Why Your HOA Master Policy and HO-6 Keep Climbing in Claim-Free Years

The HOA budget landed in your inbox and the master policy line jumped again. Nobody in the building filed a claim. No hurricane came through. The roof is the same roof it was last year. And still the number the association pays to insure the structure went up, which means your dues go up, which means the check you write every month gets a little heavier for reasons nobody at the annual meeting can quite explain.

Then your HO-6 renewal shows up a few weeks later and does the same thing.

Most condo owners assume this is just cost of claims catching up with them, or general inflation, or bad luck with their carrier. There is a bigger and quieter force at work, and once you understand it, the pattern stops looking random. It is called insurance float, and it is the single most important thing about how your carrier actually makes money that almost nobody ever explains to the people paying the premiums.

You are paying two insurance bills, and both feed the same pool

Every condo owner is really carrying two policies at once.

The first is the HOA master policy. It covers the building structure, the roof, the elevators, the hallways, the shared mechanicals, and usually some portion of your unit's walls depending on how the bylaws are written. You do not write that check directly. It comes out of your monthly dues, and in most associations it is one of the largest line items in the entire budget. If you have ever wondered where your HOA money actually goes, the master policy premium is often near the top of the list.

The second is your HO-6, the individual unit-owner policy. It covers your interior finishes, your personal property, your liability, and your loss assessment coverage. You write that one yourself.

Two separate bills, two separate checks, but the moment either premium is collected it does the exact same thing. It enters a pool the carrier invests immediately. That pool is the float.

What float actually is

When you pay a premium, that money does not sit in a vault waiting for a claim. The carrier collects premiums from thousands of policyholders, and at any given moment a large share of that money has been collected but not yet paid out. That gap, premiums in hand minus claims paid, is the float. The carrier invests it.

For a large insurer, float is measured in tens of billions of dollars. This is not a theory or a metaphor. It is a specific number that shows up in carrier financial statements and regulatory filings.

The clearest example is Berkshire Hathaway, because Warren Buffett has written about it openly for decades in his shareholder letters. As of Berkshire's most recent annual report, its insurance float exceeded $168 billion. That money, collected from policyholders across GEICO and its reinsurance arms, gets invested in stocks, bonds, real estate, and whole businesses. In most years the investment income from those float-funded assets runs above $10 billion, which dwarfs whatever profit or loss the underwriting side produces.

Buffett has called float "better than free." In years when a carrier collects more in premiums than it pays in claims and expenses, policyholders are effectively paying the company to hold and invest their money. And unlike a bank loan that has to be repaid on a schedule, float is continuously refilled. As long as new policies keep getting written, it never has to be paid back in full. It just grows.

Berkshire is the famous case, but every carrier runs on this model. The insurer behind your master policy and the one behind your HO-6 both invest their float the same way. NAIC financial data shows the average property and casualty carrier keeps roughly 60 to 70 percent of its investment portfolio in bonds, another 15 to 25 percent in equities, and a smaller slice in real estate and alternatives. Across the whole industry, the Insurance Information Institute reports that property and casualty carriers have generated something like $80 to $100 billion a year in net investment income in recent years. That is money earned on policyholder premiums, including yours, in the window between collecting them and paying claims.

Why your claim-free building gets almost no credit

Here is where float quietly rewrites the incentives.

Because investment income on the float can rival or exceed underwriting profit, carriers have a strong reason to collect as many premiums as possible. More premiums mean more float. More float means more investment income. Growing the pool matters more than squeezing every claim.

That is why a quiet year at your building barely moves your bill. Your master policy premium is priced off the risk pool the building sits in, its age, roof condition, construction type, location, and the claims history of similar properties, not off whether your specific association filed a claim last year. Your HO-6 works the same way. Some carriers offer a claim-free discount, but it usually runs a trivial 3 to 5 percent, nowhere near enough to offset the base rate increases stacked on top of it. The carrier's real interest is the size of the pool, not your individual behavior. If you want the full picture of how those base rates are moving right now, the 2026 condo rate breakdown lays it out.

Rate increases stick, rate cuts almost never come

NAIC data shows national homeowner insurance premiums have risen every single year since 2014. Not once has the national average dropped year over year, not even in years with below-average catastrophe losses. Float incentives are a big part of why.

When costs climb, from reinsurance hardening, catastrophe losses, or the rising price of the materials needed to repair a building, carriers file for rate increases promptly. When conditions stabilize, they rarely file for decreases, because lower premiums mean a smaller float. NAIC rate filing records show roughly 8 to 12 rate increase filings for every single rate decrease filing across the industry. Regulatory lag makes it worse. Once an increase is approved, it stays in effect long after the conditions that justified it have passed. The ratchet only turns one way.

Interest rates add another layer. When rates are low, as they were from roughly 2009 to 2021, carriers earn less on their bond portfolios and lean harder on premium increases to make up the difference. Higher rates since 2022 should, in theory, ease that pressure because the float earns more. But that improvement got swamped by record catastrophe losses, a hardened reinsurance market, and construction cost inflation. So premiums have kept climbing at roughly 8 to 10 percent a year even while investment conditions got better.

That last point matters for keeping this honest. Float is not a scam, and not every increase on your master policy is greed. Buildings really did get more expensive to rebuild. Reinsurance really did get more expensive to buy, especially for coastal and older structures after high-profile structural failures put a spotlight on aging condos. The float incentive does not invent those costs. What it does is make sure that when the costs ease, your premium does not.

The reinsurance layer sitting on your roof

Your carrier does not hold all the risk on your building by itself. It passes a chunk of it up to reinsurers, companies like Munich Re, Swiss Re, and Hannover Re, that absorb catastrophe losses above a certain threshold. Those reinsurers then tap the capital markets through catastrophe bonds.

Every layer takes a margin. Your dues fund the master policy premium, which funds the carrier's float. The carrier's payment to the reinsurer funds the reinsurer's float. And catastrophe bond investors demand yields, typically SOFR plus 5 to 12 percent depending on the risk tier, to put their capital at risk on storms and quakes. The global catastrophe bond market now exceeds $45 billion in outstanding issuance, according to Artemis, and it has grown enormously since 2010 as pension funds and hedge funds chase returns that do not move with the stock market.

If your building sits in a wind or quake exposed area, that whole chain is priced directly into your master policy. It is worth understanding how catastrophe bonds work and, more specifically, how they thread all the way down to your HOA master policy, because that is often the real reason a coastal building's premium moves in ways the local claims history cannot explain.

What a condo owner can actually watch and do

You cannot opt out of float, and knowing about it will not shrink next year's premium. But it changes what you pay attention to, and a few of those things are within your control.

Read the master policy declarations page at renewal, not just the budget summary. Look at the wind or named-storm deductible specifically. A carrier can hold the headline premium flat while quietly raising that deductible, and a higher master deductible shifts real dollars onto individual owners through loss assessment.

Size your HO-6 loss assessment coverage to the master policy deductible. If the building takes a covered loss and the master policy deductible is large, that shortfall gets spread across every owner. Your HO-6 loss assessment limit is what stands between you and a surprise special assessment, so it should be set with the master deductible in mind, not left at some default number.

Ask the board or manager why the master premium moved. Carriers file rationales with the state insurance department, and boards can request the loss run and the renewal explanation. Sometimes it is genuine building risk. Sometimes it is the reinsurance and float cycle passing through, in which case shopping other carriers may help more than any building repair would.

Shop your HO-6 every year or two, but do not chase the claim-free discount. At 3 to 5 percent it is minor. The bigger levers are your deductible structure, your loss assessment limit, and whether your walls-in coverage actually matches what the master policy leaves to you.

Stop expecting a good year to lower your bill. It almost never does. Budget your dues and your HO-6 on the assumption that both keep drifting up, because the float incentive is built to make sure they do.

None of this makes you immune to the machine. It just means you are reading the same signals the carrier is reading, instead of being surprised by them at the annual meeting.
