Despite the tensions of war, ex-Barclays CEO Bob Diamond is long Gulf. Here’s why

Panmure Liberum is opening its first regional office in Bahrain to serve mid-market and family-owned businesses across the Gulf Cooperation Council; the advisory firm has more than 250 U.K.-listed company clients. The expansion comes as U.K. deal activity fell 13% in the first half of 2026 year over year, according to PwC, while Bob Diamond described business activity in the Gulf as continuing despite regional conflict. Diamond also cited opportunities for stablecoin payments and blockchain-based settlement, but the article reports no market reaction.

Analysis

The investable signal is a possible shift in where mid-market advisory capacity and financial infrastructure are built—not evidence that Gulf deal activity is insulated from conflict. Panmure Liberum is privately held, so its expansion does not directly create earnings exposure for Morgan Stanley (MS) or Goldman Sachs (GS); if sustained, however, it could intensify competition for regional mandates and talent while giving local businesses another route to capital. The more important near-term constraint is whether security risk raises execution, insurance, or funding costs enough to delay transactions.

Mastercard’s (MA) expanded B2B payments arrangement is strategic optionality, not yet proof of material revenue. Dollar-linked stablecoin settlement could lower costs for some cross-border flows, but could also bypass card networks; the outcome depends on whether MA supplies compliant settlement infrastructure or loses transaction economics to new rails. The announcement alone does not resolve that question. The Bahrain mill expansion is tied to Olayan Kimberly-Clark, so any benefit to Kimberly-Clark Corporation (KMB) should be treated as subsidiary-level until capacity, ownership economics, and consolidated financial impact are verified.

Contrarian risk: conference optimism and visible investment announcements can coexist with delayed or cancelled deals if Iran-related tensions escalate. Over the next 1–3 months, track transaction completions, regional security developments, and MA’s disclosed B2B volumes; over 6–18 months, watch stablecoin regulation and actual adoption. No direct earnings trade is justified on this evidence alone.

Key Decisions for Investors

• MA: Keep on a watchlist rather than add on the announcement. Reassess if Mastercard discloses sustained B2B payment volumes or revenue contribution; downgrade the thesis if compliant stablecoin rails gain share while MA is absent from settlement economics.
• KMB: Do not extrapolate the mill expansion into a consolidated earnings upgrade. Verify the facility’s ownership, planned capacity, investment, and expected contribution in company disclosures before positioning.
• MS/GS: No immediate relative-value trade. Monitor whether Gulf mandate wins become recurring and large enough to affect reported advisory results; a sustained increase in regional deal completions would strengthen the competitive-pressure thesis.
• Risk trigger: Revisit any Gulf-growth exposure if conflict escalation materially disrupts business operations or transaction execution. The key falsifier for the resilience narrative is a visible pullback in completed deals, not conference attendance or announced intentions.
