⚠️ Pre-ISM USD Market — Middle East Tensions Take Priority Over Data

Nervous Conditions Ahead of Iran Deadline (Apr 8, 00:00 UTC)

■ Daily Overview

While markets are awaiting the US ISM Non-Manufacturing PMI (15:00 UTC),
the dominant driver is clearly Middle East developments, shaping overall sentiment.

The latest ISM Manufacturing data came in above expectations,
but the strength was partly driven by supplier delivery delays,
requiring cautious interpretation.

For today’s ISM Non-Manufacturing:

  • Forecast: 55.0 (still elevated)

On the surface, this could support the USD.
However, the key question is:

👉 How does a strong US economy interact with escalating war risks?


Additionally, reports indicate a two-stage peace framework
between the US, Iran, and mediating countries:

  • Phase 1: 45-day temporary ceasefire
  • Phase 2: Move toward a permanent agreement

At the same time, President Trump has warned that:

👉 If the Strait of Hormuz is not reopened,
the US may strike critical Iranian infrastructure

with a deadline of:

👉 April 8, 00:00 UTC

This highlights a situation where diplomacy and military pressure are unfolding simultaneously.


■ FX Market Developments

With European participants largely absent, liquidity remains thin,
and the USD has softened slightly:

  • USD/JPY: ~159.70 → ~159.35
  • EUR/USD: ~1.1530 → ~1.1569

This USD weakness appears to be:

👉 Position adjustment under low liquidity
rather than driven by a single fundamental factor

However, market conditions remain unstable,
and can easily reverse on:

  • Data releases
  • Middle East headlines

👉 Current phase:
Not a USD downtrend, but unstable pre-event consolidation


■ Key Event Today

US ISM Non-Manufacturing PMI (March)

🕒 15:00 UTC

  • Forecast: 55.0
  • Previous: 56.1

This release carries greater-than-usual significance.

Why it matters:

If strong:

  • “US economy remains resilient”
    → “Fed easing expectations fade”
    → USD buying

However:

👉 If interpreted alongside Middle East risks,
it could trigger:

  • Higher yields
  • Rising oil
  • Falling equities
    → Risk-off dynamics

■ Scenario Outlook

① Strong ISM

  • Reinforces US economic resilience
  • Likely initial USD buying

USD/JPY may retest 160,
EUR/USD may face resistance.

However:

👉 “Strong data + geopolitical tension”
can amplify:

  • Oil surge
  • Inflation concerns
  • Equity weakness

→ Leading to risk-off USD strength


② In-Line ISM

  • Confirms stable US economy
  • Supports USD, but lacks strong momentum

Focus likely shifts from ISM to Middle East headlines.

  • USD/JPY: volatile within 159 range
  • EUR/USD: range around mid-1.15

Markets may effectively transition toward:

👉 Waiting for the Iran deadline (Apr 8, 00:00 UTC)


③ Weak ISM

  • Triggers initial USD selling
  • Thin liquidity may amplify moves

→ EUR/USD spikes higher
→ USD/JPY drops quickly

However:

👉 USD downside may not be sustained

If geopolitical tensions escalate:

  • USD may be bought back as a safe and liquid asset

👉 “Weak data = USD down” is NOT guaranteed


■ Most Critical Perspective

This is NOT a market driven solely by ISM data.

The real focus is:

  • Strength of the US economy
  • Outcome of Hormuz Strait negotiations
  • Whether a ceasefire path emerges before
    April 8, 00:00 UTC

The proposed 45-day ceasefire offers a potential risk-off exit,
but Trump’s military threats reinforce:

👉 Risk of oil spikes
👉 Gold rally
👉 Renewed USD buying

Negotiations via mediators are ongoing,
but the probability of a deal remains uncertain.


■ Summary

Today’s market is NOT simply:

👉 “Waiting for ISM”

Instead, it is:

👉 “Passing through ISM while heading toward a geopolitical deadline”


Short-term:

  • ISM may trigger an initial move

But sustainability depends on:

  • Middle East developments

■ Key Monitoring Points

  • Strength or weakness of ISM
  • Progress in Hormuz negotiations
  • Possibility of US action against Iran

■ Final Takeaway

The current USD market is:

👉 A data-driven market on the surface
👉 But in reality, a geopolitically driven market
