Great question. I believe you're absolutely right that if you really want to trace this notion back to its roots, you'll find those roots in the classic "Jewish banker" stereotype supported by antisemites. However, I think there's a case to be made that the 1992 campaign of Pat Buchanan for the Republican presidential nomination that year is a good landmark for this idea coming out into the open, at least in the United States.

Before 1992, the Soviet Union was the great bugaboo of the American far-right. Before Buchanan, the John Birch Society of the 1950s and 1960s was staunchly anti-globalist, but it couched its arguments in terms of the need to fight Marxism and the spread of communism. When it attacked the Civil Rights movement, it did so from the position that the movement represented Marxist influence in the United States. In some of its most famous propaganda, the Birch Society attempted to convince Americans that John F. Kennedy was a traitor to the United States. Fliers to that effect were distributed in Dallas shortly before Kennedy's assassination.

Despite its profoundly conservative beliefs, Birch Society members attempted to build a wall to block anti-semites from joining. Antisemitism is frequently found among extreme conservative and liberal ends of the political spectrum, and the Birch Society attempted to prevent antisemitism from spreading within the society, because society members knew that such beliefs would marginalize the movement. They have had mixed success in preventing that spread.

In any event, I feel that the key moment in our discussion is the fall of the Soviet Union. With the threat of Marxism gone, the Birch Society and far-right groups began focusing on the United Nations to a greater degree. The Birch Society had always opposed the United Nations, believing it to be a Marxist tool, but the spectre of the New World Order began to feature prominently in America's political fringes.

As Michael Barkun writes in A Culture of Conspiracy: Apocalyptic Visions in Contemporary America, "In broad outline, New World Order theory claimed to provide an overarching explanation for contemporary politics by fitting all events into a single scenario: a diabolically clever and unscrupulous secret organization was in the process of seizing control of the world."

This fits neatly into the antisemetic stereotype that a cabal of Jewish bankers controls the world.

On Dec. 30, 1991, William F. Buckley devoted the entire issue of National Review to the topic of anti-semitism. This remarkable fact came about because the Gulf War had deeply divided American conservatives. Some, including Pat Buchanan, believed that the war did not serve America's interests and benefited Israel more than the United States. The mainstream conservative belief was that the United States needed to go to war.

Buchanan, who announced his run for president about the time the issue was published, attempted to run as a political outsider, bashed Japan's "predatory trade policies," declaimed the idea of a trade deal with Mexico (what would become NAFTA), said the U.S. should withdraw from the World Bank and International Monetary Fund, and didn't want the United States to loan billions in housing assistance to Israel.

As the New York Times wrote in February 1992, "The core of Mr. Buchanan's message is that with the end of the cold war the prevalent force in the world today is nationalism. He argues that with countries like Japan centering their policies on their own national economic interests, the United States would be foolish to adopt purely free-trade practices or surrender authority to multinational agencies."

Combined with the allegations of anti-semitism coming from people who might have been Buchanan's allies on the conservative side of American politics, I think there's a solid case to be made that his campaign has many of the elements of what you're looking for.
