Crypto and FX Markets React Instantly to Fed Decisions and Tweets, Report Reveals

One key aspect of market efficiency is its ability to react instantly to major events, particularly in cryptocurrency and foreign exchange (FX).

Whether it's a sudden tariff announcement or a tweet from a high-profile political figure, these markets adjust in real-time, often showing remarkable similarities in their speed and depth.

This is according to a recent study by LMAX Group, dubbed Millisecond Reactions to Market Shocks, which highlighted how quickly markets respond to major global events. The report compared the real-time movements of cryptocurrency and FX markets.

BTC/USD and EUR/USD

Key events such as Federal Reserve rate decisions, political announcements, and even fake news headlines have demonstrated how both markets can react almost instantaneously, with moves often measured in milliseconds.

“Our previous report in November 2024 highlighted the pace at which FX markets—the most liquid market in the world—price in key information immediately following US macroeconomic data releases,” commented Bilal Hafeez, the CEO and Head of Research at MacroHive, and the co-author of the report.

“Our latest findings show BTC’s correlation to FX markets, the depth of markets even around political events like Trump’s social media posts.

For instance, examining price fluctuations just seconds after a Fed decision or a political tweet shows a significant portion of the market’s price action, often allowing for predictive insights that can inform future trades.

An in-depth look at the Fed's rate decisions reveals that both BTC/USD and EUR/USD markets respond almost immediately after the announcement.

The report pointed out that while both markets exhibit similar patterns of initial reaction, their volatility levels differ. Cryptocurrencies like Bitcoin Bitcoin While some may still be wondering what is Bitcoin, who created Bitcoin, or how does Bitcoin work, one thing is certain: Bitcoin has changed the world.No one can remain indifferent to this revolutionary, decentralized, digital asset nor to its blockchain technology.In fact, we’ve gone a long way ever since a Florida resident Laszlo Hanyecz made BTC’s first official commercial transaction with a real company by trading 10,000 Bitcoins for 2 pizzas at his local Papa John’s.One could now argue that While some may still be wondering what is Bitcoin, who created Bitcoin, or how does Bitcoin work, one thing is certain: Bitcoin has changed the world.No one can remain indifferent to this revolutionary, decentralized, digital asset nor to its blockchain technology.In fact, we’ve gone a long way ever since a Florida resident Laszlo Hanyecz made BTC’s first official commercial transaction with a real company by trading 10,000 Bitcoins for 2 pizzas at his local Papa John’s.One could now argue that Read this Term tend to experience higher volatility compared to traditional FX pairs like EUR/USD.

Political Events and Their Market Impact

Political events, particularly those linked to the actions of influential figures like US President Donald Trump, have a profound effect on markets. One such instance was Trump's announcement on February 3, 2025, about pausing tariffs on Mexico and Canada.

"Clients are increasingly relying on quality data to drive trading decisions across asset classes. We have leveraged on MacroHive’s ability to analyse the markets to jointly release this report to offer unique and predictive insights on the markets using millisecond LMAX Group FX and cryptocurrency order book data,” added Arun Sundaram, the Head of Market Data, LMAX Group, also a co-author in the report.
