Hello, I'm an expert in economics and finance with a particular interest in the global financial system and the circulation of currency. Let's delve into the question of how much cash is there in the world.

Firstly, it's important to clarify what we mean by "cash" and how it's measured. When we talk about the total amount of cash in the world, we're usually referring to the physical currency in circulation, which includes banknotes and coins. However, the concept of money has expanded beyond physical cash to include various forms of electronic and digital money.

The M2 money supply is a measure that includes cash, checking deposits, and easily-convertible near money. It's a broader measure than just cash and provides a more comprehensive view of the money available in an economy. According to the reference you provided, in July 2013, the M2 money supply was approximately $10.5 trillion.

When we narrow our focus to actual notes and coins, the figure is significantly less. The reference suggests that there were about U.S. $1.2 trillion in physical currency circulating globally at that time.

It's crucial to note that these figures are not static. The amount of cash in the world is constantly changing due to various factors, including economic growth, inflation, currency exchange rates, and government policies. Central banks and financial institutions continuously monitor and adjust the money supply to maintain economic stability.

Moreover, the distribution of cash is not uniform across the globe. Some countries have a higher propensity to use cash, while others are rapidly moving towards a cashless society. The advent of digital payment systems and cryptocurrencies is also influencing the way money is used and stored.

Additionally, the concept of cash does not encompass all forms of money. For instance, electronic money, which includes funds held in bank accounts that can be accessed and transferred electronically, is a significant part of the global monetary landscape. The rise of digital currencies and cryptocurrencies is another factor that is reshaping the monetary system.

In conclusion, while the figures from 2013 provide a snapshot of the cash in circulation, the actual amount of cash in the world today is likely to be different and is influenced by a myriad of factors. It's a dynamic and evolving aspect of the global financial system.
