Donald Trump and Mohammed bin Salman each have contradictory objectives in 2025. The US president-elect wants to apply "maximum pressure" on Iran, but won't want the spike in oil prices that may accompany it. The Saudi crown prince is sick of forgoing oil revenue by pumping 3 million barrels below his 12 million barrel daily capacity – but will be wary of a price crash if he opens the taps. Even so, there's a way for their bromance to bloom.

On the face of it, there's much for MBS and Trump to disagree about. If the new president delivers on pledges to slash permitting times and enable fossil fuel companies to "drill, baby, drill", then oil prices could pitch even further below the $100 a barrel level at which the Saudi budget balances. Unlike Trump's first term, MBS has been getting closer to Iran via talks brokered by another Trump foe – China. And Saudi's predominantly youthful 33 million population is naturally sympathetic towards Palestinians – which might jar if Trump brokers a ceasefire deal that seems overly generous to Israel.

Still, MBS-Trump relations are likely to be significantly warmer than the crown prince's frosty relations with President Joe Biden. Trump and adviser Elon Musk were seen recently at an Ultimate Fighting Championship bout with Yasir Al-Rumayyan, boss of Saudi's $925 billion Public Investment Fund. And oil dynamics may help rather than hinder.

At 13 million barrels, US daily oil production is the highest in the world. But according to Goldman Sachs, the crude price required in the key Permian region to drill new wells and manage a 15 percent return is the $70 a barrel at which it traded in late November. Most US oil production is on private land rather than the public areas Trump controls. With forecasters like the International Energy Agency anticipating a price-sapping supply glut of 1 million barrels a day in 2025, and the Organization of the Petroleum Exporting Countries and affiliates like Russia keen to unwind production cuts, it's possible the US oil flood is more like a trickle.

As such, MBS and Trump's interests may align. Imagine the US tries to shrink,  the $53 billion of annual oil revenues Iran made in 2023 via tougher sanctions. If effective, that could see 1.7 million barrels of Iranian oil exports a day disappear from the market, which could send prices spiking even if the IEA's anticipated surplus materialises. Hence Saudi could then deploy its surplus with impunity. While oil prices would fall, the kingdom's market share could soar.

Such a scenario would allow both MBS and Trump to win in 2025. But both could grease the wheels. Saudi could invest in US sports bets like tennis via the PIF's SURJ Sports Investment company. Trump could champion major chunks of foreign direct investment by US capital providers in the kingdom to juice its Vision 2030 diversification agenda, particularly in the field of artificial intelligence. If so, Saudi might end the year more firmly in the US camp.
