IMF and central banks warn: stablecoins, shipping frictions, and energy shocks are reshaping regional risk—what’s next?

The IMF has warned Nigeria that rising stablecoin usage could weaken naira demand, undercutting monetary policy transmission and complicating efforts to stabilize the currency. The warning lands as Nigeria remains one of the world’s largest crypto markets, meaning stablecoin adoption is not a niche trend but a potentially systemic channel for value transfer. Separately, Maersk is keeping significant cargo restrictions and emergency surcharges across the Persian Gulf even after public signals that the Hormuz area is reopening, underscoring that normalization is incomplete. In parallel, Armenia’s central bank is warning that export restrictions carry economic risks, while an expert cited by TASS argues that breaking with Russia could turn Armenia into an “economic disaster zone” due to the gap between Russian gas pricing and far higher European market levels. Taken together, the cluster points to a broader geopolitical pattern: financial and trade plumbing is being re-routed faster than policymakers can adapt. Nigeria’s stablecoin concern highlights how non-bank settlement rails can dilute central-bank leverage, benefiting users who can arbitrage FX and settlement frictions, while increasing pressure on authorities to defend the naira. The Persian Gulf shipping posture suggests that even when political narratives shift toward reopening, insurers, operators, and compliance regimes still price in security uncertainty, benefiting logistics firms that can charge risk premia while raising costs for importers and energy-linked supply chains. For Armenia, the energy pricing asymmetry described by Krylov implies that geopolitical realignment away from Russia would be immediately costly, shifting bargaining power toward suppliers and away from Armenian consumers and exporters. Market and economic implications span FX, trade flows, and energy-linked inflation. Nigeria faces a potential weakening of naira demand dynamics if stablecoin settlement grows, which can translate into higher FX volatility and tighter financial conditions for banks and importers; the IMF’s framing implies a risk to currency stability rather than a one-off shock. In the Persian Gulf, Maersk’s continued restrictions and surcharges can lift freight rates and raise delivered costs for industrial inputs, consumer goods, and possibly LNG-adjacent logistics, with knock-on effects for inflation expectations in import-dependent economies. Armenia’s export restrictions and gas-price exposure point to a direct risk of higher domestic energy costs and weaker export competitiveness, especially if alternative supply is priced closer to European benchmarks. Meanwhile, the TASS note that Azerbaijan–Russia trade turnover fell about 1.6 times over January–May 2025 signals ongoing trade reorientation that can affect regional commodity flows and payment channels. What to watch next is whether authorities respond with policy measures that either curb stablecoin substitution or deepen regulated FX access, and whether shipping operators gradually unwind restrictions as risk perceptions change. For Nigeria, key triggers include IMF follow-up assessments, central bank guidance on crypto/stablecoin oversight, and observable shifts in naira demand versus stablecoin volumes. For the Persian Gulf, monitor whether Maersk and other carriers reduce emergency surcharges and restrictions, and whether insurers adjust war-risk premiums tied to Hormuz routing. For Armenia, the next signals are the scope and duration of export restrictions, any changes in gas procurement terms, and whether political moves toward “break with Russia” translate into concrete supply contracts that close the pricing gap. Across the region, escalation or de-escalation will likely hinge on security incidents near Hormuz, policy announcements on crypto regulation, and energy-market repricing that can quickly feed into inflation and fiscal stress.

Geopolitical Implications

• 01

  Non-bank settlement rails (stablecoins) can reduce central-bank leverage, strengthening informal cross-border value transfer and complicating sanctions/FX management.

• 02

  Persistent shipping risk premia around Hormuz can become a geopolitical bargaining chip, influencing who can move goods cheaply and who pays for uncertainty.

• 03

  Energy dependency dynamics can constrain foreign-policy maneuvering: Armenia’s cost gap implies that geopolitical realignment away from Russia has immediate economic costs.

• 04

  Trade turnover declines between Russia and regional partners indicate ongoing reconfiguration of economic ties under sanctions, logistics frictions, and payment constraints.

Key Signals

• —Nigeria: regulatory actions on stablecoins, central bank statements on crypto settlement, and measurable shifts in NGN vs stablecoin usage.
• —Persian Gulf: changes in Maersk and peers’ surcharge levels, war-risk premium adjustments, and incident reports affecting Hormuz routing.
• —Armenia: updates to export restriction scope, gas procurement terms, and any alternative supply contracts that change the pricing differential.
• —South Caucasus: further data on Azerbaijan–Russia trade turnover and any new corridor or payment-channel arrangements.
