• Royal London Asset Management's newly appointed Chief Investment Officer, Will Nicoll, cautions that investors should brace for heightened market volatility.
  • Nicoll points to geopolitical tensions, economic uncertainty, and shifting sentiment around AI as key drivers of potential turbulence.
  • He underscores rising sovereign debt levels as a critical, long-term risk to fiscal stability.

In one of his first major public commentaries since taking the helm as Chief Investment Officer at Royal London Asset Management (RLAM) in December, Will Nicoll has issued a stark warning to the market. According to people familiar with his recent remarks, Nicoll believes a period of significant volatility is on the horizon, fueled by a complex mix of geopolitical strife, economic fragility, and the unpredictable narrative surrounding artificial intelligence.

Nicoll, who joined RLAM from M&G Investments where he oversaw private markets, suggested that investor sentiment is poised to swing erratically. The initial euphoria and premium valuations driven by AI advancements could quickly give way to broader anxieties about global instability, according to his analysis. This sentiment whipsaw would create a challenging environment for asset allocators trying to navigate public markets.

Perhaps more concerning is his emphasis on sovereign balance sheets. Nicoll highlighted that debt-to-GDP ratios across many major economies have ballooned to levels that would have been "unthinkable" and deeply alarming to policymakers just a few decades ago. This sustained fiscal expansion raises fundamental questions about how long governments can maintain current spending trajectories without triggering a crisis of confidence in bond markets. "The fiscal room for maneuver is not what it was," he was paraphrased as saying, indicating that this overhang will be a persistent source of risk.

The warning comes at a delicate time for RLAM, which manages over £150 billion in assets, as it seeks to stabilize its investment leadership. Nicoll's appointment last year followed a period of transition for the firm's top investment role. His focus on volatility and macro risks signals a potentially defensive shift in the firm's strategic outlook as it prepares for rougher seas ahead. Attempts to reach RLAM for further comment on Nicoll's remarks were not immediately successful.

Correction: An earlier version of this article misstated the month of Will Nicoll's appointment as CIO. He was appointed in December 2025, not earlier in the year.
