Liquidity as strategy – the evolving role of money market funds | Insight Investment

Chris Brown, Head of Money Markets, explains why volatile markets, shifting rate expectations and more resilient market structures are reinforcing the role of money market funds and short-duration strategies as a deliberate, strategic tool for preserving capital and maintaining liquidity.

What are current market conditions telling us about the role of liquidity?

Current conditions reinforce how much the role of liquidity has evolved in institutional portfolios. Despite geopolitical tensions and elevated volatility, money markets remain benign, with supply healthy and no signs of stress. This stands in contrast to previous market episodes, when liquidity could deteriorate quickly. The greater resilience seen today reflects regulatory changes introduced after the financial crisis, alongside a more conservative approach to liquidity management across the market.

Why are money market funds attracting renewed attention?

The broader investment environment has shifted in ways that are supportive of money market funds. Traditional safe-haven assets such as government bonds are now showing higher levels of volatility, with even high-quality issuers trading across wider yield ranges. At the same time, the interest rate backdrop has improved. After years of negative yields, positive short-term rates are now supporting returns in money market funds, making them more competitive relative to bank deposits. Together, these factors are increasing their appeal as a source of daily liquidity and capital stability.

How is interest rate uncertainty shaping investor behaviour?

Interest rate expectations are changing quickly, sometimes within a matter of weeks. In the UK, for example, expectations have shifted from rate cuts to the possibility of modest rate increases in the next 12 months. This uncertainty is encouraging a more flexible approach to positioning along the yield curve. In practice, this is translating into greater use of short-duration instruments, which help limit interest rate sensitivity while allowing investors to benefit from higher short-term yields. Notably, this shift has been measured rather than reactive, with overall assets under management in money market funds remaining relatively stable.

What does this mean for portfolio construction and liquidity management?

The key challenge for investors remains the need to prepare for unexpected events. Market shocks, whether geopolitical or macroeconomic, rarely provide advance warning, making it essential to maintain sufficient liquidity at all times. Within money market strategies, this is reflected in holding liquidity buffers well above regulatory minimums and avoiding reliance on secondary market liquidity. In this context, money market funds are not positioned as return-maximising tools, but as instruments focused on capital preservation and flexibility. Their role within portfolios is becoming more strategic, forming an active part of asset allocation rather than serving as a temporary or residual holding.
