I en tale til Underhuset, tilskyndede Labour lederen Parlamentet til at tage forholdsregler i interaktionen med institutioner der yder "vital infrastruktur" til terrorgrupper i Syrien og Irak.
Corbyn sagde at en af de vægtigste måder vi kan stoppe IS i at fungere, er at afskære den fra sine resourcer, og i det et forslag til EU om at spille en rolle i at kvæle organisationen.
"Tydeligvis vil en afgørende måde at bekæmpe ISIL være at afslære den fra sin finansiering, dens våbenleveringer og sin handel," sagde Corbyn under "Spørgsmål til ministeren" (PMQ).
Kan jeg presse Premierministeren til at forsikre os i at vores allierede i regionen, i alle lande i regionen, vil gøre alt hvad de kan for slå ned på individer og institutioner i deres lande, der hjælper ISIL med dens vitale infrastruktur?
"Vil han (Cameron) gennem den Europæiske Union og andre fora, hvis nødvendigt, overveje sanktioner mod de banker og selskaber og hvis nødvendigt lande, der vender det blinde øje til dem der handler med ISIL, der yder dem bistand i deres arbejde?", spurgte han.
Premierminister David Cameron svarede ved at sige at England allerede spliller en "ledende rolle" i at udsulte IS fra finanser, men advarede at det ikke ville være den eneste britiske respons til ekstremist-gruppen.
"Vi kan ikke forevigt undvige spørgsmålet om hvordan vi degraderer og ødelægger ISIL, både i Irak og Syrien,... ja, gå efter pengene, afskær deres forsyninger, men gør det ikke til en erstatning for den handling der kræves for at slå ned på disse folk hvor de er," sagde han.
Comment: Der kan ikke laves penge på at blokere finansiering og samtidig gå imod Vestens uudtalte ønsker, for ikke at tale om at sanktioner vil være sig deres egen investeringer i mellemøstlige proxy-kriger! Det er bedre at lave penge på krig, ifølge Cameron.

Corbyn has previously criticized Saudi Arabia for failing to stop resources and money being sent to IS.
"Saudi Arabia, maybe not at government level, but certainly at aid-level, has been providing support to ISIL," he said.
Cameron is currently preparing the House of Commons for a vote to extend British airstrikes from Iraq into Syria.
The prime minister has said he will not hold the vote until he is guaranteed enough backing to pass it, but it is thought the terror attacks in Paris last week will have bolstered support for more airstrikes.
At the G20 summit in Turkey on Monday, Cameron expressed his interest in working more closely with Russia, which is already launching airstrikes in Syria against IS targets.
Speaking in the House of Commons on Tuesday, Cameron said the attacks in Paris on Friday justify a "full spectrum approach," including military power, counter-terrorism action and countering the narrative of extremism.
"It is in Syria, in Raqqa, that ISIL has its headquarters and it is from Raqqa that some of the main threat against this country are planned and orchestrated. Raqqa, if you like, is the head of the snake.
"Over Syria we are supporting our allies the US, France, Jordan and the Gulf countries with intelligence, with surveillance and with refueling. But I believe, as I have said many times before, we should be doing more. We face a direct and growing threat to our country and we need to deal with it, not just in Iraq, but in Syria too."
