Catalytic converter theft in California is the state’s signature vehicle-parts crime. When the National Insurance Crime Bureau published claims-based figures for the peak year of 2022, the nation recorded more than 64,000 converter thefts — and California and Texas together accounted for over 32,000 of them.
Thefts then fell sharply as metal prices collapsed. What matters now is that the thing driving the original wave has reversed direction again.
Why this crime follows a commodity market
A catalytic converter contains small quantities of platinum, palladium, and rhodium. When those prices climb, the scrap value of a stolen converter climbs with them and the crime becomes worth the risk. When prices fall, it fades — which is exactly what happened between 2022 and 2024, as rhodium fell from extraordinary highs and theft volumes dropped with it.
Platinum-group metal prices rose substantially through 2025. That’s the mechanism behind every previous wave, and it’s the reason converter theft doesn’t follow the same curve as burglary or vehicle theft: it responds to a commodity market rather than to policing.
What the data can and can’t tell you right now
This is worth stating plainly, because a great deal of published content on this topic quietly ignores it.
The verifiable national record on converter theft comes from insurance claims data, and that trail effectively stops in mid-2024. No national figure for 2025 or 2026 has been published in a form that can be independently checked. Individual cities have reported sharp increases, and the price driver has clearly reversed — but anyone quoting a confident national total for right now is extrapolating rather than citing.
There’s a second limitation underneath that one: claims data only counts vehicles whose owners carried coverage that would produce a claim, and roughly half of US vehicles don’t. Claim counts are a floor, not a census.
So the honest position is: the conditions that produced the last wave are back in place, several cities report renewed activity, and no reliable national number for the current period exists. That’s less satisfying than a headline figure, but it’s what the evidence supports.
Why commercial property is the natural target
The economics favour volume, and volume means fleets.
A single converter takes only minutes to remove with a battery-powered saw. It requires no keys, no immobiliser defeat, and no way to drive the vehicle off the property — the vehicle stays exactly where it was. That’s why a row of identical fleet vans is worth far more to a thief than a single car on a residential street: the same job, repeated down the row, on ground nobody is watching.
The property types carrying the most exposure:
- Fleet and service yards — identical vehicles in rows, unattended from close of business until morning
- Dealership lots — high vehicle density, open ground, inventory that must stay saleable
- Office and multi-tenant parking structures — poorly lit levels with no natural surveillance after hours
- Municipal, school, and shuttle fleets — vehicles parked in the same place, in the same configuration, every night
- Rental and car-share lots — high turnover means the damage often isn’t found until a customer finds it
The cost is not the part
The scrap value of a stolen converter is modest. The replacement is not, and neither is the collateral damage — cutting a converter out frequently damages the exhaust system and surrounding components, and the vehicle is undriveable until repaired.
For a fleet, the real cost is downtime. A service business that loses four vans in one night has lost four vehicles’ worth of jobs for as long as parts and labour take. For a dealership, a converter cut from new inventory means a unit that can’t be sold until it’s fixed.
What partly works — and what doesn’t
Etching and marking converters makes resale harder and can support a prosecution. It doesn’t stop the cut.
Cages and shields physically slow removal on specific models. Genuinely useful on high-target vehicles, but a per-vehicle cost that raises the time required rather than removing the option.
Lighting without observation gives a thief better working conditions.
Recorded cameras are the most common answer and the weakest. The cut takes minutes; by the time footage is reviewed the next morning the vehicles are already down, and overnight footage of someone under a van rarely produces an identification.
Fencing and gates matter, but fleet yards need vehicle access and parking structures are open by design.
What actually interrupts it
Because the crime is fast, the only intervention that changes the outcome happens while it’s underway — and on an unstaffed lot, that means someone watching in real time.
Live video monitoring puts an agent behind the cameras who sees a vehicle stop at the fence line, sees someone go underneath the third van in the row, and speaks to them through an on-site speaker before the cut is finished. A live human voice describing what someone is doing, right now, ends most attempts — a fundamentally different signal from a siren, because it tells the intruder a person is watching.
That live account matters for a second reason in California. A growing number of cities now require verified response — independent confirmation that a crime is actually in progress — before police will dispatch to an alarm. A monitored feed produces that confirmation; a recording nobody is watching does not.
For open ground that fixed cameras don’t cover well — back rows, overflow parking, yards that change configuration — solar-powered surveillance trailers deploy in hours without permanent power or network, and can be repositioned as the site changes.
A practical checklist
- Identify your highest-target vehicles. Hybrids are targeted for converter composition; trucks and vans because there’s room to work underneath.
- Park defensively. High-target vehicles in the interior of the lot, backed against walls or each other, low-target vehicles on the perimeter.
- Walk your lot at night. Find the spots where someone could work unseen by every camera. Most yards have more than management expects.
- Cover the overflow. Secondary lots are routinely excluded from the security plan and are the softest ground you own.
- Check your alarm status. Verification requirements and false alarm penalties vary by city — know where you stand before you need a response.
- Document what you’ve done. Insurers increasingly ask what measures were in place, and a repeat claim with no changes between incidents is a difficult conversation.

Guardian Integrated Security covers fleet yards, dealership lots, and parking structures across California. Monitoring agents watch your existing cameras live, challenge intruders over on-site speakers, dispatch Guardian’s own patrol, and alert and coordinate with local police with a verified account of a crime in progress.

Sources
Peak-year theft figures come from the National Insurance Crime Bureau‘s claims-based reporting for 2022, which recorded more than 64,000 converter thefts nationally with California and Texas together accounting for over 32,000. Subsequent decline and the limits of the current data record reflect published insurer claims analysis, which ends in mid-2024. Platinum-group metal price movements are drawn from commodity market reporting.
