RBNZ FAQs

The Reserve Bank of New Zealand (RBNZ) is the country’s central bank. Its economic objectives are achieving and maintaining price stability – achieved when inflation, measured by the Consumer Price Index (CPI), falls within the band of between 1% and 3% – and supporting maximum sustainable employment.

The Reserve Bank of New Zealand’s (RBNZ) Monetary Policy Committee (MPC) decides the appropriate level of the Official Cash Rate (OCR) according to its objectives. When inflation is above target, the bank will attempt to tame it by raising its key OCR, making it more expensive for households and businesses to borrow money and thus cooling the economy. Higher interest rates are generally positive for the New Zealand Dollar (NZD) as they lead to higher yields, making the country a more attractive place for investors. On the contrary, lower interest rates tend to weaken NZD.

Employment is important for the Reserve Bank of New Zealand (RBNZ) because a tight labor market can fuel inflation. The RBNZ’s goal of “maximum sustainable employment” is defined as the highest use of labor resources that can be sustained over time without creating an acceleration in inflation. “When employment is at its maximum sustainable level, there will be low and stable inflation. However, if employment is above the maximum sustainable level for too long, it will eventually cause prices to rise more and more quickly, requiring the MPC to raise interest rates to keep inflation under control,” the bank says.

In extreme situations, the Reserve Bank of New Zealand (RBNZ) can enact a monetary policy tool called Quantitative Easing. QE is the process by which the RBNZ prints local currency and uses it to buy assets – usually government or corporate bonds – from banks and other financial institutions with the aim to increase the domestic money supply and spur economic activity. QE usually results in a weaker New Zealand Dollar (NZD). QE is a last resort when simply lowering interest rates is unlikely to achieve the objectives of the central bank. The RBNZ used it during the Covid-19 pandemic.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

On November 3, the Balancer V2 protocol and its fork projects were attacked on multiple chains, resulting in a serious loss of more than $120 million. BlockSec issued an early warning at the first opportunity [1] and gave a preliminary analysis conclusion [2]. This was a highly complex attack. Our preliminary analysis showed that the root cause was that the attacker manipulated the invariant, thereby distorting the calculation of the price of BPT (Balancer Pool Token) -- that is, the LP token of Balancer Pool -- so that it could profit in a stable pool through a batchSwap operation. Background Information 1. Scaling and Rounding To standardize the decimal places of different tokens, the Balancer contract will: upscale: Upscales the balance and amount to a uniform internal precision before performing the calculation; downscale: Reduces the result to its original precision and performs directional rounding (e.g., inputs are usually rounded up to ensure the pool is not under-filled; output paths are often truncated downwards). Conclusion: Within the same transaction, the asymmetrical rounding direction used in different stages can lead to a systematic slight deviation when executed repeatedly in very small steps. 2. Prices of D and BPT The Balancer V2 protocol’s Composable Stable Pool[3] and the fork protocol were affected by this attack. Stable Pool is used for assets that are expected to maintain a close 1:1 exchange ratio (or be exchanged at a known exchange rate), allowing large exchanges without causing significant price shocks, thereby greatly improving the efficiency of capital utilization between similar or related assets. The pool uses the Stable Math (a Curve-based StableSwap model), where the invariant D represents the pool's "virtual total value". The approximate price of BPT (Pool's LP Token) is: The formula above shows that if D is made smaller on paper (even if no funds are actually withdrawn), the price of BPT will be cheaper. BTP represents the pool share and is used to calculate how many pool reserves can be obtained when withdrawing liquidity. Therefore, if an attacker can obtain more BPT, they can profit when withdrawing liquidity. Attack Analysis Taking an attack transaction on Arbitrum as an example, the batchSwap operation can be divided into three stages: Phase 1: The attacker redeems BPT for the underlying asset to precisely adjust the balance of one of the tokens (cbETH) to a critical point (amount = 9) for rounding. This step sets the stage for the precision loss in the next phase. Phase Two: The attacker uses a carefully crafted quantity (= 8) to swap between another underlying asset (wstETH) and cbETH. Due to rounding down when scaling the token quantity, the calculated Δx is slightly smaller (from 8.918 to 8), causing Δy to be underestimated and the invariant D (derived from Curve's StableSwap model) to be smaller. Since BPT price = D / totalSupply, the BPT price is artificially suppressed. Phase 3: The attackers reverse-swap the underlying assets back to BPT, restoring the balance within the pool while profiting from the depressed price of BPT—acquiring more BPT tokens. Finally, the attacker used another profitable transaction to withdraw liquidity, thereby using the extra BPT to acquire other underlying assets (cbETH and wstETH) in the Pool and thus profit.
