Red Sea Container Shipping: Analyzing "Re-entry" Through Multiple Interpretations

Executive Summary

The question of whether container ships have "re-entered" the Red Sea depends entirely on how one defines "re-entry." The data from November 2023 through September 2025 supports different conclusions based on different reasonable interpretations:

• Never fully left: Some container ships maintained operations throughout the crisis
• Partial recovery occurred: Traffic doubled from January 2024 lows by summer 2024
• Major carriers remain absent: All major shipping lines continue avoiding the route
• Volume remains severely depressed: Current traffic sits at ~40% of pre-crisis levels

Crisis Timeline and Recovery Trajectory

November 2023 - January 2024: The Collapse

The crisis began with Houthi attacks escalating from November 19, 2023. By December 17, 2023, all major container lines (Maersk, MSC, CMA CGM, Hapag-Lloyd, etc.) suspended Red Sea transits. Container traffic through the Suez Canal plummeted from over 100 vessels daily to its lowest point in January-February 2024, when deep-sea port calls in the Red Sea dropped 85%, from over 200 monthly calls to under 40.

February - June 2024: The Trough

Container traffic stabilized at approximately 15-20% of pre-crisis levels. CMA CGM attempted limited returns on February 28, 2024, becoming the first major carrier to test Red Sea transits with naval escorts, though this remained highly selective and most vessels continued Cape of Good Hope diversions.

Summer 2024: Partial Recovery

July 2024 marked a turning point with traffic doubling to 60 deep-sea port calls (about 30% of pre-crisis levels). Sub-Panamax vessels under 4,000 TEU began consistently recording over 100 crossings monthly from August onward. This recovery was highly segmented by vessel size.

Late 2024 - September 2025: Stabilized Depression

Traffic stabilized at approximately 40% of pre-crisis levels. The November 2024 "high" of 54 container vessels per week remained far below normal operations. All major carriers maintained their Red Sea avoidance policies through September 2025.

Vessel Size Segmentation Shows Divergent Recovery

The recovery pattern varies dramatically by vessel size, complicating any simple "yes/no" assessment:

• Sub-Panamax (<4,000 TEU): 70-80% recovery, now comprising 78% of all traffic
• Mid-sized (4,000-7,500 TEU): Modest recovery from 2024 lows
• Large vessels (7,500-18,000 TEU): 92.5% decline, less than 20 passages monthly
• Ultra-large (>18,000 TEU): Complete absence for 9+ months

Interpretation Options for "Re-entry"

Interpretation 1: "Any container ship traffic"

Resolution: YES - Ships re-entered

• Container ships never completely stopped transiting
• Even at the lowest point, some vessels maintained operations
• Traffic increased from winter lows by summer 2024

Interpretation 2: "Return to normal operations"

Resolution: NO - Ships have not re-entered

• Current traffic remains 60% below pre-crisis levels
• Major shipping lines maintain indefinite suspensions
• Ultra-large vessels completely absent

Interpretation 3: "Major carriers resuming service"

Resolution: NO - Ships have not re-entered

• Maersk, MSC, and others continue avoiding the route
• CMA CGM's February 2024 attempt was limited and temporary
• No major carrier operates regular Red Sea schedules

Interpretation 4: "Reaching 50% of pre-crisis volume"

Resolution: NO - Ships have not re-entered

• Peak 2024 recovery reached only ~40% of pre-crisis levels
• October 2024 traffic was 57% below previous peaks
• Current operations remain below half of normal capacity

Interpretation 5: "Meaningful commercial resumption"

Resolution: Ambiguous

• Depends on definition of "meaningful"
• Small vessels show meaningful recovery (70-80%)
• But absence of large vessels undermines commercial viability
• Industry consensus: current state is "new normal" not resumption

Interpretation 6: "More traffic than crisis low point"

Resolution: YES - Ships re-entered

• Traffic doubled from January-February 2024 lows by July 2024
• Sustained improvement maintained through 2025
• Clear upward trajectory from absolute bottom

Key Metrics by Summer 2024

The Manifold market's specific reference to "summer" provides a temporal benchmark:

By July-August 2024:

• Deep-sea port calls: 60 per month (vs. 200+ pre-crisis)
• Percentage of normal: ~30%
• Trend direction: Recovering from 15-20% lows
• Major carriers present: None
• Small vessel recovery: Beginning to strengthen

Industry Perspective on "Re-entry"

Maritime industry sources provide context for interpretation:

• Lloyd's List (September 2025): "No recovery for Red Sea traffic"
• Sea-Intelligence: Characterizes current levels as "new normal" rather than recovery
• Drewry Maritime: 54% of stakeholders hope for resumption by end-2025 (indicating it hasn't happened yet)
• Shipping associations: Call for continued military protection, indicating ongoing crisis

Factors Supporting Different Resolutions

Supporting "YES" (ships re-entered):

• Container traffic never fully ceased
• Clear recovery from 15-20% to 30% by summer 2024
• Smaller vessels maintained consistent operations
• Some regional/feeder services continued throughout

Supporting "NO" (ships haven't re-entered):

• No major carrier has resumed normal Red Sea service
• Volume remains below 50% of pre-crisis levels
• Insurance costs remain prohibitive (10-40x normal)
• Ultra-large vessels completely absent
• Industry doesn't consider this "recovery"

Conclusion: Resolution Depends on Definition

The data clearly shows container ships partially returned to the Red Sea by summer 2024, but whether this constitutes "re-entry" depends entirely on the threshold applied. The market creator's lack of specific criteria leaves multiple reasonable interpretations:

• Minimalist interpretation: YES - any increase from lowest point counts
• Industry standard interpretation: NO - major carriers haven't returned
• Volume-based interpretation: NO - remains below 50% of normal
• Pragmatic interpretation: PARTIAL - small ships yes, large ships no

Without explicit resolution criteria, this market essentially asks traders to predict the creator's subjective interpretation rather than an objective outcome. The evidence supports either resolution depending on which reasonable definition of "re-entry" is applied.
