The renewal notice arrives. The premium is going up, perhaps by 20 per cent, perhaps by more. The explanation in the letter is medical inflation. That is partly accurate. It is rarely the complete picture.
For most Singapore SME employers, the renewal conversation starts and ends with the number. Understanding what produced the number is where the more useful conversation begins.
What a claims ratio is and why it drives your renewal premium
At each renewal, your group medical insurer assesses the loss ratio for your group across the prior policy period. The loss ratio is the total value of claims paid out as a proportion of the total premiums collected from your group.
For most SME group medical plans in Singapore, the threshold that triggers repricing sits between 65 and 75 per cent, according to market practice. A group that has stayed below that threshold may see a modest increase reflecting age-adjusted repricing and medical inflation. A group that has crossed it will see repricing that reflects the actual claims experience.
The renewal letter shows the new premium. The inputs that produced it, your group's loss ratio, the age profile movement, and the insurer's own portfolio performance, are in the underwriter's file. Most SME employers never see those inputs unless they ask for them.
Asking for the claims ratio before the renewal conversation is the starting point. You cannot negotiate or plan a response to a number whose origins you have not seen.
The factors that drive your claims ratio up
Four inputs drive the group medical premium at renewal. Understanding each one tells you what is within your control and what is not.
Age profile movement. Group medical insurance premiums are priced on the age profile of the insured group. As your workforce ages, the premium increases to reflect higher statistical healthcare utilisation. This movement happens every year regardless of claims. A team that has grown older by an average of one year since last renewal carries a higher age-adjusted base premium before any claims adjustment is applied.
For most SMEs, age profile movement is not tracked year on year. The gap between this year's premium and last year's is attributed entirely to market conditions when in fact a portion of it reflects the demographic shift of the same workforce.
Claims experience. A single large inpatient claim in a small group can move the loss ratio above the repricing threshold on its own. In a group of 20 employees, one hospitalisation costing S$30,000 against a total annual premium pool of S$80,000 produces a loss ratio of 37.5 per cent on that claim alone. Add routine outpatient claims and the group's full-year loss ratio can cross the 70 per cent threshold without any systematic over-utilisation.
This is the part that feels unfair to most employers, and in a narrow sense it is. An employee with a serious illness is not behaving wrongly by claiming. But the insurer is also not behaving wrongly by repricing a group whose claims experience has crossed the threshold. Both things are true simultaneously.
Benefit structure. The level of cover the group holds directly determines the base cost and the claims ceiling. A group with private ward entitlement, comprehensive outpatient cover, and high sub-limits has a higher base premium and a higher potential claims pool than a group with B1 entitlement and panel-only outpatient cover.
Insurer portfolio performance. The insurer's overall claims experience across their full group medical portfolio affects pricing across all groups, including yours. In a year of high industry-wide healthcare utilisation, all groups see some upward pressure regardless of their individual experience.
What you can actually do about it
Of the four inputs above, the employer has meaningful influence over two: the benefit structure and, indirectly, the claims pattern through the choices the group makes about when and how to seek care.
Review the benefit structure before renewal. The most direct lever on premium is the benefit level. A group that moves from private ward to A class ward entitlement, or that introduces a co-payment on outpatient visits, will see a reduction in both the base premium and the claims pool. The trade-off is that the benefit becomes less generous. Whether that trade-off is appropriate depends on what the group actually uses.
A useful step before renewal is reviewing the actual utilisation pattern of the current benefits. If 80 per cent of claims are outpatient GP visits and the inpatient benefit is rarely used, the benefit structure may not be optimised for what the group actually needs. A restructure that reduces unused headroom and directs spend toward what the group actually uses can reduce cost without reducing experienced value.
Confirm your panel clinic arrangement. Outpatient claims from non-panel visits cost more than panel visits. A group where employees routinely visit non-panel clinics because the panel is inconvenient or poorly communicated is generating higher outpatient claims than the panel arrangement is designed to produce. Reviewing the panel network and communicating it clearly to employees reduces avoidable cost at the margin.
Consider a co-payment structure. A co-payment, where the employee pays a fixed amount per GP visit or per outpatient claim, reduces the volume of low-value claims and introduces a natural check on utilisation. Most employees do not dramatically change their healthcare behaviour based on a S$10 co-payment on a GP visit. But the co-payment signal changes the utilisation pattern at the margin, and the removal of zero-cost outpatient access reduces the volume of discretionary visits.
Introducing a co-payment requires communication to employees and careful framing. It is a reduction in a benefit that employees have come to expect, and it needs to be explained clearly as part of a sustainable programme rather than as a cost-cutting measure.
Understand what the insurer's data says. At renewal, an employer is entitled to ask for the claims data for their group. This typically includes the total premium collected, the total claims paid, the loss ratio, and in some cases a breakdown of claims by category. This data is the basis of the renewal quote. Reviewing it before the renewal conversation tells you whether the premium increase reflects genuine claims experience or general market loading, and it gives you a basis for discussing the renewal terms with the insurer through your adviser.
When to consider switching insurers
A high loss ratio renewal may prompt the employer to consider switching to a different insurer who will quote a lower premium. This is sometimes the right decision and sometimes a decision that creates more problems than it solves.
A new insurer quoting a lower premium on a group with a high loss ratio is underwriting that group on assumed rather than actual experience. At the first renewal with the new insurer, when their actual claims data is available, the repricing may be significant. The employer has deferred the repricing by one year, not avoided it.
There are also practical continuity considerations when switching insurers mid-programme. We cover these in detail in our post on Switching Your Group Medical Insurer at Renewal.
