## Key takeaways

- SBV FX Swap operations supply short-term VND liquidity without altering net foreign exchange reserves.
- Swap point forward pricing aligns with interbank VND - USD interest rate differentials.
- Mitigates year-end funding cost spikes across commercial banks.

The State Bank of Vietnam (SBV) utilizes foreign currency swaps (FX Swaps) as a calibrated monetary tool to inject or absorb short-term VND liquidity without disturbing the structural trajectory of net foreign exchange reserves.

### Operational Transmission Mechanism

During seasonal payment peaks, commercial banks can deliver USD spot to the central bank in exchange for immediate domestic currency funding, alongside a binding forward commitment to reverse the transaction.

```flow
[
  "1. Commercial banks deliver spot USD to the central bank",
  "2. SBV credits counterparty accounts with VND liquidity",
  "3. Interbank overnight borrowing rates stabilize immediately",
  "4. At maturity: banks repurchase USD and return VND funds"
]
```

### Covered Interest Parity and Swap Pricing

The forward swap premium is governed by the covered interest parity framework:

$$\text{Swap Points} = \text{Spot Rate} \times \left( \frac{\text{VND Rate} - \text{USD Rate}}{1 + \text{USD Rate} \times \frac{\text{Days}}{360}} \right) \times \frac{\text{Days}}{360}$$

As the VND-USD policy rate spread narrows, swap funding costs moderate, facilitating efficient treasury asset-liability balancing.

> Chart: 1-Month VND - USD Interbank Yield Differential Trend. %. Jun-26: −1,20; Jul-26: −0,80; Aug-26: −0,40; Sep-26: 0,10; Oct-26: 0,30; Nov-26: 0,45.

### Comparative Monetary Instruments

| Instrument | FX Reserve Impact | Operational Horizon | Commitment Structure |
| :--- | :--- | :--- | :--- |
| **Outright USD Purchase** | Expands permanent reserves | Indefinite | Unconditional purchase |
| **FX Swap (Buy/Sell)** | Reserve neutral at maturity | 14 days – 90 days | Automated reversal leg |
| **Open Market Ops (OMO)** | Zero foreign currency involvement | 7 days – 28 days | Secured by sovereign debt |

### Strategic Capital Market Implications

1. **Deposit Rate Insulation:** Relieves pressure on retail deposit competition across joint-stock lenders by addressing systemic interbank friction directly.
2. **Speculative Flow Containment:** Forward commitments anchor foreign exchange expectations firmly within the central bank's guided currency band.

## Frequently asked questions

### How does an FX Swap differ from an outright foreign exchange purchase?

An FX swap combines simultaneous spot and forward legs with two different value dates, leaving net reserves neutral at maturity.

### What variables drive the swap point pricing in Vietnam?

Swap points reflect the interest rate differential between VND and USD in the interbank market across matching maturities.
