A memorable article in Rolling Stone referred to Goldman Sachs as a “vampire squid,” in large part because of all of the bank’s alumni in high-level government positions.

Fair or not, the bank does seem to have a hold at the Federal Reserve. The last three appointments to the Federal Reserve are all former Goldman officials GS, -2.87% —Patrick Harker, the new president of the Philadelphia Fed; Robert Kaplan, the new president of the Dallas Fed; and now, Neel Kashkari, the new president of the Minneapolis Fed.

They join Bill Dudley, president of the New York Fed, as Goldman Sachs officials turned members of the Federal Open Market Committee, which votes on interest rates. Dudley gets a vote in every FOMC meeting, while the other regional Fed presidents rotate.

These officials are selected by the boards of the regional Fed banks, though they’re also approved in Washington by the Federal Reserve Board.

In announcing the decision, the Minneapolis Fed highlighted Kashkari’s experiences at Pimco, running for governor of California and overseeing the Troubled Asset Relief Program for the U.S. Treasury before noting his stint at Goldman as a vice president.

Their Goldman background may prove relevant for the Fed’s important role in regulating banks, though the lead Fed official on regulation, Gov. Daniel Tarullo, hasn't worked for any of the major investment banks.

It isn’t evident that the Goldman Sachs experience influences the Fed members on interest rates. Dudley is a noted dove at the Fed, while the interest-rate stance of both Harker and Kaplan is unknown at this point.

Kashkari, in interviews while at Pimco, said so-called quantitative easing, which involves the purchase of government bonds by a central bank, did more for markets than for the economy.

Then again, he tweeted out former Treasury Secretary Larry Summers’s article, which was critical of the argument that overly easy monetary policy reduces business investment, as well an op-ed from former Federal Reserve Chairman Ben Bernanke arguing the central bank saved the U.S. economy.
