12% over a rally period of a month because of the belief that the rise in demand would create more value for investors.

BHP was not outdone. The jump in copper price has helped the company increase by 3.8% in a single day for the fourth time in five days. 

The company’s iron ore did not fall short either. It defied all expectations set out by analysts and maintained above US$90 or even US$80 per tonne. It has risen to reach the high of US$111 per tonne and now stands at over US$109 per tonne.

Together with the increasing copper price, two out of the three ASX 200 mining stocks have smashed the benchmark index in 2026.

BHP Share Price ASX: Where Does It Stand?

However, the BHP share price, which ASX investors follow closely, has been a bit challenging in the year 2026. Initially, BHP underperformed Rio Tinto at the beginning of the rally until conviction increased for copper. For Goldman Sachs, BHP still holds a positive view, especially due to the company's exposure to copper, which is characterized by "ongoing supply side challenges and increasing demand." It is expected that BHP's EBITDA from copper will rise by an estimated US$3 billion to US$10 billion, which is 45% of the total EBITDA.

This is why the BHP story in the year 2026 is all about copper. Unlike the past, this is not merely a diversified mining firm that has copper operations. Rather, it's all about the strategic repositioning of the firm such that copper, extracted primarily in South America, becomes the main contributor to the bottom line. Indeed, BHP makes close to 50% of its earnings from copper.

For those interested in copper stocks ASX 2026, BHP is the one and only largest exposure in the whole exchange in terms of market capitalization.

BHP share price forecast next 5 years: While Bank of America maintained its target price of A$69 per share for BHP, there were still concerns expressed. Both BHP and Rio Tinto currently trade close to all-time highs based on their multiples to net present value; therefore, they have little potential to grow multiples should commodity prices remain constant. The analysts pointed out that pressures are increasing from cost-side, potentially squeezing margins in case commodity prices stall or fall. Over five years, the bullish thesis for BHP relies on the copper demand story being fundamental rather than cyclical, powered by data centers, EVs, and global grid infrastructure, whereas the bearish thesis lies in the slowdown of China, reducing iron ore prices prior to copper tonnage offsets.

Rio Tinto Share Price: Record Territory and a Different Story

The Rio Tinto 2026 performance to date has been quite extraordinary. As I write in mid-May 2026, Rio Tinto shares are trading around the level of A$191.57. This represents the highest ever closing price level in the company's ASX listing history. The rally in Rio Tinto share price from its recent cycle low at A$144.41 to its intraday all-time high level of A$192.30 in just ten weeks' time has been justified in terms of valuation.

The Rio Tinto share price in 2026 is now up 36.5%, while over the year to date its price level is higher by an outstanding 65%. 

There is a broad structural basis to invest in Rio Tinto rather than BHP. It is essentially a diversification of commodities that is different between these companies, including aluminium and lithium as well as a somewhat smaller, but still growing, copper portfolio compared to BHP. There is one critical difference for 2026 which makes it fundamentally different from the previous cycles. The breadth of demand catalysts is much higher this time around.

BHP vs. Rio Tinto ASX: The Commodity Mix Comparison

Here is the point where the two companies diverge significantly, and where your expectations for the next five years should be the guiding factor in your analysis.

For BHP, its commodities mix is becoming more focused on copper than ever before, while at the same time iron ore remains a core component of the company, with a future growth project in potash from Jansen, Canada to take shape in the latter half of the decade. Coal holdings have been steadily sold off. It is all about green energy transition metals.

For Rio Tinto, there are four commodities involved in the mix – iron ore (Pilbara, the most profitable system of iron ore mines in the world), copper (now in full swing at Oyu Tolgoi, Mongolia), aluminium (a controversial commodity), and lithium via the Rincon project in Argentina. This represents the company’s biggest strength and weakness; it carries multiple commodity bets, but not necessarily a pure play on one commodity, such as copper.

Final take on commodities mix: If your thesis is that copper outperforms all other commodities during the next five years, then BHP wins hands down. Otherwise, the more diversified commodities mix of Rio Tinto makes it a better choice.

Rio Tinto Dividend History vs. BHP Dividends: The Income Case

However, both miners have some of the highest yields in their class within the ASX market, thus explaining why income investors would like to know which one is the more favorable dividend paying company.

2026 BHP dividends: The BHP board declared an interim dividend of 73 US cents per share for the half year ending December 31st, 2025 at a payout ratio of 60%, payable on March 26th, 2026. BHP has distributed more than US$110 billion back to the company’s stakeholders since its capital allocation strategy was launched. BHP dividends are fully franked, giving them added value for the Australian-based taxpayers.

Rio Tinto dividend history: The dividend payout ratio of Rio Tinto stands at US$4.00 per share annually, yielding an annual dividend trailing yield of about 3.65%. The dividends are paid semi-annually. In terms of dividend growth, Rio Tinto has experienced a negative dividend growth ratio of -33.86% in the last year, while its dividend growth in the last five years stands at -18.17%. The reason for negative dividend growth is the cyclical nature of income earned from mining activities – when the price of commodities drops, the dividends follow suit.

Five-year total return comparison: Investors that had purchased A$10,000 worth of Rio Tinto in May 2021 would find that his/her shares have gained A$224.57 worth of accumulated value, a growth rate of 83.9%. His/her shares would now be worth about A$18,389 which include dividends amounting to A$40.09 per share. Investor who had invested A$10,000 in BHP stocks would see that it grew from A$42.52 to A$59.82 over five years at a growth rate of 40.1%. It pays A$14.92 dividends per share in ten distributions fully franked.

In the last five years, Rio Tinto has delivered better performance than BHP in total returns. The fully-franked dividends of BHP offer a strong advantage when investing for income by Australian investors.

The Bear Case: Why Analysts Are Turning Cautious on Both

It would be unfair to make only the bull arguments. Bank of America recently took an important position. According to this financial institution, both Rio Tinto and BHP should be rated as neutral since, according to its analysts, there is no justification for a more positive attitude towards these companies given their current situation and prospects. This position was qualified as "a very much a top-down call rather than a call on stock specifics."

Both of these companies received ratings downgrade due to the deteriorating macro environment, especially concerning China's appetite for raw materials. Moreover, both companies currently are trading close to their all-time highs, which adds some additional risks associated with a further growth potential. Also, analysts point to the increased pressures on costs – the increase in salaries, energy prices, etc.

The key contradiction here is that both stocks look like very attractive investments because the business fundamentals behind the shares look good, the cycle for the commodities looks positive, and you are not buying them cheaply. The issue remains whether the momentum for commodities will support high share values.

here is no universal answer, but here is a framework based on investor type.

 The key here is having maximum exposure to copper from the big caps in the ASX IT index, you want fully franked dividends, and you have no doubts about the demand for copper due to the green energy transition through the end of the decade, despite the course being taken by China right now. With regards to the BHP stock price forecast, it’s directly linked to copper.

Your preference is for greater diversification in commodities, you are happy to have a higher weighting in iron ore (which is still extremely lucrative due to the Pilbara mines), and you are attracted to the better total returns performance over the past five years. It is the growth potential of Rio through its lithium ventures and Oyu Tolgoi copper mining that gives it an edge over BHP.

The Bottom Line for ASX Mining Stocks

The state of commodities going into the latter part of 2026 is as positive as I can remember. "Copper sits at the intersection of everything" and is significantly under-supplied – according to some analysts, it marks the early stages of a commodity super-cycle which is affecting industries, bulk materials, energies, and critical minerals.

BHP and Rio are two of the clear beneficiaries here. They’re not cheap after a significant rerating. But they both generate dividends. Plus, they both have identical macro risks associated with a potential disappointment in China or in commodities.
