Stay in Your Lane: Peters to Breman

Foreign Minister Winston Peters has publicly urged Reserve Bank of New Zealand (RBNZ) Governor Anna Breman to focus on domestic monetary policy and avoid involvement in U.S. political matters. The comments came after Breman signed a letter of support for Federal Reserve Chair Jerome Powell, who has recently faced subpoenas from the U.S. Justice Department.
In a social media post, Peters emphasised that the RBNZ has no role in U.S. domestic politics. “The Reserve Bank of New Zealand is statutorily independent of Central Government on matters of monetary policy. However, the RBNZ has no role, nor should it involve itself, in U.S. domestic politics,” he wrote. Peters added that the Ministry of Foreign Affairs and Trade (MFAT) would have advised Breman to focus on domestic responsibilities had she sought guidance—which she did not.
Breman is among 14 international central bankers who signed a letter backing Powell’s independence. The statement praised Powell’s integrity and his commitment to serving the American public rather than political interests. The letter reads in part:
“We stand in full solidarity with the Federal Reserve System and its Chair Jerome H. Powell. The independence of central banks is a cornerstone of price, financial and economic stability in the interest of the citizens that we serve… Chair Powell has served with integrity, focused on his mandate and an unwavering commitment to the public interest.”
The letter, published on Wednesday NZT, highlighted the critical importance of maintaining central bank independence, noting that such autonomy is essential for economic and financial stability globally. Other signatories include central bank chairs from Europe, the U.K., Sweden, Denmark, Switzerland, Norway, Australia, Canada, South Korea, Brazil, South Africa, as well as senior figures at the Bank for International Settlements.
The letter comes amid a tense situation in the United States. Jerome Powell has faced subpoenas from the Justice Department related to testimony last June about a multi-year project to renovate the Federal Reserve’s office buildings. The subpoenas follow repeated public pressure from former President Donald Trump, who had urged the Federal Reserve to lower cash rates.
Powell has described the prosecution as retaliation for prioritising the public interest over political preferences. In a brief statement, he said:
“I have served at the Federal Reserve under four administrations, Republicans and Democrats alike. In every case, I have carried out my duties without political fear or favour, focused solely on our mandate of price stability and maximum employment.”
The Reserve Bank of New Zealand confirmed Breman’s involvement, noting that she and the RBNZ strongly support the principle of central bank independence. A spokesperson said the statement was discussed during the BIS Global Economy Meeting, which Breman attended from 1-3am on 14 January. They emphasised that Breman’s signature represents her personal support as well as the stance of the statutorily independent RBNZ.
The RBNZ’s statement reinforced that central bank independence underpins price stability, financial integrity, and broader economic stability. Breman’s participation in the statement reflects her commitment to these principles rather than a position on U.S. domestic politics, the spokesperson said.
While Peters openly criticised Breman’s involvement, Finance Minister Nicola Willis declined to comment on the matter. Peters’ remarks highlight an ongoing tension between the RBNZ’s international engagement and the expectation that its focus remain on New Zealand’s domestic monetary policy.
The incident underscores the delicate balance central bank leaders face in an increasingly globalised financial system. While international cooperation and solidarity on central bank independence are crucial, domestic officials are keen to avoid entanglement in foreign political disputes.
The support letter for Powell may see more international signatories in the coming weeks, reinforcing global recognition of the importance of central bank independence. Meanwhile, the debate in New Zealand continues over the extent to which the Governor of a domestic monetary authority should publicly engage with international political matters, even indirectly.
Peters’ call for Breman to “stay in her New Zealand lane” serves as a reminder that, for now, domestic policy priorities remain the expected focus of the RBNZ, even as global central bankers navigate challenges beyond their borders. -TIN Bureau
