Same-day liquidity: what treasurers actually need from money market funds | Insight Investment

Liquidity is about timing, not just allocation

For most treasury functions, we believe liquidity is no longer just about where cash is invested. It is about when it can be accessed, how reliably it arrives, and how it fits within daily operational constraints. Payment cycles, margin calls and internal funding needs increasingly require access to cash within the same day, placing greater emphasis on the practical delivery of liquidity rather than headline liquidity classifications alone.

From concept to delivery: what same-day liquidity looks like

In this context, same-day liquidity needs to be understood in operational terms. Liquidity that is available in theory but constrained by cut-off times, dealing windows or settlement delays may not meet the needs of a treasury function managing intraday cash flows. Funds designed to deliver same-day access illustrate how this can be implemented in practice, with defined dealing cut-offs and settlement processes that aim to provide predictable access to cash when it is required.

At a practical level, three factors determine whether a fund can support intraday liquidity needs.

1. Cut-off times define when instructions must be submitted to achieve same-day settlement. These cut-offs are often earlier than treasurers expect and may not align with internal payment cycles. Missing a dealing deadline can push liquidity availability into the following day, creating a mismatch between expected and actual cash access.
   
   
2. Settlement processes matter just as much. Same-day dealing does not always equate to immediate cash availability. Treasurers need clarity on when proceeds are credited and whether they can be deployed for payments within the same operational window. Certainty of timing is often more important than marginal differences in yield.
   
   
3. Operational integration is the third constraint. Treasury management systems, bank connectivity and internal workflows need to reflect the actual timing of cash movements. Without this alignment, there is a risk of overestimating available liquidity.

These factors shape how treasurers should think about intraday liquidity. It is not sufficient to treat same-day funds as interchangeable with overnight cash. Instead, they should be viewed as part of a broader liquidity framework, sitting between immediate bank balances and longer-dated investments. Their role is to provide reliable, same-day access within defined parameters.

The gap between when liquidity is expected and when it is actually available has direct implications for treasury operations. Liquidity buffers need to be structured with greater precision. Core intraday requirements, such as payment run coverage and contingent outflows, should be held in instruments that provide immediate or highly predictable access. Same-day MMFs can complement this by providing scalable liquidity, but only where cut-offs and settlement timelines are fully understood and incorporated into planning.

Systems and processes may also need to be adjusted. Cash visibility should reflect actual availability rather than assumed liquidity. Sweep structures and investment policies should be tested against real dealing timelines to ensure they perform as expected under both normal and stressed conditions.

From a policy perspective, treasurers should revisit how liquidity tiers are defined. Traditional distinctions between operational and strategic cash may not fully capture intraday requirements. A more granular approach, distinguishing between immediate, same-day and short-term liquidity, can lead to more effective allocation and reduce the risk of shortfalls.

In practical terms, treasurers should focus on aligning investment cut-offs with payment schedules, validating settlement timing across counterparties, and stress testing whether liquidity remains accessible under tighter market conditions or operational disruption. Diversifying liquidity sources across banks and funds can also improve resilience.

How Insight supports treasury teams

Insight is working with treasury teams to address these challenges through targeted policy reviews, intraday liquidity mapping and scenario analysis. This includes assessing how existing MMF allocations perform against real operational requirements and helping design liquidity frameworks that balance access, certainty and efficiency.

We are working with treasurers to review liquidity policies, align investment frameworks with intraday cash flow requirements, and validate that liquidity remains accessible when it is needed most.
