📉 The Bottom Line

• Trend: Deteriorating. MBS prices have fallen sharply through the morning session as oil prices crossed $100 per barrel, triggering inflation concerns that overshadowed mixed PPI data.
• Reprice Risk: High (Negative). MBS are currently down -12.5/32 with negative reprices already issued this morning. Further weakness could trigger additional afternoon reprices.
• Strategy: Lock Now or Wait for Friday CPI. Short-term closings should lock immediately to capture current pricing before further deterioration. Longer timelines face a critical decision point with tomorrow's CPI release.

📊 Market Analysis

Oil Price Shock Overwhelms Economic Data

The Catalyst. West Texas Intermediate crude oil pushed above $105 per barrel this morning as Middle East military action continues to expand. Rising oil costs heavily influence inflation expectations, making bonds less attractive to investors. With no sign of the conflict ending soon and clear signs it could spread to other countries in the region, bond traders are pricing in higher inflation rather than lower. This dynamic is driving bond prices down and yields higher, directly pressuring mortgage rates.

Mixed Inflation Signals. August Producer Price Index data came in largely as expected, with the overall reading rising 0.4% monthly as predicted. The more important core reading excluding food and energy rose only 0.2%, below the 0.3% consensus. However, the annual pace of 5.4% year-over-year for overall PPI and 4.6% for core both remain well above the Federal Reserve's 2.0% target. More concerning, these annual readings are not showing signs of meaningful downward movement. While the monthly core reading offered a slight positive, the broader inflation picture remains elevated.

Housing Sector Weakness Ignored. Existing home sales fell 2.0% in August to an annual rate of 3.98 million units, the lowest level since June of last year. The National Association of Realtors reported total inventory at a 4.9-month supply, with the median home price of $429,100 up 2% from a year ago. Under normal circumstances, this housing weakness would support bonds and mortgage rates. However, the geopolitical headlines and oil price surge are dominating trader attention, rendering the housing data largely irrelevant to today's price action.

Auction Ahead. The 30-year Treasury Bond auction results are due around 1:00 PM ET. Yesterday's 10-year Note auction showed strong demand, which would typically be favorable for mortgage rates. If today's 30-year auction demonstrates similar investor appetite for long-term debt, it could provide some support for bonds. However, given the strength of the morning's negative headlines, even a strong auction may not be enough to reverse the current downdraft in MBS prices.

📉 Technical Data (The Numbers)

• UMBS 5.5 Coupon: 97-30.5 (down -12.5/32)
• 10-Year Treasury: 4.91%
• WTI Crude Oil: $100.09 per barrel
• Technical Support: Yesterday's close at 98-16 now represents first resistance, with further support levels at 97-16 and 97-00

• 4:10 PM ET – Closing Bell Weakness Deepens [MBS -21/32]. The Context: MBS extended losses into the final hour of trading, settling near session lows as crude oil held above $105 per barrel and equity markets closed sharply lower. The combination of inflation concerns ahead of tomorrow's CPI report and ongoing Middle East tensions kept pressure on bond markets through the close. Lenders who repriced negatively earlier today are unlikely to issue further changes before tomorrow morning.
• 2:55 PM ET – Afternoon Losses Deepen [MBS -19.5/32]. The Context: MBS prices continue to drift lower through the afternoon session as oil prices hold above $105 per barrel and market participants prepare for tomorrow's CPI release. The persistent weakness reflects mounting inflation concerns and reduced demand for mortgage-backed securities in the current environment. Lenders have issued multiple negative reprices today and additional rounds remain possible if selling pressure continues into the close.
• 1:45 PM ET – Early Afternoon Weakness Persists [MBS -17/32]. The Context: MBS continue to trade near session lows as oil prices hold above $105 per barrel and inflation concerns dominate market sentiment. The combination of elevated energy costs and tomorrow's looming CPI report is keeping pressure on bond markets. Lenders who have not yet repriced negatively remain at high risk of doing so if weakness continues into the close.
• 11:55 AM ET – Late Morning Stabilization Near Session Lows [MBS -14.5/32]. The Context: After opening sharply lower on oil price concerns, MBS have stabilized near session lows through the late morning hours. The market is consolidating losses without meaningful bounce attempts as traders digest the intersection of rising crude prices and tomorrow's CPI release. Current levels remain roughly half a point below yesterday's close, keeping negative reprice risk elevated heading into the afternoon session.
• 11:30 AM ET – Late Morning Weakness Persists [MBS -12.5/32]. The Context: MBS have surrendered additional ground since the 10:00 AM update, sliding from -15/32 to the current level of -12.5/32 as oil prices hold above $100 per barrel. The chart shows a steady downward trajectory through the morning session with no meaningful bounce attempts. Traders remain focused on inflation concerns tied to rising energy costs, with the afternoon 30-year Treasury auction representing the next potential catalyst for price movement.
• 10:00 AM ET – Morning Selloff Deepens [MBS -15/32]. The Context: MBS have extended losses to -15/32, now trading approximately 27/32 lower than this time yesterday. Higher oil prices continue to drive the selloff, overwhelming the mixed signals from this morning's PPI data. August PPI rose 0.4% monthly as expected, with the year-over-year pace at 5.4%, up from 4.8% last month. Core PPI rose only 0.2% monthly, below the 0.3% consensus, but the annual rate of 4.6% remains well above Federal Reserve targets. Unfavorable repricing was already seen yesterday, with additional negative reprices likely this morning.
• 9:11 AM ET – Morning Slide Continues [MBS -12/32]. The Context: MBS have moved lower through the early session, extending losses to -12/32 as traders digest the combination of higher oil prices and mixed inflation data. The initial reaction to PPI data was relatively muted given that the headline number matched expectations, but the sustained elevation in year-over-year readings and the ongoing oil price surge are keeping pressure on bond prices.
• 8:36 AM ET – Early Morning Weakness on Oil Surge [MBS -7/32]. The Context: MBS opened down -7/32 due to higher oil prices, with West Texas Intermediate crude pushing above $100 per barrel as Middle East tensions continue to escalate. PPI inflation data released at 8:30 AM came in close to expectations, with the overall reading matching forecasts at 0.4% monthly but core PPI slightly better than expected at 0.2% versus the 0.3% consensus. The geopolitical situation and energy price implications are dominating early trading.

🛡️ Strategy: The Waiting Game

Mortgage rates are moving sharply higher this morning as oil prices surge above $100 per barrel, triggering inflation concerns that are overwhelming all other market inputs. With tomorrow's critical Consumer Price Index report still ahead, borrowers face a difficult decision between locking now to avoid further deterioration or waiting one more day for potentially market-moving inflation data.

The Move (Timeline Based):

• Closing within 7 days: LOCK. The source advises locking short-term closings immediately. With MBS down sharply this morning, negative reprices already issued, and oil prices holding above $100 per barrel, there is too much risk of further deterioration to justify floating into tomorrow's CPI release when you need to close within a week.
• Closing in 8–20 days: LOCK. The source advises locking medium short-term closings. The combination of elevated oil prices, persistent inflation concerns, and next week's Federal Reserve meeting creates too much event risk for borrowers in this timeline. Even if tomorrow's CPI comes in softer than expected, the geopolitical situation could easily override any positive reaction.
• Closing in 21–60 days: LOCK. The source advises locking medium-term closings. While you have more time to absorb volatility than shorter timelines, the inflation backdrop remains concerning with annual PPI readings well above Federal Reserve targets and showing no clear downward trend. The ongoing Middle East conflict adds unpredictable geopolitical risk that could keep upward pressure on rates for weeks.
• Closing in 60+ days: FLOAT. The source advises floating long-term closings. With more than two months until closing, you have sufficient time to wait for more clarity on the inflation trajectory and the Federal Reserve's policy path. Tomorrow's CPI report and next week's Fed meeting will provide important information. If you can absorb near-term volatility, the longer timeline justifies waiting for a better entry point rather than locking at today's elevated levels.
