Specialist Insurance Is a Claim Most Firms Can't Back, Says Accredited CEO

Accredited's McMurdo: What a 'Specialist' Insurer Actually Looks Like

Almost every London market insurer calls itself a specialist. Stuart McMurdo, chief executive of Accredited Insurance (Europe & UK), argues that far fewer can actually explain why.

McMurdo, who joined Accredited in October 2024, runs a business that is “entirely dedicated to MGA” — a managing general agent platform, rather than a specialty carrier that happens to write MGAs. The company writes around $2 billion in gross written premium, split evenly between the UK/Europe and the US, with about 100 employees in each region. After completing a portfolio remediation programme, Accredited has shifted capital away from legacy books and into areas it believes offer stronger long-term returns.

For McMurdo, genuine specialism has little to do with writing marine, engineering, fine art or any other traditional specialty class. It is about holding an advantage competitors cannot easily replicate — a geographic market position, a distribution network or a risk-management capability that produces market-beating results. “When you press a little, you’ll find out that they haven’t really thought it through,” he said of firms that use the specialist label without defining it.

He links long-term survival to underwriting discipline: winners “don’t write risks that they don’t understand,” and investors must have the courage to accept slower growth when conditions do not reward expansion. McMurdo also sees capacity crowding in transactional liability lines such as warranty and indemnity, contingency and tax, where WR Berkley has already reduced exposure, and points to political violence as an area now “on the move” after the Middle East conflict, while warning that fresh capital could quickly recreate the same competitive pressure. The firms that emerge strongest, he expects, will sacrifice short-term growth to protect underwriting standards.

The Underwriting Clock, Crowded Capacity and the Political Violence Opportunity

McMurdo’s comments read as a challenge to the marketing side of specialty insurance. In a market where “specialist” has become a default label, his test is concrete: a firm should be able to name a distribution, geographic or risk-management advantage that shows up in results. By that measure, a plain line operated with a genuine edge counts as specialism, while a niche line operated without one does not.

Accredited is making a structural bet on the pure MGA model

The company’s positioning matters as much as its words. With roughly $2 billion in GWP split evenly between the UK/Europe and the US and about 100 employees on each side, Accredited is not a large carrier; its claim to distinction is that it is entirely built around MGA underwriting. The completed portfolio remediation programme and the reallocation of capital away from legacy books reinforce the same message: management wants to be judged on the quality of the risks it keeps, not on the breadth of the book.

The underwriting clock puts shareholder patience in the spotlight

McMurdo’s reference to the “underwriting clock” — a market-cycle framework from the early 1980s — is a reminder that the MGA sector has seen this pattern before. In a softening market, the pressure to hit annual growth targets builds inside the business; his argument is that the binding constraint is usually not the underwriters but the investors behind them. If shareholders insist on year-on-year expansion, underwriting standards tend to bend. That is why he frames the winners as the firms whose owners allow them to “tap off” growth when pricing does not justify it.

Transactional liability shows how a line gets crowded — political violence may be next

The contrast between transactional liability and political violence is the most concrete part of the interview. Transactional liability — warranty and indemnity, contingency and tax risks — has attracted enough capacity that WR Berkley has reduced exposure; McMurdo treats it as a market where discipline is already being tested. Political violence, by contrast, is “on the move” in the wake of the Middle East conflict, and accumulation risk has moved into the spotlight. His warning that fresh capital could eventually create the same pressures elsewhere is, in effect, an acknowledgment that today’s opportunity can become tomorrow’s crowded line. Other MGA leaders have made a parallel point: underwriting expertise, not access to capacity, is becoming the real differentiator in specialty insurance.

What MGA Leaders Can Do Before the Cycle Turns

McMurdo’s argument gives MGA leaders and their investors a practical checklist before the cycle turns further.

• Write down the actual advantage. He says many firms that call themselves specialists cannot explain the distribution, geographic or risk-management edge behind the label. If the advantage cannot be stated in one sentence, it is probably not a durable one.
• Test whether growth targets override underwriting standards. McMurdo links annual growth pressure to decisions to write risks the team does not fully understand. Review incentive structures and give underwriters explicit permission to decline business when pricing is inadequate.
• Audit wordings for coverage drift. His warning about terms and conditions changing “all of a sudden” producing unexpected claims is a direct reason to compare current policy wordings with original underwriting intent.
• Reassess crowded lines such as transactional liability. WR Berkley has already trimmed exposure in W&I, contingency and tax risks; firms still writing those classes should stress-test rates and limits against the new capacity.
• Build the political violence book with the next cycle in mind. The line is “on the move” after Middle East escalation, but McMurdo expects fresh capital to arrive. Underwrite accumulation risk now rather than chasing the top of the market.
