The Sahm Rule signal: On the blink or flashing red?

Summary

Rising unemployment over the past year has sent the clearest signal yet that the labor market is weakening. While the Sahm Rule indicator—which highlights the historical pattern that the unemployment rate has never risen 0.5 points above its prior 12-month low without a recession—has not crossed its recession threshold, the current rise would nonetheless be unique if a downturn in the labor market were to be avoided. Of course, this has been a unique labor market, with the pandemic initially delivering a massive shock to labor supply. Is the recovery in labor supply now interfering with the Sahm Rule signal?

At 0.43, the Sahm Rule indicator has already risen more than at the onset of any recession in the past 50 years. Yet entrants into the labor force, particularly re-entrants, have been an unprecedented driver of the increase. This should assuage some concern over the current rise as it comes in larger part for the “right” reason of more workers entering the jobs market, which ultimately makes it easier for businesses to grow.

Yet the increase in the unemployment rate for the “wrong” reasons is troubling in its own right. Looking at the rise in unemployment due to job loss on the same basis as the traditional Sahm Rule shows an increase similarly reminiscent of periods when the labor market was on the brink of a downturn.

Could this be the cycle where the Sahm Rule breaks? The larger lift from labor force entrants and more gradual ascent compared to the starting point of prior recessions raises the likelihood. That said, the negative feedback loop between rising unemployment and declining spending means that neither the current increase in the traditional Sahm Rule indicator nor the job loser version should be brushed aside. Recession thresholds crossed or not, the increase in both values shows an unequivocal deterioration in the labor market. With momentum in the jobs market difficult to shift, we see the risk of recession remaining unusually high at the moment.

GBP/USD remains offered; bears target 1.3600

GBP/USD now leaves behind part of its recent recovery and revisits the low 1.3600s at the beginning of the week. Indeed, Cable trades with a mild downward bias amid decent gains in the Greenback as investors remain wary of upcoming US data releases and the Jackson Hole event.

EUR/USD remains sidelined above 1.1650

EUR/USD trades on the defensive following the closing bell on Wall Street on Monday, hovering around the 1.1660 region and adding to Friday’s small decline. The pair’s pullback comes in response to an acceptable rebound in the US Dollar in a context of generalised caution ahead of key US data releases and Chair Warsh’s speech in Jackson Hole.

Gold poised to extend its bullish run

Gold surrenders part of its initial advance, although it keeps its bullish pace well and sound above the $4,600 mark per troy ounce on Monday. The precious metal’s move higher comes despite slight gains in the US Dollar and a modest pullback in US Treasury yields across the curve.

XRP surged 72%, but is the rally really about XRP?

Ripple (XRP) surged more than 72% in less than a week, its strongest rally since July 2025, as cryptocurrency prices broadly broke out. But the move has a problem: it may have little to do with XRP itself. The token's near-term rally appears to have been driven largely by a broader liquidity shift after the US Treasury expanded long-end bond buybacks, pulling yields lower and lifting risk assets.

Convulsion in credit markets

The United States government just posted a $432.3 billion deficit for July, the largest monthly shortfall since March of 2021. That single burst of red ink pushed the yeartodate deficit to $1.8 trillion, with two months still remaining in fiscal 2026. At this pace, Washington will soon wax nostalgic for the “good old days” when annual deficits were only $2 trillion.

$20 billion offered, $2 billion taken: Why Treasury doubled its buyback cap

The US Treasury moved off its own calendar on Wednesday, and that is the part worth sitting with. At 12:32 GMT, the department said it would at least double the size of liquidity support buyback operations in the 10-year to 20-year and 20-year to 30-year sectors, lifting the maximum from $2 billion per operation to at least $4 billion, effective September 9 and running to November 4.
