Launched in 2012 as SALT Singapore and later changed to SALT Asia, the event sought to capitalize on "new opportunities ... created by the growth in the Asian markets and the shift in global trade," as Scaramucci put it May of the same year. The Singapore edition attracted about 1,000 people each year—about half that of Las Vegas—with the third installment set for Oct. 21-24 at the Marina Bay Sands hotel, a gleaming boat-shaped jewel of the city-state.
But SkyBridge has quietly communicated with conference partners that the event could be the last in Singapore, according to people familiar with the situation.
SkyBridge is considering alternate Asian locations for the 2015 conference, including Tokyo, Hong Kong, Macau and Seoul, according to a person with direct knowledge of the situation.
Separately, SkyBridge is considering expanding the SALT conference brand to other countries thanks to multiple inquiries from aboard. The firm has considered or been approached by groups from Brazil, Argentina, Abu Dhabi, Dubai, Turkey, Spain, Monaco and Switzerland, according to the person.
"We are committed to SALT in Asia," Victor Oviedo, partner and head of business development for SkyBridge, said when asked about a potential shift out of Singapore and into other countries. "We're always evaluating how to expand the conference. But at this point there's nothing concrete planned outside of the U.S. and Asia events."
Oviedo maintains that SALT Singapore has been a success.
The original goal was to have between 400 and 500 attendees; around 1,000 have shown up each year and the same amount is expected in 2014. Speakers last year included recent former Treasury Secretary Tim Geithner and Jean-Claude Trichet, former president of the European Central Bank.
"The Singapore events have exceeded our expectations," Oviedo said.

Asian hedge fund industry observers say that SALT is one of the best hedge fund events in a region with few of them. But Asia can be a difficult marketplace as it's a relatively small one for the hedge fund industry.
Of $2.34 trillion in global hedge fund assets as of July 2013, just $91 billion were based in Asia, compared with $1.69 trillion with U.S. firms, according to data and news service HedgeFund Intelligence. Hong Kong is the largest Asian center for hedge fund firms, followed by Singapore.
The biggest pool of money—mainland China—is also largely out of play due to government restrictions on investing abroad.
SALT is also costly for most attendees. Tickets to the 2013 Singapore conference cost between nothing for institutional investors and $5,495 for industry service providers, according to marketing materials. Late registrants paid more, including $795 for institutional investors.
Speaking roles can cost much more. Some elite fund managers speaking on panels get in for free, but others, including fund managers, investment banks and service providers, pay tens of thousands of dollars for sponsorship packages.
One hedge fund firm was approached about packages between $35,000 and $50,000 to attend and speak in Singapore last year. The $50,000 option included three employee and six client tickets, plus a speaking role and a "VIP" evening event pass, according to an employee of the firm who asked not to be named.
Those prices are similar to Las Vegas. Hedge fund managers wishing to speak at the upcoming conference usually pay between $30,000 and $65,000 for a speaking role, according to marketing materials obtained by CNBC.com. The large investment banks and asset managers who usually take the conference's lead sponsorships are offered packages that range from $35,000 to $100,000 or more.
Top sponsors for Las Vegas this year include Bank of America, Fortress Investment Group, Wells Fargo and Paulson & Co. CNBC is a media partner for the event.

Regardless of what happens with Singapore or if SALT expands to the Middle East, Latin America or Europe, SkyBridge is looking forward to Las Vegas May 13-16.
