What are interest rate?
Interest rates are the percentage rate calculated based on the principal amount that an individual or organization borrows or invests. It is typically applied to measure the cost of borrowing or the value of investment.
For borrowing, interest rates are the amount of money that borrowers must pay in addition to the principal amount they borrowed. These interest rates can be applied in various ways, such as fixed interest rates (unchanged over a fixed period) or variable interest rates (which may change according to the market or different conditions).
For example, suppose you want to borrow $10,000 from a bank to buy a car. The bank proposes a loan with a fixed interest rate of 5% per year for 5 years. So the total amount you have to repay after 5 years is $12,500.
Investment interest rates: For investment purposes, interest rates are the profit that investors receive from investing their money. Investment interest rates can be returned in various forms, including interest from banks, dividends from stocks, or profits from other investments.
Interest rates can be calculated and applied in various ways depending on the specific type of borrowing or investment, as well as market conditions and legal regulations. Interest rates have a significant impact on the borrowing or investment decisions of individuals and businesses.
Suppose you invest $20,000 in an investment fund with variable interest rates. This investment fund guarantees annual profits, and the interest rates vary based on the performance of the financial market. After one year, the investment fund has achieved a profit of 8%, meaning the investment interest rate is 8%. So after one year, the profit you receive from the investment is $1,600.
Why adjust interest rate?
-
Market stability
Stable interest rates make it easier to predict business and investment environments.
When the economy is growing too strongly and there is a risk of issues such as asset bubbles, central banks may adjust interest rates to reduce economic growth and rebalance the market.
-
Control inflation/deflation
Interest rates are used as a tool to control inflation/deflation and promote economic growth.
-
Adjust exchange rates
Interest rates can also affect exchange rates. When interest rates rise, the currency of a country may become more attractive to investors, leading to an increase in the value of that currency. Conversely, when interest rates decrease, the currency may depreciate.
Factors affecting interest rate
Interest rates are the price of money. Similar to any other commodity or service, interest rates are determined by supply and demand. When borrowing demand increases (due to high investment or consumption demand), interest rates tend to rise. Conversely, when demand decreases (due to economic downturn or reduced borrowing demand), interest rates may decrease.
Fluctuations in financial markets, including stock markets and currency markets, can affect interest rates. Investors and central banks react to these fluctuations by adjusting interest rates to protect and create incentives for the market.
-
Economic situation
In a strong economy, borrowing demand increases due to high demand from businesses and individuals. This can lead to an increase in interest rates. Meanwhile, in an economic downturn, borrowing demand decreases, and interest rates may be reduced to stimulate economic growth.
Central banks often have the responsibility to adjust the basic interest rates to regulate financial activities and economic growth. Increasing interest rates may reduce consumer and investment spending, helping to control inflation. Conversely, reducing interest rates can stimulate spending and investment, promoting economic growth.
1.1. Inflation rate
Inflation reduces the value of money and increases costs for businesses and consumers. To control inflation, central banks may increase interest rates to make borrowing more expensive, reduce spending and investment, thereby reducing inflationary pressures.
1.2. Deflation rate
In deflation, prices may decrease, increasing the purchasing power of consumers and businesses. However, if deflation is severe, central banks may lower interest rates to stimulate borrowing and investment, thereby promoting economic growth.
-
Budget deficit ratio
If a country has a large budget deficit ratio, they need to attract investors to buy their government bonds. To do this, they may increase interest rates to make their bonds more attractive.
-
Unemployment rate
High unemployment rates can reduce inflationary pressure, and increasing interest rates can help create new jobs by stimulating investment and economic activity.
-
Global financial market conditions
If there are signs of recession or instability in the global economy, central banks such as the Federal Reserve may raise interest rates to protect the currency and control inflationary pressures and market stability.
In stable and developing economies, people’s savings rates tend to increase. People tend to save or invest. This leads to an increase in the money supply in the financial system.
-
Expected inflation
When inflation is expected to rise, investors tend to shift investments from cash or high-risk assets to safer assets such as gold, strong currencies, or government bonds with high interest rates. This increases the demand for safe assets and reduces the demand for borrowing from the financial system.
When there is a shift from capital into safe assets, the capital supply in the financial system decreases. This creates pressure to increase interest rates due to limited capital supply, making borrowing more expensive.
To deal with this situation, central banks may increase the basic interest rates to reduce pressure on the financial market and control inflation. By increasing interest rates, they can create a more attractive point for depositing money into the financial system and reduce the conversion to safe assets.
Significance of interest rate
In the challenging context of the global financial market and economy, interest rates are not only a numerical indicator but also an important tool to adjust and control economic activities.
In this article, we have discussed the factors affecting interest rates, including economic conditions, inflation, global financial markets, and central bank monetary policies. These factors create a complex network of interactions and affect the volatility of interest rates, which can have profound effects on the economy and financial markets.
This emphasizes the important role of effectively managing interest rates in maintaining stability and sustainable development of the economy. At the same time, close cooperation among stakeholders, including governments, central banks, and financial institutions, is needed to ensure that interest rate adjustments are implemented effectively and beneficial to the entire economy.
