BOJ in gold trading
The BOJ is Japan's central bank; its policy moves the yen and global yields, and surprises have triggered sharp swings in the dollar and in gold.
Also called Bank of Japan, BOJ decision, Yen carry trade
The BOJ (Bank of Japan) sets monetary policy for Japan. It holds eight policy meetings a year, typically announcing decisions during the Asian session without a fixed release time, followed by a press conference by the governor.
How it applies to gold trading
The BOJ influences gold through three channels. First, the yen: a hawkish surprise strengthens it and weakens the dollar, which can lift XAUUSD. Second, global yields: changes in Japanese bond policy can push up yields worldwide, a headwind for gold. Third, the yen carry trade: when investors who borrowed in yen to buy higher-yielding assets unwind, volatility rises across markets, sometimes forcing selling of gold to raise cash before haven buying returns.
Because decisions often land during Asian hours, they can produce gold moves when liquidity is thinner, and the Asian range can break before London opens.
Worked example
Example (hypothetical numbers): the BOJ unexpectedly raises its policy rate. USDJPY drops 2%, the dollar index falls 0.4% and gold jumps from 3,990 to 4,012 in the Asian session. The Asian range of 3,985 to 3,998 is broken an hour before the normal London breakout.
A common mistake
Assuming the Asian session will be quiet on a BOJ day. Check the meeting calendar.

Frequently asked questions
Does the Bank of Japan affect gold prices?
Yes, through the yen, the dollar, global yields and carry-trade flows. Surprise decisions can move gold during the Asian session.
What time does the BOJ announce its decision?
There is no fixed time; it is usually during the Asian morning on the second day of the meeting, followed by the governor’s press conference.
What is the yen carry trade?
Borrowing in yen at low interest rates to buy higher-yielding assets elsewhere. When it unwinds, investors sell those assets and buy back yen, which can cause sudden swings across markets, including gold.
