Tuttle's Newton Makes the Case for an All-Weather Portfolio

Frances Newton, chief investment officer of Tuttle Capital Management, told Bloomberg's 'ETF IQ' that investors need an 'all-weather' portfolio, in a discussion with hosts Scarlet Fu and Eric Balchunas of a report that the US Treasury could draw down part of its cash pile to buy back higher-yielding older securities and curb rising borrowing costs.

The idea that the US Treasury might spend down part of its cash balance to retire older, higher-coupon debt has moved from a technical footnote to a live portfolio question. On Bloomberg's ETF IQ, Frances Newton, chief investment officer of Tuttle Capital Management, joined hosts Scarlet Fu and Eric Balchunas to talk through a report that the Treasury could do exactly that in an effort to tackle rising borrowing costs. Her framing was blunt: this is an environment for an "all-weather" portfolio rather than a single directional bet.

The discussion, carried by Bloomberg Markets, lands at a moment when the cost of financing the federal government has become the dominant variable for almost every other asset class. Equities were mixed as the conversation aired. As of the last trade at 19:58 GMT on Monday, 24 August 2026, the S&P 500 tracker (NYSEARCA: SPY) was at $763.80, down 0.25% from a prior close of $765.72. The Nasdaq 100 fund (NASDAQ: QQQ) was weaker at $706.68, off 0.95%, while the Dow 30 vehicle (NYSEARCA: DIA) bucked the tape at $533.91, up 0.32%.

What a cash-funded buyback would actually do

A Treasury buyback is straightforward in mechanics and subtle in effect. The government uses cash on hand to repurchase bonds already in circulation rather than waiting for them to mature. Targeting higher-yielding older securities means going after the coupons issued when rates were elevated — the paper that costs the taxpayer the most in interest each year.

Funding those repurchases out of the Treasury's existing cash pile, rather than out of new issuance, is the detail that matters to markets. If the buybacks were financed by selling fresh bonds, the exercise would be closer to a maturity swap: supply removed at one point on the curve, supply added somewhere else. Drawing on cash instead removes securities from the market without immediately replacing them, which drains net supply and, at the margin, pushes prices up and yields down on the affected issues.

Two second-order effects follow. The first is liquidity: a Treasury cash balance that shrinks is cash returning to the private sector, a loosening impulse in the plumbing of the money markets. The second is duration: which maturities get bought determines whether relief shows up at the front end, the belly, or the long bond. An investor positioned for a steepener and a flattener arrives will not be saved by having called the policy correctly.

Why 'all-weather' is the natural answer to policy uncertainty

The all-weather concept is an old one in asset management — build a mix that does not depend on one macro outcome, and accept a lower ceiling in exchange for a higher floor. The classic construction spreads risk across growth-sensitive assets, duration, inflation hedges and cash-like instruments so that no single regime shift can dominate the result.

The argument for it right now rests on the sheer breadth of plausible outcomes around debt management. A cash-funded buyback programme could compress yields and rescue long-duration equities. It could equally be read as a signal that the Treasury is uncomfortable with the market's absorption capacity, which would be a warning rather than a comfort. Yields could fall on the announcement and back up when the cash balance has to be rebuilt through heavier bill issuance. All three paths are consistent with the same headline.

Monday's tape shows what regime disagreement looks like in practice. A large-cap benchmark down a quarter of a percent, a tech-heavy index down close to a full percent, and a blue-chip industrial index up a third of a percent is not a market moving as one. It is a market rotating, and rotation is precisely the condition an all-weather allocation is designed to survive rather than to time.

The building blocks investors reach for

An all-weather sleeve in ETF form typically leans on a handful of exposures, each doing a distinct job:

• Broad equity beta — the growth engine, and the piece that suffers most in a rate shock.
• Intermediate and long Treasuries — the duration ballast that gains if buybacks succeed in pulling yields lower.
• Inflation-linked bonds — protection against the possibility that easier financial conditions feed back into prices.
• Real assets and gold — hedges against a loss of confidence in fiscal management, the tail risk that debt-management engineering is meant to head off.
• Short-dated bills and cash — the optionality to buy anything that dislocates, and the one holding whose yield falls fastest if the front end rallies.

Weighting is where the judgment lives. An all-weather portfolio built for a world in which the Treasury is actively suppressing borrowing costs looks different from one built for a world where it is running out of room to do so. Newton's point on the programme was directional rather than prescriptive: own something for each state of the world.

What to watch from here

Three things will decide whether the buyback discussion becomes a market event or stays a talking point. First, confirmation — whether the Treasury formally commits to funding repurchases from cash and, if so, at what scale. Second, the maturity profile of any operations, which determines the shape of the curve response. Third, how the cash balance is rebuilt afterwards, because that refinancing is where the relief can quietly be handed back.

For ETF investors the practical read is narrower than the macro debate. If yields on longer paper drift lower, duration funds and the rate-sensitive corners of the equity market are the direct beneficiaries. If the market reads the exercise as a sign of strain in absorbing supply, gold and short-duration holdings do the work instead. Constructing for both, rather than picking, is the whole argument Newton put on the table.

None of this changes the arithmetic of federal interest expense on its own. Buying back expensive coupons lowers the running cost of the existing stock of debt; it does not shrink the stock. That distinction is why the all-weather framing keeps resurfacing: debt management can smooth the path of borrowing costs, but it cannot decide the destination.

Frequently asked questions

What did Frances Newton say on ETF IQ?

Frances Newton, chief investment officer of Tuttle Capital Management, argued that investors need an 'all-weather' portfolio. She appeared with hosts Scarlet Fu and Eric Balchunas on Bloomberg's ETF IQ, where the discussion centred on a report that the US Treasury could draw down some of its cash pile to fund buybacks of higher-yielding older securities.

What is a Treasury buyback?

A Treasury buyback is when the US government repurchases bonds that are already trading in the market rather than waiting for them to mature. Targeting higher-yielding older securities focuses on debt issued when interest rates were elevated, which carries the largest annual interest cost for the government.

Why does funding buybacks from cash matter?

If repurchases are paid for out of the Treasury's existing cash balance rather than through fresh bond sales, securities are removed from the market without immediately being replaced. That reduces net supply, which tends to support prices and pull yields lower, and it also returns cash to the private sector.

What is an all-weather portfolio?

An all-weather portfolio is an allocation designed to hold up across different economic regimes rather than betting on one outcome. It typically spreads risk across equities, government bonds, inflation-linked debt, real assets such as gold, and short-dated cash instruments, accepting a lower ceiling in return for a higher floor.

How did major index ETFs trade during the discussion?

As of the last trade at 19:58 GMT on 24 August 2026, the S&P 500 tracker SPY was at $763.80, down 0.25%. The Nasdaq 100 fund QQQ was at $706.68, down 0.95%. The Dow 30 vehicle DIA rose 0.32% to $533.91, a split tape showing rotation rather than a uniform move.

Would buybacks reduce the national debt?

No. Repurchasing higher-coupon bonds lowers the running interest cost on the existing stock of debt, but it does not reduce the amount outstanding. The Treasury still has to rebuild any cash it spends, typically through further issuance, which is where some of the initial relief can be given back.
