1. Hong Kong
For centuries China/Britain ran a one-sided trade balance: Britain imported tea, silk, and porcelain, paying in silver. To reverse the outflow, Britain’s East India Company pushed Indian opium into China. When the Qing cracked down, confiscating 20,000 chests in Canton, Britain sent gunboats. The First Opium War exposed China’s military weakness. The Treaty of Nanking (1842) ceded Hong Kong Island to Britain “in perpetuity,” opened five treaty ports, and guaranteed British extraterritorial rights. Hong Kong was chosen for its deep harbor and position near Canton — the new base for empire and “free trade.”
The colony quickly became the commercial and naval center of Britain’s China trade. Opium smuggling remained central for decades, financing the purchase of Chinese goods. British merchants built trading houses, docks, and banks — most famously HSBC (1865) — while Chinese workers and traders powered the economy. After the Second Opium War (1856–1860), Britain took Kowloon Peninsula, then in 1898 leased the New Territories for 99 years. By 1900 Hong Kong was the Empire’s key Asia port: low taxes, free trade, British law, and a strategic Royal Navy base.
Hong Kong prospered as a transit and banking hub until Japan’s 1941 invasion. The colony fell within weeks; Japanese occupation lasted until 1945. Post-war, Britain rebuilt the city, and the 1949 Communist victory in China sent millions of refugees — workers, entrepreneurs, and capital — south. They drove an export-led manufacturing boom in textiles, plastics, and electronics. British administration provided rule of law and minimal interference; this combination of stability and capitalism made Hong Kong a rare success in Asia’s Cold War landscape.
As wages rose, factories shifted to mainland China, while Hong Kong evolved into a finance, logistics, and service hub for Asia. The city’s stock exchange, shipping firms, and banks became regional anchors. With the 99-year lease on the New Territories expiring, Britain and China negotiated the 1984 Sino-British Joint Declaration: Hong Kong would return to China in 1997 under “one country, two systems”, keeping its capitalist system and common-law courts for 50 years. The handover on 1 July 1997 ended 156 years of British rule.
Now a Special Administrative Region of China, Hong Kong retained its own currency (the HK dollar), judiciary, and trade autonomy. It became the financial gateway to China, handling capital inflows, listings, and offshore banking.
2. Taiping Rebellion
The Taiping Rebellion (1850-1864) erupted after China’s humiliating defeat in the First Opium War left the Qing Dynasty weakened, corrupt, and facing famine. Hong Xiuquan, a failed scholar claiming to be Jesus’s brother, mobilized millions of desperate Han Chinese peasants against their Manchu rulers with revolutionary ideology. His forces took Nanjing in 1853 and controlled southern China for a decade.
The Manchu court’s banner armies couldn’t stop the rebellion, so they empowered Han regional leaders like Zeng Guofan to raise their own forces. These Han armies crushed the Taipings at the cost of 20-30 million lives, but the Manchu central government never reclaimed military control. Real power shifted to Han provincial commanders, the dynasty gave more concessions to Western powers, and the whole structure collapsed in 1911. The Taiping Rebellion kicked off imperial China’s death spiral.
3. Yield-Curve Trading
A yield-curve trade is a shape bet: you want one maturity to outperform another (e.g., long 10s/short 2s for a steepener) while being indifferent to a parallel move in rates. That neutrality is engineered with DV01, the bond’s “dollars per basis point”—how many dollars its price changes if its yield moves 0.01%. Longer, lower-coupon bonds have larger DV01 because more value sits in distant cash flows. Order of magnitude per $1mm near par: ~$190 for a 2-year, ~$850 for a 10-year, ~$1,800 for a 30-year. To neutralize direction, size the legs so DV01s cancel. Example: long $10mm of 10-year (≈$850/bp → $8.5k per bp) and short about $44.7mm of 2-year (≈$190/bp → $8.5k per bp). A +10 bp parallel shift then loses ≈$85k on the long and gains ≈$85k on the short—flat to level, exposed only to relative 2s-vs-10s moves.
DV01 matching is linear; bonds aren’t. The 10-year is far more convex than the 2-year. In a big rally, the long end rallies more than duration predicts, so a steepener over-earns. In a big sell-off, the 10-year does fall “less than predicted” on a percentage basis, but because its DV01 is large you still take a big dollar loss while the 2-year hardly moves; the short leg doesn’t offset enough. That convexity gap breaks neutrality for large moves, so traders periodically trim or add to legs as rates shift.
Carry is what the trade earns or bleeds when nothing moves, and it’s fundamentally a financing concept. Assume prices near par so coupon ≈ yield. Long $10mm 10-year at 4.50% collects ≈$450k/year, but repo funding at 4.70% costs ≈$470k, so the long leg runs about –$20k. Short $44.7mm 2-year at ~5.00% means you owe roughly that coupon (≈–$2.235mm/year), but you reinvest the short-sale cash at, say, 4.40% (≈+$1.967mm/year), net ≈–$268k. Total carry ≈ –$288k/year. Small changes in repo or reinvest rates can flip that sign, which is why pros model financed yields (coupon minus actual funding) rather than headline yields. Curve trades are funding trades in disguise.
Roll-down is the mechanical price drift from aging. Six months later your “10-year” is a 9.5-year: one coupon is paid out, and the remaining cash flows are repriced at the market yield for 9.5-year risk. If today’s curve were frozen with 10s at 4.50% and 9s at 4.40%, the 9.5-year point sits around 4.45%; that ~5 bp drop adds roughly $4,250 per $1mm notional (≈$42.5k on a $10mm long) purely from curve geometry. The “frozen curve” is an academic baseline to isolate time-decay P&L; in reality the curve is rebuilt continuously as expectations and term premia change. Realized P&L is frozen-curve roll plus whatever the new curve does to the 9.5-year point.
Put together: the trade’s economics are your relative-move view (2s vs 10s) plus convexity drift (managed by periodic resizing) plus financed carry (your meter, driven by repo and reinvest) plus roll-down (time component under a frozen curve, then adjusted by how expectations actually evolve). You stay only if expected shape change beats true carry/funding drag, convexity isn’t skewing risk the wrong way, and there’s still meaningful roll to harvest.
4. Futures
A futures price doesn’t predict where the market is going. It answers a simpler question: what price makes holding the asset equivalent to locking in future delivery?
Two ways to own an asset one year from now:
1. Buy it today at 100, pay to hold it for a year
2. Buy a futures contract today for delivery in one year
The futures price is wherever these two paths cost the same.
Holding an asset has costs and benefits. Costs: you pay interest to finance the purchase, storage fees, insurance. Benefits: you collect dividends, coupons, or the value of having the physical commodity available.
Net carry = Costs minus benefits
The futures price is the spot price adjusted by net carry. If net carry is positive (costs exceed benefits), futures trade above spot. If negative (benefits exceed costs), futures trade below.
Index at 100. Financing costs 5%. Dividends pay 2%. Net carry is 3%.
If the futures price is 106:
– Buy the index at 100
– Finance it at 5% (costs 5)
– Collect dividends at 2% (gain 2)
– Sell futures at 106
– Net result: lock in 3 points of profit with zero risk
Free money. Arbitrageurs pile in until the opportunity vanishes.
If the futures price is 101:
– Short the index at 100 (borrow and sell)
– Invest proceeds at 5% (gain 5)
– Pay dividends on the short at 2% (costs 2)
– Buy futures at 101
– Net result: lock in 2-3 points with zero risk
Again, free money. The trade floods in from the other direction. Competition forces the futures price toward 103—spot plus net carry. At that price, neither strategy offers an edge. The arbitrage disappears.
Equities: Rates at 5%, dividend yield at 2%. Futures trade 3% above the index. The gap compensates you for financing costs minus dividends received.
Bonds: You finance the bond at 4%, it pays a 5% coupon. Futures trade below the bond price because the coupon exceeds financing costs.
Commodities: Oil costs money to store and finance, but you earn nothing holding it. Futures typically trade above spot. Exception: during shortages, having physical oil is worth so much that futures can trade below spot.
Currency forwards: Dollar rates at 5%, euro rates at 3%. The forward euro price adjusts by 2% to eliminate any free lunch from borrowing euros and lending dollars.
Futures price = Spot price + What it costs to carry – What you earn carrying it
