Why stablecoin routing now matters more than FX spreads

Stablecoin cross-border payments priced below interbank foreign exchange rates in every month of the second quarter, according to Borderless.xyzs Q2 2026 benchmark.

The report tracked 260 payment corridors across 108 countries and 59 currencies, using 2.96 million rate observations.

The median Parity Gap stood at minus 3.2 basis points for the quarter. One basis point equals 0.01%. The measure compares the delivered stablecoin price with the interbank midpoint. It moved from minus 2 basis points in April to minus 5.9 basis points in June, its lowest reading this year.

Stablecoin FX moves below interbank pricing

A negative Parity Gap means stablecoin delivery reached customers below the rate banks use when trading with each other. Borderless said that result remained rare across cross-border payment systems. Some provider rates include fees inside the exchange rate, so the measure reflects all-in pricing rather than pure FX execution.

The median cost of delivering a $10,000 payment stayed near $27 through Q2. It has remained within 30 cents of that level for five months. The median provider spread also held at 98.8 basis points from March through June after most compression occurred during Q1.

Routing becomes the largest remaining cost lever

Borderless found that provider choice now creates the widest avoidable cost. A business using the median provider instead of the best available route paid 23.3 basis points more. That equals $2,330 for every $1 million moved across 81 corridors.

The cheapest provider changed frequently. On the USDT-to-Brazilian-real corridor, the lead changed 34 times during 88 days, or about every 2.6 days. No provider held first place for half the quarter. The report called this difference the “Routing Tax.”

The network included 377 payout routes across seven blockchains. Borderless counted 82 corridors with at least two steady providers, including 18 with three or more. Those backup routes kept payments moving when a leading quote became less competitive.

Asset and corridor choices change final prices

USDC and USDT differed by only 0.4 basis points across the network, but individual corridors produced much larger gaps. USDC traded at a persistent 99-basis-point discount to USDT in Peru. Chile and Switzerland showed smaller pricing advantages for USDT.

Large payment flows also increased the cost of weak routing. Mexicos 21.5-basis-point USDT routing gap applied to $67.6 billion in annual remittance inflows. Borderless estimated the same annual leakage as Colombia, where a 122.8-basis-point gap applied to much lower volume.

Regional pricing remains uneven

Africas median provider spread widened by 166 basis points to 512.8 during Q2. Malawi recorded the largest repricing. Its typical spread moved from about 296 basis points to 1,975 after a 5.8% change on April 9, with no backup provider available.

Ghana also faced wider pricing, but several providers remained active. The best quote stayed 258 basis points below the median on a day. Borderless cautioned, “None of these numbers is your number,” because each business pays according to its corridors, providers and ticket sizes.

As previously reported, stablecoin payment use has moved beyond crypto trading into business payments, payroll and cross-border settlement. Real-world stablecoin payments doubled to about $400 billion in 2025, with business-to-business transfers making up activity.

Payment companies are also widening stablecoin coverage. dLocal launched stablecoin services across more than 44 markets, while SBI Remit partnered with Fasset on infrastructure spanning over 50 payment corridors. Borderless said businesses can now save more through dynamic routing than by relying on one fixed provider under competitive market conditions.
