Gini · Learn investing · 2026-10-27 · https://ginity.vn/en/blog/reading-macro-news-cpi-rates-fx _Lead analyst: Đào Ngọc Bảo Linh · Finance and securities specialist · Ho Chi Minh City · 0932 439 639_ ## Key takeaways - Vietnam average CPI in the first 9 months of 2026 rose 4.52% year on year according to the NSO release on 03/10/2026. - Core inflation averaged a 4.26% increase year on year over the first 9 months of 2026 after removing volatile items. - The State Bank of Vietnam kept the refinancing rate at 4.5% and the rediscount rate at 3.0%, unchanged since the State Bank's decision of 16 June 2023. - The USD/VND spot exchange rate band is maintained at ±5% around the daily central rate under Decision 1747/QD-NHNN. Macro economic statistics determine the baseline cost of capital, consumer purchasing power, and cash flow expectations across financial markets. Investors who read primary official statistical releases avoid reacting to secondary media commentary. This guide outlines how to interpret three essential economic indicators in Vietnam: the consumer price index from the National Statistics Office, the policy rate framework of the State Bank of Vietnam, and the daily central exchange rate band for USD/VND. ## Three Economic Variables Shaping Capital Costs Financial markets value assets by discounting future cash flows. Three macro economic variables directly alter corporate valuation parameters: 1. The Consumer Price Index (CPI) tracks price changes across a representative consumer basket. Rapid inflation erodes household purchasing power and inflates industrial input costs, shrinking operating margins. 2. Policy interest rates set by the central bank establish the baseline for bank lending rates, shaping corporate debt expense and equity discount rates. 3. The foreign exchange rate (USD/VND) determines the domestic value of foreign currency debt, affects trade cash flows, and influences cross-border investment capital. Understanding how these three metrics interact enables market participants to assess corporate resilience through verified statistical releases. ## Understanding the Consumer Price Index Framework The National Statistics Office of Vietnam (NSO), formerly the General Statistics Office (GSO), is the sole official body responsible for calculating and publishing CPI figures at the end of each month or early in the following month. When reviewing monthly NSO price reports, analysts examine three measurement perspectives: - Month-on-month change: Captures short-term price shifts caused by seasonal consumption patterns or regulated utility tariff adjustments compared with the preceding month. - Year-on-year change (YoY): Compares price levels in the reporting month with the identical month of the previous year, stripping out twelve-month seasonal cycles. - Cumulative average increase: Measures the average CPI across elapsed months of the year compared with the equivalent period of the previous year. This cumulative average serves as the official metric evaluated by the National Assembly for annual inflation targets. In addition to headline CPI, the NSO releases core inflation figures. Core inflation excludes fresh food, energy products subject to state price regulation, and public healthcare and education tariffs to isolate underlying monetary price pressures. According to the official statistical release by the [National Statistics Office of Vietnam (NSO)](https://www.nso.gov.vn/en/data-and-statistics/2026/10/consumer-price-index-gold-price-index-and-us-dollar-price-index-in-september-2026-q3-2026-and-the-nine-months-of-2026/) on 03/10/2026, the consumer price index in September 2026 rose 0.62% compared with August 2026, 4.20% compared with December 2025, and 5.08% year on year compared with September 2025. Average CPI in the third quarter of 2026 increased 4.80% compared with the third quarter of 2025. Over the first 9 months of 2026, average CPI increased 4.52% year on year, while core inflation over the first 9 months of 2026 rose 4.26%. According to reporting published by [VietnamPlus](https://en.vietnamplus.vn/vietnams-cpi-rises-452-in-first-nine-months-of-2026-post353045.vnp) on 03/10/2026, higher domestic fuel prices were the main driver of the September 2026 CPI change, with tuition fee increases also contributing. ## Central Bank Policy Rates and Money Market Liquidity The State Bank of Vietnam (SBV) manages domestic monetary policy through an administrative interest rate corridor consisting of several operational facilities: - Refinancing rate: The benchmark rate applied when the central bank extends liquidity loans to commercial banks. - Rediscount rate: The rate charged when commercial credit institutions discount eligible short-term negotiable instruments at the SBV. - Overnight lending rate: The ceiling rate for settling interbank electronic payment deficiencies at the end of each business day. - Open Market Operations (OMO): The channel used to issue central bank bills to absorb surplus liquidity, or execute pledged collateral lending to inject short-term funds. According to [Decision 1123/QD-NHNN](https://en.baochinhphu.vn/central-bank-cuts-regulatory-interest-rate-111230616172123401.htm), the State Bank of Vietnam set the refinancing rate at 4.5% and the rediscount rate at 3.0%, unchanged since the State Bank's decision of 16 June 2023. According to information from the press conference on 07/10/2026 published by [Government News](https://baochinhphu.vn/nhnn-toc-do-tang-lai-suat-dang-cham-lai-102261007182510571.htm), the State Bank of Vietnam confirmed that it maintained key policy interest rates unchanged in 2026 to support economic growth. The central bank reported that average interest rates on newly issued bank deposits stood at 6.38% as of 20/09/2026, up 1.15% from the end of 2025. System credit expanded 16.69% year on year to reach 20,750 trillion VND by the end of September 2026. The interbank market (Market 2) operates where commercial banks trade reserve balances. The overnight interbank rate (VNIBOR) fluctuates daily, reflecting immediate liquidity distribution across the banking system. ## Central Exchange Rate and the USD/VND Trading Band Vietnam manages the exchange rate via a daily central rate mechanism announced each business morning by the State Bank of Vietnam based on interbank weighted rates, a basket of primary partner currencies, and macro economic balance targets. Commercial banks execute foreign exchange spot transactions strictly within an established regulatory band around this rate. According to Decision 1747/QD-NHNN dated 17/10/2022 documented on the [Online Portal of the Government](https://en.baochinhphu.vn/state-bank-of-viet-nam-expands-exchange-rate-trading-band-111221019090443862.htm), the State Bank of Vietnam set the spot trading band for USD/VND at ±5% around the daily central exchange rate. According to regulatory rules in Decision 1747/QD-NHNN from 2022, the upper transaction ceiling equals the central rate multiplied by 1 plus 5%, while the floor equals the central rate multiplied by 1 minus 5%. Policy directives reported by [Government News](https://en.baochinhphu.vn/pm-orders-sbv-to-monitor-exchange-rate-flexibly-in-line-with-market-developments-111260814092550224.htm) on 14/08/2026 instructed monetary authorities to manage the exchange rate flexibly in line with market developments and intervene to stabilize the foreign exchange market in 2026. ## Summary Matrix of Vietnamese Economic Indicators The table below outlines key Vietnamese economic metrics, reporting intervals, and primary publication authorities: | Economic Indicator | Issuing Authority | Frequency | Nine Months of 2026 Level | Market Analytical Role | | :--- | :--- | :--- | :--- | :--- | | Headline CPI (average) | National Statistics Office (NSO) | Monthly | 4.52% YoY increase | Official inflation benchmark for annual policy targets | | Core Inflation (average) | National Statistics Office (NSO) | Monthly | 4.26% YoY increase | Strips volatile food and fuel to isolate monetary pressures | | SBV Refinancing Rate | State Bank of Vietnam (SBV) | Discretionary | 4.5% annual rate | Benchmark policy rate for commercial bank credit costs | | New Deposit Rate (average) | State Bank of Vietnam (SBV) | Periodic | 6.38% as of 20/09/2026 | Effective cost of deposit funding for banking institutions | | USD/VND Spot Band | State Bank of Vietnam (SBV) | Standing framework | ±5% around central rate | Legal operational boundary for commercial spot FX transactions | Source: Compiled by Ginity from official statistical releases by NSO, SBV, and the Government Portal in 2026. ## Worked Example: Evaluating Macro Releases for 9M 2026 To understand how macro figures apply to financial analysis, consider an industrial components manufacturer listed on the stock exchange with local currency debt and raw material purchases invoiced in US dollars. An analyst applies four sequential evaluation steps: Step one: Evaluate cost inflation pressures. According to the NSO report for the first 9 months of 2026, average headline CPI rose 4.52% year on year while core inflation increased 4.26% year on year. The spread between headline and core inflation in the first 9 months of 2026 was 0.26 percentage points (Ginity's calculation: 4.52% minus 4.26% equals 0.26%). Step two: Calculate the real interest rate burden. The relationship between nominal interest rates, inflation, and real yields is expressed through the display formula: $$\text{Real interest rate} \approx \text{Nominal interest rate} - \text{Inflation rate}$$ According to SBV data from 07/10/2026, the average new deposit rate stood at 6.38% as of 20/09/2026. Across the first 9 months of 2026, the average CPI inflation rate published by NSO on 03/10/2026 reached 4.52%. Applying the formula to these sourced 2026 figures: $$\text{Real deposit rate} \approx 6.38\% - 4.52\% = 1.86\%$$ According to Ginity's calculation, the resulting positive real rate of 1.86% in 2026 confirms that domestic currency deposits maintain real purchasing power. Step three: Determine commercial FX operational boundaries. According to the regulatory framework in Decision 1747/QD-NHNN issued in 2022, suppose, for example, a hypothetical central exchange rate of 20,000 VND/USD in 2022 to illustrate the calculation. Applying the ±5% regulatory band under Decision 1747/QD-NHNN in 2022 yields: the trading ceiling equals 20,000 multiplied by 1.05 to reach 21,000 VND/USD, and the trading floor equals 20,000 multiplied by 0.95 to reach 19,000 VND/USD (Ginity's calculation). In this hypothetical example for 2022, suppose quoted rates reach 21,000 VND/USD, prices trade at the upper ceiling of the regulatory band. Step four: Synthesize corporate valuation impact. According to the combined figures, maintaining an average CPI of 4.52% alongside an average deposit rate of 6.38% in 2026 implies that firms with high operational efficiency and low floating-rate leverage sustain operating margins more effectively. ## Systematic Verification Protocol for Market Observers To avoid reliance on unverified commentary, market participants should follow four verification practices: First, retrieve the original statistical press releases and statistical data tables directly from the official NSO portal (nso.gov.vn) rather than reading secondary summaries. Second, verify whether reported figures represent month-on-month changes against the preceding month, year-on-year comparisons (YoY), or cumulative multi-month averages. Third, confirm administrative monetary policy updates on sbv.gov.vn or the government portal (chinhphu.vn) to verify specific decision numbers and effective dates. Fourth, track cumulative quarterly time series to distinguish transient price spikes from sustained monetary shifts, supporting disciplined capital allocation decisions. ## Sources - Online Portal of the Government: [Adjustment of regulatory interest rates under Decision 1123/QD-NHNN](https://en.baochinhphu.vn/central-bank-cuts-regulatory-interest-rate-111230616172123401.htm) (16/06/2023) - National Statistics Office of Vietnam (NSO): [Consumer price index, gold price index and US dollar price index in September 2026, Q3/2026 and nine months of 2026](https://www.nso.gov.vn/en/data-and-statistics/2026/10/consumer-price-index-gold-price-index-and-us-dollar-price-index-in-september-2026-q3-2026-and-the-nine-months-of-2026/) (03/10/2026) - Government News: [SBV: Interest rate increases are slowing down](https://baochinhphu.vn/nhnn-toc-do-tang-lai-suat-dang-cham-lai-102261007182510571.htm) (07/10/2026) - Government News: [PM orders SBV to monitor exchange rate flexibly in line with market developments](https://en.baochinhphu.vn/pm-orders-sbv-to-monitor-exchange-rate-flexibly-in-line-with-market-developments-111260814092550224.htm) (14/08/2026) - Online Portal of the Government: [Adjustment of USD/VND spot exchange rate band to 5% under Decision 1747/QD-NHNN](https://en.baochinhphu.vn/state-bank-of-viet-nam-expands-exchange-rate-trading-band-111221019090443862.htm) (17/10/2022) - VietnamPlus: [Vietnam's CPI rises 4.52% in first nine months of 2026](https://en.vietnamplus.vn/vietnams-cpi-rises-452-in-first-nine-months-of-2026-post353045.vnp) (03/10/2026) --- _Source: Ginity (ginity.vn).
