A simple theory, worth analysing:

USDJPY on 09.02.2026: $157.700 | XAUUSD: $4671
USDJPY on 09.03.2026: $158.600 | XAUUSD ?

First calculate the percentage change in USDJPY, then apply the inverse USD–Gold relationship approximation.

Step 1 — USDJPY Change

Change = +1.100

Percentage change:

158.6−157.5157.5×100\frac{158.6 – 157.5}{157.5} \times 100157.5158.6−157.5​×100

= +0.698%

Step 2 — Apply inverse USD–Gold relationship

Gold usually moves opposite to USD strength.

Gold price on 09-02-2026 = 4671

Estimated decline:

$$4671\times 0.00698\approx 32.6$$

Step 3 — Estimated Gold Price

✅ Model result

⚠️ Note:
Gold does not move only with USDJPY. The stronger drivers are:

• US 10Y real yield

• DXY

• Oil prices

• risk sentiment

USDJPY alone explains ~30–40% of short-term gold movement.

————————————————————————————————————-

Here is a simple macro correlation model traders often use for XAUUSD, combining the four main drivers:

Gold = f(DXY + US 10Y Yield + Oil + USDJPY)

Gold usually moves opposite to USD strength and yields, while oil and geopolitical risk can support gold through inflation and risk-off demand.
