1. Introduction: Opportunity Begins Where the Structure Breaks

Janet Yellen is currently in a very difficult situation. She has been appearing frequently on major media outlets like CNN and CNBC, but not simply out of patriotism or concern for the economy. Shortly after stepping down as Treasury Secretary, she joined the Global Advisory Board of PIMCO, one of the world’s largest bond management firms, while at the same time, former Fed Chair Ben Bernanke was removed from the board. This personnel change is more than symbolic.

PIMCO includes former White House chiefs of staff, defense policy advisors, and other policymakers as advisors. Their activities are not merely about insight but represent a brand and information network that guides billions of dollars in capital inflow. In fact, when Bernanke joined, PIMCO saw approximately $5 billion in new capital inflow, proving that investors trust direct connections with policymakers more than forecasts.

PIMCO calls this “enhanced policy forecasting.” During the 2008 financial crisis and the 2020 COVID crisis, they read the Fed’s policy moves earlier than anyone and leveraged that insight for massive profits. In other words, it’s not insight—it’s the power of connection.

So with the U.S. Treasury market shaking due to Trump’s tariffs and short-term bond issuance policies, did PIMCO suffer losses? No. Since December 2023, PIMCO had already started reducing its allocation and leverage in U.S. long-term bonds. Marc Seidner and Pramol Dhawan disclosed in a report dated December 9, 2023, that they were reducing long-duration U.S. Treasury exposure, citing “concerns about fiscal sustainability and inflation risk from tariffs.” They anticipated the risk even before Yellen arrived.

But the real issue wasn’t long-term U.S. Treasuries. Recently, Yellen has been clashing internally with the Trump administration over short-term bond issuance policy. Despite having issued massive short-term debt herself due to near-zero Treasury balances during her tenure, she strongly opposes her successor Bessent’s renewed push for short-term issuance.

In media interviews, she made the following statements:

  1. Reviving U.S. manufacturing is unrealistic.
  2. Conflict with China has systemic implications.
  3. Long-term bond yields should be falling amid uncertainty but are rising instead.
  4. Treasury issuance should be predictable and orderly.
  5. Now is the time to reduce short-term issuance.

These views hint at discord with her successor, and she notably skipped an early-April dinner with former and current Treasury Secretaries, citing an Australian engagement. The event, hosted by former Secretary Steven Mnuchin, reportedly involved policy clashes and intense debates, rather than a ceremonial gathering.

Yellen is also highly sensitive to signs that the Trump administration might overturn the USMCA (the successor to NAFTA). This poses a major risk to the value of Mexican and Canadian bonds, which PIMCO recently increased exposure to. Mexican bonds positioned for disinflation are falling due to tariff risks, and Canadian bonds, which were bets on early rate cuts, face the same threat.

Yellen has appeared in interviews guiding the Fed, stating, “If the Fed ends up supporting Trump’s tariff policies, it would amount to endorsing his agenda,” reflecting concerns that PIMCO’s policy forecasting ability may become unreliable in such conditions.

Yellen’s behavior must thus be understood not as economic interpretation but as position defense and operation of an information network. Following that flow is the key to finding true investment timing.


When interest rates move, the market shakes. Yet most investors only see the surface: “Rates are up?” “The Fed said something?” But the real question is:

Who’s selling, who’s buying, and where is the money moving?

Without answering this, both investment and timing are illusions.

In 2025, two forces are clashing in the U.S. market: one is the structural distortion from the Trump administration’s tariffs, fiscal, and bond policies. The other is the real flow created by pre-positioning from global bond giant PIMCO. Especially now that former Treasury Secretary Janet Yellen is a PIMCO advisor, her media interviews are more than economic commentary—they are structural signals linking markets, policies, and institutions.

This report completely tracks that flow using the Hoho-style reasoning framework—”all money flows are someone’s profit or loss”—and presents the most precise entry timing strategy for long-term bond ETFs (TLT, TMF).


2. Structure-Based Entry Strategy: Why You Must Follow the 5-Stage Signal

Long-term bonds deliver strong returns when the structure reverses. Entering before the reversal invariably results in losses. Therefore, only a tracking-based approach waiting for the 5-stage structural signal is viable.

StageStructural SignalCondition
Policy signal changeDovish FOMC speech, downward dot plot, employment concerns
Market expectations priced inFF Futures rate decline priced in early, widened SOFR-FF spread
Real rate peak confirmation30Y TIPS yield declines (e.g., 2.52% → 2.3%)
Supply-demand reversalAuction BTC increases, tail narrows → strong institutional buying
Volatility stabilizesMOVE Index falls from 130 → 110, policy credibility restored

Only when all five conditions are met should you enter TLT or TMF.


3. Case Study ① – Profit After Structural Conditions Fulfilled (Nov 2023~Feb 2024)

DateEventStructural Signal Stage
2023.11.01Dovish FOMC speech① Policy change starts
2023.11.15FF Futures reflect rate cuts② Market expectation priced in
2023.12.0530Y TIPS yield drops from 2.52% to 2.40%③ Real rate peak confirmed
2023.12.2030Y Treasury auction BTC up, tail narrows④ Supply-demand reversal
2024.01.10MOVE Index plunges from 135 to 110⑤ Volatility stabilizes → Entry timing complete

📌 Buy date: Jan 10, 2024 → Sell date: Feb 8, 2024

  • TLT: $87 → $96 (+10%)
  • TMF: $46 → $60 (+30%)

▶ Only investors who entered after fulfilling all structural conditions realized this return.


4. Case Study ② – PIMCO’s Successful Preemptive Defense Strategy (Dec 2023~Mar 2024)

1) PIMCO’s Warning: December 2023

  • 📄 PIMCO Cyclical Outlook (Dec 2023): “Restoring the Balance”
  • Warned of rising long-term yields due to expanded fiscal spending → increased bond issuance
  • Formalized long-term bond reduction, urged caution on duration risk
  • 📉 PIMIX duration: drops from 6.4 to 5.1 years

2) Actual Fund Composition Change (Jan 2024 Commentary)

  • U.S. Treasuries: -9%
  • Canada & Mexico bond allocation increased
  • Reduced leverage and shortened duration

3) Market Results (Feb~Mar 2024)

  • CPI surprise (3.9%) → Rate cut expectations collapse
  • Fed credibility collapses → Market rates surge
  • 30Y Treasury yield: 4.08% → 4.55% (End of Mar 2024)

📉 Performance Results:

  • TLT: -7%, TMF: -20%+
  • PIMCO Income Fund (PIMIX): Defensive success with only -1~2%

9. Strategic Response Summary

✅ Wait Until Entry Conditions Are Met

  • All: real rate peak, MOVE stabilization, supply-demand reversal must be confirmed

✅ Example Portfolio Using ETFs While Waiting

🔚 Conclusion: Markets Move at Structural Turning Points

Interest rates, bonds, ETFs—all turn direction when structure changes. Fed statements are only a condition; the core is the actual reversal of money flows.

Prediction is risky. Track the structure.
Do not enter without context.
Waiting is strategy, and structure is the signal.
