Designing Liquidity Portfolios for Stability and Resilience

Main article image

Institutional investors leverage liquidity portfolios in a variety of ways across their business and investment operations. Despite differences in how various investors commit to liquidity strategies, they are all typically seeking to create stability in their portfolios.

Adequate liquidity can enhance operational planning, create a ready source of funding for expenses and commitments and help reduce volatility across various asset pools. Yet, liquidity portfolios can present investors with a conundrum.

Some investors lose sight of the value of liquidity when volatility is low, markets are stable and there is a clear line of sight towards sustained economic growth. The conundrum becomes apparent during times of market disruption when exogenous events create volatility and cause liquidity to dissipate.

When unexpected expenses arise or access to capital is constrained, organizations may face added strain as they work to sustain their missions. Prioritizing liquidity can help preserve access to funds and support more confident, informed investment decision-making.

  • Operational cash is cash needed for day-to-day activities and, in many cases, requires near same-day liquidity. A separately managed account (SMA) is not typically an ideal solution for operating cash pools unless cash needs are infrequent and highly predictable. In this space, bank deposit products and/or money market funds can be most valuable to investors.
  • Reserve and Strategic cash allocations can introduce modest interest rate and credit exposure in pursuit of higher yields and total return, while maintaining alignment with investor objectives and investment policy statement requirements centered on capital preservation.

A Client-Centered Approach to Liquidity

Each client's liquidity needs are shaped by their unique objectives, operating demands and risk considerations. A solutions‑based approach through SMAs can allow portfolios to be structured around those needs—balancing total return goals with appropriate attention to risk, liquidity and policy constraints.

Key Features of Separately Managed Accounts

  • Ability to tailor to specific objectives: Align with the potential timing of cash flows and strategically position the portfolio on the yield curve
  • Potential tax advantages: Control gain/loss recognition
  • Direct ownership: Direct ownership of securities rather than being commingled with other investors in a larger pool
  • Diversification: Across security types, sectors, sub-sectors and individual issuers

Through tailored portfolio construction, clients can align operating, reserve and strategic cash pools with their broader investment objectives, while ensuring portfolios remain disciplined, scalable and adaptable as organizational circumstances and market conditions evolve. A consultative process between an organization and the investment manager can help clarify cash allocation priorities and supports thoughtful investment policy design that reflects each client's unique requirements.
