Level does not matter

"The yield on the 10-year U.S. Treasury note surged to 5.34%, hitting a 24-year high. The market is consumed by a single question: Are we heading to 6%? Or 7%? Yet, bond experts offer an unexpected answer: the absolute level doesn't matter. What's truly terrifying is the 'speed'. The jump from 5% to 5.3% took significantly less time than the move from 4% to 5%. The moment this velocity accelerates further, the market will collapse without time to adapt. September employment figures plunged to shock levels, yet stocks are hitting all-time highs while yields continue to climb. Where lies the hidden, unacknowledged danger that the market is refusing to show?"

"Whether it is 6% or 7% does not matter; the real danger in interest rates is not the 'level,' but the 'speed'"

The absolute level of interest rates (whether 4%, 5%, 6%, or 7%) is less important than how fast they get there . When interest rates rise slowly, markets have time to adapt . However, if rates surge rapidly (e.g., jumping from 5% to 6% in a very short timeframe), it leaves businesses and households no time to adjust, triggering severe systemic stress . Prolonged high interest rates combined with high speed pose the ultimate danger .

The decoupling of rising stock prices and surging interest rates, and why the market doesn’t break despite an employment shock

Traditionally, higher interest rates increase borrowing costs for corporations and mortgage costs for consumers, which should suppress consumption and investment . Even though recent employment reports (such as non-farm payrolls coming in significantly below expectations) point to economic fatigue, stock markets continue to rise .

The Reason

Unlike past business cycles driven by traditional manufacturing or consumer sectors, today’s market is propelled by long-term structural themes like AI and physical AI . Investors believe that companies in these sectors can generate returns and growth rates high enough to surpass the high cost of capital, creating a decoupling between bond yields and stock performance .

"Now interest rates are set by the Treasury, not the Fed": A world shifted from QE (Quantitative Easing) to QT (Quantitative Tightening)

In the past era of low inflation and aggressive central bank intervention (Quantitative Easing), the Fed heavily bought government bonds, causing 10-year Treasury yields to move closely with Fed policy rates .

The Shift

In the post-QE/QT era, the Fed has stepped back, transferring the primary driver of bond pricing to the Treasury Department (the issuer) . Because the Treasury must issue massive amounts of debt to cover fiscal deficits regardless of central bank policy, Treasury issuance behavior and government financing needs now dictate bond yields, causing yields to rise even when policy rates are cut .

3 structural reasons why government bond yields refuse to fall: Inflation, Supply, and Rollover

Inflation

Structural inflation pressures remain stubborn due to massive capital expenditure (CapEx) into physical AI infrastructure (building robots, GPUs, data centers, and power grids) prior to productivity gains, alongside ongoing geopolitical conflicts keeping oil prices sticky .

Supply

Persistent trillion-dollar fiscal deficits and government spending (driven by defense and tech hegemony competition) require massive and continuous bond issuance .

Rollover & Yield Environment: High interest rates are expected to stay longer than anticipated, pushing up government interest expenditures and forcing continuous high-cost debt refinancing .

Hidden detonators shaking interest rates: The unwinding of Japan’s Yen carry trade and the emergence of "Bond Vigilantes"

Yen Carry Trade Unwinding

As Japanese government bond yields rise from near-zero/negative territory toward 3%, Japan's role as a global low-cost funding source is breaking down . Japanese investors are facing higher domestic borrowing costs, creating repatriation pressure to pull funds back from global assets (like US Treasuries) to pay off debts, putting secondary upward pressure on global yields .

Bond Vigilantes

With central banks and foreign central banks (like China, Japan, and the UK) scaling back or holding steady on US Treasuries, the marginal buyers have shifted to hedge funds . Unlike buy-and-hold central banks, hedge funds trade actively and demand higher risk premia (term premiums) in the face of excessive supply, acting as "bond vigilantes" that push yields higher .

"Borrowing more to pay off debts": An era where 80% of global government borrowing is for refinancing

Global government debt is expanding not just because of new deficit spending, but primarily because of maturity rollovers . Around 80% of total global government borrowing (and roughly 70% in the US) is for refinancing (rollovers) existing debt rather than funding new initiatives . In the past low-interest-rate era, rolling over debt was cheap . Today, doing so under a high-interest-rate regime means compounding debt service costs exponentially, creating a vicious cycle of rising fiscal pressure .

If the speed accelerates further, it explodes: The real risks currently hidden by the market

The market is currently masking underlying vulnerabilities (such as weak employment and soaring debt) by betting heavily on tech/AI-driven growth . However, the true hidden risk is that if interest rate acceleration picks up pace again (e.g., rushing rapidly from 5%–5.3% toward 6%), or if structural factors like supply-demand imbalances, sticky inflation, and Yen carry trade unwinding converge, the system will face a breaking point where refinancing costs and term premiums overwhelm market stability .
