The Credit limit is a plan by the Institute for Trade and Welfare and the Science Institute to set a defined value to the credit. Since there is a limited amount of matter and energy in the observable universe, it follows that there should be a limited amount of economic value to it. Information itself can generate value, but this can be accounted for by Bose Fin's Information-Entropy calculation, which shows that the value of information is comparable to the energy used to generate it.
Currently, antimatter and matter can be synthesized from energy and takes 1161 credits per gram most efficiently. Matter fabrication can also be performed, but at limited scales. As the Science Institute moves to advance these two technologies, the plan is to meet the gram equivalent of matter at 1000 credits. Thus, the trade of the Blobverse will be backed by mass-energy conversion.
