Why Is the "Breaking 5" in U.S. Treasury Yields So Important?

1. Why is the "breaking 5" in U.S. Treasury yields so significant?
The 30-year U.S. Treasury yield is regarded as the "anchor" for global asset pricing, and its fluctuations directly influence the valuation logic of all financial assets. On May 14, the yield on the $25 billion 30-year Treasury auction reached 5.046%, marking the first time since the pre-2007 financial crisis that a new issuance of ultra-long bonds carried a 5% coupon rate.

This number is alarming because:

- Risk-free rate rising: When investors can earn over 5% annualized return with near-zero risk in U.S. Treasuries, risk assets like stocks, real estate, and cryptocurrencies must offer higher expected returns to remain attractive.
- Overall funding costs increase: Corporate financing, mortgage rates, and consumer credit costs all rise, suppressing real economic activity.

2. The four main drivers behind this round of soaring U.S. Treasury yields

1. Out-of-control U.S. fiscal "black hole"

The total U.S. federal debt has approached $39 trillion, with a projected deficit of $1.9 trillion in fiscal year 2026, accounting for 5.8% of GDP. To fill the gap, the Treasury continues to issue large amounts of long-term debt, with net borrowing in Q2 increased to $189 billion. This "new debt to pay old debt" model creates enormous bond supply pressure, prompting buyers to demand higher yields as compensation.

2. Inflation stickiness exceeding expectations

In April, U.S. CPI year-over-year rose 3.8%, higher than March's 3.3%, the highest since June 2023; core CPI increased 2.8% YoY, also above previous levels. Energy price shocks (driven by tensions in the Middle East causing oil prices to surge) are transmitted through gasoline, transportation, food, and other chains into a broader price system, reigniting inflation expectations.

3. Geopolitical conflicts igniting energy risks

Recurrent U.S.-Iran tensions threaten disruption of energy transportation routes through the Strait of Hormuz, with international oil prices continuing to rise (WTI has broken through $105 per barrel). Rising oil prices further boost inflation expectations, and markets are beginning to worry about "stagflation"—a vicious cycle of low growth and high inflation.

4. The Federal Reserve's policy path has completely reversed

At the start of the year, markets widely expected multiple rate cuts by the Fed this year, but current CME FedWatch data shows that the market has largely ruled out rate cuts this year, with a 97.1% and 96% probability of holding rates steady in June and July, respectively. More severely, Fed interest rate swap contracts have begun pricing in a 25 basis point hike, with a 100% chance of a rate increase by March 2027. This indicates that the Fed will not only refrain from cutting rates but may be forced to resume tightening.

3. Impact on global markets: a wave of "asset revaluation"

1. Stock markets: high-valuation tech stocks hit hardest

On May 15, U.S. stocks experienced a broad sell-off: S&P 500 down 1.24%, Nasdaq down 1.54%, Dow Jones fell below 50k points. The rise in risk-free rates significantly reduces the present value of future cash flows, making high-valuation growth stocks like AI and semiconductors the most affected.

2. Gold: temporary loss of safe-haven function

Gold, typically seen as a safe asset, faced a single-day plunge of 3% in COMEX futures, with silver dropping over 10.47%. A rare "triple kill" of stocks, bonds, and currencies has emerged in the market.

3. Exchange rates: U.S. dollar strengthening across the board

The dollar index rose to 99.278, while non-U.S. currencies generally declined: offshore RMB depreciated to 6.8139, the yen fell below 158, and the euro dropped to 1.1630. Capital is rapidly flowing back into the U.S., putting dual pressure on emerging markets through capital outflows and currency depreciation.

4. Cryptocurrencies: failed to serve as a safe haven

Bitcoin fell below $80k, Ethereum dropped over 3%, demonstrating the vulnerability of high-beta risk assets.
