The 77.5% Second Cut: Warsh’s October Hike Countdown — A Duration-Risk Playbook for MPF Bond Funds

Track 2 Trading Desk | 26 September 2026

Eight days after the Federal Reserve raised rates by 25 basis points on 16 September, the market has already moved on. The question is no longer whether there will be another hike, but how big the October one will be. CME FedWatch put the probability of a further 25bp increase at the 28 October meeting at 77.5% on 24 September — up from 53% the day before. This is not noise: New York Fed President John Williams said the same day that another hike before year-end was a “reasonable” expectation, and Goldman Sachs has pivoted 180 degrees from “September then pause” to calling for an October move. For MPF members, the federal funds rate itself was never the point. What it is repricing — your bond holdings — is.

The Macro Matrix: A Global Hiking Relay, Risk-Off for Duration

Four quadrants, one direction.

Policy: the hiking relay has spread from Washington to Scandinavia. Norges Bank raised its policy rate 25bp to 4.50% on 24 September — its second hike this year, following one in May — with Governor Ida Wolden Bache stating the committee is “prepared to raise them again.” Sweden’s Riksbank held at 1.75% the same day but Governor Erik Thedeen signalled a hike before year-end is now likely. The ECB and the Bank of Japan had already tightened earlier in September. Five major central banks moving in a single month share one culprit: war-driven energy prices — Brent crude settled at US$105.69 on 24 September, having touched US$107 intraday.

Yields: the bond market is already pricing the second cut. The US 10-year Treasury touched 5.19% on 25 September, its highest since July 2007; the 30-year hit 5.50%, its highest since June 2004; the 2-year reached 4.908%. Between 31 August and 23 September, the 10-year climbed from 4.75% to 5.11% — 36 basis points in three weeks. A US$44 billion auction of 7-year notes cleared at 5.085%, the highest since April 1993; a US$70 billion 5-year auction cleared at 5.033% with a bid-to-cover ratio of just 2.21 — buyers are demanding ever-higher compensation for duration risk. Fed Chair Kevin Warsh has called the 10-year “the most important asset anywhere in the world,” and it is currently reminding everyone, at a 19-year high, that the easy-money era is over.

The dot plot: the doves have vanished. Sixteen of 18 FOMC officials now project at least one more hike this year; the median end-2026 rate of 4.1% implies exactly one more; officials do not expect inflation back at 2% until 2029; and the median neutral-rate estimate rose from 3.06% to 3.25% — the bar for “restrictive” itself has been raised. Williams also declared the era of explicit forward guidance “over.” Evercore ISI’s verdict: “the disappearance of the doves.”

Data: the economy is giving the Fed no reason to stop. September’s flash services PMI hit 58.7, the strongest in nearly five years; manufacturing hit 56.7, a four-year high; jobless claims keep ticking down; August core inflation of 2.4% was the lowest since March 2021, yet inflation has now run above target for five and a half years. Philadelphia Fed President Anna Paulson said outright that further tightening “may be warranted.”

Matrix conclusion: Risk-On for equities (MPF Ratings: US equities were MPF’s best-performing asset class in September), Risk-Off for duration. A bear-steepening curve (2-year at 4.9% versus 30-year at 5.5%), liquidity being drained by heavy sovereign auctions, and a technical breakout to 19-year highs. With the HKMA base rate already at 4.25% under the peg, Hong Kong bonds have nowhere to hide either.

Backtest and Win Rate: What the Last Hiking Cycle Did to MPF Bond Funds

Bond-fund losses in a hiking cycle are not theory — MPF members have paid tuition for this lesson before. Three data points.

First: the MassMutual Global Bond Fund (July 2026 fact sheet, 39% US exposure). Full-year 2022 return: -13.57%. Five-year annualised: -1.76%. Ten-year annualised: -0.75% — a decade of holding, losing money on average every year. It bounced 4.35% in 2023, fell 3.88% in 2024, recovered 7.14% in 2025, and managed 1.52% in the first five months of 2026. That is the true shape of long-duration bonds through a rate-regime change: one hiking cycle wipes out years of coupons.

Second: Manulife’s Hong Kong Bond Fund fell -9.46% in 2022 — its worst year on record — and needed until 2025 (+6.66%) to repair the damage; HSBC’s Age 65 Plus Fund (roughly 80% bonds) lost -13.21% in 2022. The 2022 lesson: when hikes arrive, “low-risk” bond allocations can fall as far as equities — just more quietly.

Third: the duration maths. Fidelity’s Hong Kong Bond Fund runs about 3.8 years of duration — the rough rule being that every 100bp rise in yields knocks roughly 3.8% off the price. In the three weeks after the 16 September hike, the 10-year rose 44bp (4.75% to 5.19%): a 3.8-year-duration portfolio has taken roughly 1.7% of paper losses from the yield move alone. Manulife’s daily prices on 22 September confirm the bleed: its Hong Kong Bond Fund -0.11%, its International Bond Fund -0.11% to -0.07%, on a day every one of its equity funds closed positive.

Lipper’s August verdict was blunt: “investors continue to favour equity risk over duration risk.” Money-market categories managed only 0.2–0.4% in August — but at least they carry no duration. In a hiking cycle, “boring” is itself a form of outperformance.

Win-rate assessment: a 16-of-18 dot plot, 77.5% on CME, five central banks tightening in concert, yields at 19-year highs — four signals, one direction. Treating long-duration bonds as a safe haven remains the most expensive assumption in an MPF portfolio, and the data of the past three months has repeatedly falsified it. DIS members should pay special attention to the structural trap in the next section.

The Switching Blueprint: Trading Duration Risk for Time

This is not market-timing advice — day-trading is structurally unprofitable inside MPF’s T+1/T+2 forward-pricing mechanism. It is allocation discipline for a regime change. Find your bond exposure below:

Scenario 1: Aged 50–64, inside DIS auto-derisking. The most dangerous group. The statutory derisking schedule shifts roughly 6.7 percentage points per year from the Core Accumulation Fund (about 60% higher-risk assets) into the Age 65 Plus Fund (about 80% bonds) starting at age 50. In other words, the system is mechanically pushing you into the asset being repriced downward — HSBC’s Age 65 Plus Fund at -13.21% in 2022 is the precedent. Blueprint: do not opt out of DIS (the 0.85% fee cap remains among the cheapest in the market), but redirect the portion you control yourself: cut long-duration global bond fund allocations from, say, 40% to 20%, moving the freed 20 points into an MPF Conservative Fund or money-market fund. The Conservative Fund’s prescribed savings rate is a near-zero 0.001% a month — but its duration risk is also zero. When yields rise 44bp in a month, “zero” beats “-1.7%.”

Scenario 2: Aged 35–50, holding bond funds as a “diversifier.” Check whether your bond fund is short or long duration. Global bond funds (39% US, typically 6–8 years duration) are high-risk in this regime; Hong Kong bond funds (3–4 years) are medium-risk. Blueprint: halve the global bond fund allocation and redirect into the Core Accumulation Fund or a North American equity fund — not because equities are “safe,” but because in a hiking regime, earnings growth can at least offset valuation compression, while a long bond’s coupon mathematically cannot offset its price fall. Keep 10–15% in short-duration bonds as rebalancing ammunition.

Scenario 3: Already heavy in conservative funds or cash. You are accidentally on the right side. Do not chase long bonds now because “yields look attractive” at 5.19% — that yield is the result of the price fall, not a buy signal. Wait until the October meeting is behind us and the dot-plot path is clear before reassessing.

Common discipline across all three: move the allocation, never the rhythm. Keep monthly contributions running, execute switches in batches, and never move more than a third of the portfolio in a single instruction.

Forward-Pricing Protection: The 28 October Timeline

The FOMC meets on 28 October, with the decision due at around 2 a.m. Hong Kong time on 29 October. MPF fund switching uses forward (unknown-price) pricing: an instruction placed on decision day is executed at a price determined T+1 or even T+2 later — you place the bet before knowing the outcome, then settle at the after-the-fact price.

Execution checklist:

1. Finish any switching by Friday 23 October. Leave at least two working days of buffer clear of meeting-week volatility.
2. No large switching instructions on 27–29 October. Bond-market volatility peaks around the decision; under forward pricing you would be trading blind.
3. Batch it. Split the amount into two or three tranches a week apart to dilute the luck component of any single unknown price.
4. After the decision, watch two things before setting next quarter’s stance: whether the December dot plot shifts up again (the median already implies one more hike this year), and whether the 10-year stabilises — a sustained break above 5.5% means duration risk gets downgraded another notch.

77.5% is not 100%. But when 16 policymakers, five central banks and a 19-year-high yield curve all point the same way, the costliest assumption in an MPF portfolio is that “bonds are safe.” Before 28 October, replace that assumption — trade duration risk for time, not principal for a lesson in the dot plot.
