We often hear that the United Nations is where the world's biggest problems get solved. But here's the uncomfortable truth: the institution itself is facing a crisis of legitimacy, and whoever is chosen to lead it from January 2027 will inherit that crisis directly.
One of the leading candidates in that race is Rebeca Grynspan, a 70-year-old Costa Rican economist. Her candidacy deserves serious attention from anyone working on youth policy. Why? Because her own vision for the UN places young people at the centre of the institution's survival.
Who Is She?
Grynspan was born on 14 December 1955 in rural Costa Rica, the daughter of Polish Jewish immigrants who arrived in Central America with almost nothing. She studied economics at the University of Costa Rica and took a Master's at Sussex in Britain. Her career since then has moved between national politics and multilateral diplomacy, with one unusual pattern. She has been the first woman to hold nearly every major role she has occupied.
She served as Vice President of Costa Rica from 1994 to 1998 under President José María Figueres, after earlier stints as Deputy Minister of Finance and Minister of Housing. At the international level, she ran UNDP's Latin America regional bureau, became UN Under-Secretary-General in 2010, and led the Ibero-American Conference from 2014 to 2021.
In September 2021, António Guterres appointed her Secretary-General of the UN Conference on Trade and Development, known as UNCTAD. She became the first woman to hold that position in the organisation's sixty-year history.
On 8 October 2025, Costa Rican President Rodrigo Chaves nominated her to succeed Guterres. Her nomination was formally submitted to the General Assembly on 3 March 2026.
The Numbers Tell a Story
To understand why Grynspan's candidacy matters for youth policy, consider what she has spent the last three years arguing about.
More than 3.3 billion people live in countries that spend more on debt service than on health or education. Global food insecurity affects 345 million people across more than 80 nations. Only a fraction of young people in developing economies can access the kind of digital infrastructure that shapes opportunity in 2026. These are not abstractions. They are the conditions that define the lives of most young people on the planet.
Grynspan's argument, delivered repeatedly in speeches and interviews, is that these crises are connected. Debt crowds out education spending. Weak education weakens labour markets. Weak labour markets push young people into migration, informal work, or worse. She frames this as a silent emergency, and she has consistently tied the UN's credibility to whether it can address it.
The Black Sea Test
Before her candidacy, Grynspan was known internationally for one specific achievement: negotiating the Black Sea Grain Initiative in 2022.
When Russia invaded Ukraine, grain exports from Ukrainian ports collapsed. Global food prices spiked. In countries already strained by pandemic-era debt, the consequences were devastating. An estimated 47 million additional people faced severe hunger.
Guterres assigned Grynspan to lead the negotiation to reopen the corridors. After months of shuttle diplomacy between Kyiv, Moscow, Ankara, and every shipping insurer and bank involved in the logistics, two agreements were signed in Istanbul in July 2022. Before the initiative eventually collapsed, it had moved over 32 million tonnes of grain to more than 40 countries, more than half of which were developing economies. Global food prices fell by roughly 23 per cent from their peak. In 2024, she received the Doha Negotiator of the Year award for the effort.
Why does this matter for youth policy? Food price shocks hit young people hardest and longest. The children who went hungry in Yemen and the Horn of Africa in 2022 have not recovered just because grain prices eventually dropped. The secondary school students who left education to help their families survive have not simply returned. When Grynspan talks about the cost of failed diplomacy, she is speaking from the experience of having watched it play out in real time.
Her Three Priorities
Every candidate for UN Secretary-General submits a vision statement to the General Assembly. Grynspan's, submitted in March 2026, organises her argument around three priorities.
The first is peace and security. She wants to restore the UN's role as a trusted convener in conflict situations, with what she calls early engagement and quiet back channelling before positions harden. She calls for properly resourced mediation capacities and data-driven early warning systems. She argues that the UN must be at the table when others leave.
The second is delivering results. She acknowledges that the UN has a performance problem, with overlapping mandates and inefficient structures, and she promises reform built around three words: more useful, more agile, more accountable. She commits to integrating AI and data analysis into UN operations, not as experiments, but as core tools.
The third, titled "Building the Future," is the one that should command the Centre for Youth Policy's attention.
What She Says About Young People
Grynspan opens her forward-looking section with an observation worth quoting in its essence. Every generation, she writes, carries a simple expectation that their children will live better than they did. In much of the world, that expectation is breaking down. Young people are entering economies that offer less than their parents had. They are inheriting a more hostile climate. They are scrolling through futures that seem to close rather than open.
This is an economist's diagnosis, not a slogan. And it frames the concrete proposals that follow.
On technology, she argues that artificial intelligence is moving faster than any technology in history and reshaping the nature of work itself. Her argument is not the familiar hand-wringing. It is that the UN must accelerate technology diffusion so that digital divides do not widen, and that young people, communities, and governments are actually empowered to benefit. Anyone who has watched AI tools collapse entry-level opportunities in professional services, or spoken with young Nigerians or Kenyans trying to enter global tech economies without matching infrastructure, will recognise why this framing matters.
On finance, she connects her 1980s Costa Rican debt-renegotiation experience to her current advocacy. Her argument is that the international financial architecture needs reform, with developing countries given real representation in institutions like the IMF and World Bank. When sovereigns spend more on interest payments than on schools or clinics, the first casualties are always young people. This is not a coincidence. It is a structural feature of how the global financial system currently works.
On climate and resources, she notes that clean energy is growing faster than anyone predicted and that critical minerals are becoming as valuable as oil. The material substrate of the next economy is being fought over right now. Young people in resource-rich but institutionally weak countries will either benefit from that transition or be crushed by it, depending on how it is governed.
The Politics of the Race
None of this gets her the job on its own. The UN Secretary-General is not elected by young people, or by publics at all. The five permanent members of the Security Council (the United States, China, Russia, the United Kingdom, and France) will decide. Any one of them can veto her. The General Assembly then rubber-stamps whoever the P5 agree on.
Some factors work in her favour. Regional rotation, while not a formal rule, suggests the role is due to return to Latin America and the Caribbean. The push for the first woman Secretary-General in the UN's 80-year history has intensified. Her UNCTAD portfolio has made her well-known in every major capital without making her anyone's client.
She also did something none of her rivals did. She temporarily stepped away from her UNCTAD role for the duration of the campaign, telling reporters that credibility is built through choices, not statements. Her main current rival, Rafael Grossi of Argentina who leads the International Atomic Energy Agency, has been criticised for remaining in his job while campaigning.
The field itself has narrowed. Michelle Bachelet of Chile was jointly nominated in February 2026, but Chile's new government withdrew support after a change of administration in March. Macky Sall of Senegal, nominated by Burundi, faces questions about political backing. Grossi has the platform but carries the conflict-of-interest baggage. That leaves Grynspan as, arguably, the most fully viable declared candidate, though the official dialogues with candidates, held at the UN on 21 and 22 April 2026, will sharpen perceptions considerably.
What works against her is harder to overcome. The Trump administration has been publicly sceptical of the UN, and her intellectual roots in structural inequality, debt reform, and the governance of globalisation are not congenial to the current American foreign-policy posture. Whether the United States vetoes her, or whether a compromise emerges later in 2026 as in previous selection cycles, remains genuinely uncertain.
Why This Matters Now
There is a tendency, when writing about Secretary-General races, to treat them as specialist games reserved for people who can recite Security Council resolution numbers from memory. That tendency is wrong.
The UN is the institution through which most global governance on youth-relevant questions actually happens. The Sustainable Development Goals, which Grynspan has publicly warned are badly off track, sit with the UN. The international response to climate change sits with the UN. The emerging governance of AI, the rules shaping how capital moves between rich and poor countries, the legal architecture that protects young people in conflict zones: all of it flows through this institution.
Whoever holds the Secretary-General's office from January 2027 onward will set the tone for all of it.
What makes Grynspan's candidacy interesting, rather than merely plausible, is that she has articulated the clearest argument of any current contender that the UN's future legitimacy depends on whether young people believe it can deliver. Her framing is that the central question of our time is whether abundance will become humanity's common inheritance or its deepest divide. That is not diplomatic language. It is an argument about who gets to participate in the economies and institutions the next several decades will build.
The selection will be made by late 2026. The consequences will last far longer than that. The question for youth policy practitioners, researchers, and advocates is whether to engage this conversation actively in the coming months, or to let it happen in rooms where young people are, once again, spoken about rather than with.
