US sanctions have caused significant technical and financial challenges for Iran. Initially, disruptions were reported regarding access to banking websites, the Shaparak electronic payment network, and news outlets due to restrictions on SSL security certificates. In response, the Central Bank of Iran and 15 domestic banks, including Mellat, Melli, and Saderat, have implemented domestic security certificates to maintain secure connections.

To manage financial restrictions, Iranian institutions have utilized layered transaction methods. Documents from late 2022 to mid-2023 indicate that Parsian Exchange has been used to obscure money trails through multiple banks, companies, and trustees. These strategies often involve transferring foreign currency from oil and petrochemical exports through accounts in the United Arab Emirates, China, and Hong Kong to settle payments for importers. Many Iranians also rely on informal networks of cross-border currency exchangers and intermediary firms to bypass restrictions, albeit with higher fees and increased complexity.

Recent developments show Iran expanding its methods to bypass energy-related blockades. Despite US naval efforts, Iran has successfully exported liquefied petroleum gas (LPG) and aviation fuel. Maritime intelligence indicates these shipments are concealed via ship-to-ship transfers, frequently occurring off the coast of Oman. Analysis from United Against Nuclear Iran (UANI) noted at least eight gas tankers carrying Iranian LPG departing the Gulf of Oman since mid-July. Furthermore, satellite imagery has identified a tanker carrying Iranian aviation fuel arriving in Myanmar, a country subject to US sanctions on its aviation fuel sector. While these volumes represent a small fraction of previous energy exports, they demonstrate a method for bypassing sanctions that have largely halted crude oil exports. U.S. Central Command (CENTCOM) continues to describe the blockade as ‘impenetrable,’ noting that U.S. forces have intercepted numerous vessels and forced others to change course.
