The International Institute for Iranian Studies (Rasanah) has published the Iran Case File (ICF) for April 2026, offering both general readers and researchers a detailed overview and analytical assessment of developments during the period under review. The ICF assesses the Iranian situation and evaluates its evolving dynamics and interactions. It is divided into three main sections: the first examines developments in Iranian domestic affairs, the second addresses Iranian-Arab interactions and the third analyzes Iran’s relations with regional and international powers.
With regard to domestic developments, Iran witnessed significant political, economic, military, social and ideological changes throughout April. Politically, some of the most notable developments included intensifying debate over governance in the post-Khamenei era, growing rivalries among emerging centers of influence following the killing of Ali Khamenei and increasing US skepticism regarding Mojtaba Khamenei’s ability to govern. Economically, the repercussions of the war reportedly contributed to a 13% depreciation of the Iranian toman against the US dollar, record food inflation levels reaching 112.5% and the loss of more than 130,000 direct jobs in addition to approximately 600,000 indirect jobs.
At the military level, the conflict highlighted the role of hybrid and unconventional warfare tactics in exposing vulnerabilities within long-established US military infrastructure in the Middle East, challenging long-held assumptions regarding the invulnerability of US military bases. According to the report, at least 16 US facilities across the region were disrupted, with some temporarily rendered inoperable.
On the social front, the war continued to exert pressure on conditions inside Iran, particularly as infrastructure damage further strained the labor market and contributed to rising unemployment, developments viewed as likely to deepen public dissatisfaction. Ideologically, the report argues that the conflict exposed a broader crisis linked to legitimacy and citizenship, reflected in the contrast between official rhetoric emphasizing national unity and sectarian rapprochement under the new Iranian leadership, and exclusionary practices criticized by some Sunni figures. In this context, the leadership’s efforts to portray expressions of allegiance from Sunni scholars as reinforcing religious and political legitimacy during wartime became a notable aspect of the broader political and ideological debate.
As for Iranian interactions in the Arab world, the month witnessed several notable developments. In Iraq, regional shifts and US pressure influenced the domestic political landscape, contributing to the end of the political deadlock associated with Nouri al-Maliki’s insistence on remaining prime minister. Businessman Ali al-Zaidi was subsequently nominated as prime minister and tasked with forming a new government. In Yemen, the Houthis continue to prioritize their strategic relationship with Iran over Yemen’s domestic interests and national security, with critics arguing that the group has increasingly aligned itself with an overtly Iranian regional agenda centered on advancing Tehran’s strategic objectives.
Regarding Iran’s interactions with international powers, the month was also marked by significant repercussions and tensions. In the context of Israel, Tel Aviv maintained a posture of readiness for the possible resumption of hostilities against Iran amid expectations that the truce with the United States could collapse. The uncertainty surrounding the broader situation was compounded by escalating tensions linked to the crisis over the closure of the Strait of Hormuz, stalled US-Iran negotiations in Islamabad and continued Israeli violations of the ceasefire agreement in Lebanon.
With regard to Russia-Iran relations, Iranian Foreign Minister Abbas Araghchi’s visit to Moscow was interpreted as carrying multiple political messages, including signals of Iranian defiance toward US sanctions and a lack of concern over the security risks facing Iranian political officials during the fragile truce period. At the same time, these developments added further complexity to the broader set of challenges confronting Iran.
