Tale of Two Economies Continues, with Policy Becoming a Headwind.
The build-out of artificial intelligence (AI) continues to elevate business investment and is resulting in soaring profits, while waning tax refunds and higher borrowing costs threaten to slowdown consumer spending. Policy may remain active source of volatility this autumn as the Treasury and Federal Reserve (Fed) are challenged by high inflation, bloated debt and deficits, and the AI investment boom. Meanwhile, midterms loom, with trade policy and geopolitical strains continuing to frame an uncertain macro backdrop.

Inflation Remains the Primary Challenge amid Growth Surge.
Growth has been accompanied by stickier-than-expected inflation, prompting markets to turn their attention to the degree and duration of policy tightening by the Fed. The dual support of fiscal and monetary policy has enabled markets since 2022, so the rate hike cycle and less fiscal impulse could pressure risk assets in the short run, offsetting some of the positive economic backdrop. Geopolitical risks also remain a source of inflation pressure as they create persistent supply chain strains.

Yields Have Suddenly Become a Challenge for Stocks to Overcome.
Stocks slid this month as the fed hiked and yields surged, possibly setting equities up for a bumpy ride to close the year. Though hiking cycles haven't usually derailed stocks, they have come with significant drawdowns as markets digest the sea change. Still, earnings remain the core driver of the move higher and valuations could continue to contract as higher rates slow the pace of gains. On that front, fuel prices might prove to be the key risk to watch in 4Q. Surging diesel and gas prices have already caused some near-term cuts to discretionary, staples and industrials stocks and the longer the war in Iran lingers, the greater the downside revision risk.

The Brightside of the Bond Market Meltdown.
While yields may remain pressured by secular drivers such as fiscal deficits and the debt burden, as well as cyclical pressures from growth and inflation, yields at 5% across the curve offer prospects for a positive return for bonds for the first time in years. The municipals market disruption in September was particularly profound. Corporate credit spread widening has been concentrated in the lowest quality segment of the market.
