Why this index
the case for a broad dollar
DXY carries weights frozen since 1999, is majority euro, and covers no
emerging markets. The MER Dollar Index measures the dollar against the
currencies America actually trades with — developed and emerging.
Broad trade-weighted dollar measures exist, but the widely followed ones
carry illiquid currencies or sit behind a terminal. The MER Dollar Index
is computed for every US business day from market exchange rates on a
liquid basket, and it publishes the developed and emerging legs
separately — two halves of dollar strength that routinely tell
different stories. Since January 2006 the dollar has gained
39% against the emerging leg and
11% against the developed one.

The MER Dollar Index is computed by Macro Edge Research from official New York noon exchange-rate fixings — supplemented by market closing rates where official fixings do not span a series' full history — over a weighted basket of developed- and emerging-market currencies, indexed to 100 at January 2026, when Macro Edge Research began publishing it. Charts plot month-end values — the twelve-month daily panel excepted — and the tiles carry the latest daily print. A rising index is a stronger dollar; the developed and emerging legs are exact sub-indices of the same construction. The index is a coincident gauge of where the dollar is moving, not a forecast. Underlying rates publish in a weekly batch, typically Monday afternoons US time, so the newest print can sit a few business days behind today; the page refreshes daily and picks each batch up within a day. The euro-heavy comparison line is MER's reconstruction of the ICE Dollar Index (DXY) from the same fixings, shown for contrast; the currency-by-currency table is public bilateral rates and includes currencies the index does not use. ·
