If the price of oil hits $150 a barrel, it will trigger a global recession, the boss of US financial giant BlackRock has told the BBC.

Larry Fink, who leads the world's largest asset manager, said if Iran 'remains a threat' and oil prices stay high it will have 'profound implications' for the world economy.

In a wide-ranging exclusive interview, he also denied there was an AI bubble, although he said the new technology meant too many people were pursuing university degrees and not enough doing technical training.

BlackRock is a financial colossus, controlling assets worth $14 trillion (£10.5tn), and is one of the biggest investors in many of the world's largest companies. Its size and spread give Fink a unique insight into the health of the global economy.

The conflict in the Middle East has triggered wild moves on financial markets as people try to assess what will happen to energy costs. For Fink, it is too early to determine the ultimate scale and outcome of the conflict, but he believes it will be one of two extreme scenarios.

In one, if the conflict is settled and Iran becomes a country that can be accepted again by the international community, then the price of oil could fall back to below where it stood before the war. But if not, he warns there could be years of above $100, closer to $150 oil, which would lead to 'a probably stark and steep recession'.

The surge in energy costs has led some in the UK to argue for greater domestic production of oil and gas. Fink stresses the need for countries to be pragmatic about their energy mix and highlights that providing cheap energy is essential for economic growth and raising living standards.

He also comments on how the rising energy prices represent a regressive tax that disproportionately affects poorer populations. While the UK already has some solar and wind power, he believes if oil prices were to rise sharply, there would be a significant shift towards solar and wind energy sources.

Fink also addressed concerns regarding the surge in AI investment, rejecting the notion of an AI bubble and emphasizing the necessity for the United States to enhance its AI capabilities to compete globally, particularly against China.

In closing, Fink reflected on the changing job landscape due to AI and the need to value practical skill sets such as plumbing, welding, and electrical work, advocating for a balanced approach to education and career paths in lieu of traditional university degrees.
