Schemes that trick people into handing over money or access, from phone impostors to investment frauds such as Ponzi and affinity schemes.
See it on the Personal Finance & Estate map →How it works
Scams share a playbook: urgency, secrecy, a trusted-seeming source and an unusual way to pay, such as wires, gift cards, crypto or cash handed to a courier. A Ponzi scheme pays early investors with new investors' money until inflows stop. Affinity fraud spreads through a church, ethnic or professional community, where shared trust replaces due diligence. Americans reported $12.5 billion in fraud losses to the FTC in 2024, and $16.6 billion in internet-crime losses to the FBI.
Why it matters for you
Stolen money is rarely recovered, so the main defense is habit: pause, verify through a number you look up yourself, and never let anyone rush a payment.
Think of it like
A Ponzi scheme is like a sponsor paying promised distributions out of the next investors' capital instead of from rents.
Red flags and protection
FTC Consumer Sentinel and FBI Internet Crime Complaint Center (IC3) annual reports; Charles Ponzi's 1920 Boston scheme; Bernard Madoff's 2008 collapse, about $65 billion in paper losses, of which a court trustee has recovered over $14 billion.
Watch out for
Reported figures capture only part of the losses, since many victims, especially older adults, never report out of embarrassment or not knowing where to go.
Inside this (5)
Connections (6)
▸Impostor scams (IRS, SSA, Medicare, 'grandchild in trouble') are a top form of Financial scams & fraud (incl. affinity & Ponzi schemes)Watch out
How they connect
Impostor scams are the most-reported type of fraud. They use the general scam playbook in its purest form: borrow the authority of an agency, a bank or a relative, create panic, and demand payment by a method that is hard to trace or reverse, such as gift cards, wires or crypto.
When it applies
Nationwide, by phone, text and email; government impersonation surged around 2013 with overseas call centers posing as the IRS, and later as Social Security.
How sure?
FTC Consumer Sentinel data have ranked impostors the top fraud category by reports in recent years, tracking government, business and family-and-friend impostors as subtypes.
Watch out for
Reported figures understate losses, and how much AI voice and video cloning will add has not yet been measured.
▸Medicare fraud & medical identity theft (report to SMP) is a costly form of Financial scams & fraud (incl. affinity & Ponzi schemes)Watch out
How they connect
Medicare fraud is financial fraud aimed at a government payer rather than a bank account. Scammers use the same lures as other scams, such as free items, urgent calls and fake officials, to collect Medicare numbers, then bill for services that never happened, at a scale of billions.
When it applies
Run by sham equipment suppliers, labs, clinics and telemarketers, often across states and overseas; Justice Department health-care fraud strike forces have targeted them since 2007.
How sure?
HHS inspector general reports and yearly Justice Department takedowns document the schemes, defendants and losses; the 2025 takedown alleged about $14.6 billion.
Watch out for
Total fraud is unknown because much is never detected, and official 'improper payment' figures mix fraud with simple billing errors.
▸Identity theft & the IRS IP PIN feeds Financial scams & fraud (incl. affinity & Ponzi schemes)Watch out
How they connect
Stolen identities are raw material for many scams. Data from breaches, phishing or a lost wallet let criminals open credit, take over accounts and file fake tax returns, and make impostor calls more convincing because the caller already knows an address or the last four digits of a Social Security number.
When it applies
Ongoing; giant breaches such as Equifax's in 2017, which exposed data on about 147 million Americans, keep feeding fraud for years afterward.
How sure?
FTC reports track identity theft alongside fraud; prosecutions often show breach data sold on criminal marketplaces and reused in scams.
Watch out for
Linking a specific fraud to a specific breach is usually impossible, so the full downstream cost of breaches is unknown.
▸Real-estate wire fraud & deed (title) theft is a property-owner form of Financial scams & fraud (incl. affinity & Ponzi schemes)Watch out
How they connect
Real-estate wire and deed fraud apply the scam playbook to property: impersonate a trusted party, such as the escrow officer or the owner, and divert the largest payment in the deal. Because wires settle within hours and deeds are public records, criminals can research targets and strike quickly.
When it applies
Nationwide, through hacked email at brokerages, escrow and title firms, and through remote 'sellers' using fake IDs and notaries, which grew as closings went remote.
How sure?
FBI IC3 reports, title-industry surveys and county fraud cases document the schemes; prosecutions show stolen funds moved through money-mule accounts.
Watch out for
Total losses are unclear, because title companies stop many attempts before closing and others are counted as business email compromise.
▸Romance & crypto 'pig-butchering' scams are a fast-growing form of Financial scams & fraud (incl. affinity & Ponzi schemes)Watch out
How they connect
Pig-butchering, named for a Chinese phrase about fattening a pig before slaughter, blends two old cons, the romance scam and the fake investment, with crypto as the payment rail. Because transfers are fast, global and hard to reverse, losses per victim run far higher than for most consumer frauds and can reach six or seven figures.
When it applies
Emerged in China around 2016–2019, then moved to compounds in Cambodia, Myanmar and Laos during COVID, targeting victims worldwide, including many Americans.
How sure?
FBI IC3 data show investment fraud, mostly crypto, as the largest loss category in 2023 and 2024; UN and US Treasury reports trace the compounds.
Watch out for
How much of the money flows to large organized-crime groups versus smaller crews, and whether 2025 crackdowns slowed them, is unclear.
▸Financial & consumer regulators police Financial scams & fraud (incl. affinity & Ponzi schemes)Law or rule (2026)
How they connect
Regulators split the territory: the SEC and state securities regulators pursue investment frauds and Ponzi schemes, FINRA polices brokers, the FTC and CFPB handle consumer scams, and the FBI and prosecutors bring criminal cases. In California, the Department of Financial Protection and Innovation (DFPI) licenses advisers, lenders and crypto firms.
When it applies
Federal agencies in Washington with regional offices; California's DFPI took its name and broader consumer powers in 2020. Reports go to sec.gov, reportfraud.ftc.gov and ic3.gov.
The rule
Each agency publishes enforcement actions and annual reports; the SEC alone brings dozens of offering-fraud and Ponzi cases a year.
Watch out for
Overlapping jurisdiction leaves gaps, especially for crypto, where federal policy shifted in 2025 and California's crypto licensing law took effect only in July 2026.
