The stock market may react positively to a Fed rate hike at this week's FOMC Meeting, while reacting negatively if the Fed does not hike. The markets raised their probability of a Fed rate hike after the high August Core CPI was released on Friday. Are they right? There continue to be mixed considerations.
Possible Stock Market Reaction
Stocks may view a rate hike positively for several reasons. /1/ With the Fed finally moving against inflation, longer-term Treasury yields could fall. The short-end would be taking on some of the anti-inflation work. /2/ Tighter policy now may reduce the extent of tightening needed later. /3/ A tighter Fed could reduce the risk premium in commodity prices. Lower commodity prices, particularly oil, should be a positive for stocks. It also would work to lower longer-term yields.
In contrast, steady Fed policy could lift inflation expectations and prompt further increases in commodity prices and longer-term yields, both of which would be negative for stocks. Also, the risk of Fed tightening after the mid-term elections would increase, possibly by more than if the Fed had moved sooner. So, this risk would continue to weigh on stocks. And, the markets could conclude that the Fed was bowing to pressure from the Administration, damaging its reputation of being politically independent.
Arguments For/Against a Hike
1. While the 0.3% m/m August Core CPI was on the high side, large increases in a couple of components -- Airfares and Lodging Away From Home -- were mainly responsible. Higher fuel costs were likely behind the jump in Airfares for the second month in row. Volatility appears to be behind the bounce in Lodging after the latter dropped in July. The bulk of the Core components were benign. The Cleveland Fed's measure of the median CPI and trimmed CPI both rose only 0.2% in August. So, "fence sitter" FOMC members could decide to keep policy steady despite the high print, blaming it on a "bad" distribution of "noise" and higher oil prices this month. However, they may vote to tighten in response to the stickiness of inflation.
2. A desire not to tighten ahead of the midterm elections could hold back the Fed, as well.
3. However, the Fed's credibility could be in question if it doesn't tighten, particularly since Warsh has emphasized the Fed's intent to bring down inflation. He has said that steady but high inflation is not acceptable. Although the y/y for the Core CPI slipped to 2.4% from 2.5%, it remains above the Fed's 2% target. The uptick in the University of Michigan Survey's 5-year inflation expectations to 3.4% from 3.3%, reported Friday, could add to the concern that the Fed is losing credibility, as could the recent sharp increase in longer-term Treasury yields.
4. Another consideration, away from the latest inflation data, is that the reasons for the 2024-25 rate cuts no longer apply -- /1/ real rates are not higher because inflation fell and /2/ the labor market is not weakening, unlike what appeared to be the case then. Arguably, reversing these cuts could be appropriate. This reason would point to another rate hike later this year even if the Fed hiked this week.
5. In addition, the US economy is being propelled by several independent forces -- AI build-out, defense spending and re-shoring of production. Higher rates are needed to make room for them, given the economy is at full employment. Indeed, as Fed officials like to point out, an AI-caused ratcheting up of productivity growth would require higher market yields. Otherwise, there could be over-investment.
