Enflasyon, Faiz ve Paranızı Nasıl Etkiler?

In 1970, the average UK house cost £4,975. A pint of milk was 5p. A loaf of bread was 9p. Today, the average house costs over £280,000, milk is around £1.50, and bread costs £1.40. This isn't because houses and bread got better — it's because the pound got weaker. That's inflation. Inflation means the general increase in prices over time — or equivalently, the decrease in what your money can buy. A moderate amount (the Bank of England targets 2% per year) is considered healthy. It encourages spending and investment: if prices will be higher tomorrow, you have a reason to buy today. But high inflation is devastating. In 1923, Germany experienced hyperinflation so severe that workers were paid twice a day and rushed to spend their wages before prices rose again. A loaf of bread that cost 250 marks in January cost 200 billion marks by November. People wallpapered their homes with banknotes because the paper was worth more as decoration than as currency. The UK experienced its own inflation crisis in 2022-2023, when CPI hit 11.1% — the highest in 41 years. Energy bills doubled. Food prices surged 19%. The cause? A combination of post-COVID supply chain disruption, Russia's invasion of Ukraine (affecting gas and wheat prices), and years of quantitative easing (printing money) that injected over £895 billion into the economy. The tool governments use to fight inflation is interest rates — and understanding how they work is one of the most valuable financial skills you can have.

The Bank of England sets the 'base rate' — the interest rate at which it lends to commercial banks. This ripples through the entire economy: **When rates go UP** (fighting inflation): - Borrowing becomes more expensive → people take fewer loans, buy fewer houses, spend less - Saving becomes more rewarding → people save more, spend less - Businesses invest less → slower growth, potentially fewer jobs - Demand falls → prices stabilise or fall - Your mortgage payments increase **When rates go DOWN** (stimulating growth): - Borrowing becomes cheaper → more loans, more house purchases, more spending - Saving earns less → people spend rather than save - Businesses invest more → faster growth, more jobs - Demand rises → prices may increase - Your mortgage payments decrease **The key numbers to understand:** - **Nominal interest rate**: The rate the bank advertises (e.g., 4.5% on savings) - **Real interest rate**: Nominal rate minus inflation. If savings pay 4.5% but inflation is 6%, your real return is -1.5%. Your money is shrinking. - **APR**: Annual Percentage Rate — what you actually pay on loans, including fees - **Compound interest**: Interest on interest. £10,000 at 5% compound interest becomes £16,289 after 10 years. Albert Einstein (apocryphally) called it 'the eighth wonder of the world.' **The rule of 72**: Divide 72 by the interest rate to estimate how long it takes money to double. At 6% interest, your money doubles in roughly 12 years.
