Over the last years, relating to the cash market funds construction, redemption capability is non-linear in preliminary weekly liquid belongings (WLA), and the timing of outflows issues independently of their dimension.
Within the frozen-market baseline (no asset gross sales), redemption capability will increase monotonically with preliminary WLA and with the size of the stress horizon—although this monotonicity holds on common: a fund with 35% WLA composed completely of short-dated devices can, in some configurations, show extra resilient than one with 40% WLA that exhausts its 17.5% government-asset allowance.
Extra importantly, the connection is strongly formed by the point profile of redemptions. Entrance-loaded outflows materially scale back capability, significantly for funds near the regulatory minimal, whereas extra gradual (unimodal) redemptions are much less destabilising for a given cumulative shock.
This highlights a central contribution of the framework: assessing Cash market funds (MMF) resilience requires modelling not solely shock dimension but in addition the time profile of redemptions.
The stabilising function of WLA is determined by whether or not WLA belongings stay liquid in durations of stress.
Once I permit funds to promote authorities belongings, the redemption-capacity frontier shifts favourably outward relative to the frozen-market benchmark, particularly for funds in low WLA buckets and for front-loaded redemption patterns.
Nonetheless, when market circumstances are tight, and solely a part of these authorities holdings will be bought, the advance, because of WLA will increase, is way smaller, and outcomes turn into extra uneven throughout redemption profiles (some outflow patterns
turn into far more durable to face up to than others). These outcomes spotlight a key particular function: a better measured WLA buffer improves resilience most reliably when it’s achieved by means of money flows which can be generated beneath stress.
