The possibility that the U.S. economy is headed for a recession over the next year has risen sharply, according to UBS.

In its latest economic forecasting, the bank's economists and strategists say data is pointing toward a 60% chance of a recession ahead, up from 40% from the latest reading in June.

UBS measures three components: hard macro data, the yield curve across various Treasury maturities, and credit data such as nonperforming loans and feedback from the Federal Reserve's Senior Loan Officers' Survey.

Using data alone, "the probability of being in a contractionary phase is historically very high — 94% in July vs 35% in April — but in the current case, the US team's modal forecast is that the contraction does not morph into a full-blown recession," UBS said in a note.

The news also isn't good when looking at Treasury yields.

A key part of the curve, comparing 10-year yields to 2-year, has been inverted since early July. The rest of the curve looking at 1- to 10-year maturities is "downward sloping, as it usually is prior to recessions," UBS said. The chance of a recession from the bond space is now at 71%, up from 57% in July.

One bright spot is credit: the sector is showing just a 15% chance of recession, as metrics in that space still appear mostly positive.

The U.S. has seen two consecutive quarters of negative growth, a traditional recession sign, though the last word usually goes to the business cycle dating committee at the National Bureau of Economic Research. Most economists think the NBER will not rule the U.S. in recession for the first half of the year.

The recent market downturn is starting to do some technical damage.

Tuesday's losses pushed the S&P 500 back below its 50-day moving average, a key level watched by traders and strategists. It marked the first time since July 26 that the broad market index traded below that level.

Tuesday also marked the first time since July 28 that the S&P 500 broke below 4,000.

As stocks sell off for a third straight day, investors are still wrapping their heads around the comments made by Fed Chair Jerome Powell in Jackson Hole, Wyoming on Friday.

Rod von Lipsey, managing director at UBS Private Wealth Management, said investors "are coming to terms with the idea that the Fed is serious about curbing inflation, even as recent data suggests inflation is starting to decline."

"We believe the market's summer rally was ephemeral," he added, "and continue to recommend that investors remain selective and focus on defensive stock sectors like health care and dividend-paying stocks."

Energy and utilities are the only S&P 500 sectors trading in positive territory as August nears an end.

While energy was the worst-performing sector on Tuesday and fell about 4% as of midday trading, it's on track to end August with a 2.7% gain. Energy is also one of just two sectors currently trading in positive territory year to date – up more than 45%.

Meanwhile, utilities is on pace to end August 1.3% higher and is up about 4.6% since the beginning of January.

On the flip side, healthcare and information technology are currently leading August's declines across the S&P 500's sectors, down more than 5.1% and 5.7%, respectively, since the beginning of the month.

Chris Hyzy, Bank of America Private Bank CIO, said on "Halftime Report" that investors should shift into defensive stocks now that Federal Reserve officials have pushed back on the market's expectation for rate cuts in 2023.

"If it's higher for longer, you really should be looking at high free cash flow areas, pricing power areas, demand that is going to hold up relative to supply," Hyzy said.

Market expectations have shifted toward higher rates over the past week as central bankers, including Jerome Powell last Friday and John Williams on Tuesday, have reiterated the Fed's commitment to fighting inflation. The CME FedWatch tool now shows that traders expect the Fed to hike rates to range of 3.75% to 4.00% by December, and to keep it at the level or hike even further in the first half of next year.

Hyzy did say he was bullish long-term but said the market would need a reset over the next six to nine months.

"June's growth rates for all three composites are at or above the 95th percentile of historical experience. For the first six months of 2022, in fact, the National Composite is up 10.6%."

The Conference Board's consumer confidence index came in at 103.2 for August, up from a July print of 95.3 and above a StreetAccount estimate of 97.4. It also marked the index's first gain after falling for three straight months.

"The Present Situation Index recorded a gain for the first time since March. The Expectations Index likewise improved from July's 9-year low, but remains below a reading of 80, suggesting recession risks continue. Concerns about inflation continued their retreat but remained elevated," said Lynn Franco, Senior Director of Economic Indicators at The Conference Board.

Historically, the market could count on the Federal Reserve to step in with easy policy to help limit big losses in equities, which has been known since the days of former Fed Chair Alan Greenspan as "the Fed put." But that lifeline could be dead, for now, according to Scott Ladner, chief investment officer at Horizon Investments.

"Bad economic news is once again bad market news," he said. "In an environment where you believe the Fed will pivot to a more dovish policy if the economy weakens, bad economic news can be interpreted bullishly because it speeds the time of such a dovish pivot."

"In an environment where the Fed has been clear that they will sacrifice the economy (to what extent, still unknown) to squash inflation, that stance no longer makes sense and bad economic news just increases the chance of recession which decreases earnings potential without the possibility of a Fed backstop," he added. " Said another way, the 'Fed put' is currently dead."
