Social Media Sentiment & Interest Rate Changes: New Factor for Central Banks

Interest rate changes have traditionally been a closely watched indicator that affects everything from government bonds to mortgage rates and credit cards. The decisions related to interest rates are often made by central banks after considering a host of economic factors. However, as we move further into the age of social media pervasiveness, one might be considering a novel question: Can social media sentiment and discussions predict changes in interest rates? At the very least, can they become a variable seriously considered by central banks when making interest rate decisions? This article aims to delve deep into this topic, evaluating the potential, the challenges, and the ethical considerations involved.

Traditional Framework of Interest Rate Decisions

Central banks around the world use a wide range of economic indicators to determine interest rate changes. These typically include inflation rates, employment numbers, GDP growth, and others. The decisions are made by committees that deliberate extensively before reaching a conclusion.

Investor sentiment in traditional financial markets is also a consideration factor in interest rate deliberations and decisions. Yet, social media sentiment, while already being used by institutional and retail investors to analyse markets, is not yet an element of the interest rate decision framework.

Emergence of Social Media Sentiment

Social media platforms have become more than just spaces for personal interaction; they are also marketplaces of ideas, opinions, and predictions about various subjects, including economics and finance. Detailed, high-volume discussions of the cryptocurrency, forex, commodity, and stock markets are available via social platforms like X, Reddit, Seeking Alpha, and more.

With hashtags, trending topics, and the sheer volume of discussions, social media holds a sea of information that could theoretically be tapped to gauge public sentiment on interest rates.

Back in 2021, we realised the potential to turn this massive volume of discussions into useful sentiment gauges for investors. That’s how ZENPULSAR was born. Today, we are supplying social sentiment data and insights to a wide range of institutional and retail investors of all sizes and segments.

While the use of social media data to evaluate investor sentiment has become ubiquitous, national central banks remain probably the only big market entities that seem to stick to the archaic ways of using only traditional market sentiment measures.

And it is time for them to spot the oversight and use social media sentiment in their decision-making process.

Potential Ways Social Media Could Impact Interest Rates

Social media sentiment can serve central banks as an interest rate decision variable in numerous ways:

1. Predicting Consumer Behavior

One way social media could potentially predict interest rate changes is through the sentiment and conversations around consumer spending. For example, if there is a noticeable uptick in conversations suggesting that people are less willing to spend, this could serve as a useful insight on overall consumer sentiment.

2. Understanding Business Sentiment

Businesses often express their views on economic conditions through official social media channels. Analyses of these sentiments could provide insights into business investment and employment plans, both of which are factors in interest rate decisions. LinkedIn, X, and to a lesser degree Facebook, are the primary platforms where businesses are sharing their plans, aspirations, and views with the public.

3. Political Discussions

Though central banks aim to be independent, the political climate can often influence economic policies, including interest rates. Social media is increasingly being used as a platform for political discussions, and tracking the sentiment around these could offer clues into forthcoming economic decisions.

In particular, Elon Musk’s formerly Twitter, now rebranded to the laconic X, is a major playground for governments, national banks, high-profile politicians, and other significant political entities to voice their opinions and share information.

Consideration Factors

Using social sentiment and discussions for interest rate decisions comes with its own set of challenges and consideration factors. Often, these challenges are overcome via using advanced approaches to social data collection, processing, and analysis. For instance, our social media analytics platform, PUMP, uses advanced NLP algorithms to source and process social data.

When considering social media data, central banks need to take into account the following factors:

1. Data Noise

Social media is filled with a variety of opinions, and not all are educated or informed. This can create significant 'noise' in the data. The more advanced and sophisticated social analytics tools are typically much better at filtering out the noise.

2. Ethical and Privacy Concerns

Using social media data for something as significant as setting interest rate changes raises questions about data privacy. This is something that is currently being actively considered by governments around the world. Comprehensive AI legislation that protects consumer privacy has not been fully implemented in any large economy. Such legislation is expected to address the issue of data privacy and make social sentiment data more interesting to central banks.

3. Time Sensitivity

Central banks typically consider a range of immediate, short-term, and long-term factors in their interest rate decisions. Therefore, when evaluating social sentiment, it is important for the banks to analyse both the existing discussions as a gauge of the current mood and past data, which is often predictive of longer-term behavioural trends. For instance, when we analyse financial assets using PUMP, we frequently notice that sentiment and discussions that occur months prior predict the assets’ market performance later on.

Social media has become pervasive in the consumer, business, and political domains. With the wealth of data and insight contained on social media platforms, the time has arrived for central banks to start integrating social sentiment into their decisions. Our prediction is that this process is starting up. Soon, you might hear a mention of social sentiment uplift when a central bank governor justifies another unloved interest rate hike decision.
