Stocks slump in a losing week

Wall Street ended the day and the week in the red, as volatility in the bond market pulled stocks lower.

The S&P 500 (^GSPC) lost 1.3%, while the Dow Jones Industrial Average (^DJI) shed 0.9% or roughly 300 points.The tech-heavy Nasdaq Composite (^IXIC) lost 1.5%. All the major indexes ended the week lower than where they started.

A look at the week ahead

The largest and most influential tech companies are reporting earnings next week, providing a key perspective on the health of the economy and the impacts of the Fed's tightening campaign. Amazon, Meta, Alphabet and Microsoft are among the dozens of companies reporting during the final full week of October.

Investors will also get a fresh look at the central bank's preferred inflation gauge, alongside another survey on the mood of the American consumer.

How the Israel-Hamas conflict unfolds will also be top of mind for policymakers and investors. Market watchers will also continue tracking the surge in bond yields as they hover just under 5%.

Yahoo Finance's Brent Sanchez has a graphical breakdown of what to watch next week:

Middle East tensions spark potential for energy shocks

Policymakers in Washington are closely watching the situation in Gaza, which risks expanding into a regional conflict and carries implications for the energy market.

Fed Chair Jerome Powell said in a speech Thursday that the central bank is monitoring the developments for economic implications. "Geopolitical tensions are highly elevated and pose important risks to global economic activity," he said.

The potential for energy shocks comes from the region's role in the oil market, specifically how Iran will respond as the violence escalates. Earlier this week Iran's foreign minister called for an embargo against Israel, as the Israel-Hamas war approaches its second week.

"Iran's involvement is the key focus for the crude market and this is essentially because they are a huge crude producer," Rebecca Babin, CIBC Private Wealth energy trader, told Yahoo Finance Live.

The turmoil could continue to push oil prices higher, injecting even more volatility into an energy market that has been at the forefront of the debate surrounding inflation. Higher prices would further complicate the Fed's mission to bring down inflation. And similar to the Russian invasion of Ukraine, dealing with the potential of a Middle East energy shock would fall outside of the control of the central bank, even as the Fed would have to contend with the fallout.

Expectations are front and center in the Fed’s inflation fight

In the Fed’s struggle to bring inflation back down to 2%, Americans' expectations of where inflation is heading plays a crucial role.

Fed Chair Powell keeps saying inflation is too high, and it’s not just because the numbers say so. It's also an attempt to set expectations. Where inflation is concerned, what Americans think will happen has a way of becoming what happens, just as the Fed’s threats of more rate hikes are meant to foreshadow a future course of monetary policy.

"Doing too little could allow above-target inflation to become entrenched and ultimately require monetary policy to wring more persistent inflation from the economy at a high cost to employment," Powell said in a speech Thursday before the Economic Club of New York.

The Fed’s forward guidance and its use of public communications to steer policy can look and sound a lot like wishful thinking. But it does have real impacts. The threat of a hike can almost function like another phantom rate hike. And part of getting that desired outcome is repeating again and again that it will happen until it does.
