1. 01۱۹۸۹First Post-War Five-Year Plan (Rafsanjani reconstruction)قوت ارتباط

   Rafsanjani government begins post-war economic liberalization and reconstruction planning after Khomeini's death (June 1989).

   چرایی این پیوند: External debt more than tripled from $6.5bn (1989) to $23.4bn (1993, the series' historic peak) as the reconstruction plan's import-led investment boom (see the capital formation chart) was financed substantially through short-term foreign trade credit -- a widely documented episode in Iran's economic history and the direct origin of the mid-1990s debt-service crisis.

   ملاحظه: None substantial -- this is one of the best-documented policy-to-debt links in Iran's postwar economic history.

2. 02۲۰۱۲SWIFT 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: The reported external debt stock dropped 56.7% in a single year, from $17.3bn (2011) to $7.5bn (2012), as sanctions cutting Iran off from international financial channels sharply curtailed new borrowing.

   ملاحظه: A 57% one-year drop in a debt STOCK (not a flow) is unusually large for pure new-borrowing effects; it likely mixes genuine deleveraging with data-reporting or valuation discontinuities as sanctioned-era statistics became harder to compile -- treat the precise magnitude with real uncertainty.

3. 03۲۰۱۹US ends oil waivers -- push to zero exportsقوت ارتباط

   The Trump administration announces it will not renew sanctions waivers for the countries (China, India, Japan, South Korea, Turkey and others) still importing Iranian crude after 2 May 2019, aiming to cut Iran's oil exports to zero; exports fall from over 2.5 million bbl/day pre-sanctions to under 1 million bbl/day.

   چرایی این پیوند: External debt rose 90.5% in 2021 (from $5.4bn to $10.3bn) after several years of sanctions-constrained borrowing. This may reflect a widening financing gap as oil exports were squeezed toward zero and COVID-19 compounded fiscal pressure, but no single dated policy event in this project's timeline pins down the cause.

   ملاحظه: No specific timeline.csv event directly explains this jump; it may also reflect data revision or accumulated import-financing arrears rather than one identifiable policy action. Confidence kept low given the absence of a clean matching event.
