Good morning, Martijn, and welcome to Commodity Conversations. You have had a 27-year career with Cargill. From 1997 to 2006, you traded grains and oilseeds and then moved to the cocoa desk, where you became head trader. In 2022, you moved internally to spend one year as Cargill’s Trading Technology Adoption Head before leaving the company in 2023. After such a successful trading career, why did you leave active trading?
I had been wondering what I wanted to do over the next five or ten years. People asked me how I could still sit at a trading desk after so many years, but trading was my life. The years flew by quickly because I genuinely enjoyed them.
Covid changed everything. Working from home was a reset for me. I have a daughter of 14 and a son of 12. My relationship with my son wasn’t that great. It was okay, but not as good as my relationship with my daughter. I thought it was him, but during Covid, I realised it was me. I had spent too little time with him.
I had always prioritised trading and Cargill. I was never there for him for the school events. During Covid, I saw who he was and met his friends. I thought, ‘Okay, am I going to spend another 5 or 10 years on that trading desk doing the same thing?’
The whole Covid situation was a blessing in disguise for me.
Don’t get me wrong. I was passionate about trading. I was used to the lifestyle and loved what I was doing. But I realised that I loved my family more.
Was it a difficult decision to make?
Yes. I always saw myself as Mr. Cargill, but suddenly, I realised I needed to think about myself and my family.
But trading was all I knew. After 25 years of trading, I thought, ‘What the hell am I going to do to make the change I want?’
I talked with people in the company who were higher up, and they offered me a position in technology. I had been involved in a technology project for my team and had enjoyed it. I leapt at the chance of doing similar projects across the company.
The one year I spent in technology was a soft landing, allowing me to prepare to leave Cargill without endangering my 25-year career. I had a superb manager, and it was a fantastic period for me. I liked being still in Cargill, but outside of the trading side. It gave me a year to think about what I wanted to do.
What did you want to do?
I wanted to move away from the trading desk. I wanted to move away from a corporate environment. I wanted to stay involved in the commodities industry.
I have always enjoyed interacting with youngsters, and I realised that one of the things that I liked more than the market itself was developing people.
Then I thought, ‘Okay, recruiting, that is what I like.’ But it took me about a year to figure it out. I also came up with the idea of the podcast.
So, I thought, you know what, there is a space for me in the industry as a recruiter. I have a wide network. I know what I’m talking about. I’ve been a trader for 25 years. I speak the language of the client and the candidate. I have a genuine passion for people.
Do you enjoy what you are doing now?
Yes. I enjoy assessing someone’s profile, conducting interviews, and advising clients on who to hire and who not to hire. I’ve been doing this for over a year.
I enjoy making my own decisions and running my own agenda. I can choose who I work with. I especially like talking to young people; they keep me updated with the latest technology and what is important to them.
After leaving the corporate environment, I realised that independence and entrepreneurship give you freedom. It doesn’t mean that things are easy. You must do everything on your own, and it can be lonely. Even so, I wouldn’t want to trade that anymore for the certainty of a fixed salary and being in a big organisation.
Do you also give risk management advice?
Yes, I also advise on risk management. These past two years, the coffee and cocoa markets have gone up in flames, and people have become more aware of their risk exposure.
Many companies now realise that they lack a proper, formal risk policy and have limited knowledge of derivatives and risk management practices. These companies call me and ask me for advice. I like this part of my business because I can share my experiences from working at one of the best companies in the world. I explain how I have survived and thrived through market cycles.
It is the beautiful thing about Cargill. It opens doors. It gives you a stamp of approval for two reasons. The first is integrity. Everyone knows you have integrity if you’ve been successful in Cargill for a long time. And secondly, yeah, you’ve learned from the best.
Did you get withdrawal symptoms from the market when you stopped trading? Was it a drug for you?
I enjoyed it for an extended period but was also consumed by it. Now, I look at the market but don’t need to trade it. I can just analyse it. I no longer feel the pressure of having a position or not having a position.
Do you still follow the cocoa markets?
I find the cocoa market intellectually interesting. It is niche – small compared to grains and energy. Everyone knows chocolate, but few people understand what’s behind it.
Over the years, I’ve learned how the market works, but I’m still passionate about it. I write about it regularly on LinkedIn, and every two weeks, I write a cocoa market report on Vesper, the commodity insights platform.
I once started to write a book about cocoa to complement the ones I had written on coffee and sugar. But I abandoned the project. I found it too depressing. Cocoa has everything wrong with it: deforestation, child labour, land rights, producer poverty and corruption. Is it a supply chain without hope?
There is incompetence, corruption, and mismanagement in origin countries, often at the expense of millions of farmers and their families.
One of the most tragic things about this industry is that it has changed very little. It’s why you see the frustration during all these events discussing sustainability. Corruption is the elephant in the room, but no one dares to mention it.
Where does all the money go? It’s not spent on cocoa infrastructure, and farmers are not benefiting from recent high prices.
What happened last year has been years in the making: years of corruption and underinvestment. The Ghana government should conduct mass spraying programmes to tackle pests and diseases, but it hasn’t done that for years.
During my travels, I always wondered why nothing was changing. The problem is that in societies where corruption is a business model, people have no incentive to change.
How did you cope with that as a trader?
I had a pragmatic approach. The world is a complex place. You have challenging geographies where morals, rules, and life views differ dramatically from those in the West. The media condemn traders who operate in these areas, but they have no idea that much of what we consume in the West originates from these places.
If the consumer demands these commodities, someone must move them from where they are grown or mined to where they are consumed. Traders make that possible by applying enormous capital and taking risks. In doing so, we provide employment in origin countries and processing factories.
Commodity trading is one of the most critical pillars of the global economy. Without commodity traders, there would be no energy, food, or metals. Energy, metals, and agriculture build, move, and feed the world. I have always felt proud of the job I did and the company I worked for. We operated with integrity in challenging circumstances. Journalists don’t realise that trading companies are full of good, ordinary people who do their work with honesty and integrity.
Commodity trading companies must make money to survive. None of them are too big to fail. No one will save us like they did with the banks in 2008.
We have nothing to hide. We should be more open and show our customers, the media, and potential and actual employees what a great business ours is. The problem is that the media looks for the nasty sides, constantly condemning and always sitting on their moral high horse.
ADM left the cocoa sector for reputational reasons, but Cargill stayed. Cargill is an ethical company, and it’s always surprised me that Cargill continues to take the reputational risk of remaining in the cocoa market. How do you account for that?
I do not believe ADM left cocoa for reputational reasons.
Cocoa is a tricky business; trading and processing cocoa and manufacturing chocolate is complex. Cargill likes complex businesses. We always said that complexity gives opportunity. I greatly respect ADM, but they are less sophisticated than Cargill. They prefer the grain and oilseed business; it is more straightforward.
In my years, it was rare to make much money on processing. We usually made the money by merchandising, trading around assets and taking positions. I believe ADM struggled with that. They are more processing-based and do less trading. You can’t run a cocoa and chocolate business just processing. The margins are too thin.
Another point is that cocoa is capital-intensive.
Is cocoa an ingredient or a commodity?
Cocoa is a commodity, but it’s also sometimes called the anti-commodity, meaning it lives its own life. It’s not correlated to anything. To some extent, it’s an attraction. Hedge funds sometimes put cocoa in their portfolio to reduce correlation and risk.
Cocoa is not a standard product like soybeans. It has many different origins and grades. There is not one type of cocoa.
You discover that when you want to make a cash conversion and deliver physical cocoa to the futures market. It makes a difference whether you deliver beans from Ivory Coast or Cameroon. Still, it also makes a lot of difference when you use them in your factory, whether for cocoa processing or semi-finished products, for powder, liquor or chocolate.
Does having so many different grades make it easier to manipulate the market – if there’s a lack of deliverability, for example?
Yes, it has been an issue for many years. I moved from trading soybean oil on the CBOT, a well-regulated market, to trading cocoa on LIFFE. Everything I learned in Cargill about being a good actor and compliant did not exist then in the cocoa market. The business model of several players was to squeeze or corner the market at the expense of bona fide hedgers.
If a futures market loses its role as a risk mitigation tool, you cannot contract forward business. You kill the market.
Is that the main difference between grain and oilseed trading and cocoa trading – that it can be squeezed?
There are many differences, and I think any market can be squeezed.
When I started in cocoa, there were no delivery limits. It was a problem. Now, there are delivery limits. Traders can’t take delivery of a large amount simply to squeeze the market.
What are the other differences?
One critical difference is that cocoa is a tree crop; you can’t quickly grow more after a price hike.
What also makes it different? There’s no alternative. There’s no substitute. When I was trading vegetable oil, and I sold to Unilever for their margarine business, I knew that at specific price points, they would switch from soy to rape or vice versa. In cocoa, there’s no substitute.
Cocoa is not a staple food like wheat, corn, and soy, yet demand is price inelastic. People like to have this small, affordable luxury treat. It helps that it’s still cheap. You can still buy a € 1 chocolate bar. It is rare for chocolate demand to decline.
Cocoa shares some similarities with coffee, with 60 to 70 percent of the global supply coming from two countries—Brazil and Vietnam for coffee and Ivory Coast and Ghana for cocoa. However, this makes it more risky.
What is also interesting is that you have two futures markets. If you look at coffee, you have robusta and arabica. In soybeans, you have beans, meal, and oil futures. In cocoa, you have only beans.
Most commodity traders trade the basis, the price differential between the physical commodity and the corresponding futures month. Cocoa is unique in that you trade a ratio, which is a multiplier versus the futures market, not the difference. It gives an entirely different dynamic with implications regarding hedging and your flat price exposure.
What does it take to be a good trader? What would you look for if hiring a trader for your desk?
The first thing I look for is a natural interest in financial markets. I always ask people what kind of news interests them, what the first website they open in the morning is, and what newspapers they read. I also ask if they have any exposure to the financial markets. Is it an ETF? Is it in individual stocks? Is it crypto? I ask them about current Fed policy and their opinion on it.
Why is this so critical? It goes back to what I said earlier about why I stayed 25 years on a trading desk; it naturally interested me. If you are interested, it doesn’t cost you energy. It gives you energy. If you are not naturally interested, you can manage it for a while, but not for long. Trading is so intense you can only endure it if you’re naturally interested.
You want a debate on a trading desk. The life of a trader, to a large extent, is reading, thinking, debating with other naturally interested people, and then coming to a conclusion and translating that into a risk-bearing position in the market.
You need a risk appetite. I once talked with one of the leads in Cargill, Geneva. He said, “There are people who trade not to lose, but we want people who trade to win.” People may find this strange, but having an appetite for risk does not mean gambling.
The best traders are great risk managers and consistent. It’s not about having the market right for one or two years; it’s about being right for 25 years.
Curiosity is vital. You must have an open mind and be pragmatic, not dogmatic. However, you must be confident to endure the market telling you you’re wrong.
The best traders I know are modest, mundane people with no ego. Not having an ego also means not taking things personally. When you’re wrong, you get out. It’s not a problem. You move on. The market doesn’t care about you or what positions you have.
As a trader, you will never have 100 or even 90 per cent certainty or conviction. But you must be decisive. Otherwise, you’re never going to do anything. So that means that there will be some mistakes, and you get that with experience. You must have the confidence to trust your judgment. It’s not arrogance. It’s not ego. It is simply what you need as a trader.
You also need to enjoy an environment where you are constantly challenged by the market and your peers, by youngsters who are more intelligent than you or have technical skills that you don’t.
I hired intelligent young people who were better in certain areas than me because I wanted them to grow and develop. Hiring smart people creates a team that constantly improves and stays relevant. It’s great when young people come up with an entirely different analysis from yours, and you realise you were wrong. It may be corporate slang, but you want a growth mindset, not a closed one.
Lastly, you need to accept that you must put the hours in.
Is letting ego get in the way the biggest mistake a trader can make?
Too big an ego can mean too big a position. When people are successful, they start to overestimate themselves. They think they are invincible.
Underestimating your competitor is a mistake. There are a lot of smart and intelligent people in this world. You must respect the person on the other side of the trade. I always thought, ‘Okay, if I’m doing this, someone else is doing the opposite. Why are they doing it?’
It is a mistake to surround yourself with yes-men.
Another is underestimating how technology can change a market. On the one hand, you can say that markets never change because they are run by human beings with human emotions, such as greed and fear.
I did a podcast with Tom Kopczynski and discussed why Blenheim closed. One reason was that they didn’t adjust their model. They had a purely fundamental model, and there are times when fundamentals don’t play a role; systematic traders and algorithmic hedge funds dominate the market.
Some of these hedge funds are technology companies. They hire people who can code and capture massive amounts of data.
That brings me to my next question: to what extent have the futures markets become computers trading with computers? Then, this follow-up question: Will AI take over trading while humans are left to do the physical merchandising?
Most managed money categories moved to algorithmic black-box trading long ago, a trend that has been in place for years.
There is a difference between trading and execution. Algorithms execute 90 per cent of all trades in the futures markets. Still, I think you refer to fully automated algorithms that not only execute the trades but also analyse the market and create the game plan. We looked at this at Cargill and realised that AI made it inevitable. Computers can quickly analyse a vast amount of data and see correlations that a human wouldn’t find.
You must read The Man Who Solved The Market if you haven’t read it. Renaissance Technologies has been doing this for years. They hired the best scientists and mathematicians, but AI may be able to do a similar job in the future.
However, if everyone has access to the same computing power, they will trade their strategies till they’re arbitraged away. It’s the same as in market-making and high-frequency trading. At some stage, margins will decline because people see free money, and free money doesn’t stay long in the market.
Speculators are essential because they provide liquidity, but depending on the market size, they can also eventually obstruct. That is where regulation comes in. We have moved past having free, unregulated markets where the interest of a few can destroy a whole market.
I wanted to return to your comment about respecting the person on the other side of the trade.
It is essential to come out of your bubble regularly, your internal bubble from being in your company with your views and how you do things.
Cargill is one of the best companies in the world. We were everywhere. We had the best information and some of the best people, and I often felt my market view was correct. It was the truth. But then I would spend time in London with the cocoa community, and I thought, ‘Shit, I should be here every day.’
Once you are outside your bubble, you hear many different views. It’s what makes a market. You listen to things about the market and people’s positioning. The funny thing is that you understand that the trade is sometimes not even with a company; it’s with a person.
If you know a person, you know how they might try to influence you. You also know how they react under different market situations. What have they done in the past? You can have an S&D, but someone with a massive position can be more critical than your S&D.
You also learn to see whether someone is in a good or bad position. You see it in the person and hear it in their voice on the telephone.
The problem when trading against machines is that you cannot call them on the phone. Still, it is essential to understand what drives them. That was one reason we started implementing systematic strategies at Cargill. We wanted to know why they were positioned like this. What did they see?
What is one piece of advice you would give to someone wanting to get into the commodity trading business?
Listen to the Strong Source Commodity Podcast. You will hear true stories from people who are not trying to sell you anything but genuinely want to share their knowledge. Listen to the podcasts and be honest with yourself. Yes, it excites me. It interests me. I can’t stop listening.
But if you think, well, actually, I’ve listened to maybe three, and I need to push myself to listen to a fourth, then do some soul searching as to whether commodity trading is for you. Perhaps it is not your cup of coffee.
And what one piece of advice would you give to someone on their first day on a trading desk?
Ask questions and make sure that you understand the things that the others are discussing on the desk.
A trading environment differs from anything you have experienced at university or online. It’s not unusual to be lost and feel you’ll never understand what is going on or being said. Every trader started not understanding things.
Trading is such a different environment. You do not learn to think like this at university, let alone on an online course. There are good courses in Rotterdam and Geneva, but you learn trading by doing.
