**Russia and Ukraine also missed a diplomatic meeting and Russia's central Bank made no policy Change**

Negotiations between the United States and Iran did not produce a Hormuz agreement by mid-September. Parallel diplomatic efforts between Russia and Ukraine also stalled, with no meeting taking place by the mid-September deadline. In Moscow, the Bank of Russia announced no policy adjustment during September, maintaining the existing monetary stance.

Talks aimed at a September 15 resolution fell short, and the parties failed to sign any binding accord. Subsequent planning for a follow-up round did not materialise, and no venue was confirmed for a meeting before the end of September. The absence of a scheduled conference eliminated a near-term forum for de-escalation in the region.

Commercial vessels continued to avoid the narrow waterway, and reported transits remained below pre-crisis levels. Shipping companies cited security concerns and the lack of a US-Iran understanding as reasons for rerouting. The sustained disruption persisted through September 30, the latest date for assessing traffic normalisation.

No bilateral meeting was recorded in that period, extending the diplomatic impasse that began after the conflict's escalation. The failure to meet limited any immediate progress on ceasefire or humanitarian arrangements.

The Bank of Russia reviewed its monetary policy during September and chose to keep rates unchanged. Maintaining the status quo left the domestic financial environment stable but offered no stimulus for economic recovery.

## Analysis

The collapse of US-Iran talks leaves the Strait of Hormuz without a de-escalation framework, meaning shipping firms must continue to weigh higher risk premiums when routing cargo. Without an agreement, diplomatic channels remain limited, reducing the chances of a quick restoration of normal traffic levels.

The absence of a Russia-Ukraine diplomatic meeting by mid-September extends the stalemate that hampers negotiations on ceasefire terms and humanitarian corridors. Both sides retain their current positions, which means any progress on prisoner exchanges or reconstruction plans remains on hold. The deadlock also sustains uncertainty for neighboring states that rely on stable security conditions.

By not adjusting rates, the central Bank avoids adding inflationary pressure but also forgoes a potential tool to stimulate growth. The move suggests that policymakers see no immediate need to react to the diplomatic failures surrounding the conflict, but it leaves room for future adjustments should conditions shift.

The uncertainty surrounding future talks means that investors and governments must plan for continued volatility and limited diplomatic progress in the near term.
