Changing money in Chiang Mai

The site tracks two counters in Chiang Mai, both belonging to Super Money Chiangmai: one on Loi Kroh Road by the Night Bazaar, and one on Sri Phum Road (Ratchawithi) at the north moat of the Old City. Chiang Mai airport is tracked on its own page.

Both branches keep the same hours, 08:30 to 17:30, and both open on Sunday. They quote 14 currencies, a shorter board than the big Bangkok chains carry, so if you have something unusual check the live table before walking over. On 28 September 2026 the best US dollar buying rate was 33.50 baht against a mid-market rate of 33.42, and both branches posted the same figure, so the spread across the two was zero; choose by which side of town you are on rather than by rate. The Japanese yen best was 0.2115.

For the wider picture, the guide to Chiang Mai money exchange covers the Old City, Night Bazaar and Nimman, and there is a separate Super Money Chiangmai guide on the two branches, their hours and rates. Arriving by air, the airport-to-Old-City guide prices the ride in.
