- Norway's $2.1T sovereign wealth fund NBIM terminated Turkish firm Istanbul Portfoy after its managing partner faced Turkish regulators for market manipulation.

- The firm managed $600M of NBIM's Turkish assets but failed to disclose regulatory findings, prompting a 18.5M lira ($423K) fine for misleading share trades.

- NBIM emphasized zero tolerance for non-compliance, now seeking new Turkish managers amid global ethical investment reviews led by Finance Minister Stoltenberg.

- The move highlights risks of relying on external managers in complex regulatory environments, aligning with NBIM's strict transparency and governance priorities.

Norges Bank Investment Management, the $2.1 trillion sovereign wealth fund of Norway, has terminated its relationship with Istanbul Portfoy Yonetimi AS, a Turkish investment firm, after regulatory action against one of its managing partners for improper trading activities.

The firm had managed around $600 million on the fund's behalf and was overseeing part of NBIM's Turkish investments, which totaled 17.4 billion kroner ($1.8 billion). The decision to cut ties was made in November, soon after Turkish regulators imposed a fine on the firm's managing partner for market manipulation.

The Norwegian fund's move underscores the significance of compliance and transparency in its investment strategy. The firm was faulted for failing to proactively disclose the regulatory findings.

Why the Termination Occurred

Turkish regulators issued a fine of 18.5 million liras ($423,000) to Istanbul Portfoy managing partner Tufan Deriner for creating a misleading impression about the supply, demand, and pricing of shares in two cement companies. The Capital Markets Board of Turkey cited "market manipulation" in its regulatory bulletin dated Oct. 23.

The trades in question were not related to NBIM's managed funds in Turkey, which were handled by a different portfolio manager at the firm. Despite this, the severity of the regulatory finding prompted the Norwegian fund to end the relationship.

Implications for the Norwegian Fund's Manager Strategy

NBIM uses over 100 external managers globally, relying on them in markets where local knowledge is essential. In its 2024 LinkedIn post, NBIM CEO Nicolai Tangen emphasized the importance of such partnerships for understanding local conditions.

The decision to terminate the Istanbul Portfoy relationship indicates the fund's zero-tolerance approach to regulatory noncompliance. It also highlights the potential risks of relying on external managers in complex regulatory environments.

What Comes Next in the Fund's Local Management Search

The Norwegian fund is currently seeking a new investment manager in Turkey. In December, other Turkish asset-management firms received urgent invitations to meet with NBIM representatives, signaling a potential shift in its local management strategy.

The fund's move reflects broader challenges in managing ethical and regulatory expectations across its global investments. Norway's central bank governor recently highlighted tensions between domestic and international expectations regarding responsible investments.

Norges Bank Investment Management is the world's largest sovereign wealth fund and is known for its strict ethical guidelines. The fund's current review of its ethical investment strategy, initiated by Finance Minister Jens Stoltenberg, could further shape its approach to local investment partners.

In the interim, NBIM is expected to prioritize compliance and transparency in its search for a new Turkish manager, aligning with its ongoing emphasis on ethical governance.
