It’s 8:20 am Eastern Time. A number will drop in ten minutes and change the morning for millions of traders across the country before they’ve even had time for the first coffee of the morning from Dunkin’ Donuts.
This is the one day of the month when you have to meticulously plan your route to work to make sure that you and your phone are both online at the right time. It’s CPI day, and your forex trades are sitting in limbo until the data is clear and the markets begin to react. You and many others, the majority of whom are all under the age of 35, are staring at your screen waiting for what’s to come.
What even is CPI, and why does forex care?
Alright, let’s break this down a little before we go any further. CPI is the Consumer Price Index. It is the monthly report issued by the US government that reports on everyday prices. Groceries, rent, fuel: you name it, it’s covered by this one report. When prices rise faster than expected, inflation is running hot. The opposite means inflation is running cool.
America’s central bank, the Federal Reserve, controls the US interest rates. When inflation runs hot, the Fed raises rates to try to cool it down. But higher US rates make the dollar more attractive. More demand equals a stronger dollar.
A stronger dollar moves every US dollar currency pair, and by now you will know: all major forex currency pairs include USD, whether it be traded with Euros, pound sterling, or yen. This chain reaction isn’t new, either. The Fed’s own data shows it plays out across decades of history. So, the big question now is: what does that actually look like in real time? Here’s what happens in the 60 seconds that immediately follow the CPI number drop.
Gone in 60 seconds: what happens immediately after an inflation report?
In the first 500 milliseconds, algorithms read the number before a single human can blink. Prices move between 20 and 50 pips in a single tick. Pips are the unit for measuring price movement, like centimeters on a ruler: tiny but meaningful.
Then, in those remaining moments of the first ten seconds, spreads explode. A spread is the gap between the buy and sell price that your broker quotes. It’s normally tiny, but during a news release, it will look like a chasm. EUR/USD jumps from 0.2 to 15 pips in an instant – and that gap comes straight out of any existing trades. The liquidity vacuum has opened: the moment when both buyers and sellers temporarily leave the market, so the prices are left to swing wildly without anything to anchor them.
Then, you breathe. Human traders are now beginning to act. Between 10 and 30 seconds, momentum either builds or reverses. It depends entirely on whether CPI beat, missed, or matched expectations. For the remainder of the first minute, you’ll see traders who positioned before the release start to take profit or cut losses. This is when the second wave of volatility hits. 30% of the entire hourly price movement after a major release occurs in these first two seconds. So, if all of that happens in under a minute, what’s a beginner on their trading app supposed to do about it?
What this means for a beginner
If your gut reaction says to you that you shouldn’t trade the release itself, you’re absolutely right. But the aftermath? That’s fair game. Algorithms will always win the first two seconds, and no user on their mobile app is going to be able to compete with that, and honestly? That’s absolutely fine.
The real, tradeable window for beginners is the sustained trend that follows in that final phase of the initial half an hour. Between 15 and 30 minutes after the release, the dust settles, and a clear direction emerges. This is when you act. A fantastic resource to give you a chance to learn strategy before risking real money is BabyPips, which will give you a free starting point to understand market movements.
Truthfully speaking, not all brokers handle volatility the same way. Execution speed and spread size are two variables that matter hugely in those seconds following an incident that causes high volumes of market movement. A bad broker, whose platform doesn’t execute your trades quickly enough with its bulky backend and unreactive server speed, will cost you money before you’ve even been able to act on your decision.
The best forex brokers are those with a lightweight infrastructure that can execute trades within a fraction of a second, and which have a transparent policy on how it operates during periods of market volatility.
The bigger picture: one report, weeks of movement
At the end of the day, this one report will cause weeks of movement. A CPI report is dropped monthly, so it shifts trading direction for four weeks at a time. Trades shouldn’t be reactive; they should be planned and well thought through before execution. A month is a long time. You will still have a chance to capitalize, even when you don’t react in the first minute to the report being released.
Each month, you’ll see either a rate hike, when the Fed raises interest rates: a stronger dollar, more expensive borrowing; or a rate cut, the opposite: lower interest rates to stimulate spending, which typically weakens the dollar. As a trader, you can either be bullish and expect the price to rise or bearish and expect it to fall.
The mental gymnastics to think through is that if there’s a hot CPI, you can market bets on the rate hike because the dollar will strengthen for days, not just hours, after the announcement. If the CPI is cool, then do the opposite: market your bets on the rate cut because the dollar is weakening in the days that follow the release.
The reason the market is so volatile ahead of and following each CPI release is that everyone is asking the same question: Is the Fed raising, holding, or cutting? Every single trader, institutional or retail, is pricing in the same answer simultaneously. Algorithms will react faster than we do, but we’re all following the same goal.
One single crucial piece of advice to take away from this outline is that you should be using the built-in economic calendar that your forex platform provides. If there isn’t one, that’s a red flag, and you can bookmark the Bureau of Labor Statistics release schedule instead while you quickly check the list of best forex brokers to find a suitable alternative.
The falling of dominoes is an understandable sequence of events
So the market didn’t randomly spike. It was a sequence of events and a logic that caused the falling of the dominoes that you saw play out in under a minute. Now that you know how it works, you can better understand how to watch the chart react ahead of next month’s CPI release. Because that’s the thing with monthly releases. There’s always another one around the corner for you to learn from, react to, and try to capitalize upon.
When you’re ready to put this knowledge to work, start with the right platform. Half the battle is having the technology beneath your app to execute your strategy at the right time.
