The Reserve Bank of New Zealand published a Bulletin article alongside a speech by Karen Silk, assistant governor for money, assessing the growing role of the repo market in liquidity management, monetary policy transmission and financial stability. The New Zealand dollar market has expanded alongside government bond issuance and increased activity by offshore nonbank financial institutions. It generally functions well, but legal, operational and structural constraints limit market depth, pricing competition and transparency. Estimated monthly turnover in government bond repo reached around NZD 200 billion in July 2026, while the stock held on registered banks’ balance sheets peaked at around NZD 30 billion in March. Since April 2026, the Reserve Bank has placed weekly full allotment repo operations at the center of its liquidity framework, offering seven-day and 28-day funding at the official cash rate plus 10 basis points. Weekly volumes have averaged about NZD 4.3 billion and peaked above NZD 9.5 billion, while overnight interbank repo pricing appears to have become more stable despite occasional liquidity constraints between operations and around large settlement flows. Silk called on market participants to expand counterparty networks, establish more Global Master Repurchase Agreements and improve price transparency. The Reserve Bank also identified incomplete market data as a monitoring gap and plans to explore improved collection through NZClear. Central clearing or triparty services could reduce some constraints, although market participants questioned whether the market currently has sufficient scale to support central clearing.
