The Inquiry

Global oil markets have been affected by the US Israel war with Iran, leading to higher jet fuel prices and increased attention on supply risks. But how serious is the situation? While some experts point to tightening supply chains and regional bottlenecks, others say there is no clear evidence so far of immediate shortages. Even so, the refining and distribution of jet fuel remains a potential vulnerability, as disruption can have notable impacts even when crude oil itself is available. With air travel crucial to trade and tourism, the resilience of fuel supply is a growing concern for economies and travellers. Can alternative suppliers and fuel sources help limit the impact of future disruption? This week on The Inquiry, we’re asking: are countries really running out of jet fuel?

The recent Nasa Artemis II crewed mission to the far side of the Moon is a further step towards a long-term return to the lunar surface and future missions to Mars. The plan is that before the end of the decade there will be a crewed landing and the start of a Moon base. China is among those developing similar plans. Previous missions both crewed and uncrewed have provided evidence of resources that potentially could be of use here on Earth, and support human life on the Moon. So, it’s not just the race to the Moon that’s capturing the world’s attention, but also the possible economic benefits that that might bring with it. The Moon’s surface or lunar regolith contains volatiles like hydrogen, carbon dioxide and methane. There is evidence of minerals such as silicate and oxides and metals like aluminium and titanium, which could be extracted for building materials. And something that is rare on Earth, Helium-3, a potential resource for clean fusion energy. Governments in conjunction with private corporations are already working on the technology to extract these resources. Concerns have been raised about the potential damage to the Moon, not only in terms of the depletion of its resources, but in terms of its scientific value and its cultural heritage. Protection ranges from established treaties that prohibit ownership of the moon, to national laws that permit resource extraction. But to date, there is no universally accepted international law in place, which explicitly permits or prohibits lunar mining. So, this week on the Inquiry, we’re asking ‘Should we mine the Moon?’ Contributors: Dr Dylan Mikesell, principal geophysicist, NGI-The Norwegian Geotechnical Institute, Oslo, Norway Dr Justin Holcomb, assistant research professor, Kansas Geological Survey, University of Kansas, USA Prof Dr Thomas Zurbuchen, director of ETH Space, Swiss Federal Institute of Technology, Zürich, Switzerland Dr Tanja Masson-Zwann, assistant professor and deputy director, International Institute of Air and Space Law, Leiden University, The Netherlands Presenter: William Crawley Producer: Jill Collins Researcher: Evie Yabsley Editor: Tom Bigwood Technical Producer: Nicky Edwards Production Management: Phoebe Lomas and Liam Morrey (Photo: The Moon.

Conflict in the Middle East has led to volatility in global oil prices, pushing up fuel costs worldwide. Previous oil shocks prompted some countries to reconsider their reliance on cars, investing in alternatives such as cycling. In some places, this has become part of everyday life, while elsewhere it has proved more contested, reflecting wider political and cultural divides. Cycling offers benefits for health and the environment, but it is not practical for everyone. For many people, including those in rural areas or with limited mobility, cars remain everyday essentials. As oil price volatility continues to affect motorists, questions remain about how far behaviour can change. This week on The Inquiry, we’re asking: is it time to swap four wheels for two?

Broadcasters from The Netherlands, Ireland, Iceland, Spain and Slovenia are all boycotting May’s Eurovision Song Contest because Israel is participating. Sources within Israel’s broadcaster say calls for it to be banned are unjustified, and organisers of the contest insist it must remain politically neutral, describing the event as "a platform for displaying the importance of peace and unity in a divided world". More than 160 million watch each year, and it is a competition between public service broadcasters - including the BBC - and not one between governments. The boycott has sparked one of the biggest crises in Eurovision’s 70-year history. In several cases, the position to withdraw also reflects wider pressure from politicians and public opinion. This week on The Inquiry we’re asking: ‘How will countries boycotting Eurovision affect the contest?’ Contributors: Natalija Gorščak, president of the management board of RTV, Slovenia Dr Bárbara Barreiro León, lecturer in film and visual Culture, University of Aberdeen, UK Dr Heather Dichter, associate professor of sport history and sport management, De Montfort University, UK Dr Dean Vuletic, author Postwar Europe and the Eurovision Song Contest, Luxembourg Presenter and Producer: Daniel Rosney Editor: Tom Bigwood Technical Producer: James Bradshaw Production Management: Phoebe Lomas and Liam Morrey (Photo: Eurovision flags.

For the second time in 12 years Glasgow is preparing to host the Commonwealth Games after Australia’s Victoria state pulled out because of increased costs. Victoria’s withdrawal raised questions about whether the 2026 games would go ahead before Glasgow agreed to step in. Staging a sporting mega-event is expensive and governments face increasing scrutiny over public spending. Victoria’s decision raised wider questions about affordability for potential hosts. At the same time, critics question the Games’ political relevance, given its origins in Britain’s colonial past. The Commonwealth Games Federation says the event can be delivered in a more sustainable way and argues that it brings cultural and economic benefits to host cities, but recent editions have run into significant costs and budget pressures. This week on The Inquiry, Tanya Beckett asks ‘Is it time to scrap the Commonwealth Games?’ Contributors Dr Stuart Whigham, Senior Lecturer in Sport, Coaching and Physical Education at Oxford Brookes University, UK Dr Matthew McDowell, Lecturer in Sport Policy, Management, and International Development at the University of Edinburgh, UK Dr Verity Postlethwaite, Lecturer in Strategic Event Management at Loughborough University, UK Professor Gayle McPherson, Associate Dean for Research at the University of the West of Scotland, and Director of Legacy and Community Engagement for Commonwealth Games Scotland, UK Presenter: Tanya Beckett Producer: Matt Toulson Researcher: Evie Yabsley Technical Producer: Craig Boardman Editor: Tom Bigwood Production Management: Phoebe Lomas and Liam Morrey (Photo: Commonwealth Games Gold Medal.

Ireland has a new permanent government scheme providing regular cash transfers to 2,000 artists. The people who can access it range from circus performers to opera singers. It follows a pilot of more than three years which is believed to have brought a return on investment to the economy. Big tech backs basic income schemes like this to offset the consequences AI is having on the workforce. Leading economists believe it could create a dystopian world. Nevertheless, more governments are piloting or planning to introduce schemes like this. This week on The Inquiry, we’re asking ‘Why is basic income being debated?’ Contributors: Dr Jenny Dagg, assistant lecturer, Maynooth University, Ireland Dr Catarina Neves, postdoctoral fellow, Utrecht University, The Netherlands Daron Acemoglu, 2024 Nobel Prize winner in economics, institute professor, Massachusetts Institute of Technology, US Jurgen De Wispelaere, acting chair of the Basic Income Earth Network Presenter: Charmaine Cozier Producer: Daniel Rosney Researcher: Evie Yabsley Editor: Tom Bigwood Technical Producer: Craig Boardman Production Management: Phoebe Lomas and Liam Morrey (Photo: A customer withdraws euro bills from an ATM in Sofia.

Cuba is facing one of its most severe humanitarian crises in decades. For years, Cuba relied heavily on oil from Venezuela. Those supplies have largely stopped, contributing to widespread fuel shortages. Electricity blackouts have become increasingly common, disrupting daily life across the country. The United States has blocked fuel shipments to Cuba as part of wider pressure linked to its economic and political policies. Meanwhile, the Cuban government has warned it will resist any external interference in its domestic affairs. With economic strain growing and living conditions worsening, this week on The Inquiry, we’re asking: ‘Is the revolution in Cuba over?’ Contributors: Lillian Guerra, professor of Cuban and Caribbean history at the University of Florida, US Ricardo Torres, research fellow at American University, US Christopher Sabatini, senior research fellow for Latin America at Chatham House, UK Renata Segura, programme director for Latin America and the Caribbean at the International Crisis Group, US Presenter: Tanya Beckett Producer: Matt Toulson Researcher: Evie Yabsley Editor: Tom Bigwood Technical Producer: Cameron Ward Production Management: Phoebe Lomas and Liam Morrey (Photo: Havana, the capital of Cuba, during a blackout in March 2026.

Rewilding, or letting nature take care of itself, can restore stability to damaged ecosystem components which support life on earth, like fungi, bacteria, vegetation, insects and animals. But there's now a wider discussion to discover what it’s capable of on a wider scale. International agreements for reducing the impact of climate change tend to set global targets. However, individual governments decide how to work towards meeting those goals at a national level. Some rewilding initiatives improve biodiversity, but it can have negative impacts too. This week on The Inquiry, we’re asking ‘How can rewilding help combat climate change?’ Contributors: Carolina Soto-Navarro, head of Wilder Nature at Rewilding Europe Brendan Fisher, professor in the Rubenstein School of Environment and Natural Resources, at University of Vermont, US David Nogues Bravo, professor in biodiversity, University of Copenhagen, Denmark Steve Carver, professor of rewilding and wilderness science, University of Leeds, UK Presenter: Charmaine Cozier Producers: Jill Collins and Daniel Rosney Researcher: Evie Yabsley Editor: Tom Bigwood Technical Producer: Cameron Ward Production Management: Phoebe Lomas and Liam Morrey (Photo: Galapagos giant tortoise.

In February, Polish Prime Minister Donald Tusk posted a social media video celebrating new figures from the International Monetary Fund suggesting that the average person in Poland now has slightly more spending power than the average person in Spain, the European Union’s fourth largest economy. It’s a symbolic milestone for a country that emerged from communism just over three decades ago and once struggled with hyperinflation and economic upheaval. In 2025, Poland’s economy also passed the trillion-dollar mark, putting it in an elite group of just 20 countries globally. Investment from across the EU has helped drive growth. But can Poland keep its edge as labour shortages grow and the war in neighbouring Ukraine continues to shape the region? This week on The Inquiry, Tanya Beckett asks: Why is Poland’s economy booming?

Half a million people are in Spain without official permission. They come mainly from Colombia, Peru, Honduras, Paraguay, and Argentina. It’s thought that most outstay their work, student, or tourist visas. An amnesty to grant them legal status to remain and work is due to start within weeks. It's a very different approach from most other countries in Europe that have been tightening controls on migration. The prime minister has admitted “Some say we've gone too far, that we're going against the current”. Opposition parties argue that this policy puts pressure on public services. This week on The Inquiry, we’re asking: “How will Spain’s migrant amnesty work?” Contributors: Ismael Gálvez Iniesta, assistant professor, department of applied economics, Universitat de les Illes Balears, Spain Donna Cabrera, independent researcher, international migration lecturer, Pontificia Universidad Javeriana, Colombia Alana Moceri, international relations professor, IE University, Spain Joan Monràs, economics professor, Universitat Pompeu Fabra, Spain Presenter: Charmaine Cozier Producer: Daniel Rosney Researcher: Evie Yabsley Editor: Tom Bigwood Technical producer: James Bradshaw Production Management: Phoebe Lomas and Liam Morrey

Control of critical minerals is becoming a source of geopolitical tension. They are essential to modern technology and industries around the world, and China currently dominates the mining and processing industry. As demand grows, governments in the United States and elsewhere are looking at ways to reduce their reliance on Chinese supply chains. That means investing in new mines and processing facilities even though they are expensive and environmentally toxic. Ultimately, the US and EU have a goal of diversifying the control of these lucrative elements. This week on The Inquiry, Tanya Beckett explores whether the rest of the world can catch up with China in the race for rare earths.

The 2026 men’s football World Cup will be the biggest ever staged. For the first time, 48 teams will compete, playing more than 100 matches across North America. But the expanded scale comes at a cost. Ticket prices are far higher than at the last World Cup in Qatar. With matches also spread across the US, Mexico and Canada, attending the tournament is becoming unaffordable for many global fans. FIFA says higher revenues will be reinvested to grow the game worldwide and has released some lower-priced tickets for dedicated supporters, but some fan groups say this isn’t going far enough. This week on The Inquiry, we’re asking: Is the 2026 World Cup an own goal?

Chennai, São Paulo, Mexico City, Tehran, Cape Town - these cities have all faced the threat of a ‘Zero Day’, or, having no fresh water left in their taps. The UN says we’re entering a ‘water bankruptcy’ era, meaning our water ‘current accounts’ are running empty, while our ‘savings accounts’ - the long term stores of water deep underground - have been depleted, with some beyond repair. So how did we get here? From clearing forests for cattle grazing, to thirsty AI data centres, Rajan Datar examines the pressures on our global water supply and looks for solutions.

Bangladesh will hold a national election in February, after years of political turmoil and the ousting of long-time leader Sheikh Hasina. Her rule of more than a decade delivered strong economic growth but was also accompanied by tighter political control and repeated confrontations with protesters. Sheikh Hasina’s party, the Awami League, has been banned. This has brought renewed focus on the Bangladesh Nationalist Party’s leader Tarique Rahman, who is the son of former prime minister Khaleda Zia, as well as several emerging challengers. Following years of unrest, the vote is seen as a test of whether Bangladesh can move towards political stability. This week on The Inquiry, we’re asking: What does the national election mean for the future of Bangladesh?

Boosting, swiping or the five finger discount - many countries around the world are seeing a rise in retail theft. From Japan to the UK, the USA to Germany, retailers are struggling to tackle shoplifting - but the factors fueling this trend are as varied as the people carrying out these crimes. Poverty, opportunism, thrill-seeking - and technology - are some of the factors experts say are to blame. But a more costly problem is the rise in organised crime, as gangs of thieves strategically target shops and steal to order, turn to online marketplaces to anonymously sell on stolen goods for big profits. Charmaine Cozier reveals how the justice system and surveillance technology are being used to combat this rising crime wave, as The Inquiry asks what’s behind the rise in shoplifting?

Iran has been shaken by protests on a scale not seen since its 1979 revolution. Demonstrations that began in the country’s capital over the state of the economy have spread to multiple cities, with wider calls for political change. The government has called the demonstrations "riots" backed by the nation’s enemies. Thousands have been killed. For some, the scenes bring back memories of the uprising that toppled the monarchy more than four decades ago. Crown Prince Reza Pahlavi, the exiled son of Iran’s last monarch, has emerged as a figure that could challenge the existing order. This week on The Inquiry, we’re asking ‘Is history repeating itself in Iran?’ Contributors: Naghmeh Sohrabi, modern Middle East historian, director for research at the Crown Center for Middle East Studies at Brandeis University, United States Azadeh Kian, author of ‘Rethinking Gender, Ethnicity and Religion in Iran’, emerita professor of sociology and gender studies at the University of Paris Cité, France Sara Bazoobandi, non-resident research fellow at the Institute for Security Policy of Kiel University, Germany Siavash Ardalan, BBC Persia senior reporter, United Kingdom Presenter: Daniel Rosney Producer: Megan Lawton Technical producer: James Bradshaw Editor: Tom Bigwood Production Management: Phoebe Lomas and Liam Morrey (Photo: Car on fire on a street in Iran.

In February 2026, the last remaining nuclear arms control treaty bilateral between Russia and the United States is set to expire. The aim of the New START agreement was to reduce and limit the number of strategic nuclear warheads, but once this treaty comes to an end it means there will no longer be rules on the cap of these nuclear weapons. The legal provisions in the treaty for a one-time five-year extension, were used in 2021. The multilateral Nuclear Non-Proliferation Treaty (NPT) is still in place, to which 190 countries are signatories. The general idea behind the NPT was for nuclear countries to reduce their stockpiles of nuclear weapons, with the goal of complete disarmament. Whilst those countries without nuclear weapons would commit to not pursuing them. In 1995 the members agreed to extend the treaty indefinitely, but it is not without its challenges. Four nuclear powers sit outside the NPT and there are rifts between the non-nuclear and nuclear states. So, on The Inquiry this week we’re asking, ‘Is nuclear disarmament set to self-destruct?’ Contributors: Hermann Wentker, Professor of Modern History, University of Potsdam and Head of Berlin Research Department, The Leibniz Institute for Contemporary History, Germany Alexandra Bell, President and CEO, Bulletin of the Atomic Scientists, USA Mike Albertson, arms-control expert, former negotiator on New START arms reduction treaty, USA Nathalie Tocci, Professor of Practice, Johns Hopkins SAIS (School of Advanced International Studies), Italy Presenter: Charmaine Cozier Producer: Jill Collins Researcher: Evie Yabsley Production Management Assistant: Liam Morrey Technical Producer: Richard Hannaford Editor: Tom Bigwood (Photo: Deck of the nuclear submarine Saphir.

Kenya is facing rising public discontent over allegations of political corruption, economic stagnation and a shortage of good quality jobs, particularly for the country’s Gen Z. One of the government’s flagship responses is an ambitious push into digital outsourcing. It argues that call centres, coding work and other IT-enabled services can position the country as a global hub and generate a million new jobs within five years. The model has worked before in countries such as India and the Philippines, but the global landscape is shifting. Advances in artificial intelligence are already transforming the very roles Kenya hopes to attract, raising questions about whether this strategy can deliver long-term employment at scale. Tanya Beckett asks whether Kenya’s vision for digital outsourcing can provide stability and opportunity for the country. This week on The Inquiry, we’re asking: Can Kenya answer the call for employment?

Taylor Swift’s Eras Tour shattered records, becoming the highest-grossing concert tour of all time, redefining what’s possible and confirming a new era in the business of touring. As streaming transformed how we listen to music, selling records is no longer the financial centrepiece it once was for artists. Instead, exclusivity has been transferred to the live experience. But staging shows on this scale requires enormous investment and complex production. At the same time, ticket scarcity fuels extraordinary demand and rising prices, which mean big ticket prices. Tanya Beckett explores how technology, fandom and economics turn modern concert tours into multi-billion-dollar ventures. This week on The Inquiry, we’re asking: How did music megatours become such a money spinner?

Christmas is a time of year when many families and friends come together for a period of joy, peace and goodwill. The story of the birth of Jesus Christ has been translated into thousands of languages over thousands of years. And while you may hear it differently, the message is the same. From carols to conversations, Christmas reminds us how united we can be. But there’s still one thing that sets us apart and prevents us from truly understanding one another - language. Esperanto, created in the late 1800s, was the most ambitious direct attempt at creating a singular way of speaking. Its struggle to spread beyond a committed community shows us how deeply languages are tied to identity, power and history. This week on The Inquiry we’re asking: Will there ever be a single global language?
