The US Treasury's move to expand long-dated debt buybacks has been characterized by Bank of America Securities chief investment strategist Michael Hartnett as a form of "quasi-quantitative easing." In his view, this represents the latest policy lever deployed by Bessent to defend the 5% yield threshold on 30-year Treasuries, a line he likens to the Maginot Line.

According to trading desk reports, Hartnett warned in his latest Flow Show weekly that if Bessent fails to push the 30-year Treasury yield back below 5%, the dollar could face a sharp decline. In that scenario, investors would likely intensify short positions in AI hyperscalers, private credit, and other highly leveraged assets, alongside cyclical sectors such as financials. This risk is expected to persist and escalate ahead of the November midterm elections.

Bond market turbulence has already spilled over into equities. The S&P 500 has fallen 1.9% this week, threatening to snap a three-week winning streak. The 30-year Treasury yield initially retreated after the Treasury's expanded buyback announcement but later recouped most of those losses, hovering near 5.2% as of last Friday, having previously touched levels not seen in nearly two decades.

The "Bessent Put": A New Card in the Policy Toolkit

Hartnett frames the Treasury's expanded long-dated debt buybacks within what he calls a series of "Bessent puts." His framework includes dollar swap agreements with Asian and Gulf nations, foreign exchange intervention on the yen, and now this "quasi-QE" executed through doubled long-dated Treasury buybacks with the Federal Reserve's tacit approval.

Hartnett notes that this policy action comes amid multiple overlapping pressures: US public debt has just surpassed $40 trillion; net Treasury issuance for 2026 and 2027 is projected at roughly $2 trillion annually, crowding out corporate bond markets; and with nonfarm payroll growth at zero and subdued inflation data, the 30-year yield rising to two-decade highs underscores an urgent need to rebuild policy credibility.

He also cautions that fiscal "firefighting" measures require coordination from Fed chair candidate Warsh, who would need to deliver a "just-right hawkish" signal at the Jackson Hole symposium on August 28 to prevent further dollar weakness.

All Three Arrows Have Missed: Policy Credibility Continues to Erode

Hartnett uses the phrase "all three arrows have missed" to summarize the current policy predicament of the Trump administration.

He points out that the administration's three key targets—3% GDP growth, reducing the fiscal deficit to 3% of GDP, and increasing crude oil output by 3 million barrels per day—remain unfulfilled: GDP growth has stayed below 2% for the past six quarters; the fiscal deficit stands at a hefty 6% of GDP; and crude output has risen by only about 300,000 barrels per day since 2024.

In his assessment, policy credibility is ultimately tested by bond and currency markets—rising yields and a weakening currency signal that credibility is being eroded.

This explains the administration's strong determination this late summer to defend three "Maginot Lines": $4 per gallon gasoline, 160 yen per dollar, and the 5% Treasury yield. However, constraints such as the US-Iran "economic war" and US crude inventories and strategic petroleum reserves sitting at 40-to-50-year lows make it difficult to ease oil price pressures. Similarly, the effectiveness of yen intervention depends on the Bank of Japan's willingness to hike rates at its September 18 meeting.

Policy Can Cap Yields, But Not Push Them Down

Hartnett remains cautious about the effectiveness of this "quasi-QE" initiative. He explicitly states that panic-driven "repair" measures for fixed-income markets "should cap but not push down" Treasury yields.

His logic stems from the past two decades: each round of quantitative easing marked the starting point of bull markets and underpinned Wall Street's "too big to fail" narrative, with every unconventional monetary stimulus generating extraordinary asset price gains.

For this reason, a new round of QE should reasonably be expected to succeed. Yet if Bessent ultimately cannot push the 30-year yield below 5%, it would signal policy failure, triggering a sharp dollar decline and prompting asset allocation shifts toward shorting risk assets, shorting leverage (AI hyperscalers, private credit), and shorting cyclical assets (financials)—all of which could converge before the midterm elections.

Against this backdrop, Hartnett's contrarian long preferences include gold, long-duration REITs, XBI (biotech ETF), regional banks, small caps, and Hong Kong property stocks.

Fund Flows: Extreme Optimism Persists, Semiconductors Keep Bleeding

Despite escalating bond market volatility, current market sentiment remains highly exuberant.

According to BofA's EPFR data, US equity funds saw net inflows of $28.9 billion for the week ending August 19, the highest in three weeks. BofA's bull-bear indicator rose from 9.3 to 9.5, continuing to flash an "extremely bullish" signal and triggering a sell warning.

The structural divergence in fund flows deserves attention. US Treasury funds recorded weekly net inflows of $7.4 billion, the largest in six weeks. Investment-grade bond funds posted net inflows for the 20th consecutive week, reaching $7.5 billion. Emerging market bonds attracted $3.3 billion, the most in 11 weeks. Meanwhile, semiconductor ETFs have experienced net outflows for three straight weeks, with cumulative redemptions reaching $6.3 billion. Financial sector funds saw weekly outflows of $2 billion, the largest in 11 weeks.

For BofA private clients, with assets under management of $4.7 trillion, equity allocation stands at 66.5%, bonds at 16.9%, and cash at 9.4%. Over the past four weeks, private clients have consistently bought Japan-related, municipal bond, and TIPS ETFs while trimming emerging market debt, utilities, and financial sector ETFs.
