Fourfold shock from growth, oil prices, the Fed, and bidding

[Block Media Reporter Lee Jeong-hwa] The US bond market has been engulfed in a sudden sell-off. Strong economic growth, high oil prices, a hawkish Federal Reserve (Fed), and weak government bond auctions have all converged. Wall Street diagnosed that a "perfect storm" has hit the bond market, pushing interest rates higher.

The yield on the US 10-year Treasury bond has soared above 5.1%, reaching its highest level since 2007. The 5-year yield also surpassed 5%. As strong economic performance and persistent inflation have been confirmed instead of the expected economic slowdown, the outlook for further interest rate hikes is rapidly spreading.

The New York stock market has declined, and Bitcoin has dropped to around $84,000, negatively impacting the overall financial investment market.

US Bond Market 'Meltdown'... Atmosphere Changes in One Day

On the 23rd (local time), the US Treasury market showed a sharp selling trend. The yield on the 10-year Treasury bond surged by about 17 basis points (0.17 percentage points) during the day, reaching 5.13%. This is the highest level since 2007. The daily increase was the largest since the announcement of former President Donald Trump's so-called "Day of Liberation" tariffs in April 2025.

The yield on the 5-year Treasury bond jumped by about 20 basis points, surpassing 5%. This is the first time the 5-year yield has crossed 5% since 2007. The 30-year yield also rose to around 5.4%, reaching its highest level since 2007. Bond prices and yields move inversely. The sharp rise in yields indicates a strong sell-off in government bonds.

Local media outlets such as The Wall Street Journal (WSJ) and Bloomberg urgently reported the unstable state of the US Treasury market through interviews with bond experts.

Subradhar Rajappa, head of US research at Société Générale, described the situation in one word: "meltdown." He diagnosed that the sell-off that began in the global bond market is spreading as it breaks through major interest rate lines, seemingly losing control.

Sean Simko, head of bond investment management at SEI Investments, stated, "I wouldn't want to stand in front of a freight train today." He explained that strong economic indicators, government bond supply, and persistent inflation worldwide are simultaneously pressuring the market.

This surge is not due to a single negative factor. Strong economic growth, rising oil prices, expectations of further tightening from the Fed, and deteriorating government bond supply have all occurred at once.

The first shock was oil prices. Amid ongoing tensions in the Middle East, international oil prices have surged again. According to the WSJ, Brent crude exceeded $103 per barrel during the day. Concerns that rising energy prices could rekindle inflation led to the sell-off in government bonds.

The second shock was the unexpectedly strong US economy.

The S&P Global US Composite Purchasing Managers' Index (PMI) showed that business activity in the manufacturing and services sectors is growing at the fastest pace in over five years. The pace of job growth is also the fastest in over four years. This was bad news for the bond market, which had expected an economic slowdown.

Christopher Sullivan, Chief Investment Officer (CIO) at the UN Federal Credit Union, stated that considering issues from Iran to the resilient US economy, it makes little sense for many to hold bonds at the current level.

Isaac Brook, US interest rate strategist at RBC Capital Markets, said it is very difficult for investors to view the current market positively. While government bonds may appear attractive based on yield levels, rates have continued to rise every time they were judged to be at a low point over the past six months.

The Fed Moves Again... Market Reflects Three Rate Hikes Over the Next Year

The Fed has delivered a bigger shock to the bond market.

Last week, the Fed raised the benchmark interest rate for the first time in three years to 3.75-4.00%. Fed Chair Kevin Warsh explained that this move has removed some accommodative aspects from monetary policy.

On the same day, Fed Governor Michael Barr reiterated the possibility of further rate hikes. He stated, "Inflation is above the 2% target, and it is not clear that we are on track to reach that target in a timely manner."

Dhiraj Narula, HSBC's US interest rate strategist, explained that the market is concerned that the Fed is willing to raise rates to curb inflation, even in the face of supply shock-induced price pressures. This suggests that the Fed's hawkish policy may persist for an extended period.

Christophe Boucher, CIO at ABN AMRO Investment Solutions, noted that pressure is beginning to build in the short end of the yield curve. He analyzed that strong economic indicators provide further justification for the Fed to adopt a more hawkish stance.

Changes are also evident in market prices. The interest rate swap market is fully reflecting three additional rate hikes of 0.25 percentage points each over the next year. There is also significant demand for hedging against the possibility of a fourth hike.

If realized, the Fed's benchmark rate could rise to 4.75-5.00%. This is in stark contrast to the rate cut expectations that had dominated the market just a short time ago.

The Final Blow: Treasury Auction... "No Buyers"

The final blow to an already shaky bond market was the US Treasury's auction of 5-year bonds.

The auction yield for the $70 billion (approximately 98 trillion won, based on an exchange rate of 1,400 won) 5-year bonds was set at 5.033%. This is the highest auction yield since 2006. It was awarded at a level more than 3 basis points higher than market expectations.

According to Bloomberg, this was the second worst 5-year auction in related statistics since 2018. The fact that dealers took on more volume than expected was interpreted as a signal of weak demand from final investors.

The WSJ analyzed that as bond prices fell, investors were unwilling to buy bonds, and the poor auction results further fueled investor anxiety, creating a vicious cycle that pushed rates even higher.

Brendan Phelan, Bloomberg Markets Live macro strategist, diagnosed the current situation as "strong growth, persistent inflation, uncertainty surrounding the energy market, and a hawkish Fed creating a near-perfect storm for rising rates."

The Treasury's bond buyback program also failed to change the mood. The Treasury expanded its long-term bond purchases to $6 billion (approximately 840 billion won), but the market showed little reaction.

The problem is that the rise in Treasury yields does not remain confined to the bond market.

The yield on the 10-year Treasury bond serves as a benchmark for a wide range of financial products, from US mortgages to corporate bonds. The higher the yield remains, the higher the financial costs for households and businesses.

The overall financial market reflected an unstable state. On that day, the S&P 500 index fell by 0.8%, the Nasdaq Composite index by 1.1%, and the Dow Jones Industrial Average by 0.7%. Bitcoin halted its upward march toward $90,000 and retreated to the $84,000 level.

Scott Kimball, CIO of Loop Capital Asset Management, stated, "The risk asset market is relatively holding up well, but for now, it seems to be a problem of the interest rate market itself."

Ultimately, the question posed by the market is simple. Is the yield that has surpassed 5% high enough to attract bond buying, or considering the strong growth and inflation in the US and further tightening, is it still not high enough?
