The Four Horsemen of Banking (Bank of America, JP Morgan Chase, Citigroup and Wells Fargo) own the Four Horsemen of Oil (Exxon Mobil, Royal Dutch/Shell, BP Amoco and Chevron Texaco); in tandem with Deutsche Bank, BNP, Barclays and other European old money behemoths. But their monopoly over the global economy does not end at the edge of the oil patch.
According to company 10K filings to the SEC, the Four Horsemen of Banking are among the top ten stock holders of virtually every Fortune 500 corporation.
So who then are the stockholders in these money center banks?
This information is guarded much more closely. My queries to bank regulatory agencies regarding stock ownership in the top 25 US bank holding companies were given Freedom of Information Act status, before being denied on “national security” grounds. This is rather ironic, since many of the bank’s stockholders reside in Europe.
One important repository for the wealth of the global oligarchy that owns these bank holding companies is US Trust Corporation – founded in 1853 and now owned by Bank of America. A recent US Trust Corporate Director and Honorary Trustee was Walter Rothschild. Other directors included Daniel Davison of JP Morgan Chase, Richard Tucker of Exxon Mobil, Daniel Roberts of Citigroup and Marshall Schwartz of Morgan Stanley. 
J. W. McCallister, an oil industry insider with House of Saud connections, wrote in The Grim Reaper that information he acquired from Saudi bankers cited 80% ownership of the New York Federal Reserve Bank- by far the most powerful Fed branch- by just eight families, four of which reside in the US. They are the Goldman Sachs, Rockefellers, Lehmans and Kuhn Loebs of New York; the Rothschilds of Paris and London; the Warburgs of Hamburg; the Lazards of Paris; and the Israel Moses Seifs of Rome.
CPA Thomas D. Schauf corroborates McCallister’s claims, adding that ten banks control all twelve Federal Reserve Bank branches. He names N.M. Rothschild of London, Rothschild Bank of Berlin, Warburg Bank of Hamburg, Warburg Bank of Amsterdam, Lehman Brothers of New York, Lazard Brothers of Paris, Kuhn Loeb Bank of New York, Israel Moses Seif Bank of Italy, Goldman Sachs of New York and JP Morgan Chase Bank of New York. Schauf lists William Rockefeller, Paul Warburg, Jacob Schiff and James Stillman as individuals who own large shares of the Fed.  The Schiffs are insiders at Kuhn Loeb. The Stillmans are Citigroup insiders, who married into the Rockefeller clan at the turn of the century.
Eustace Mullins came to the same conclusions in his book The Secrets of the Federal Reserve, in which he displays charts connecting the Fed and its member banks to the families of Rothschild, Warburg, Rockefeller and the others. 
The control that these banking families exert over the global economy cannot be overstated and is quite intentionally shrouded in secrecy. Their corporate media arm is quick to discredit any information exposing this private central banking cartel as “conspiracy theory”. Yet the facts remain.
The House of Morgan
The Federal Reserve Bank was born in 1913, the same year US banking scion J. Pierpont Morgan died and the Rockefeller Foundation was formed. The House of Morgan presided over American finance from the corner of Wall Street and Broad, acting as quasi-US central bank since 1838, when George Peabody founded it in London.
Peabody was a business associate of the Rothschilds. In 1952 Fed researcher Eustace Mullins put forth the supposition that the Morgans were nothing more than Rothschild agents. Mullins wrote that the Rothschilds, “…preferred to operate anonymously in the US behind the facade of J.P. Morgan & Company”. 
Author Gabriel Kolko stated, “Morgan’s activities in 1895-1896 in selling US gold bonds in Europe were based on an alliance with the House of Rothschild.” 
The Morgan financial octopus wrapped its tentacles quickly around the globe. Morgan Grenfell operated in London. Morgan et Ce ruled Paris. The Rothschild’s Lambert cousins set up Drexel & Company in Philadelphia.
The House of Morgan catered to the Astors, DuPonts, Guggenheims, Vanderbilts and Rockefellers. It financed the launch of AT&T, General Motors, General Electric and DuPont. Like the London-based Rothschild and Barings banks, Morgan became part of the power structure in many countries.
By 1890 the House of Morgan was lending to Egypt’s central bank, financing Russian railroads, floating Brazilian provincial government bonds and funding Argentine public works projects. A recession in 1893 enhanced Morgan’s power. That year Morgan saved the US government from a bank panic, forming a syndicate to prop up government reserves with a shipment of $62 million worth of Rothschild gold.
