In February 2016, hackers tried to steal roughly $1 billion from the central bank of Bangladesh without ever entering a building. Malware suspected to be a Dridex variant had been sitting inside Bangladesh Bank's systems since January, watching employees and learning the exact syntax of the SWIFT messaging network. Then, on the night of February 4th into the 5th, as the Bangladeshi weekend began, the attackers sent 35 fraudulent transfer instructions to the Federal Reserve Bank of New York.

This episode follows the money and the mistakes. The Fed flagged 30 of the requests, worth about $850 million, and a misspelling of the word foundation in a $20 million transfer to Sri Lanka drew the attention of Deutsche Bank. But $81 million still reached four dormant accounts at an RCBC branch in the Philippines, where a Chinese New Year bank holiday and a casino loophole in anti-money laundering law let it disappear. The trail leads to the Lazarus Group and North Korea's Reconnaissance General Bureau.

• The attackers timed the transfers for Thursday night in Bangladesh, when the bank's weekend had begun but the New York Fed was open and processing transactions.
• A $20 million transfer to the Shalika Foundation in Sri Lanka was stopped after Deutsche Bank noticed the word foundation was misspelled.
• The four RCBC accounts on Jupiter Street in Makati City were opened under fictitious identities in May 2015, nine months before the heist.
• Philippine casinos were excluded from anti-money laundering reporting rules, so the funds were converted to pesos and washed through casino chips and junket operators.
• Of the $81 million that reached the Philippines, only about $15 million has been recovered. RCBC paid a record fine of roughly $52.9 million, and SWIFT created its customer security program in response.

Double your bet after every loss, and the first win recovers everything plus a profit equal to your original stake. The Martingale system, which dates to 18th century France, sounds like a law of physics, and it found a natural home at the roulette table, where red or black comes close to a coin flip. This episode shows why it is a trap. The guarantee holds only for a player with unbounded wealth, unbounded time, and a casino that accepts unbounded bets. Take away any one of those and the structure collapses, which makes it a dark mirror of the St. Petersburg paradox.

The math is worked through with a 63-unit bankroll on an American double-zero wheel, where a red or black bet loses 20 times out of 38. Bets of 1, 2, 4, 8, 16, and 32 exhaust the bankroll in six spins. From there the discussion turns to why people keep trusting the system: we expect randomness to look evenly mixed when it is clumpy, and we mistake a rare streak on one attempt for a rare streak across a long session.

• With 63 units the player wins one unit 97.87 percent of the time, yet the 2.12 percent wipeout is heavy enough to make the expected value about negative 0.36.
• On a single-zero wheel, a six-loss streak is a 1.8 percent event in isolation, but across 200 plays the chance of meeting one rises to 84 percent.
• Keeping the risk of ruin under 10 percent over 5,000 plays means surviving 15 straight losses, which takes more than 65,500 times the original bet.
• Joseph Doob's optional stopping theorem shows that with limits on bankroll or bet size, no choice of when to quit turns a negative-expectation game profitable.
• The reverse Martingale, which doubles after wins, fails too: the first loss takes the largest bet of the run and erases every unit of profit.

Every evening the news reports what the Dow did, as if it were a precise reading of the American economy. The number comes from a newspaperman's pencil arithmetic. Charles Dow, a reporter, and statistician Edward Jones founded Dow Jones and Company in 1882 and ran a two-page bulletin, the Customer's Afternoon Letter, around a Wall Street that was opaque to outsiders. That letter grew into the Wall Street Journal. On May 26, 1896, Dow added up the share prices of 12 industrial stocks, divided by 12, and published the first Dow Jones Industrial Average: 40.94.

That simple method made the Dow a price-weighted index, where a company's share price matters and its actual size does not. This episode explains the Dow divisor invented to patch over stock splits, why 30 companies make a narrow sample, and why advisors steer clients toward the S&P 500. It also explains why the index still tracks the wider market, and how a committee that swaps fading firms for rising ones keeps the long-run line climbing.

• Dow's first average, in 1884, tracked 11 stocks, nine of them railroads. It later became the Dow Jones Transportation Average.
• The divisor is now about 0.168, so a one dollar move in a single component shifts the Dow by roughly 5.94 points.
• In 2008 AIG carried one of the highest share prices in the index, and its collapse dragged the average down out of proportion to the rest.
• Goldman Sachs currently holds the heaviest weighting purely because its share price is the highest, not because it is the largest company.
• The Dow closed near 59 in the depths of 1932, crossed 10,000 in 1999, broke 30,000 in 2020, and passed 48,000 in 2025.

On Christmas Day 1864 in the American South, a turkey cost $155, a ham $300, a cake of soap $50, and an ordinary suit of clothes $2,700. The money behind those prices was the Confederate States dollar, the grayback, first issued in April 1861 when the Confederacy was two months old. It was a bill of credit with no gold or silver behind it. Most notes promised payment six months after the ratification of a treaty of peace between the Confederate States and the United States, which made every bill a wager on victory.

This episode examines the economics and logistics of that wager without endorsing the Confederacy or the institution of slavery it fought to preserve. It tracks how battlefield news moved the currency, how roughly $1.7 billion in unbacked paper fed runaway inflation, and how a government cut off from engravers, paper mills, and presses resorted to lithography and hand-signed notes that invited forgery. When the Confederacy ceased to exist, the money went to zero at once.

• News of the defeat at Gettysburg cut the currency's value by 20 percent. By September 1864 one paper dollar was worth three cents in gold.
• In October 1863 Senator Louis Wigfall of Texas noted that a soldier's $11 monthly pay bought what a single dollar had at the start of the war.
• Jefferson Davis asked citizens to agree among themselves to buy and sell at reduced prices while the government kept printing.
• Up to 200 clerks, often women, hand-signed notes for the Register and Treasurer, so a forger only needed a scribble that looked official.
• Philadelphia engraver Robert Lovett Jr. struck sample Confederate cents in 1861, feared a treason charge, and hid the coins and dies in a cellar. Fourteen are known today.

On August 18, 1913, a roulette wheel at the Monte Carlo Casino landed on black 26 consecutive times, odds of roughly one in 68.4 million. The crowd that gathered was sure red was due and pushed millions of francs onto it as the streak ran on. They lost fortunes to a belief that random events keep a ledger. This episode takes that night as the entry point to the gambler's fallacy, using a simple coin toss to show the error: five heads in a row is a 1 in 32 shot before you start, but after four heads the fifth flip is still 50-50, because the coin has no memory.

The instinct is old. In 1796 Pierre-Simon Laplace described expectant fathers who feared that a run of boys born nearby had used up the supply. Amos Tversky and Daniel Kahneman traced it to a belief in the law of small numbers, and brain imaging shows what happens after a loss. The episode then follows the bias into asylum courts, ballparks, banks, lotteries, and video games, and asks whether it can be unlearned.

• U.S. asylum judges were 5.5 percent less likely to approve a request after granting the previous two, and loan officers were 8 percent less likely to approve after a prior approval.
• Major League Baseball umpires were 1.3 percent less likely to call a strike when the previous two pitches had been called strikes.
• When the number 244 won a lottery in April 1988, 41 players had picked it. Three days later only 24 did, and it took two months for bets to recover.
• A 1967 experiment found that people explicitly taught about the fallacy performed identically to those who were not.
• The fix that worked was reframing: when participants treated a toss as the first of a new block instead of the last of an old one, the fallacy disappeared.

In 1899, as railroad tycoons and steel magnates crowded into rooms once reserved for old money, Thorstein Veblen published The Theory of the Leisure Class and gave the spectacle a name: conspicuous consumption. The new rich had no lineage to display, so they displayed waste, in money and in time. Like a peacock's tail, the cost and impracticality were the whole message. This episode starts there and follows the habit downhill, through Paul Nystrom's pecuniary emulation in the 1920s and James Duesenberry's 1949 bandwagon and demonstration effects, to a middle class pegging its spending to the neighbors.

The modern evidence is everywhere: McMansions that swallow yards and retirement funds, off-road SUVs idling in suburban traffic, loud logos giving way to quiet luxury. The conversation then turns to the cost, including debt taken on to imitate the wealthy and savings drained into status goods, and to the remedies economists have proposed, from luxury taxes to a progressive consumption tax.

• The 1996 book The Millionaire Next Door by Thomas J. Stanley and William D. Danko found many real millionaires practice conspicuous frugality, such as paying cash for a five-year-old used car.
• A 2013 survey of more than a thousand Americans found men scored higher on overt materialism, women on impulse purchases, and both were equally prone to brand loyalty.
• Robert H. Frank's expenditure cascade describes spending norms set at the top rolling down every rung of the income ladder, often paid for with credit.
• Dick Meyer's 2006 idea of aggressive ostentation reads the loudest purchases as an angry demand to be noticed in an anonymous society.
• John Stuart Mill argued that goods bought purely for their costliness are ideal to tax, since a higher price does not spoil them for the buyer.

Textbooks tend to describe wampum as a kind of early money. For the peoples of the northeastern woodlands who made it, that misses nearly everything. White beads came from the inner spiral of the channeled whelk and dark purple ones from the quahog clam, each drilled by women artisans using a wooden pump drill tipped with quartz, then strung and ground smooth with sand and water. As anthropologist David Graeber put it, wampum was used to rearrange relations between people. Belts recorded treaties, strings served as a chief's or clan mother's certificate of office, and a name string laid on a successor's shoulder passed on a dead leader's title and obligations.

Europeans saw something scarce and prized and made it currency. This episode follows that hijacking, from legal tender in New England between 1637 and 1661 to counterfeit dyed beads, a fur trade bought with hoarded shells, and factory output that inflated it into worthlessness. It ends with the belts coming home and with Native artists making wampum again on their own terms.

• The Two Row Wampum shows two purple lines on a white field: a Native canoe and a European ship traveling side by side, neither steering the other.
• The Dutch set eight white or four purple beads to one copper coin, and counterfeiters soon dyed white beads dark to double their value.
• John Campbell opened a wampum factory in New Jersey in 1746. At its peak, from about 1835 to 1866, the family turned out a million black beads a year.
• In 1989 the National Museum of the American Indian returned 11 wampum belts to Haudenosaunee chiefs at the Onondaga Longhouse after more than a century away.
• The Unkechaug Nation built its own wampum factory on Long Island in 1998 to supply Native artists such as Ken Maracle and Elizabeth James-Perry.

In 2013 Costco CEO Craig Jelinek suggested to co-founder James Sinegal that the quarter-pound hot dog and soda combo, stuck at $1.50 since 1985, might need a price increase. Sinegal cursed him out for even thinking it. The combo loses money every year, as does the $4.99 rotisserie chicken, and that is the design. A loss leader is priced below cost so that the rest of your cart pays for it, and retailers use basket data from millions of receipts to know exactly what else you will buy once you are through the door.

This episode walks through the mechanics: why milk and bananas sit in the far corner of the store, why purchase limits and perishability stop anyone from raiding the bargain, and how the same play scales from British Christmas vegetables to motorcycles in pawn shop windows. It also covers the hardware version of the trap, where printers, game consoles, and power drills are sold cheap so that ink, games, and proprietary batteries can earn the money back.

• In the UK Christmas price war, Tesco, Asda, Sainsbury's, and Morrisons have cut seasonal vegetables to 8 pence per kilogram, against a usual price near 70 pence, to win the holiday shop from Aldi and Lidl.
• In 1959 the British Motor Corporation priced the basic Mini at 496 pounds, losing roughly 30 pounds a car, and expected buyers to trade up to the 537 pound Deluxe. They bought the stripped model in droves.
• American car dealers stay inside bait-and-switch law by tying an advertised low price to one vehicle identified by its VIN, which sells almost at once.
• Printer makers embed chips in ink cartridges so the firmware rejects cheap third-party refills, locking buyers into the product that carries the profit.
• In the 1970s Warner and Reprise sold double-LP samplers openly named Loss Leaders for two dollars by mail, hoping listeners would then buy full-price albums.

The phone battery that fades the week a new model arrives and the printer that refuses to scan without cyan ink belong to a philosophy with a century of history. It began in the 1920s car market. Henry Ford built the Model T from durable vanadium steel and wanted it to last forever, which left a saturated market with nobody needing a replacement. Alfred P. Sloan Jr. of General Motors answered with dynamic obsolescence: the 1923 Chevrolet put a restyled body on technology nearly a decade old, and the annual model change turned a tool into a fashion statement.

This episode follows the idea from Depression-era proposals to legislate expiration dates through the engineering tricks of today: brittle gears, glued-in lithium-ion batteries, proprietary screws, parts that check each other's serial numbers, and ink chips that count pages. It also weighs the argument that fast replacement cycles drive innovation against the waste they produce, and surveys the laws now pushing back in France, Quebec, the European Union, and American states.

• In 1932 real estate broker Bernard London proposed legal expiration dates on shoes, tractors, and building materials to force demand and end the Depression.
• Industrial designer Brooks Stevens popularized the term in 1954, defining it as the desire to own something a little newer, a little better, a little sooner than is necessary.
• Many front-loading washers now mold the drum bearing into the plastic drum, so one worn metal ring can cost more to fix than the machine is worth.
• Hewlett-Packard settled a class action over cartridge chips with $5 million in credits, and Canon was sued over all-in-one printers that disabled scanning when ink ran out.
• France made planned obsolescence illegal in 2015, with fines up to 300,000 euros and up to two years in jail. The EU will require user-replaceable batteries by 2026.

The traditional piggy bank asks a child to protect and feed a ceramic animal for months and then destroy it with a hammer. That paradox is the point. Collectors call it a still bank, a vessel with no moving parts where money goes in through a slot without effort and comes out only by sacrifice. This episode treats it as an ancient commitment device, the same trick as freezing a credit card in a block of ice, built to override a brain that evolved to consume resources on the spot.

The story begins long before the pig. The oldest known Western money box, from the Greek colony of Priene in the second century BC, is a miniature terracotta temple with a coin slit in the pediment. From there the trail runs through Pompeii and Herculaneum, Song dynasty China, medieval Bruges, and Tudor England, then turns to Java and Germany, where two cultures separately decided that savings should look like a pig.

• Temples were the vaults of ancient cities, so a temple-shaped box borrowed divine security. Breaking it open meant a small act of sacrilege.
• A large cache of boar-shaped banks was found at Trowulan in East Java, believed to be the capital of the Majapahit Empire, where copper cash coins needed a home.
• In Javanese, celengan means likeness of a wild boar. The same word still means both the clay bank and the act of saving in modern Indonesian.
• The earliest known German piggy bank dates to the 13th century and was found in Thuringia, where a pig fed on scraps was a peasant family's living savings account.
• The popular tale about orange pygg clay has no evidence behind it. The Oxford English Dictionary first records pig bank in 1902 and piggy bank in 1913.
