Markets face a pivotal moment this week as U.S. Treasury investor sentiment has shifted markedly, with many betting on continued bond price gains. On Monday, the U.S. 10-year Treasury yield intraday fell to 4.046%, marking a five-month low since early April. Over the past four trading sessions, the yield has dropped a cumulative 22.4 basis points, representing the largest four-day decline since early April. According to Dow Jones Market Data, this trend indicates investors are rapidly flowing into the Treasury market, seeking both safe-haven assets and potential returns. Declining Treasury yields signify rising bond prices.

With U.S. Treasuries rallying consistently since early this month, investors are positioning ahead of a series of major data releases this week, capitalizing on the trading window. The first closely watched data point will be released Tuesday, when the Bureau of Labor Statistics (BLS) publishes revised employment data covering the 12-month period through March. This revision will be based on a more comprehensive dataset including state unemployment insurance records, and markets widely expect the revision to show U.S. job growth was significantly lower than previously reported official data.

Goldman Sachs projects that U.S. employment data has been overestimated by as much as 80,000 jobs per month over the past year, while Deutsche Bank estimates the overestimation ranges between 50,000 to 60,000 jobs. Should the revision confirm this assessment, it would indicate the U.S. labor market's actual performance has been weaker than currently perceived by markets.

Such weak economic data would strengthen the Federal Reserve's case for rate cuts and drive further capital flows into the bond market, thereby pushing 10-year Treasury yields even lower. Padhraic Garvey, Head of Research at ING Groep NV, noted in a research report: "We expect the 10-year Treasury yield to continue testing the 4% level, and if successfully breached, yields could continue declining in the short term." He predicts yields may fall further to 3.75%, but as inflation rebounds in coming months, yields will quickly rebound to around 4.5%.

Rising inflation erodes the real value of bonds' fixed returns, forcing investors to demand higher yields to hedge against risk. Therefore, another market focus will be Thursday's inflation data release. Economists expect the U.S. August Consumer Price Index (CPI) to rise 0.3% month-over-month, matching July's pace, while core CPI excluding volatile food and energy items is also expected to maintain the same increase.

Last year's unexpected inflation rebound drove 10-year Treasury yields higher even after the Federal Reserve's September rate cut. Markets currently widely expect the Fed to announce another rate cut at next week's meeting. However, some institutions express concerns about rate cuts. Will Denyer, Partner and Chief Economist at Gavekal Research, stated: "Given upcoming tax cuts and the full impact of tariffs yet to materialize, markets may view another rate cut as a policy mistake. If so, the bond market could see selling pressure."

Generally, both tax cuts and tariffs are viewed as inflation-driving factors, creating dual pressure on bonds. This week also requires attention to Treasury Department bond auctions. On Wednesday, the U.S. Treasury will issue $39 billion in 10-year notes, with investors closely watching whether the government needs to offer higher yields to attract buyers amid increased debt issuance.

Additionally, 3-year and 30-year Treasury auctions will be held Tuesday and Thursday respectively, but these maturity bonds have relatively limited impact on market supply-demand expectations, with market focus remaining concentrated on the 10-year Treasury auction.
