The U.S. bond market sounds the alarm! PPI beats expectations, coupled with rising oil prices, causing concerns of stagflation to rapidly intensify.

Inflation pressures in the United States have heated up again, exacerbated by the conflict in the Middle East pushing up energy prices. The bond market issued a warning signal on Wednesday, and market concerns about stagflation risks have significantly increased. Stagflation refers to a situation where inflation rises while economic growth slows down, which often creates multiple pressures on corporate profits, stock and bond performance, and monetary policy space, and is considered one of the macro situations investors are least willing to see. Data released on the same day showed that the U.S. Producer Price Index (PPI) rose for the third consecutive month in February, further exacerbating market concerns. The overall PPI rose by 0.7% month-on-month, the largest increase in seven months, and the core PPI rose by 0.5%, indicating that upstream price pressures are building up. After the data was released, U.S. Treasury bonds were sold off, short-term interest rates spiked, with the 2-year U.S. Treasury yield rising by 7.2 basis points to 3.74%, close to the high point since last August, while the stock market significantly declined, with the Dow, S&P 500, and Nasdaq all recording declines of over 1%. Adjustments in the bond market were already evident before the data was released. Influenced by the Middle East situation, international oil prices continued to rise, with Brent crude oil briefly surpassing $109 per barrel. Prior to this, the United States and Israel launched airstrikes on key Iranian natural gas facilities, triggering market concerns about energy supply disruptions and increasing the risk of inflation rebound. With the PPI data surpassing expectations, bond market sell-offs intensified. Against this backdrop, the Federal Reserve announced on the same day that it would maintain interest rates in the range of 3.5% to 3.75% unchanged and acknowledged that the Middle East situation brings uncertainty to the economic outlook. Federal Reserve Chairman Jerome Powell said at a press conference that the committee had discussed whether another rate hike was needed, but stressed that this was not the current basic scenario. He also pointed out that stagflation should not be used to describe the current economic situation, believing that the current unemployment rate is still close to the long-term normal level and inflation is far from reaching the high levels seen in the 1970s. However, market concerns about stagflation risks are still on the rise. Subadra Rajappa, head of research at French Industrial Bank, said that the PPI data exceeding expectations at both the overall and core levels further reinforced concerns about stagflation and supported the Federal Reserve's stance on maintaining interest rates unchanged this year. At the same time, the U.S. Treasury yield curve has exhibited a trend of "bear flattening," with short-term yields rising faster than long-term yields, reflecting market expectations of potentially tighter monetary policy than before, as well as a more cautious attitude towards future economic growth. Data shows that the spread between the 2-year and 10-year U.S. Treasury yields has narrowed to 51.5 basis points, significantly smaller than the approximately 74 basis points in early February. Gary Schlossberg, strategist at Wells Fargo Investment Institute, said that the flattening yield curve indicates that the market is more cautious about the Federal Reserve's policy outlook and has also heightened concerns about stagflation. However, he believes that this risk is not yet sufficient to evolve into a long-term stagflation scenario similar to the 1970s, but more likely to be a temporary phenomenon. Some market participants still hold a relatively moderate view of stagflation risks. Tom Hainlin, strategist at U.S. Bank Asset Management Group, pointed out that the current situation is more like a typical energy shock event rather than a comprehensive stagflation cycle. He said that as long as high oil prices have not fully transmitted to long-term inflation expectations, it does not mean that the economy has entered a stagflation phase.
