This year has been a tumultuous period, both economically and politically. New U.S. tariff policies, in particular, have shaped the headlines and been one of the most defining issues of the year. Other major developments have included a backlash against diversity, equity and inclusion and a pushback against sustainability strategies.
There are several ongoing conflicts around the world and high sovereign debt levels are causing headaches for governments in many markets. At the same time, the technological revolution is continuing at pace, bringing new challenges and opportunities to organizations.
All these developments have implications for leaders. So, which leadership lessons can they take away from the events of 2025?
Leadership lesson no 1: Get geopolitically savvy
Heightened geopolitical tensions have made the world a less certain place to live, work and do business in 2025. As a result, being geopolitically savvy has become an imperative for leaders.
“The events of 2025 have reminded leaders that success today depends less on forecasting markets and more on understanding geopolitics,” says Arturo Bris, author of SuperEurope: The Unexpected Hero of the 21st Century. “Wars, sanctions and election shocks have shown that economic policy is now political risk in disguise. The first lesson for executives is to build geopolitical literacy. Leaders must invest in external intelligence networks, follow global developments directly and integrate political risk into strategy rather than treat it as a short-term disruption.”
Leadership lesson no 2: Be less referee, more navigator
“If 2025 has taught us anything, it is that resilience can no longer be treated as a buzzword,” says Thomas Keil, co-author of The Next Board: Delivering Value Today while Making the Board Fit for Tomorrow. “This year’s mix of geopolitical tension, technological disruption and shifting stakeholder expectations has tested how adaptable leaders and boards truly are.”
Keil believes that boards have had to think less like referees and more like navigators. “We have seen that strategic foresight and agility of response now matter as much as compliance and financial performance,” he says. “In particular, the global trade reset and rising geopolitical tensions have tested boards’ capability to adapt their companies’ supply chains, international strategy and even footprint. The boards that adjusted quickly didn’t just survive the turbulence; they found new opportunities in it.”
The leaders that will thrive going forward, according to Keil, are those that “stay open, ask better questions, and use change and disruption as a chance to rethink what the future of their company may really look like.”
Leadership lesson no 3: Understand AI’s thirst for power
Global adoption of artificial intelligence (AI) has been one of the major trends of 2025. Yet the rise of AI has also highlighted the technology’s intrinsic requirements for land, power and other resources. U.S. data centers alone will require 22% more grid-based power by the end of this year compared with last year and their requirements will nearly triple by 2030 compared with 2024. Hence power availability is the enabler for AI growth.
The power-hungry nature of AI means that leaders can gain a competitive edge by understanding AI infrastructure and elevating it from a back-office concern to a board-level priority. “Leaders who understand the physical realities behind digital transformation will set the pace, as those who invest early in resilient, efficient infrastructure will own the capacity to innovate when others hit grid or supply limits,” says Mehdi Paryavi, chairman and CEO of digital economy think tank the International Data Center Authority. “The organizations that will thrive in 2026 are those that treat infrastructure planning as part of their focal strategy, not a downstream operational apparatus.”
Leadership lesson no 4: Get ready to address the “trust deficit”
The 2025 Edelman Trust Barometer highlighted that trust has been eroded by the institutional failures of the last 25 years, producing a widespread sense of grievance. Three in five respondents globally (61%) have a moderate or high sense of grievance – defined by a belief that government and business make their lives harder and serve narrow interests, with wealthy people benefiting unfairly from the system.
Leaders can play an important role in addressing the trust deficit by ensuring their behavior is congruent with their word, says Ravi Rajani, a communication expert and author of Relationship Currency: Five Communication Habits for Limitless Influence and Business Success.
“People aren’t craving perfect leadership,” Rajani says. “They are craving authentic leadership. This requires leaders to show integrity about keeping their promises and – if they fall short – to consciously take full ownership. In 2026 and beyond, walking your talk will be priced at a premium.”
Leadership lesson no 5: Don’t let stress and power go to your head
“A leadership lesson from 2025? Hmmm… Don’t go to Coldplay concerts? Don’t have an affair with subordinates?” suggests Nik Kinley, a leadership consultant and author of The Power Trap: How Leadership Changes People and What to Do About It. “Or, how about not snatching gifts from children? Or, at least, don’t get caught on camera doing so, and then justify your behavior by saying the child should have been quicker.”
Kinley points out that reputational risks for leaders have grown exponentially over the past few years, with leaders under greater scrutiny than ever before, not least because of the proliferation of smartphones and social media. Leaders know the risks, however, so why are they still being caught out?
“The increasing pace and pressure of leadership is doing something to our brains,” Kinley argues. “The heavier our workloads get, the faster we have to operate and the more stressed we grow and the more prone we become to the influence of power. Power focuses us more on rewards and goals, making us more likely to take risks to get them and less empathetic to the impact we have on others along the way.”
His top leadership lesson for 2025 is this: “The problem with the pressures of work is not just the stress it causes, but the door it opens to the effects power can have upon us and what this can then lead us to do.”
