Fund liquidity stress testing, one fund from the overnight run to the signed pack
Quillfield Capital tests 90 open-ended funds, about $412 billion, every quarter. On Tuesday, October 20, 2026, the Q3 results are in and approvals are due on Friday, October 30. Here is one fund, Quillfield Global Strategic Bond Fund, a $4,819.3 million UCITS sub-fund in Ireland, screen by screen in the working solution.
- 01Tuesday morning
The agents ran the quarter overnight, and tell her what they did
Amara Nwosu · Head of Liquidity RiskAmara's Today screen shows 90 of 90 funds tested in 1,452 runs, 3 breaching under stress (Global Strategic Bond, EM Local Debt and European Real Estate Income), 9 on watch and 61 of 90 signed off. Under "Needs you", six items in order. Beside them, each agent explains its night in its own words with its sources, and she can ask them anything about the cycle.
Checker agent, 3:02 a.m.: “I challenged the first pass for Global Strategic Bond: it kept gilts highly liquid… Highly liquid assets now run out on day 4, not day 5.”

A scenario built from the fund's own holders
Scenario agentThe Scenario agent read the transfer agent's register and weekly flows since 2011. The top three holders own 23.6%, and Northbrook Pension Scheme redeemed 38% of its holding in four days in October 2022. It proposed S-07, "Top 3 holders exit plus a gilt shock": the three leave over 5 dealing days, other holders redeem 1.2% of NAV a day (the 99th percentile), gilt yields rise 150 bp over 3 days and gilt bid-ask widens four times. Its five days add up to 30.2% of NAV, against a worst week since 2011 of 10.2%.
“Results under S-07 stay provisional until a risk manager approves it.”
- 03Before it counts
She approves the scenario, with a reason
Amara Nwosu · Head of Liquidity RiskOn approval, results on 90 funds stop being provisional: under S-07, 1 breach, Global Strategic Bond, and 5 on watch. The reason is required and goes in the audit trail. She picks "Plausible and severe: grounded in the register and 2022 history" and signs as herself. Signed in as the analyst, Daniel would find the button locked.
“Reason (required, kept in the audit trail)”
- 04The drain-down
The fund drawn as a tank, draining day by day
Liquidation and Liability agentsThe fund's liquidity tiers drain from the top as redemptions and margin calls are paid. Requests run 3.2%, 4.1%, 5.6%, 6.9% and 10.4% of NAV on days 1 to 5. Variation margin takes 2.9%, 2.4% and 1.2% on days 1 to 3. The fund falls below the 5% liquidity floor on day 3, and on day 4 its highly liquid assets are gone: $241M (5.0% of NAV) is sold from investment-grade credit at a stressed cost. On day 5, requests of 10.4% pass the 10% gate in the prospectus (§7.4, p. 47), and $19M is deferred to day 6. The view opens in waterfall order, with a switch to the policy's pro-rata slice.
The breach day is circled on the tank. A day scrubber moves the water line from D0 to D10.
- 05Days to liquidate
The agents check each other, and the sale order
Checker agentAcross 412 positions, the whole fund takes 4.3 days to liquidate in normal markets and 11.6 days under stress, at a cost of 0.31% rising to 1.74%. 37 positions are flagged as priced on proxy data. The Checker agent compares both sale orders. Under the policy's pro-rata slice, the breach day stays day 4 and holders who stay keep 21% of what remains in highly liquid assets. A waterfall keeps exit costs at 0.94% but leaves them none.
The Checker agent never settles a disagreement itself. Below 85% confidence, a person decides.
- 06A challenge
“Can we sell gilts faster?” — answered from the data
Tobias Lind · Portfolio Manager, Global Strategic BondTobias thinks he can sell gilts in a day, even in 2022. Amara puts his question to the agents beside the tank. The Liquidation agent answers at 88% confidence. In October 2022 sterling gilt volumes held up, but bid-ask on long gilts widened four times. Selling the 2049 and 2051 gilts in one day at 20% of volume would cost about 1.9% on those lines, and even at 40% of volume the breach only moves to day 5. Tobias can read and comment on his funds, but he cannot approve them.
“I kept them in moderately liquid; the risk manager decides.”

A stressed swing factor, with the arithmetic shown
Liquidity Tools agentThe fund uses two liquidity management tools: swing pricing as its anti-dilution tool and a 10% redemption gate. The Liquidity Tools agent adds up the stressed costs: a dealing spread of 1.12%, market impact of 0.56% at 20% of volume, and 0.06% of duties and fees, 1.74% in all. It rounds up to 1.80%, inside the supplement's 2.00% maximum (p. 14). Over days 1 to 5 the fund pays out $1,436M. At today's 0.45% factor, holders who stay would bear about $19.4M of dealing costs.
Maker-checker: Daniel Reyes prepared it at 8:05 a.m.; a different person must approve it before it goes to the fund administrator.
- 08Three rulebooks
One strategy under UCITS, Rule 22e-4 and AIFMD, side by side
Checker agentThe same scenario runs on the three funds that share the strategy. The UCITS breaches: highly liquid assets are exhausted on day 4, and the Central Bank of Ireland must be told of a material liquidity risk. Strategic Income Fund, a US mutual fund, dips below its 25% highly liquid minimum on days 3 to 5 (low 18.6%). That means a board report at the next meeting but no Form N-RN, because the shortfall lasts 3 days, under 7. Strategic Credit Fund, a Luxembourg AIF with 30 days' notice, passes. Every cell cites its rule and the fund document.

A 64-page Risk Committee pack, every figure traced
Pack agent, then Daniel, Amara and HelenThe Pack agent drafted the Q3 Risk Committee pack for November 4: 64 pages in ten sections, 214 figures each linked to its run. Daniel Reyes prepared it. Amara reviews it once the three breach conclusions are approved, and Helen Marsh, Chief Risk Officer, signs it. The notice to the Central Bank of Ireland follows the same pattern: the Pack agent drafts it, Ravi Iyer in compliance prepares it and Helen approves it.
“Prepared, reviewed and signed by three different people”

Sofia Brandt · Internal AuditThe audit trail lists every agent step with its version, every approval with its reason and every override with its evidence. That includes Amara's approval of S-07, the swing factor calculation and Mei Lin Tan's requested override of Pampas Agro 2031, from 31 stressed days to 24 after a dealer bid. It is kept for 7 years. One click exports the evidence pack for an auditor or the regulator, and the export is itself logged.
