The evidence gathered is suggestive but not sufficient to verify the claim as stated. Search results surfaced IMF materials on liquidity stress and financial stability, including the IMF's Global Financial Stability Report, but I could not successfully fetch the relevant IMF pages to inspect their text. The search snippet for Arab News indicates the IMF warned that prolonged Middle East conflict could increase financial stability risks, which is directionally consistent with the claim, but that is a secondary-source snippet rather than a validated primary source. The referenced X post at https://x.com/x/status/2044090554452193776 also could not be fetched. Because no directly validated IMF source in this run confirms the precise wording about ongoing Middle East conflicts triggering market dysfunction and liquidity stress, the claim remains unverified.
