The ‘Golden Age‘-20260714
摩根士丹利· 2026-07-14 21:13
July 14, 2026 12:01 PM GMT Refiners | Asia Pacific The "Golden Age" Fuel markets have weathered three shocks in six years and emerged stronger each time. We see more legs to our bullish fuel refining cycle view. Asian refiners should enjoy a new higher mid-cycle - the market overestimates new capacity addition and underestimates disruption to existing capacity. Key Takeaways Go Refining! The Refining Golden Age we expected in 2018, has got stronger in the last six years. Fuel consumption has risen 1.4x fast ...

While the stock has corrected by 36% (-43% vs TAIEX) after the 1Q26 gross margin miss, we view the margin pressure as largely transitory ...

US Economics The Daily Update - From Waller to Warsh CITI'S TAKE Yesterday Governor Waller hawkishly said that a "hot" inflation reading today could lead to a "near-term" rate hike. Chair Warsh may decline to walk this back in congressional testimony today given his desire to give no forward guidance. But we expect a "cool" 0.19%MoM core CPI reading and see rate hikes this year as unlikely. In our base case the next Fed move is a cut.
