1. 01۲۰۱۲SWIFT disconnection and oil-export sanctionsقوت ارتباط

   Major Iranian banks cut off from SWIFT messaging; US NDAA sanctions target foreign purchasers of Iranian oil, triggering a sharp rial depreciation through 2012-13.

   چرایی این پیوند: Net energy imports (deeply negative because Iran is a large net energy EXPORTER) narrowed sharply from -64.6% of energy use (2011) to -37.0% (2012), the single largest one-year narrowing in the series, as the SWIFT disconnection, EU oil embargo and NDAA sanctions cut into the oil/gas export volumes that make this ratio so negative in the first place -- a distinct angle on the same 2012 sanctions shock visible in this database's oil-production and export-revenue charts, here expressed as a shrinking net-energy-exporter position rather than a raw export-dollar decline.

   ملاحظه: This indicator mixes both the numerator (energy trade) and the denominator (total domestic energy use, itself rising over this period) -- part of the narrowing could reflect growing domestic energy consumption rather than purely falling exports, though the timing strongly suggests the export channel dominates.

2. 02۲۰۱۸US withdraws from JCPOAقوت ارتباط

   President Trump announces US withdrawal from the JCPOA and reimposition of sanctions after 90/180-day wind-down periods (effective Aug 7 and Nov 5, 2018).

   چرایی این پیوند: The ratio narrowed further from -49.8% (2018) to -22.1% (2020), the least negative (smallest net-exporter position) in the entire 1990-2022 series, as oil-export sanctions pushed toward zero cut deeply into the export side of Iran's energy balance.

   ملاحظه: None substantial beyond the same numerator/denominator caveat noted in the companion 2012 row above.
