How JPMorgan traders see the Fed decision this week going down and market reaction

The Federal Reserve is widely expected to cut its overnight rate by 25 basis points this week, with a 96% probability priced in by traders, though the market's reaction will largely depend on the central bank's forward guidance. JPMorgan's analysis outlines key scenarios: a 'dovish' 25 bps cut (47.5% chance) could boost the S&P 500 by 0.5-1%, while a 'hawkish' 25 bps cut (40% chance) might lead to a flat to 0.5% decline. Less probable outcomes, such as a 50 bps cut (7.5%), an unexpected hold (4%), or a rate hike (1%), carry significant and varied market implications, including potential S&P 500 swings of up to 4%.

Analysis

The market is overwhelmingly positioned for a Federal Reserve rate cut this week, with traders assigning a 96% probability to a 25 basis point reduction according to the CME Group's FedWatch tool. The critical determinant for market direction, however, will be the central bank's forward guidance. Analysis from JPMorgan's trading desk quantifies this uncertainty, assigning a 47.5% probability to a 'dovish' cut that could lift the S&P 500 by 0.5%-1%, versus a 40% chance of a 'hawkish' cut that could push the index down by as much as 0.5%. The distinction hinges on whether the Fed prioritizes a non-inflationary labor market, allowing for an accommodative stance, or expresses concern over strengthening hiring data, prompting a more cautious tone from Chair Powell. While a 25 bps cut is the base case, tail-risk scenarios carry significant potential impact. A surprise 50 bps cut (7.5% probability) could swing the S&P 500 between a 1.5% loss and a 1.5% gain, depending on whether it is perceived as a panic signal or a proactive measure. Highly improbable outcomes like a hold (4% chance) or a hike (1% chance) are projected to trigger sharp sell-offs of 1%-2% and 2%-4%, respectively.

Key Decisions for Investors

• Given that a 25 basis point cut is fully priced in, investors should focus on the Fed's forward guidance and Powell's commentary on the labor market versus inflation, as this will be the primary market-moving catalyst.
• Consider hedging against a 'hawkish cut' scenario, as JPMorgan assigns it a substantial 40% probability which could result in a negative market reaction.
• Prepare for heightened volatility around the announcement, as even the less likely scenarios, such as a 50 bps cut, present a wide and binary range of potential outcomes for the S&P 500.
• Investors should not be positioned for a significant rally, as the most probable 'dovish' outcome projects a modest S&P 500 gain of just 0.5%-1%, while the downside risks from a hawkish surprise or an unexpected hold are more pronounced.
