WASHINGTON

US employers added just 134,000 jobs in September, the fewest in a year, though the figure was likely lowered by Hurricane Florence, while the unemployment rate fell to 3.7 per cent, the lowest level since 1969.

Hurricane Florence struck North and South Carolina in the middle of September and closed thousands of businesses. A category that includes restaurants, hotels and casinos lost jobs for the first time since last September, when Hurricane Harvey had a similar effect.

Even with unemployment now at a historic low, average hourly pay increased just 2.8 per cent from a year earlier in September, one tick below the yearly gain in August.

September extended the longest streak of hiring on record, with millions of Americans having gone back to work since the Great Recession. Healthy consumer and business spending has been fuelling brisk economic growth and emboldening employers to continue hiring. The September gain extended an 8-year streak of monthly job growth.

Consumers, business executives and most economists remain optimistic. Measures of consumer confidence are at or near their highest levels in 18 years. Retailers have begun scrambling to hire enough workers for what’s expected to be a robust holiday shopping season. A survey of service-sector firms, including banks, hotels and health care providers, found that they are expanding at their fastest pace in a decade.

Americans have continued spending steadily and appear to be in generally stable financial shape. Households are saving nearly 7 per cent of their incomes — more than twice the savings rate before the recession. That trend suggests that a brighter economic outlook hasn’t caused consumers to recklessly build up unsustainable debt.

During the April-June quarter, the US economy expanded at a 4.2 per cent annual rate, the best in four years. Economists have forecast that growth reached a 3 per cent to 3.5 per cent annual rate in the July-September quarter.

The economy does show some weak spots. Sales of existing homes have fallen over the past year. Increasingly expensive houses, higher mortgage rates and a shortage of properties for sale are slowing purchases. Auto sales have also slumped.

Other threats loom, too. Borrowing costs for businesses and consumers are rising. Pointing to the economy’s health, the Federal Reserve last week raised the short-term interest rate it controls and predicted that it would continue to tighten credit into 2020 to manage growth and inflation. Over time, higher borrowing costs make auto loans, mortgages and corporate debt more expensive and can eventually slow the economy.

But for now, anticipating stronger growth — and perhaps higher inflation — investors have dumped bonds and forced up their yields. The yield on the government’s 10-year Treasury note, a benchmark for mortgages and other loans, has touched its highest level in seven years.

President Donald Trump’s trade fights could also weigh on the economy, though the effect on hiring won’t likely be felt until next year, economists say. The Trump administration has imposed tariffs on imported steel and aluminium as well as on roughly half of China’s imports to the United Sates. Most US businesses will try to absorb the higher costs themselves, at least for now, economists say, and avoid layoffs.

Still, should the tariffs remain fully in effect a year from now, roughly 300,000 jobs could be lost by then, according to estimates by Mark Zandi, chief economist at Moody’s Analytics.
