• The Dow Jones declined heading into the first American market session of September.
• Renewed broad-market bond, government financing, and inflation concerns weigh on investors.
• US Manufacturing PMI figures showed a sixth straight month below 50 as tariffs weigh on companies.

The Dow Jones Industrial Average (DJIA) shed around 550 points on Tuesday, with American markets returning from a long weekend with renewed selling pressure. Rising bond yields, government funding concerns, and fresh inflation concerns pummel investor sentiment through the overnight session. US markets flubbed an attempt to right the equities ship after Institute for Supply Management (ISM) Manufacturing Purchasing Managers Index (PMI) figures showed a sixth straight month of contraction fears as firms continue to grapple with trade uncertainty.

Stocks shudder to start September

Equity markets took a hit through the overnight session after global bond markets saw rising yields, driven in no small part by fresh concerns about government financing and debt levels across most of the developed world. Bearish momentum extended into the American market session, dragging US equity indexes lower across the board. September is historically a bad month for equities, and the trend appears to be intact at the outset.

The ISM’s latest Manufacturing PMI rose to 48.7 in August, rebounding from the previous month’s 48 but still falling just shy of the expected 49. The PMI posted its sixth straight month below the investor-eyed 50.0 level. Digging into the details of the report, gains are mostly being driven by price increases as inventories empty faster than they can be refilled. Manufacturing companies are broadly avoiding extra hiring in the face of tumultuous trade policies from the Trump administration, crimping supply chain stability. Inventories that surged to multi-year highs in the first half of the year are beginning to run dry, and companies are competing for limited goods as manufacturers continue to throttle back output capacity.

ISM PMI respondents target tariffs

Respondents to ISM’s PMI survey specifically noted that tariff impacts are still looming over the horizon. Unexpected import tariff increases targeting Brazil and India, as well as the elimination of sugar quotas and the rapidly rising cost of construction goods, were specifically highlighted as causes for a growing dry-up in new order growth. Trucking backlogs are declining rapidly, with respondents noting that activity levels are now worse than they were during the 2008 global financial crisis.

JOLTS Job Openings from July are due on Wednesday, and will be followed by the ISM’s Services PMI component on Thursday, with US Nonfarm Payrolls (NFP) due on Friday. JOLTS have had a rough run as of late, with a poor correlation to US NFP figures over the past two years, but the private payroll estimator is set to take on renewed importance to investors who are rapidly losing faith in official figures. The Trump administration has been fast-tracking its strategy of sacking officials who allow unfavorable economic data to be published, putting pressure on investors to consider where they will get accurate data in the future.
