What would be a an accurate metric of the real economy without the financial services sector? A youtube video by RT predicts that China's economy will surpass the US in GDP by 2028. The conclusion was a result of projections of GDP growth for both nation's economies. According to anearlier youtube video by CBS News, China already passed the US in purchasing power, another economic metric, according to the IMF, back in 2014.
Due to the size of China's manufacturing sector, which is the sector that actually produces real products and stable jobs, it seems that China has long ago passed the US in the real economy of real goods and services.  Is there a metric of the real economy without the obfuscations of the so-called financial services sector which includes banking, insurance, securities, intangible assets, derivatives, incomes derived from interest and speculation, etc?   In other words, a gross measure of the sum of transactions of tangible goods and services, not including any financing for the tangible goods and services.  Preferably the metric would be in tons of gold, silver, or other real substances of intrinsic value, not in US Dollars or other fiat currency.  Thank you.
This question is difficult to answer. You can start by simply finding the value of the manufacturing sector of any country's economy. But this quickly becomes very hard to define. Let's take Tesla for instance, Tesla manufactures cars, but they also are deeply involved in software engineering for their company. Is Tesla a software firm or a manufacturing firm?
The question gets even more complicated when you take a company which manufactures some of its own supply chain and also has investments in other companies, which will include basically every manufacturer in America, because almost any firm in the world will diversify its holdings when it has extra cash on hand.
The best answer you have will be to look at the latest GDP report and then subtract whichever sectors you don't consider &quot;real&quot;... which is available here for the United States: https://www.bea.gov/data/gdp/gross-domestic-product
But given how many large companies have financial investments as part of their corporation you have to have a good definition for what a &quot;real economy&quot; is in reality, which is not an easy question in your terms. Ultimately it is all real, just as real as the value of intellectual property such as patents or copyrights.
If you don't want to measure it in dollars you can always use xe.com to calculate the value in gold. Nobody measures economic data in gold, silver, or oxen nowadays.
