<p><b>New page</b></p><div>📈 '''Premium growth rate''' measures the percentage change in an insurer's [[Definition:Written premium | written premiums]] over a defined period, serving as one of the most closely watched indicators of top-line performance across the global insurance industry. Whether tracked on a [[Definition:Gross written premium (GWP) | gross]] or [[Definition:Net written premium (NWP) | net]] basis, this metric captures how effectively a carrier is expanding its book of business through new policy sales, [[Definition:Renewal | renewals]], rate increases, or entry into new lines. Analysts, [[Definition:Rating agency | rating agencies]], and regulators all scrutinize premium growth rate to assess whether an insurer is gaining or losing competitive ground and whether growth is keeping pace with underlying [[Definition:Exposure | exposure]] trends.<br />
<br />
📊 Calculating the rate is straightforward — divide the difference between current-period and prior-period premiums by the prior-period figure — but interpreting the result requires nuance. Growth driven primarily by [[Definition:Rate hardening | rate increases]] in a hardening market tells a different story than growth fueled by volume expansion into untested segments. Organic growth, which excludes the effect of [[Definition:Merger and acquisition (M&A) | acquisitions]] or portfolio transfers, is often isolated to give a cleaner picture of underlying momentum. In markets governed by [[Definition:Solvency II | Solvency II]] or [[Definition:Risk-based capital (RBC) | risk-based capital]] frameworks, rapid premium growth can trigger additional [[Definition:Capital adequacy | capital adequacy]] scrutiny, since expanding the book faster than reserves and surplus can support raises solvency concerns. Similarly, Japan's Financial Services Agency and China's [[Definition:C-ROSS | C-ROSS]] regime both factor growth trajectories into their supervisory assessments.<br />
<br />
🔍 Understanding premium growth rate in context is essential because raw numbers can mislead. A carrier posting double-digit growth may be [[Definition:Underpricing | underpricing]] risk to buy market share — a strategy that often ends in [[Definition:Loss reserve | reserve]] deficiencies and deteriorating [[Definition:Combined ratio | combined ratios]]. Conversely, flat or negative growth during a [[Definition:Soft market | soft market]] may reflect disciplined [[Definition:Underwriting | underwriting]] rather than competitive weakness. [[Definition:Insurtech | Insurtech]] ventures and [[Definition:Managing general agent (MGA) | MGAs]] often exhibit exceptionally high growth rates in early years, which investors evaluate alongside [[Definition:Loss ratio | loss ratio]] development to judge sustainability. For [[Definition:Reinsurance | reinsurers]], monitoring ceding companies' premium growth rates helps flag potential shifts in portfolio composition that could affect treaty performance.<br />
