Inflation FAQs

Inflation measures the rise in the price of a representative basket of goods and services. Headline inflation is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core inflation excludes more volatile elements such as food and fuel which can fluctuate because of geopolitical and seasonal factors. Core inflation is the figure economists focus on and is the level targeted by central banks, which are mandated to keep inflation at a manageable level, usually around 2%.

The Consumer Price Index (CPI) measures the change in prices of a basket of goods and services over a period of time. It is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core CPI is the figure targeted by central banks as it excludes volatile food and fuel inputs. When Core CPI rises above 2% it usually results in higher interest rates and vice versa when it falls below 2%. Since higher interest rates are positive for a currency, higher inflation usually results in a stronger currency. The opposite is true when inflation falls.

Although it may seem counter-intuitive, high inflation in a country pushes up the value of its currency and vice versa for lower inflation. This is because the central bank will normally raise interest rates to combat the higher inflation, which attract more global capital inflows from investors looking for a lucrative place to park their money.

Formerly, Gold was the asset investors turned to in times of high inflation because it preserved its value, and whilst investors will often still buy Gold for its safe-haven properties in times of extreme market turmoil, this is not the case most of the time. This is because when inflation is high, central banks will put up interest rates to combat it. Higher interest rates are negative for Gold because they increase the opportunity-cost of holding Gold vis-a-vis an interest-bearing asset or placing the money in a cash deposit account. On the flipside, lower inflation tends to be positive for Gold as it brings interest rates down, making the bright metal a more viable investment alternative.

USD/JPY retreats from nearly two-year high on hawkish BoJ Minutes

USD/JPY drifts lower during the Asian session on Friday, retreating further from its highest level since July 2024, set the previous day. Minutes from the April BoJ meeting keep further policy normalization firmly on the table amid expectations for a pickup in inflation over the coming months, due to higher energy costs. This offsets Japan's softer National CPI print and lifts the Japanese Yen amid intervention fears, exerting some pressure on the currency pair.

AUD/USD awaits 0.7000 breakdown before the next leg down amid bullish USD

AUD/USD holds above 0.7000 during the Asian session on Friday, though it remains close to the weekly low and seems poised to register modest weekly losses. The US Dollar sits near its highest level since May 2025 as the Fed's hawkish tilt overshadows optimism over the US-Iran peace deal, capping the currency pair. However, the RBA's signal that additional rate hikes were possible if inflation persists lends some support to the Aussie.

Gold refreshes weekly low as Fed's hawkish tilt underpins USD

Gold attracts sellers for the third consecutive day and weakens below $4,200, hitting a fresh weekly low during the Asian session on Friday. Despite the latest optimism over a US-Iran peace deal, the Fed's hawkish tilt helps the US Dollar to preserve its strong weekly gains to the highest level since May 2025. This, in turn, undermines the non-yielding bullion and backs the case for further losses.
