The apparent calm in the US stock market is concealing deep fractures beneath the surface.
According to the latest report by Morgan Stanley strategist Nick Savone, the S&P 500 Index is just 0.2% away from its all-time high, and its two-week realized volatility sits at the 14th percentile of the past five years, reflecting an unusually tranquil surface.
However, the CCC-rated bond spread has closed above 1,000 basis points, the widest since 2023, and the ratio of CCC to broad high-yield spreads has climbed to a historic peak. This ratio "has historically peaked before even worse credit cycles set in."

Meanwhile, US bank stocks have dropped 13% since August, the 14-day RSI falling to 27, while the S&P 500’s RSI remains above 60. The 33-point gap between the two is the largest in over 30 years.
The above pressures are beginning to permeate broader market pricing logic. The US 10-year Treasury yield rose to 5.30% this week, the highest since 2002, and on Thursday, the 30-year Treasury auction yield set a new high since August 2000. Morgan Stanley maintains its view of two more rate hikes this year, expecting the federal funds rate to reach a range of 4.25% to 4.50%. The bank earnings season kicking off this Tuesday is seen as a key moment to test whether the market can bridge the gap between "fundamental resilience and investor concerns."
Matthew Garman from Morgan Stanley’s European content team noted that US bank stocks have fallen 13% since August, with the BKX index’s 14-day RSI at just 27—deep in oversold territory—while the S&P 500’s RSI has stayed above 60. The 33-point RSI gap between the two is an extreme divergence never seen since 1993. The forward P/E of BKX has dipped back below the near-decade median of about 11.9x.

Beyond rate and oil price factors, the impact of AI-driven trading disruption should not be overlooked in the significant underperformance of bank stocks versus the index.
According to Morgan Stanley prime brokerage data, the financial sector accounts for 10.9% of hedge funds’ North American net exposure, at the 100th percentile over the past year, but only at the 13th percentile since 2010—funds have steadily added bank stocks from a very low base throughout the year, yet the recent 13% pullback is straining new positions.
Morgan Stanley points out that the overall US high-yield spread is at the 16th percentile since 1994, reflecting an apparently loose credit environment; but CCC-rated spreads have broken above 1,000 basis points, up to the 77th percentile, and the CCC-to-broad high-yield spread ratio is at the highest level on record.
Savone points directly to interest rates as the root cause: "The weakest borrowers are beginning to feel the pressure from higher rates and refinancing costs." As high-quality issuers like Broadcom, Oracle, and SpaceX continue large-scale financing at comprehensive yields above 6%, the "crowding out effect" of credit resources is severely limiting the space available to lowest-rated borrowers.
Morgan Stanley’s European derivatives team has begun defensive positioning, recommending protective strategies for a weak-balance-sheet asset basket (MSSTWKBS, covering roughly 50% real estate, highly leveraged industrials, and heavily indebted telecom companies), noting that this basket fell 20% under similar rate shocks in 2022 and currently has realized volatility below the Euro Stoxx 50, making hedging relatively inexpensive.
The macro interest rate environment continues to exert pressure on risk assets.
Morgan Stanley’s cross-asset head Serena Tang notes that the US 10-year Treasury yield rose to 5.30% this week, the highest since 2002; the euro fell to 1.12 against the dollar, reaching a 17-month low. Morgan Stanley’s benchmark metrics show 10-year US Treasury yields, US real yields, and the S&P 500 Index are all at the 100th percentile of their respective ten-year ranges.
Michael Gapen maintains a dovish-hawkish baseline: he characterizes the policy stance as "neutral to mildly restrictive," estimating the true neutral rate has risen from below 100 basis points at the start of 2025 to about 150 basis points, with financial conditions tightening by about 100 basis points since February. Despite September’s weak non-farm payroll figure of just 29,000, he insists the Fed will raise rates 25bps each in December and March, pushing the federal funds rate to a range of 4.25% to 4.50%.
Savone characterizes the upcoming earnings season as a "moment of truth," viewing it as the key window for the market to resolve the divergence between "fundamental resilience and investor anxieties." The market consensus expects S&P 500 third-quarter earnings per share to grow 29.5% year-on-year, with the "Magnificent Seven" tech giants contributing about a quarter of that. Third-quarter EPS forecasts have continued to be revised higher ahead of earnings, with the busiest week being the week of October 26th, when constituents representing 37.3% of the S&P 500’s market cap will report.

However, the high concentration of earnings growth warrants caution.
Morgan Stanley data shows the market’s differentiation of earnings quality is intensifying: For Q2 2025, stocks with both EPS and free cash flow expectations revised higher saw a median next-day gain of 1.7% after reports, while those with EPS revised higher but free cash flow cut dropped an average 0.8%. Chief equity strategist Mike Wilson makes clear that free cash flow and the breadth of estimate revisions will be the core variables determining post-earnings performance.
Early reports show PepsiCo (PEP) slightly beat expectations but cut guidance, triggering concerns over 2027 earnings resets; Constellation Brands (STZ) beat but beer demand and margins remain weak; Levi’s (LEVI) raised its full-year outlook despite revenue slightly missing forecasts; Delta Air Lines (DAL) reported a roughly 16% year-on-year revenue increase for Q3. Savone warns that in an environment where implied volatility for industrials and financials is elevated, the market will reward earnings beats with a premium while being "harsher" on misses.
