On November 17th, 2025, SAIS Europe hosted Tim Jennison for a lecture on how financial markets are adjusting to a period of political uncertainty, fiscal strain and rapid technological change. Jennison spent nearly two decades in London at Morgan Stanley, rising to Managing Director in 2008 holding leadership roles across fixed income, emerging markets, credit sales and trading and global bank solutions before moving to the Boston Consulting Group in 2016. At BCG he served as the Global Lead for Capital Markets and Investment Banking, advising major banks on strategic positioning, organizational design and efficiency. He now runs a family office while continuing to advise financial institutions.

Jennison proposed that current market behavior can be understood through three themes that cut across policy, technology and geopolitical risk. First, he described how the return of an America First economic posture influences nearly every asset class. Protectionist trade measures, heavier reliance on domestic production and persistent fiscal expansion create an environment where supply chains tighten, corporate margins face pressure and long term inflation expectations shift. This environment also shapes market views on the stability of the dollar and the sustainability of US borrowing, particularly as central bank independence becomes part of the political debate.

Second, Jennison highlighted the rise of artificial intelligence as a central force in market pricing. Large technology firms attract significant investment because their computing scale and cash reserves position them as long term winners in a sector that investors believe will determine national competitiveness. Valuations in this area have reached historic levels, supported by strong revenue and expectations of continued dominance. Smaller firms face a different reality because they often rely on fragile revenue streams or expensive access to computing power, which creates uneven resilience across the sector.

Third, he examined the heightened sensitivity of markets to geopolitical events. Conflicts, sanctions, and shifting alliances produce immediate reactions across equities, currencies and commodities. Investors move quickly into assets that signal stability, which explains the strong appreciation of gold and the Swiss franc during the past year. At the same time, sectors tied to national security and strategic technology absorb more capital during moments of uncertainty, creating a divide between firms exposed to global disruption and firms positioned to benefit from security driven investment.

Jennison stressed that these themes interact with the technical positioning of large investors. Many institutions entered the year with limited equity exposure and every pullback created a rush to buy rather than a sustained decline. Liquidity built up during years of low rates continues to push valuations higher than traditional models would imply, which helps explain the rapid rebound that followed the early 2025 shocks and the shifts in relative performance between the DAX and the S&P 500.

Questions from the audience focused on the strength of the AI sector, the risks building in private credit markets and the fiscal trajectory of the United States and Europe. Jennison drew a clear distinction between large AI firms with strong cash flows and smaller firms that depend on narrow revenue streams or expensive computing resources. He warned that private credit carries meaningful risk because it operates outside the regulatory structure that governs banks, yet it now plays a central role in financing companies. He noted that this area deserves closer supervision as it expands. On Europe, he pointed to concerns about fiscal discipline in countries that are borrowing heavily without clear returns on investment.

Jennison closed with a reflection on the broader picture. Markets continue to move through cycles of correction and recovery and he expects those cycles to become more frequent in the near term. He argued that resilience still comes from a mix of institutional strength, liquidity and long run profitability in key sectors. Despite rapid changes in politics, technology and global alignments, he believes financial markets retain the capacity to adapt quickly and redirect capital toward areas where growth remains strong.
