Segment 1: Nigeria’s Refinery Revolution (00:11–09:11)

Main Theme

Ali Kodangote’s $20 Billion Oil Refinery
Nigeria, Africa's largest oil producer, has long struggled with shortages and import dependency for refined fuels. But entrepreneur Ali Kodangote's massive new refinery is reshaping the landscape, promising both opportunities and controversy.

Key Discussion Points

• Kodangote’s Background and Ambitions

  • 68-year-old entrepreneur; runs a conglomerate covering cement, agriculture, mining, and now oil refining.
  • Opened $20 billion refinery in 2024 near Lagos; covers half the size of Manhattan.
  • Processes 650,000 barrels/day, supplying gas, jet fuel, fertilizer (02:42–03:21).
  • Expansion aims: to serve Nigeria, neighboring African countries, and global markets.

• Geopolitical Context

  • Recent global events (e.g., Strait of Hormuz blockage) are making Nigerian energy both more valuable and geopolitically significant.
  • Kodangote receives international attention and business inquiries as other sources of refined products are disrupted.

    “It’s not even about price, it’s about availability, which we have now actually delivered.”
    – Ali Kodangote (02:08)

• Economic and Social Benefits

  • Nigeria historically spent scarce dollars re-importing its own crude as refined products.
  • The new refinery cuts out this dependency, saving currency and eliminating decades-long fuel shortages.
  • Kodangote’s plans could boost energy security across West Africa (03:51–04:57).

• Criticism and Concerns: Monopoly & Local Impact

  • Kodangote accused of monopolistic practices; leverages political influence, tax breaks, and government import bans.
  • Nigeria’s regulators are freezing fuel import licenses—effectively placing national energy in Kodangote’s hands.
  • Critics highlight potential downsides: lack of competition, risks of single-point dependency.

    “You’re basically trusting the country’s entire energy security into one man’s hands.”
    – Ore Ogambi (05:19)

• Employment and Knowledge Transfer

  • Fewer jobs than expected; high-skilled technical roles often filled by foreign subcontractors (esp. Indian experts).
  • Limited local skills transfer and inspiration for future industrialists. Kodangote prioritizes efficiency over maximizing Nigerian employment.

    “He says it doesn’t matter whether they are English, they are Indians, they are Nigerians, it doesn’t matter. But they are our staff.”
    – Ali Kodangote (07:00)

• Kodangote’s Vision and Confidence

  • Aspires to near-Saudi refining capacity (almost 48% of Saudi Arabia’s output).
  • Sees rival African industrialists as unlikely:

    “There’s nobody. I’m telling you, as a proud African, there’s no African that can build a refinery.”
    – Ali Kodangote (07:14)

• Global Reach and Next Steps

  • Sales are not limited to Africa: exports to Brazil, Europe, America; fertilizer business booming amidst global shortages.
  • Plans for public listings in both Lagos and London.
  • Increased resilience for Nigeria and Africa amid global shocks; future expansions into steel, mining, copper smelting.

    “When you come back in three years time…what you have seen today in the complex, it will be three times [as big].”
    – Ali Kodangote (08:56)

Notable Quotes & Moments

• “Nigeria would have been at a standstill without the refinery.”
  – Ali Kodangote (03:21)
• “Africa is much better off because they have Africans like this investing a lot of their capital into the continent.”
  – Ore Ogambi (08:16)
• “He left us with a promise: When you come back in three years time, what you have seen today… it will be three times.”

Segment 2: Tehrangeles – Iran’s Diaspora in California (09:36–15:20)

Main Theme

Iranian Diaspora Reactions to U.S.-Iranian Conflict
In Los Angeles’s “Tehrangeles,” Iranian-Americans are divided on how the U.S. should intervene in Iran following recent bombings and the potential fall of the regime.

Key Discussion Points

• Demographics: Half of Iranian-Americans live in California; around 230,000 in greater Los Angeles (09:36–09:47).
• Community Diversity: Multi-generational, multi-ethnic; significant populations of Iranian Jews.
• Reactions to Conflict:
  • Celebrations after the death of Khamenei; restaurants serving champagne.
  • Deep disagreements about continued U.S. military involvement versus allowing Iranians to determine their own future:
    • Elham Yaguvian: Favors stronger U.S. action to cripple the regime (12:45).
    • Ruzbe Farhanipur: Skeptical, fears another “forever war”; urges U.S. to declare victory and depart (13:24).
  • Both agree: leadership for Iran should be chosen by Iranians, not by foreign powers.

    “Honestly, I believe that choosing the leadership for Iran, it should be in control of the Iranian people. Not west, not Israel, no, no one else.”
    – Elham Yaguvian (14:12)

Notable Quotes

• “That’s a big victory. Cheers and leave.”
  – Ruzbe Farhanipur (13:53)
• “It should be in control of the Iranian people. Not west, not Israel, no, no one else.”

Segment 3: Cancer, Crime, and the Surprising Link (15:20–20:23)

Main Theme

A New Study Connects Cancer Diagnosis to Higher Crime Rates
Inspired by the plot of "Breaking Bad," researchers in Denmark explore whether a cancer diagnosis increases the risk of criminal behavior.

Key Discussion Points

• The Study:

  • Denmark/Netherlands administrative data, 1980–2018.
  • Cancer diagnosis leads to a 14% increase in the likelihood of committing crime relative to non-diagnosed peers.
  • The spike is strongest several years after diagnosis (not immediately), persists for a decade.
  • Economic crimes (theft, drug dealing) and violent crimes surge; homicide and assault specifically rise 21%.

    “They found that things like homicide and assault rose by 21% after a diagnosis.”
    – Ainslie Johnstone (17:45)

• Contributing Factors:

  • Financial hardship, lower employment and income after diagnosis, particularly in areas with weaker welfare safety nets.
  • Men are more likely to offend after diagnosis.
  • Severity of cancer prognosis increases the effect:

    “Patients who were diagnosed with more severe forms…offending rose the most sharply.”
    – Unknown Male Interviewer (18:53)

• Policy Implications:

  • Even in Denmark (strong social welfare), effect is pronounced; could be greater elsewhere.
  • Suggests need for policy awareness of indirect consequences of serious illness.

Notable Quotes

• “I think the effect on crime is just not something that governments think about when they’re designing healthcare and welfare policies. And maybe they should.”
  – Ainslie Johnstone (19:49)

Transcript

[Jason Palmer]

The economist. Hello and welcome to the Intelligence from the Economist. I'm Jason Palmer.

[Rosie Blore]

And I'm Rosie Blore. Every weekday we provide a fresh perspective on the events shaping your world.

[Jason Palmer]

A surprising fraction of Iran's diaspora lives in California. Like Iran itself, it's multi ethnic, multi religious and multi generational. We get a view from what's called Tehrangelis.

[Rosie Blore]

And millions of people are diagnosed with cancer each year. And it's hard to predict how you'll respond until it happens. But a new study finds something I'd never expected. A surprising link between cancer and crime rates.

[Jason Palmer]

First up though,

[Ali Kodangote]

Let me turn off my ring. Hi.

[Unknown Male Interviewer]

Good afternoon, sir.

[Ali Kodangote]

Good afternoon. How are you?

[Ore Ogambi]

All right, sir, just to test your sound, please may you introduce yourself.

[Ali Kodangote]

Ali Ko Dangote.

[Ore Ogambi]

With oil prices skyrocketing, last week was the perfect time for us to visit. Ali Kodangute.

[Jason Palmer]

Ore Ogambi is an Africa correspondent for the Economist.

[Ore Ogambi]

He's not only Africa's richest man, but he's also the owner of Africa's largest refinery.

[Ali Kodangote]

Well, you know, it's a very rough period, you know, especially now. I've seen it two days ago, I think on Tuesday also where the crude ranges between $90 to $119.50.

[Ore Ogambi]

My colleague and I sat down with him on Thursday while news reports from Iran were beaming on the news channel behind us.

[Ali Kodangote]

You know, Nigeria is very lucky to have the refinery because right now it's not even about price, it's about availability, which we have now actually delivered that availability.

[Ore Ogambi]

The Strait of Hummus is still effectively blocked and that means there are lots of people calling up Mr. Dangote's phone for solutions.

[Ali Kodangote]

It's a crazy situation right now, really, and I think this situation will continue for a while

[Jason Palmer]

now. Ori, we spoke about the refinery when it was just opening up. But remind me about Mr. Dangote and how he got where he is.

[Ore Ogambi]

Ali Kudangote is a 68 year old entrepreneur and he runs a conglomerate that does everything from cement to tomato processing. Bit of infrastructure, he's branching out into mining. But in 2024 he opened a massive $20 billion oil refinery. It's just outside of Lagos. It's spread across land about half the size of Manhattan. It is really huge, but that's what's made him extra relevant right now. Since February of this year, that refinery has been able to process 650,000 barrels of crude a day. It turns it into everything from gasoline for cars to jet fuel. And those are things that are in high demand.

[Ali Kodangote]

At the moment, I can tell you, without the refineries would have been out of all the petroleum products. Nigeria would have been at a standstill without the refinery.

[Ore Ogambi]

He has a grand plan to ramp up Africa's industrial capacity and importantly make the region much more self reliant in a world that is this unpredictable.

[Jason Palmer]

So the refinery part of his plan does seem to be working out, not least because of geopolitics as they are.

[Ore Ogambi]

Well, exactly, and before we get into the geopolitics, it's also had real benefits for Nigeria. So despite being Africa's largest crude producer, Nigeria has historically spent lots of scarce dollars re importing its own crude that's being refined abroad. It doesn't have to do that anymore. It gets to save those costly dollars and put them towards much more important things. But also it takes away those fuel shortages that used to create lengthy queues around the corner and that have been a real problem for Nigeria for about 50 odd years. As if Mr. Dangote's refinery isn't big enough, he's planning on expanding it so he can offer that same energy security to countries like Cameroon and Angola, other countries in the region that also are still too dependent on the rest of for their own energy supplies.

[Ali Kodangote]

We will end up being the largest refinery in the world. We'll have almost about 48% of the entire Saudi Arabia's refining capacity. So it's not a small and it will mean quite a lot to the region.

[Ore Ogambi]

Beyond just oil, the refinery also produces fertiliser. And since that's another thing that's getting stuck in the Strait of Hormuz, this is also bringing him new customers. This is good for his margins. It's good for farm yields both in Africa and in the rest of the world.

[Jason Palmer]

So it seems clear then that this refinery has just made a big African businessman even bigger.

[Ore Ogambi]

Well, exactly, Jason. He is a capitalist after all. I mean, if you look at his big cement division, for example, he leveraged tax breaks, political favors, import bans, and he managed to build a company that has such big profit margins, that has such capacity that you wouldn't even bother competing with him. He can single handedly crash prices if he tried. And that's why people accuse him of being a monopolist. That's a common criticism that he receives, although he denies this. He says that he's being completely misunderstood. But you can already see signs of that model being replicated in his refinery business. I mean, for example, Nigeria's regulators are saying that they are freezing new import licenses for anyone else who imports petrol. So you're basically trusting the country's entire energy security into one man's hands. It's great for him and his bank balance. But obviously a less competitive energy environment probably isn't very good for Nigerians.

[Jason Palmer]

But he is giving them a bunch of jobs at what is, as you say, an enormous refinery.

[Ore Ogambi]

I mean, we didn't see as many people on our refinery tour as I think we thought we would. Another way in which Mr. Dangote widens his margins is by relying quite heavily on foreign subcontractors, especially for the more technical kind of high skilled jobs. And that comes at a cost because the kind of local knowledge transfer that you'd hope would really lift up the population and inspire a new generation of Dangotes just isn't really happening. The refinery's managers are mostly Indian experts and there are a few scores of Nigerian employees and trainees that we ran into. But Mr. Dangote's projects are lean on staff by design. He's going for efficiency and high standards.

[Ali Kodangote]

He says it doesn't matter whether they are English, they are Indians, they are Nigerians, it doesn't matter. But they are our staff.

[Ore Ogambi]

And to be honest, I think he is well aware of the new position that this refinery puts him in.

[Ali Kodangote]

We don't have any reason today to go and increase iron capacity because we want to ward off competition. Already where we have competition will never. There's nobody. I'm telling you as a proud African, there's no African that can build a refinery.

[Ore Ogambi]

It's a compliment, it's a point of pride, but it's also a dare to anyone else who wants to try. That is a man that is fully aware of his power.

[Jason Palmer]

But what about that wider picture that you talked about earlier? The ramping up Africa's industrial capacity, helping it become more self reliant. Is that a realistic vision or just. It sounds good?

[Ore Ogambi]

I think it's a bit of both. I think he does care about Africa, but ultimately he's got his eyes set on the whole world. His main buyer of his urea fertilizer is Brazil. He parks his wealth in Dubai. He exports those refined petrol products not just to neighboring countries. And he's not just supplying Nigeria, they're also going to Europe and America. He plans to take the refinery public this year and there are whispers of a dual listing in both Lagos and in London. But I think for all his flaws, Africa is much better off because they have Africans like this investing a lot of their capital into the continent. The region is Becoming more resilient in the face of global shocks. Big oil prices that would usually rattle the continent still are, but slightly less so. And Mr. Rangote has even more lined up. He's branching into steel, into mining. He told us stuff about copper smelting, power generation. That should make the continent even more resilient than it's already becoming. As he gets up to leave his interview and staff popped up from everywhere. He left us with a promise.

[Ali Kodangote]

When you come back in three years time, what you have seen today in the complex, it will be three times

[Ore Ogambi]

and I don't know, Jason, I personally wouldn't bet against him.

[Jason Palmer]

Alright, thanks very much for joining us, Jason.

[Ore Ogambi]

Thanks so much for having me.

[Aaron Braun]

Half of all Iranian Americans live in California and nearly a third of them, which is about 230,000 people, live around Los Angeles.

[Rosie Blore]

Aaron Braun is our west coast correspondent.

[Aaron Braun]

Many of these people arrived after the revolution in 1979 and a lot of them were Iranian Jews. These first immigres were often really wealthy and highly educated and they settled in neighborhoods like Westwood and Beverly Hills. And little by little the community built what's known locally as Tarongeles. Westwood Boulevard is filled with Persian restaurants and bookstores and Iranian flags hang from supermarkets and are across entire buildings like a rug shop that I visited. So when America began bombing Iran last month, many of the residents of Tarangilis came to Westwood Boulevard to voice their support and their hope for the future. This morning I am walking down Westwood Boulevard just south of Wilshire in West la, and I've just been talking to shop owners, restaurant owners about their views of the war. It's about a week now since the bomb. One of the people I met was Ruzbe Farhanipur. He's the owner of a couple of restaurants on Westwood Boulevard. We met at his Greek taverna where a shark tank was in the back of the room and the salt and pepper shakers had little Greek figures on them.

[Ruzbe Farhanipur]

I was here the time of the Khamenei killed. We heard the news. I was suspicious. That's not true because sources I couldn't trust until President Trump put it in his own truth. Social.

[Aaron Braun]

But Ruspa is not just a restaurateur. He was an opposition leader in Iran and he fled the country after leading a student uprising in 1999. For decades he's been living in Los Angeles.

[Ruzbe Farhanipur]

TV was here. I opened the grab the bottle of champagne and open it and drink it up. So that's on the tv. So that was so. And then after that, anybody passed by came to congratulate me. I poured the champagne for them.

[Aaron Braun]

It's important to say that the Iranian diaspora is vast and diverse. It's multi ethnic and multi religious and multi generational. People have very different opinions on how this war should proceed. Elham Yaguvian is an activist and a local business leader in Beverly Hills. She is desperate for the regime to fall.

[Elham Yaguvian]

Leaving Iran in that situation wouldn't help the Iranian people because in the streets of Iran people have, you know, still in danger on every.

[Aaron Braun]

She believes America should stay the course, should keep up the bombing until the regime is absolutely crippled.

[Elham Yaguvian]

They just said it to find excuse to kill people in the streets. So no, I'm 100% disagree. This is not the right time to leave the Iranian people alone.

[Aaron Braun]

But not everybody agrees Roozbah, that restaurateur who was pouring champagne for people. He's a longtime friend of hers and he's much more skeptical of America's involvement.

[Ruzbe Farhanipur]

Advisor I could suggest that's the best time instead of waiting there to become an unending war or we get stuck in something like Iraq, Afghanistan.

[Aaron Braun]

He's worried that what's happening in Iran could one day resemble Iraq or Afghanistan become another of America's forever wars. He wants America to declare victory and stop the bombing so that Iranians themselves can take to the streets.

[Ruzbe Farhanipur]

So that's the US So that's a big victory. Cheers and leave and our ready regime.

[Aaron Braun]

But the two are united on one thing. Neither of them wants a Venezuela like outcome where the President picks a more pliable member of the regime to run the country. They believe Iranians should determine their own future.

[Elham Yaguvian]

Honestly, I believe that choosing the leadership for Iran it should be in control of the Iranian people. Not west, not Israel, no, no one else.

[Aaron Braun]

Support for Donald Trump and his aggression might weaken as the war drags on. It already feels like the celebrations are subsiding in Westwood. I went to a concert at UCLA in advance of Nowruz, the Persian New Year about a week after the start of the war. The first song the orchestra played was a funeral march in honor of the protesters the regime had killed in January. The music projected sorrow but also resilience.

[Unknown Male Interviewer]

So I don't know if you've seen the program Breaking Bad.

[Rosie Blore]

Ainslie Johnstone is a data journalist.

[Unknown Male Interviewer]

The idea is that this mild mannered chemistry teacher is diagnosed with cancer. The and to try and provide for his family and to pay for his treatment, he turns to a life of crime and becomes a drug lord.

[Unknown Speaker]

What I'm making is classic coke.

[Unknown Male Interviewer]

All right, there's a recent study that shows that this plot may not be as outlandish as it seems.

[Rosie Blore]

Okay, and how did you work that out?

[Unknown Male Interviewer]

So it was a study by researchers based in Denmark and the Netherlands, and they used administrative data for the whole of the Danish population between 1980 and 2018. They specifically looked at people who at some point during this time were diagnosed with cancer. And they found that Those people were 14% more likely to commit a crime after their diagnosis, compared with people who were yet to be diagnosed with with the condition. Interestingly, they found that in the year of and immediately following their diagnosis, they actually were a bit less likely to commit crime, probably because they were in treatment, or maybe they were actually acutely unwell in this time. But what they found was then following this after a few years, and then extending for a whole decade after the diagnosis, the likelihood that the patient became involved in crime increased by a lot.

[Rosie Blore]

And what kind of crimes are we talking about?

[Unknown Male Interviewer]

So the biggest absolute increase was in what the authors called economic crimes. So that was things like drug dealing and burglaries. And that gives some hints to what the motivations might be. So they think that people may turn to crime because of money problems. In Denmark, even Denmark that has a great social welfare system, people after a cancer diagnosis are less likely to be employed and they're likely to have a lower income. But also they found that as well as these economic crimes, violent crime also increased. And this was actually the biggest percentage increase. They found that things like homicide and assault rose by 21% after a diagnosis.

[Rosie Blore]

That's a massive increase. Was there some history of criminal past or something else going on as well?

[Unknown Male Interviewer]

So, no, they found that the effect was basically the same whether someone had a history of criminality or whether they were a first time offender. But there were other predictors that kind of moderated this effect. They found that people who were particularly financially vulnerable, so perhaps people who don't own a home, people who are single, that they were the most likely to have an increase in crime rate. They also found that during the course of the study, there was this change in the municipal level welfare benefits. Some municipalities became more generous and others became less generous. And what they found was that in the places where welfare became less generous, there was again a bigger increase in criminality. The other predictor was patients prognosis. So patients who were diagnosed with more severe forms of cancer, cancer that was more likely to be lethal. They were the ones in which offending rose the most sharply. The authors think maybe this is that these People, they think they have a shortened lifespan and the idea of going to prison just maybe is less of a threat to them.

[Rosie Blore]

What about other diseases? Have they looked at that? Other life threatening illnesses?

[Unknown Male Interviewer]

They haven't looked at other life threatening illnesses. The reason they looked at cancer was because it's a very clear diagnosis. There's lots of different types of cancer. It affects people across income levels. But the idea is that this may well generalize to other diseases as well. And the gender split, Gender was a very important predictor. So men tend to commit a lot more crime, particularly a lot more violent crime. And the effect of cancer on crime was much bigger in men, so they had this much greater increase after diagnosis.

[Rosie Blore]

And how might these sorts of consequences play out in other parts of the world?

[Unknown Male Interviewer]

So when I spoke with one of the authors of the study, she said that in her mind, these results were really a kind of lower bound estimate of this effect. So as I mentioned there, looking at Denmark, it has this very generous social welfare policy. And the authors think that in places where there is maybe less of a social safety net, that this effect might be greater. And I think the effect on crime is just not something that governments think about when they're designing healthcare and welfare policies. And maybe they should.

[Rosie Blore]

Ainsley, thank you very much.

[Unknown Male Interviewer]

Thank you.

[Jason Palmer]

That's all for this episode of the Intelligence. We'll see you back here tomorrow.
