EUR/USD Is Not an Order Block — It's a Central Bank Divergence Trade

The term "order block" has become forex-speak for "I don't know what just happened, so let me point at a rectangle on a chart." It doesn't matter whether the EUR/USD pair is breaking out of some drawn zone on the 4-hour or whether it's reacting to liquidity above or below any particular level. What matters is that the dollar sold off because the American jobs report came in thin — and the plumbing of two central banks just shifted beneath the pair.

Let me walk through what actually happened.

On August 7, the EUR/USD pair moved above $1.157 for the first time since mid-June, then settled around $1.156. By Friday — today — it's sitting at about 1.1563. The dollar index, DXY, which hit 101.51 on July 27th, has pulled back to roughly 99.58. That's a roughly 2% retreat from its peak in two weeks. This wasn't some chart pattern resolving. This was the US NFP report coming in significantly weaker than expected and reducing the market's probability of a September Fed rate hike.

Here's what the plumbing tells us.

The Federal Reserve held rates at 3.50% to 3.75% in its July meeting. But the vote was 9-3. Three regional governors — Hammack, Kashkari, and Logan — wanted to hike by a quarter point. Inflation has been above the Fed's 2% target for more than five years. CPI came in at 3.5% in June, but even that decline from 4.2% in May was driven by falling oil prices, not structural easing. Core inflation dropped to 2.6% from 2.9%, the first month-over-month decline since May 2020. The Fed held, buying time. The CME FedWatch tool had markets pricing a roughly 60% chance of a September hike.

Then comes the August jobs report and that number slides. The probability drops toward 54.5%, down from 63.4% the prior week. Which means the dollar weakens, because the primary reason it was strong was the expectation of Fed tightening. And when that expectation compresses, the dollar loses its mechanical bid.

Meanwhile, on the other side of the Atlantic, the ECB did the opposite. In June, the ECB unanimously raised rates by 25 basis points — the first hike in three years — pushing its deposit rate to 2.25%. Lagarde explicitly rejected the idea that this was an "insurance" move. She said inflationary pressures are real, persistent, and broadening, driven by an energy shock from the Middle East that's showing both direct costs and indirect effects on transportation and food. In July, the ECB held, but Lagarde kept the door open for another hike, potentially in September. Markets are pricing roughly a 40% chance of that second increase.

So now you have a divergence that most chart-based commentary is completely missing. The Fed is divided and may not follow through on a September hike because the jobs data softened. The ECB already moved once, has signaled it can move again, and is operating with a unified voice. The rate differential between the two central banks is narrowing — and that's the mechanical driver of the euro's strength. Not order blocks. Not chart patterns. Interest rate expectations.

There's a secondary layer too. The eurozone retail sales contracted by 0.3% in June, missing expectations. The European economy is soft. By any measure, the euro doesn't deserve this kind of strength from a growth standpoint. But currency pairs don't move on who's growing faster — they move on who's tightening faster, or who's expected to tighten faster. The ECB already tightened. The Fed is hesitating. That's what's moving the pair.

Now, understanding what I understand about how these divergence trades play out, I'd say the euro's move is fragile, and here's why. The Strait of Hormuz situation — Iran's parliament is considering proposals to restrict US and Israeli vessels and levy penalties — creates upside risk to oil prices at any moment. If oil spikes, the Fed's case for a September hike comes roaring back. Energy-driven inflation is exactly the thing that keeps the Fed hawkish, because it's not something the labor market alone can explain away. A jump in crude would reverse the entire dynamic I just described.

And there's the liquidity question, which most forex commentary ignores entirely. The Fed is still running quantitative tightening. Reserve balances have been trending down through the summer. The Treasury General Account — the US government's checking account at the Fed — absorbs reserves when tax receipts flow in and releases them when spending ramps up. If the plumbing tightens during a period of already-fragile dollar funding, the dollar can strengthen on pure mechanics, independent of rate expectations. You can have weak jobs and a hawkish ECB and still see the dollar rally if the funding markets seize up. That's what happened in September 2019, when the repo market spiked and the dollar surged despite a softening labor market. History rhymes; it doesn't repeat, but the mechanism is the same.

So here's how I'm reading the conditional chain going forward. If oil prices stay contained and Hormuz tensions ease, the euro keeps its bid and the EUR/USD pair has room to test the 1.16 area, maybe even higher. The ECB's tightening edge versus the Fed's hesitation is real, and markets will price it. If oil spikes, or if the Fed gets enough inflation data to convince the dissenters that a September hike is necessary, the dollar regains its mechanical bid and the euro retreats back toward 1.1450 or lower. If the plumbing tightens — reserves drain faster, reverse repo usage falls — the dollar can strengthen regardless of what either central bank is doing.

The mainstream narrative is calling this an "order block breakout" and pointing at rectangles on a screen. The reality is far less sexy and far more important to watch: two central banks, one divided and one unified, with an energy shock as the wildcard. That's what you trade.
