Anyone who has watched gold or EUR/USD around a CPI release or Non-Farm Payrolls report has seen it: quiet price action, then a sudden burst of movement, wide spreads and sharp reversals. Volatility spikes around major news are not random. They come from how liquidity providers, institutions and algorithms behave around scheduled uncertainty.
Why volatility rises before and around news
1. Liquidity withdraws
Market makers and liquidity providers do not want to hold inventory when a number could move price sharply. In the minutes before a release they pull or thin their quotes. With fewer orders on the book, smaller trades move price further, and spreads widen. Retail brokers pass this on, so XAU/USD spreads can be several times their normal level for a short window.
2. Positioning and pre-event hedging
Traders who are already positioned may reduce risk or hedge ahead of the event, and others place bets on the outcome. That flow can push price around in the hours before the release, even without new information.
3. The surprise versus expectations
Markets price in the consensus forecast. What moves price is the difference between the actual number and that expectation. A CPI print 0.2 percentage points above forecast can move gold and the dollar more than a large but expected change.
4. Algorithmic reaction
Many institutions trade the headline number within milliseconds using automated systems. The first move is often extremely fast, and it is frequently followed by a partial or full reversal as humans read the details (revisions, core vs headline, the press conference tone).
5. Stop clusters
Before big events, stops tend to cluster just beyond obvious recent highs and lows. A fast move triggers them, and those stops become market orders that extend the spike.
The events that move gold and the dollar most
| Event | Usual timing (New York time) | Why it matters |
|---|---|---|
| US CPI | 8:30 AM, monthly | Inflation drives Fed expectations, yields and the dollar |
| Non-Farm Payrolls | 8:30 AM, usually first Friday of the month | Labour market strength, rate expectations |
| FOMC decision | 2:00 PM statement, 2:30 PM press conference, eight times a year | Rates and guidance; the press conference often causes a second move |
| PCE inflation | 8:30 AM, monthly | The Fed’s preferred inflation measure |
| US GDP, retail sales, ISM PMIs | Varies | Growth expectations |
Use an economic calendar (MT5 has one built in) and check the impact rating and consensus forecast before the session.
How traders handle news volatility
- Stand aside: close or avoid new positions a few minutes before and after high-impact releases. Simple and often the best choice for strategies not designed for news.
- Reduce size: if you must hold, cut size so a gap through your stop does not exceed your normal risk.
- Wait for the first candle to close: let the initial spike and spread widening pass, then trade the follow-through or reversal with a defined stop.
- Widen stops proportionally and shrink size: base stops on ATR so position size adjusts automatically.
Remember that stop orders can fill well beyond your price when liquidity is thin. A “$3 stop” can become a $6 loss during a CPI spike.

Frequently asked questions
Why do spreads widen before news?
Liquidity providers reduce or withdraw quotes because of the risk of a sharp move, leaving fewer orders and wider bid-ask spreads.
Should beginners trade news releases?
Generally no. Slippage, spread widening and fast reversals make news trading difficult; many experienced traders avoid it too.
How long does news volatility last?
The most extreme part is usually the first few minutes, but elevated volatility can last for the rest of the session, especially after FOMC press conferences.
Why does price often reverse after the first move?
The initial algorithmic reaction to the headline can be reversed when traders digest details, revisions and context.
