Downgrade, Quoted Spread and a Cure Period
An adviser runs a CNY 5 million bond portfolio for a corporate treasury client that must keep at least CNY 200,000 available within any three-month window. Holdings: CNY 3 million of a 5.8% coupon corporate bond rated AA with modified duration 4.2 years; CNY 1.2 million of a one-year policy-bank bond; CNY 800,000 in a money market fund yielding 1.9% (seven-day annualised). Overnight the corporate bond is cut to AA-, its credit spread widens 120 bp and the price falls 4.8% to 98.9. The client's investment policy statement requires every holding to be rated AA or better, with a 90-day cure period. The dealer now quotes 98.2 bid / 99.6 ask, against a normal 5 bp spread. The next coupon of CNY 87,000 is payable in seven weeks. The CFO wants to "sell everything now and wait"; the adviser notes the issuer's operating cash flow still covers interest 3.1 times.
1. Test the 4.8% price fall against duration, and interpret the dealer's 98.2/99.6 quote.

Duration check. For a spread-driven move, approximate price change ≈ −D × Δspread = −4.2 × 1.20% = −5.04%. The realised fall is −4.8%, a difference of 0.24 percentage points, explained by positive convexity and accrued coupon. The observed price is therefore consistent with a genuine credit repricing, not a stale or erroneous quote - the move is real and should be treated as information, not noise.
Quote interpretation. Mid is (98.2 + 99.6)/2 = 98.9, matching the last price. The round-trip spread is 1.4 points, about 140 bp, against a normal 5 bp - roughly 28 times normal. On the full CNY 3 million position, crossing the spread costs about CNY 42,000 (1.4%), and the bid of 98.2 already embeds a further discount to par. Dealers widen like this when they do not want inventory, which means liquidity, not only credit, has deteriorated. Selling the entire position in one ticket transfers that entire cost to the client.
Implication: the mark-down is roughly what the duration model predicts for the credit event, but the exit cost is a separate, negotiable loss that the adviser controls through execution method.
2. Reconcile the IPS breach with the client's cash needs and recommend an action sequence.

The two constraints point in different directions; solve the cash need first so the credit decision is not driven by panic.
Cash need. The client needs CNY 200,000 within three months. Available without touching the downgraded bond: CNY 800,000 in the MMF, plus the CNY 87,000 coupon in seven weeks. There is no forced sale. Selling everything to meet a CNY 200,000 need would crystallise a CNY 42,000 spread cost for no reason.
IPS breach. The bond is now below the AA floor. The cure period is 90 days, so the obligation is to exit within the window, not within the hour. The 3.1× interest coverage is relevant to how you exit, not whether - a covenant is a covenant, and the adviser cannot hold on a personal view if the IPS is not amended (amending it mid-breach requires the client's documented, informed consent and would itself need scrutiny).
Sequence: (1) fund near-term needs from the MMF; (2) obtain at least three dealer quotes and sell the bond in two tranches inside the cure window to avoid dumping into a wide market; (3) confirm the trade and the IPS cure in writing to the client; (4) if no executable market exists, document the attempts and escalate to the client for a written decision.
Do not promise the CFO that "waiting" is free - carry cost is the yield forgone on the MMF swap.
3. What should the adviser monitor and document over the cure period, and what would change the recommendation?
Read the worked answer
Monitor, with a defined frequency:
- Spread trajectory versus the AA- peer curve - is the 120 bp widening idiosyncratic or sector-wide?
- Issuer disclosures, rating watch status, refinancing calendar and the next earnings date relative to the 90-day window.
- Dealer quotes from at least three counterparties each week, to detect whether liquidity is normalising (spread compressing toward the 5 bp norm) or freezing.
- The MMF's own yield and liquidity, since it is the liquidity backstop.
Document: the IPS clause, the downgrade notice and date the cure clock started, each quote obtained, the rationale for tranching rather than immediate sale, and the client's acknowledgement.
What would change the recommendation:
- A second notch down, or a missed coupon, converts this to a distress situation - sell at the bid, prioritising certainty over the 140 bp.
- A spread re-tightening toward 60–70 bp would let the exit be executed at materially lower cost, so tranching order matters.
- A client instruction to amend the IPS floor - only with written, informed consent, and only if the adviser independently judges the credit sound.
- A call on the policy-bank bond or an unexpected cash demand would eliminate the flexibility and force an immediate exit.
