The Underwriting Cycle: Why Your Insurance Premiums Move and How to Use That to Your Advantage

If you have been buying insurance for any length of time, whether for a vessel, a cargo program, or a commercial operation, you've noticed that premiums do not move in a straight line. Some years the market feels competitive, underwriters are flexible, and capacity seems abundant. Other years the same coverage costs significantly more, terms tighten, and underwriters who were previously eager for your business become selective or absent entirely. This is not arbitrary. It is the underwriting cycle, and understanding how it works is one of the most practically useful things a sophisticated insurance buyer can do.

What the Underwriting Cycle Is

The underwriting cycle, also called the insurance market cycle, describes the recurring pattern of expansion and contraction in insurance market capacity, pricing, and terms. It alternates between two primary phases: the hard market and the soft market. These phases are driven by the interplay of underwriting losses, investment returns, capital flows into and out of the insurance industry, and large-scale loss events that reshape the market's view of risk.

The cycle is not unique to any one line of insurance. It operates across marine, property, casualty, liability, and specialty lines, though different segments of the market move at different speeds and are affected by different triggers. A catastrophic hurricane season may harden property markets while marine hull rates remain relatively stable. A surge in maritime casualties or a geopolitical crisis that generates mass war risk claims, as we have seen in the Gulf over the past several months, can harden marine markets while commercial property pricing holds flat. Understanding which phase of the cycle your specific lines of coverage are in at any given time is the starting point for intelligent purchasing decisions.

The Hard Market

A hard market is characterized by rising premiums, tightening terms and conditions, reduced capacity, and increased underwriter selectivity. Insurers in a hard market have pricing power, they can decline risks they consider marginal, impose higher deductibles, narrow coverage terms, and charge more for the same coverage that was available more cheaply in prior years.

Hard markets are typically triggered by one or more of the following: a period of underwriting losses that has eroded insurer and reinsurer capital bases; a major catastrophic loss event or series of events, a natural disaster, a geopolitical crisis, a surge in large claims, that causes the market to reassess its aggregate exposure; a reduction in investment returns that removes the subsidy that investment income provides to underwriting results; or the withdrawal of reinsurance capacity that forces primary insurers to retain more risk and price accordingly.

The marine market has been through a pronounced hard market period in recent years. War risk premiums in the Red Sea and Persian Gulf have reached levels not seen in decades, driven directly by the geopolitical disruptions discussed in prior posts on this site. The broader marine hull and cargo markets also experienced significant hardening following a period in the late 2010s during which underwriters absorbed sustained losses while investment returns remained suppressed. The correction was overdue and its effects are still being felt in parts of the market.

For insurance buyers in a hard market, the strategic options are limited but not zero. This is the time to demonstrate the quality of your risk: clean loss history, robust risk management practices, accurate and complete underwriting submissions, and a willingness to engage in dialogue with underwriters rather than simply seeking the lowest quote. Underwriters in a hard market are allocating capacity selectively, and the risks that present themselves as well-managed, well-documented, and commercially straightforward will access better terms than those that do not. It is also a time to resist the temptation to reduce coverage in response to higher premiums. The hard market environment that is generating higher costs is often the same environment in which claims are more likely to materialize.

The Soft Market

A soft market is characterized by falling premiums, broadening coverage terms, increased capacity, and growing underwriter competition for premium income. In a soft market, insurers are willing to accept risks they might decline in harder conditions, deductibles trend downward, policy language becomes more favorable to insureds, and new capacity competes aggressively for market share.

Soft markets develop when the industry has accumulated significant surplus capital, typically following a period of profitable underwriting and strong investment returns, and when the absence of major loss events has kept claims experience benign. Capital that might otherwise find higher returns elsewhere flows into the insurance market, capacity expands, and competitive pressure drives pricing down. This continues until the market reaches a point where pricing is insufficient to cover expected losses, at which point a triggering event, or simply the accumulated weight of inadequate pricing, tips the market back toward hardening.

The current London cargo insurance market is operating in broadly soft conditions. Available capacity now exceeds $1.5 billion, pricing is competitive across most commodity sectors and trade lanes, and terms are largely favorable to buyers. This is partly a function of accumulated market capital and partly a reflection of the fact that cargo underwriting, outside of the war risk segment specifically affected by Gulf disruption, has not experienced the kind of sustained loss pressure that would justify significant rate increases. For buyers of cargo coverage, this is a favorable purchasing environment.

The Reinsurance Connection

One aspect of the underwriting cycle that insurance buyers rarely consider but should understand is the role of the reinsurance market. Reinsurance is insurance for insurers. Primary underwriters purchase reinsurance to protect their own capital against large individual losses and aggregate loss scenarios. The price and availability of reinsurance directly affects the price and availability of primary insurance, because the cost of reinsurance is a component of the primary underwriter's expense base.

When reinsurance capacity tightens, as it does following major loss events that generate large reinsurance claims, primary insurers face higher reinsurance costs, which flow through to higher primary premiums. The converse is equally true: abundant reinsurance capacity at competitive pricing enables primary insurers to write more business at lower rates. The January 1 reinsurance renewal season, when the majority of global reinsurance treaties are placed, is the most important annual indicator of where primary insurance pricing is likely to move in the following year. Buyers who pay attention to reinsurance market commentary at the start of each year are better positioned to anticipate premium movements in their own programs.

How to Use the Cycle as a Buyer

The underwriting cycle creates distinct strategic opportunities and risks for insurance buyers depending on which phase the market is in. Treating it passively, renewing your program at whatever rate your broker presents without reference to market conditions, is a significant missed opportunity in a soft market and a costly mistake in a hard one.

In a soft market, the strategic priority is program restructuring rather than simply taking the cheapest available quote. When capacity is abundant and underwriters are competing for your premium, this is the time to broaden your coverage terms, reduce deductibles, address gaps in your program that were unaffordable or unavailable in harder conditions, and lock in multi-year agreements where the underwriter is willing to offer them. A soft market is also the time to consolidate your program, moving fragmented coverages to a smaller number of carriers who can offer broader terms and more responsive claims handling in exchange for a larger share of your premium.

In a hard market, the priority shifts to relationship management and risk presentation. Underwriters in a hard market are rationing capacity, and the buyers who receive the best terms are those with whom underwriters have an existing relationship and whose loss history they understand. If you have not built those relationships during the soft market, through consistent placement with the same markets, prompt and transparent claims notification, and accurate underwriting submissions, you will find yourself competing for capacity at the margin when the market hardens. The time to build underwriter relationships is when you do not urgently need them.

For operators across both marine and commercial lines, there is a further consideration that is frequently overlooked: the cycle does not move uniformly across all lines. It is entirely possible, and in fact common, for a buyer to be renewing a marine hull program in a hard market while their commercial property renewal is in soft conditions, or vice versa. Managing your insurance program as an integrated whole, with awareness of where each line sits in its respective cycle, allows you to allocate your risk management budget toward the lines where coverage restructuring is most valuable at any given moment.

The Current Picture

As of mid-2026, the market is split. War risk and marine liability lines touching the Persian Gulf and Red Sea corridors are in pronounced hard market conditions; premiums remain elevated, terms are restrictive, and some underwriters have withdrawn capacity from those trades entirely. The disruption in the Gulf has created exactly the kind of large-scale, concentrated loss environment that hardens specific market segments while leaving others largely unaffected.

Outside of those war risk segments, the broader marine cargo market is soft, London capacity is competitive, and terms are generally favorable to buyers. Commercial lines (general liability, property, and professional lines) are in a mixed environment that varies significantly by class and geography, with property catastrophe-exposed lines remaining firm in loss-affected regions while other commercial lines have seen gradual softening.

The practical implication for Nord Young clients is straightforward: if your program includes war risk coverage for Gulf trades, now is the time to ensure your coverage structure is correct and your limits are adequate, not to seek cheaper alternatives that may leave gaps. If your program includes cargo or commercial lines coverage outside the war risk segment, this is a favorable moment to review your terms and consider whether a soft market environment can be used to address coverage gaps or restructure your program on better terms than were available two or three years ago.

That conversation is exactly what Nord Young is here to have.
