Why Chinese banks are dropping two-year fixed deposits — a lesson in duration and rate expectations
Several Chinese commercial banks have begun removing two-year fixed-term deposit products from their offerings. This follows a broader trend of declining deposit rates and signals something important about how banks manage their balance sheets in a low-interest-rate environment.
When a bank offers a fixed-term deposit, it promises to pay a set interest rate for a set period. The bank then uses those deposits to fund loans. If loan rates are falling and deposit rates remain locked at a higher level, the bank's net interest margin—the difference between what it earns on loans and what it pays on deposits—shrinks. Removing longer-duration deposits is one way to manage that squeeze.
The knowledge lesson: duration matters
The concept at work here is duration—the sensitivity of a financial product's value to interest-rate changes. A two-year deposit locks in a rate for the bank as well as the saver. If the bank expects rates to fall further, it does not want to be locked into paying today's higher rate for two more years.
Three takeaways for savers:
- Product availability signals rate expectations: When banks stop offering longer-term deposits, they are effectively saying they expect rates to stay low or fall further.
- Duration risk works both ways: Savers who want to lock in a rate before it falls further may need to act quickly when products are available. But locking in also means giving up flexibility if rates rise later.
- The broader low-rate environment: Deposit-rate declines are part of a wider shift. Central bank policy-rate cuts, slowing loan demand and efforts to reduce financing costs for businesses all push deposit rates down.
For ordinary households, the practical implication is that the era of parking savings in a fixed deposit and earning a comfortable return is narrowing. Understanding duration and rate expectations helps make more informed choices about when to lock in and when to stay flexible.
