Transaction Costs
A price gap becomes an opportunity only if it survives every cost required to capture it. Shipping, conversion, financing, settlement, regulation, and selling friction can consume the entire spread.
Coupons bought cheaply in Italy and resold in the United States sound like easy arbitrage—until the host adds one mundane phrase: plus shipping. That single expense may turn the apparent profit into no opportunity at all.
E1The gap is not the gain
A quoted price difference compares two endpoints; profit depends on the costly path between them. You must buy the asset, move or convert it, finance the interval, satisfy each market’s rules, complete settlement, and find a buyer. Each step subtracts from the spread, while delays and operational failures add exposure. Arbitrage exists only in the remainder.
This friction also explains why the law-of-one-price is a tendency rather than an instant command. Traders close gaps only when the expected proceeds exceed the full cost of connecting the markets. economies-of-scale can change that calculation: a route that loses money for one coupon may work at sufficient volume because fixed logistical costs are spread across many units.
E1Persistent gaps may be telling the truth
Transaction costs do not prove that every price difference is illusory. They show why a surviving gap may reflect costly separation rather than free money—and why viability can differ by trader, volume, financing, and available alternatives. That last comparison is a context-dependent-opportunity-cost, not a universal verdict.
E1Price the entire route
Before calling a spread an opportunity, write a landed-profit equation: expected sale proceeds minus purchase price, shipping, conversion, financing, regulatory, settlement, and selling costs. Add the time required and the minimum viable volume; act only if the conservative remainder is still positive.

The host pauses on whether Italy-to-US coupon arbitrage still works after "the cost of buying in Italy plus shipping."
