Geographic Arbitrage

Mar 7, 2026

Earn in dollars or euros, spend in baht or pesos. Geographic arbitrage is the primary driver for a growing number of people relocating abroad.

The numbers

According to public 2026 cost-of-living indices, four popular destinations compared to New York City (rent included):

Lisbon: 53% lower
Mexico City: 61% lower
Bangkok: 68% lower
Medellin: 74% lower

A one-bedroom in Medellin runs about 85% less than the same in Manhattan. Groceries in Bangkok are roughly half the cost.

Portugal

Portugal's D7 visa is designed for passive income holders: pensions, dividends, rental income. The minimum is EUR 920/month, pegged to the Portuguese minimum wage, one of the lowest income thresholds in Europe.

For remote workers, Portugal's separate D8 visa requires 4x the minimum wage, or EUR 3,680/month. The two were split in 2024.

Portugal's NHR tax regime ended January 1, 2025. Its replacement, IFICI, offers a 20% rate on domestic employment and self-employment income but is restricted to qualified professionals in science, technology, healthcare, and green energy. Retirees are no longer covered.

Mexico

Mexico's temporary resident visa requires proof of 680 UMA days/month in income, or 11,460 UMA days in savings over the past 12 months. With the 2026 UMA at MXN 117.31/day, that's MXN 79,771/month (USD 4,400) in income or MXN 1,344,373 (USD 74,700) in savings.

That income threshold has more than doubled since 2022. Mexico switched from minimum wage to UMA (a separate economic index) for calculating residency requirements in July 2025, which slows future annual increases to 3-5% instead of 12-13%. But the current bar is already high.

Requirements vary by consulate. Some ask for 6 months of bank statements, others want 12.

Thailand

The retirement visa (O-A) requires 800,000 THB (USD 23,800) in a Thai bank account, or monthly income of 65,000 THB (USD 1,900). You must be 50+.

For younger earners, the LTR visa through Thailand's Board of Investment offers a 10-year stay. The "Work-from-Thailand Professionals" category requires USD 80,000/year in income (or USD 40,000-80,000 with a master's degree). It comes with a flat 17% income tax rate.

Colombia

The cheapest entry point. Colombia's digital nomad visa requires 3x the minimum wage (COP 1,750,905 for 2026), which works out to COP 5,252,715/month (~USD 1,400). The visa lasts up to 2 years.

The minimum wage jumped 23% from 2025 to 2026, automatically pushing the threshold up. Reports from mid-2025 suggest the Ministry of Foreign Relations has started restricting the visa to IT workers and online content creators, though no official decree has been published. Confirm with the consulate before applying.

The calculation

If you're earning USD 6,000/month remotely or drawing an equivalent retirement income:

In Lisbon, that buys a lifestyle equivalent to roughly $12,900/month in New York
In Bangkok, closer to $18,600/month in purchasing power
In Medellin, about $22,800/month equivalent

These are rough conversions using public cost-of-living ratios. YMMV.

tl;dr

Portugal has the lowest income threshold in Europe (EUR 920/month for passive income) but lost its tax advantage for retirees. Mexico's threshold has spiked to ~$4,400/month. Thailand's retirement visa is accessible at $1,900/month but age-restricted. Colombia is the cheapest at ~$1,400/month but may be narrowing eligibility.
