Dollar range in a data-dependent rate regime

Start with the regime overlay

After the US hiking cycle paused and policy was framed as data-dependent, near-term dollar yield support was expected to thin. Still-higher US nominal rates limited aggressive selling. That leftover cushion is yield protection: the residual support a currency keeps while its nominal rates still sit above peer rates, even after a hiking cycle pauses.

Editorial interpretation: treat the single dollar-pair idea as a regime overlay first. Map relative policy paths, leftover yield protection, and reserve-flow pressure. Only then convert the leftover weekly price box into a falsifiable range procedure.

Intermarket bias from policy paths and the external gap

The archive weaker-dollar lean was an intermarket bias. It came from US growth moderation and a large current-account gap versus likely further ECB and Bank of Japan tightening. Later-2006 Eurozone doubts could still cap euro gains. The lean was not taken from one pair’s last candle.

Mixed US prints were read as moderation that could reopen early-next-year cut risk: third-quarter growth at a 1.6 percent annual rate, July payrolls of 113,000, unemployment at 4.8 percent, and an 11.9 percent drop in new-home sales in the year through June 2006. Core consumer prices rose 0.3 percent in June and the core annual rate reached 2.6 percent, so the August policy statement left any further tightening data-dependent. The more likely path was no extra hike, with 10-year yields near 4.80 percent.

Structural dollar vulnerability was tied to a current-account deficit above 6 percent of GDP, a monthly trade gap still above 60 billion dollars, and mixed reports of official reserve rebalancing with less official bond buying. Peer policy paths were already tightening. The ECB raised rates by 0.25 percent to 3.0 percent in early August, with inflation at 2.4 percent versus a 2.0 percent target and M3 at 8.5 percent. The Bank of Japan lifted rates from zero to 0.25 percent in July.

Editorial interpretation: policy-lag risk is the delay between rate moves already delivered and their later hit to growth. That delay can reopen cut or hike odds inside the same range, so the overlay stays two-sided.

The leftover weekly box

After the April decline, euro-dollar found support near 1.30, recovered just beyond 1.25 in late June, then slipped back toward 1.29 from mid-July as pause speculation built. The archive weekly operating hypothesis boxed the US Dollar Index between 8400 and 8700 and euro-dollar between 1.25 and 1.30.

That band is the support-and-resistance box: a repeatable high-low band used to state where a range hypothesis is confirmed or broken. Institutional buying on euro pullbacks was treated as a barrier to large dollar gains.

Turn the box into a range procedure

The weekly operating hypothesis was a range procedure. Sell defined resistance and buy defined support. Stay out when price leaves the box.

Editorial interpretation: the leftover weekly highs and lows are the test, not a prompt to recast the same band as a breakout. Relative policy paths, leftover yield protection, and reserve rebalancing explain why the box exists. They do not replace the rule that a close outside 8400 to 8700 on the Dollar Index, or outside 1.25 to 1.30 in euro-dollar, ends the range procedure.
