What Arch Capital Group Ltd. told the SEC could break it.
Arch Capital's disclosures are entirely regulatory, spanning the breadth of its (re)insurance operations. Its mortgage-insurance business must hold minimum statutory capital against risk in force (in Wisconsin, North Carolina and 14 other states) and build contingency loss reserves of at least 50% of net earned premiums, generally locked for ten years — constraints on writing new business and paying dividends. Its non-U.S. underwriting subsidiaries face the extraterritorial reach of expanding Russia energy-sector sanctions, requiring continual compliance and exposure monitoring. And as a Bermuda-headquartered insurer it is exposed to tax-regime change — the OECD Pillar I/II initiatives and a newly enacted Bermuda corporate income tax, with Pillar II top-up taxes already accrued on certain operations in 2025.

In its own words
What could break it.
Regulatory & policy
- mortgage-insurer statutory-capital and contingency-reserve requirements (WI, NC + 14 states)medium
Arch's mortgage insurance business must maintain minimum statutory capital relative to risk in force (Wisconsin, North Carolina, and 14 other states) and establish contingency loss reserves of ≥50% of net earned premiums generally locked for 10 years — constraints on writing new business and paying dividends.
“Under Wisconsin and North Carolina law, as well as that of 14 other states, a mortgage insurer must maintain a minimum amount of statutory capital relative to its risk in force in order for the mortgage insurer to continue to write new business.”
SEC filing →As of 2026 - economic sanctions (Russia) with extraterritorial reach to non-US underwriting subsidiariesmedium
Expanding sanctions targeting the Russian energy sector (Russian and non-Russian companies, persons, and vessels) may have extraterritorial reach into Arch's non-U.S. underwriting subsidiaries, creating compliance and underwriting-exposure risk that Arch must continually monitor.
“Recent sanctions also target the Russian energy sector, including Russian and non-Russian companies, persons and vessels which are aiding Russia's production of oil. These sanctions may have extra-territorial reach to our non-U.S. underwriting subsidiaries.”
