Y
Yemeni Rial (YER)
The Yemeni rial, identified by the code YER, is the official currency of Yemen. In ordinary circumstances, that would lead to one recognised market rate. Yemen’s divided financial system makes the picture much more complicated.
Rival authorities operate from Sana’a and Aden, different banknotes circulate across regions, and the same face value can trade at sharply different exchange rates. A payment of 100,000 rials may therefore carry a different real value depending on where it is received and which notes are accepted.
For businesses and market observers, a published YER rate needs context. Geography and political control are part of the currency story here.
Yi Gang
Yi Gang is a Chinese economist who served as governor of the People’s Bank of China from 2018 to 2023. Before taking the top role, he spent years in senior monetary-policy and foreign-exchange positions, including as a deputy governor and head of the State Administration of Foreign Exchange.
Markets followed his speeches for clues about interest rates, liquidity, financial reform, and the yuan. A carefully worded comment on currency stability could shift expectations even before any formal policy announcement.
His name still appears regularly in reports covering that period. Reading those reports accurately means recognising him as a former governor and understanding the policy setting in which he was speaking.
Yield
Yield is the income an investment generates, usually shown as a percentage. In simple terms, it tells you how much money you receive from holding an asset, without focusing on whether the asset’s price goes up or down.
Yield is commonly used with bonds, dividend-paying stocks, funds, and sometimes currencies. For bonds, it usually comes from interest payments. For stocks, it often comes from dividends. This makes yield especially useful for investors who want regular income from their portfolio.
Yield is different from total return. Return includes income plus any gain or loss in the asset’s price. Yield focuses mainly on the income side.
Example:
If you buy a stock for $100 and it pays $5 in dividends over one year, the dividend yield is 5%. This means you earned $5 in income for every $100 invested.
A higher yield can look attractive, but it is not always safer. Sometimes, a very high yield may signal higher risk, such as a weak company or a bond issuer that must offer more income to attract investors.
Yield Chasing
Yield chasing happens when an investor moves toward higher-returning assets without giving the added risk equal attention. It often becomes more visible when safer investments offer modest income and the larger percentage starts to dominate the decision.
A government bond may yield 4%, while a lower-rated corporate bond offers 9%. The additional return may reflect a greater chance of default, weaker liquidity, longer maturity, or larger price swings.
Yield chasing can appear in bonds, dividend shares, private credit, and crypto. Comparing the credit quality, liquidity, and structure behind the yield gives a more useful picture than comparing the percentages alone.
Yield Curve
A yield curve places the yields of similar bonds with different maturity dates on one line. It gives traders and investors a quick view of how the market is pricing time.
A normal curve slopes upward because longer-term bonds usually offer higher yields. A flat curve shows little difference between maturities. An inverted curve appears when short-term yields rise above longer-term yields.
If a two-year government bond yields 5% while a ten-year bond yields 4%, the curve is inverted. That shape may reflect expectations of slower growth or lower interest rates later. Traders watch not only the shape of the curve, but also how quickly it is steepening, flattening, or shifting.
Yield Curve Control (YCC)
Yield curve control, or YCC, is a central-bank policy aimed at keeping a selected government-bond yield near a target. The bank buys or sells bonds as needed to influence that part of the curve.
A central bank targeting a ten-year yield of 0.5% may buy bonds if heavy selling pushes it to 0.7%. The purchases lift bond prices and place downward pressure on the yield.
The distinction from quantitative easing is useful. QE usually begins with an amount of bonds to purchase. YCC begins with the yield the bank wants to maintain. The policy can steady borrowing costs, although it also changes how freely the bond market sets prices.
